The effectiveness of interventions to disseminate the results of non-commercial randomised clinical trials to healthcare professionals: a systematic review

BACKGROUND

It is unclear how to disseminate the results of randomised controlled trials effectively to health professionals and policymakers to improve treatment, care or prevention through changing policy and practice. This systematic review examined the effectiveness of different methods of dissemination of clinical research results to professional audiences.

METHODS

We systematically reviewed the published and grey literature from 2000 to 2022 for studies assessing different approaches for disseminating clinical study results to professional audiences (health professionals, policymakers and guideline developers). Two reviewers assessed potentially relevant full texts for inclusion. We grouped studies by intervention type, synthesising findings using effect direction plots. Outcomes were grouped into out-takes (e.g. awareness, knowledge, understanding), outcomes (e.g. attitude changes) and impact (changes in policy/practice). The quality of evidence was assessed using GRADE.

RESULTS

Our search identified 13,264 unique records, of which 416 full texts were assessed for eligibility. Of 60 studies that were identified as eligible for inclusion, 20 evaluated the effectiveness of interventions to disseminate clinical research results (13 RCTs, 2 observational studies, 3 pre- and post-intervention surveys and 2 cross-sectional surveys). Studies were grouped by intervention: 7 studies that involved face-to-face meetings between the target audience and trained educators were classified as 'outreach interventions'; 5 studies that provided a summary format for systematic review findings (e.g. summary of findings tables) were grouped together. There was high certainty evidence of a small beneficial impact of outreach interventions on health and moderate certainty evidence of impact on practice (mostly prescribing). There was no evidence of impact on policy and very low certainty around benefits on outcomes and out-takes. We found no consistent benefits of summary formats for systematic review results on outcomes or out-takes (moderate quality evidence). Other interventions with less evidence are reported in the Additional Materials.

CONCLUSIONS

Outreach interventions to disseminate clinical research results can lead to changes in practice and improvements in health. However, these interventions can be resource-intensive. Investment is vital to identify and implement effective and cost-effective ways to disseminate results, so that the potential benefits of trials to patients can be realised.

Muslim women's views and experiences of family planning in Saudi Arabia: a qualitative study

BACKGROUND

Islamic beliefs are associated with decreased contraceptive use compared to other religions, and Muslim women's contraceptive needs are often unmet. Research is needed to provide an in-depth understanding of the complex set of barriers to Muslim women's contraceptive use. Therefore, we aimed to explore Muslim women's awareness and experiences with family planning in Saudi Arabia and investigate barriers to contraceptive use and access to family planning.

METHODS

A qualitative study using semi-structured interviews with women in a public hospital, in Riyadh, Saudi Arabia, between January and June 2019. Data was analysed using reflexive thematic analysis.

RESULTS

Twenty-eight women participated in the study. Women's contraceptive awareness was limited to two methods. Women expressed positive attitudes towards family planning and did not believe it is forbidden in Islam. Barriers to contraception use included lack of knowledge, misconceptions, fear of side effects, family and community and social norms. Many women expressed that they have the right to use contraception, even if their husbands disapprove. Our findings show that healthcare providers rarely offered contraceptive advice, even when requested. Healthcare providers often prescribe oral contraceptives without offering information on other methods available.

CONCLUSION

Our findings suggest that education plays a fundamental role in reproductive autonomy. Men's role in family planning should be encouraged through sharing reproductive responsibility and supporting women's contraceptive choices. Efforts should be directed towards improving women's awareness of different methods of contraception.

Muslim women's perspectives on the barriers to sexually transmitted infections testing and diagnosis in Saudi Arabia

Background

Muslim women are especially vulnerable to sexually transmitted infections (STI) and are at higher risk of under-detection. Evidence on the unique barriers to STI testing and diagnosis among Muslim communities is severely lacking. Understanding the complexity of accessing STI testing and diagnosis in Muslim communities is an area that requires further exploration. We aimed to explore the multilevel barriers to STI testing and diagnosis among Muslim women.

Methods

We conducted qualitative semi-structured interviews informed by the ecological model of health. This study took place in Riyadh Saudi Arabia in 2019 with women aged over 18. Data were analysed using reflexive thematic analysis.

Results

Twenty-eight women were interviewed from different ages, marital status, employment, and educational levels. Muslim women's perceived barriers to STI testing and diagnosis included personal, socio-cultural, and service-level barriers. Lack of knowledge about STIs, denial, and underestimating the seriousness of infection and symptoms were among the many individual barriers to STIs testing and diagnosis. Religious views towards extramarital sex and negative views of people with STIs is a significant barrier to STI testing and diagnosis. Lack of patient confidentiality and providers' judgement and mistreatment were also cited as barriers to seeking healthcare.

Conclusion

Barriers to STI testing and diagnosis exist on many levels including personal, socio-cultural, religious, and healthcare services, and at policy level. Multilevel interventions are needed to reduce the stigma of STIs and facilitate access to sexual health services among Muslims. It is our recommendation that policy and research efforts are directed to enhance trust in the doctor-patient relationship through better clinical training as well as implementing stricter regulations to protect patients' confidentiality in healthcare settings.

The impact of COVID-19 on patient engagement with primary healthcare: lessons from the saudi primary care setting

BACKGROUND

There have been significant achievements in controlling COVID-19 in Saudi Arabia (SA), but as in most healthcare settings worldwide, health services have been seriously disrupted. Also, with pandemic control measures such as lockdowns and curfews, and innovations such as digital health services, the delivery of primary healthcare (PHC) services has dramatically changed. However, little is known about patients' experiences of PHCs during the pandemic, their views on the pandemic-related interventions in SA, and patient views on impact on their medical care.

METHODS

Qualitative semi-structured online interviews were conducted for twenty-four Saudi patients across SA aged 18 and above who were diverse in terms of age, gender, education and health status. Data were analysed using thematic analysis yielding four major themes as an impact of COVID-19 on patient engagement with PHCs.

RESULTS

The COVID-19 pandemic has had profound mixed impacts on patient engagement with PHC in SA. Fear of infection or of breaking lockdown rules has negatively impacted the utilisation of PHCs but positively changed patients' attitudes towards seeking medical help for self-limiting conditions. The pandemic has also negatively impacted routine preventive care at PHCs, especially for patients with long-term health conditions. The mandatory use of some digital health services in SA that existed pre-pandemic has provided patients with a perception of better care during the pandemic. Yet, a lack of awareness of optional digital health services, such as virtual clinics, hindered optimal use. Despite pandemic-related disruption of patient engagement with PHCs, the reduced waiting time in PHC centres and healthcare providers' communication and empathy during the pandemic contributed to patients' perceptions of better care compared to pre-pandemic. However, patients living outside the main cities in SA perceived care quality as less good during the pandemic compared to PHCs in the main cities in SA.

CONCLUSION

The lessons learned from patients' experiences and views of PHCs during the pandemic were beneficial in promoting patient engagement with PHCs. The digital health services mandated in response to the pandemic have accelerated digital health innovation in SA and allowed patients to recognise the benefits of digital health. This has huge potential for increasing continuous patient engagement with PHCs. Yet, patients' experiences of digital health services during the pandemic are essential for informing appropriate implementation and utilisation of e-health services. Patients' positive experiences of PHCs during the pandemic, such as the reduction in waiting times and the perception of improved healthcare providers' professionalism, communication and empathy, can be built on to sustain engagement with PHC services. These findings might have significance for clinicians and policymakers to support patient engagement with PHCs, particularly in healthcare systems like SA that struggle with the overuse of emergency departments (EDs) for PHC-treatable conditions.

School-based relationship and sexuality education intervention engaging adolescent boys for the reductions of teenage pregnancy: the JACK cluster RCT

Background

The need to engage boys in gender-transformative relationships and sexuality education (RSE) to reduce adolescent pregnancy is endorsed by the World Health Organization and the United Nations Educational, Scientific and Cultural Organization.

Objectives

To evaluate the effects of If I Were Jack on the avoidance of unprotected sex and other sexual health outcomes.

Design

A cluster randomised trial, incorporating health economics and process evaluations.

Setting

Sixty-six schools across the four nations of the UK.

Participants

Students aged 13-14 years.

Intervention

A school-based, teacher-delivered, gender-transformative RSE intervention (If I Were Jack) versus standard RSE.

Main outcome measures

Self-reported avoidance of unprotected sex (sexual abstinence or reliable contraceptive use at last sex) after 12-14 months. Secondary outcomes included knowledge, attitudes, skills, intentions and sexual behaviours.

Results

The analysis population comprised 6556 students: 86.6% of students in the intervention group avoided unprotected sex, compared with 86.4% in the control group {adjusted odds ratio 0.85 [95% confidence interval (CI) 0.58 to 1.26], p = 0.42}. An exploratory post hoc analysis showed no difference for sexual abstinence [78.30% intervention group vs. 78.25% control group; adjusted odds ratio 0.85 (95% CI 0.58 to 1.24), p = 0.39], but more intervention group students than control group students used reliable contraception at last sex [39.62% vs. 26.36%; adjusted odds ratio 0.52 (95% CI 0.29 to 0.920), p = 0.025]. Students in schools allocated to receive the intervention had significantly higher scores on knowledge [adjusted mean difference 0.18 (95% CI 0.024 to 0.34), p = 0.02], gender-equitable attitudes and intentions to avoid unintended pregnancy [adjusted mean difference 0.61 (95% CI 0.16 to 1.07), p = 0.01] than students in schools allocated to receive the control. There were positive but non-significant differences in sexual self-efficacy and communication skills. The total mean incremental cost of the intervention compared with standard RSE was £2.83 (95% CI -£2.64 to £8.29) per student. Over a 20-year time horizon, the intervention is likely to be cost-effective owing to its impact on unprotected sex because it would result in 379 (95% CI 231 to 477) fewer unintended pregnancies, 680 (95% CI 189 to 1467) fewer sexually transmitted infections and a gain of 10 (95% CI 5 to 16) quality-adjusted life-years per 100,000 students for a cost saving of £9.89 (95% CI -£15.60 to -£3.83).

Limitations

The trial is underpowered to detect some effects because four schools withdrew and the intraclass correlation coefficient (0.12) was larger than that in sample size calculation (0.01).

Conclusions

We present, to our knowledge, the first evidence from a randomised trial that a school-based, male engagement gender-transformative RSE intervention, although not effective in increasing avoidance of unprotected sex (defined as sexual abstinence or use of reliable contraception at last sex) among all students, did increase the use of reliable contraception at last sex among students who were, or became, sexually active by 12-14 months after the intervention. The trial demonstrated that engaging all adolescents early through RSE is important so that, as they become sexually active, rates of unprotected sex are reduced, and that doing so is likely to be cost-effective.

Future work

Future studies should consider the longer-term effects of gender-transformative RSE as students become sexually active. Gender-transformative RSE could be adapted to address broader sexual health and other settings.

Muslim women's knowledge, views, and attitudes towards sexually transmitted infections in Saudi Arabia: A qualitative study

BACKGROUND

The cultural sensitivity surrounding sexuality in Islamic communities has an impact on awareness and prevention of sexually transmitted infections (STIs). This study explores Muslim women's knowledge, views, and attitudes towards STIs and people living with HIV/AIDs in Saudi Arabia.

METHODS

We conducted qualitative semi-structured interviews with Muslim women from Saudi Arabia. Interviews took place in a public hospital in Riyadh, Saudi Arabia in 2019. Data were transcribed, coded, and analysed using a reflexive thematic analysis.

RESULTS

Twenty-eight women were interviewed, the majority were college educated and employed. Participants lacked knowledge about STIs, and there were significant misconceptions. The majority of women expressed extremely negative attitudes towards STIs, particularly towards people living with HIV/AIDS. Participants believed that judgemental attitudes and stigmatisation of people with HIV/AIDS were justified if an infection was transmitted through extramarital sex. Men were believed to be the source of STIs, and STIs were viewed as punishment from God for extramarital sexual relations that are forbidden in Islam. Protection against STIs was believed to be achieved by strengthening religious beliefs.

CONCLUSION

Attitudes towards people with STIs, HIV/AIDS in particular, were highly influenced by religious views towards extramarital sex, as well as lack of knowledge and misconceptions. There is an urgent need for accurate information and improved awareness of sexual health including STIs among Muslims in Saudi Arabia. Public health efforts should be directed towards reducing stigma and discrimination against people living with HIV/AIDS in Saudi Arabia and other Islamic communities.

A peer-led, school-based social network intervention for young people in the UK, promoting sexual health via social media and conversations with friends: intervention development and optimisation of STASH

BACKGROUND

The quality of school-based sex and relationships education (SRE) is variable in the UK. Digitally-based interventions can usefully supplement teacher-delivered lessons and positively impact sexual health knowledge. Designed to address gaps in core SRE knowledge, STASH (Sexually Transmitted infections And Sexual Health) is a peer-led social network intervention adapted from the successful ASSIST (A Stop Smoking in Schools Trial) model, and based on Diffusion of Innovation theory. This paper describes how the STASH intervention was developed and refined.

METHODS

Drawing on the Six Steps in Quality Intervention Development (6SQuID) framework, we tested a provisional programme theory through three iterative stages -: 1) evidence synthesis; 2) intervention co-production; and 3) adaptation - which incorporated evidence review, stakeholder consultation, and website co-development and piloting with young people, sexual health specialists, and educators. Multi-method results were analysed in a matrix of commonalities and differences.

RESULTS

Over 21 months, intervention development comprised 20 activities within the three stages. 1) We identified gaps in SRE provision and online resources (e.g. around sexual consent, pleasure, digital literacy), and confirmed critical components including the core ASSIST peer nomination process, the support of schools, and alignment to the national curriculum. We reviewed candidate social media platforms, ruling out all except Facebook on basis of functionality restrictions which precluded their use for our purposes. 2) Drawing on these findings, as well as relevant behaviour change theories and core elements of the ASSIST model, we co-developed new content with young people and other stakeholders, tailored to sexual health and to delivery via closed Facebook groups, as well as face-to-face conversations. 3) A pilot in one school highlighted practical considerations, including around peer nomination, recruitment, awareness raising, and boundaries to message sharing. From this, a revised STASH intervention and programme theory were co-developed with stakeholders.

CONCLUSIONS

STASH intervention development required extensive adaptation from the ASSIST model. Although labour intensive, our robust co-development approach ensured that an optimised intervention was taken forward for feasibility testing. Evidencing a rigorous approach to operationalising existing intervention development guidance, this paper also highlights the significance of balancing competing stakeholder concerns, resource availability, and an ever-changing landscape for implementation.

Interventions to support contraceptive choice and use: a global systematic map of systematic reviews

BACKGROUND

To review the highest level of available evidence, a systematic map identified systematic reviews that evaluated the effectiveness of interventions to improve contraception choice and increase contraception use.

METHODS

Systematic reviews published since 2000 were identified from searches of nine databases. Data were extracted using a coding tool developed for this systematic map. Methodological quality of included reviews was assessed using AMSTAR 2 criteria.

FINDINGS AND CONCLUSION

Fifty systematic reviews reported evaluations of interventions for contraception choice and use addressing three domains (individual, couples, community); Meta-analyses in 11 of the reviews mostly addressed interventions for individuals. We identified 26 reviews covering High Income Countries, 12 reviews covering Low Middle-Income Countries and the rest a mix of both. Most reviews (15) focussed on psychosocial interventions, followed by incentives (6) and m-health interventions (6). The strongest evidence from meta-analyses is for the effectiveness of motivational interviewing, contraceptive counselling, psychosocial interventions, school-based education, and interventions promoting contraceptive access, demand-generation interventions (community and facility based, financial mechanisms and mass media), and mobile phone message interventions. Even in resource constrained settings, community-based interventions can increase contraceptive use. There are gaps in the evidence on interventions for contraception choice and use, and limitations in study designs and lack of representativeness. Most approaches focus on individual women rather than couples or wider socio-cultural influences on contraception and fertility. This review identifies interventions which work to increase contraception choice and use, and these could be implemented in school, healthcare or community settings.

Exploring the psychosexual impact and disclosure experiences of women testing positive for high-risk cervical human papillomavirus

OBJECTIVES

To examine the psychosexual impact and disclosure experiences of women testing HPV-positive following cervical screening.

DESIGN

In-depth semi-structured interviews.

METHODS

Interviews were conducted with 21 women of screening age (i.e. those aged 24-65 years) in England who self-reported testing HPV-positive in the context of cervical screening in the last 12 months. Data were analysed using Framework Analysis.

RESULTS

The sexually transmitted nature of HPV, and aspects relating to the transmission of HPV and where their HPV infection had come from, had an impact on women's current, past and future interpersonal and sexual relationships. Most women had disclosed their HPV infection to others, however the factors influencing their decision, and others' reactions to disclosure differed. The magnitude and extent of psychosexual impact was influenced by how women conceptualized HPV, their understanding of key aspects of the virus, concerns about transmitting HPV and having a persistent HPV infection.

CONCLUSIONS

Increasing knowledge of key aspects of HPV, such as its high prevalence and spontaneous clearance, and the differences between HPV and other STIs, may increase women's understanding of their screening result and reduce any negative psychosexual consequences of testing HPV-positive. Referring to HPV as an infection that is passed on by skin-to-skin contact during sexual activity, rather than an STI, may help to lessen any psychosexual impact triggered by the STI label.

Behavioural intervention to reduce sexually transmitted infections in people aged 16–24 years in the UK: the safetxt RCT

Background

The prevalence of genital chlamydia and gonorrhoea is higher in the 16–24 years age group than those in other age group. With users, we developed the theory-based safetxt intervention to reduce sexually transmitted infections.

Objectives

To establish the effect of the safetxt intervention on the incidence of chlamydia/gonorrhoea infection at 1  year.

Design

A parallel-group, individual-level, randomised superiority trial in which care providers and outcome assessors were blinded to allocation.

Setting

Recruitment was from 92 UK sexual health clinics.

Participants

Inclusion criteria were a positive chlamydia or gonorrhoea test result, diagnosis of non-specific urethritis or treatment started for chlamydia/gonorrhoea/non-specific urethritis in the last 2 weeks; owning a personal mobile phone; and being aged 16–24 years.

Allocation

Remote computer-based randomisation with an automated link to the messaging system delivering intervention or control group messages.

Intervention

The safetxt intervention was designed to reduce sexually transmitted infection by increasing partner notification, condom use and sexually transmitted infection testing before sex with new partners. It employed educational, enabling and incentivising content delivered by 42–79 text messages over 1 year, tailored according to type of infection, gender and sexuality.

Comparator

A monthly message regarding trial participation.

Main outcomes

The primary outcome was the incidence of chlamydia and gonorrhoea infection at 12 months, assessed using nucleic acid amplification tests. Secondary outcomes at 1 and 12 months included self-reported partner notification, condom use and sexually transmitted infection testing prior to sex with new partner(s).

Results

Between 1 April 2016 and 23 November 2018, we assessed 20,476 people for eligibility and consented and randomised 6248 participants, allocating 3123 to the safetxt intervention and 3125 to the control. Primary outcome data were available for 4675 (74.8%) participants. The incidence of chlamydia/gonorrhoea infection was 22.2% (693/3123) in the intervention group and 20.3% (633/3125) in the control group (odds ratio 1.13, 95% confidence interval 0.98 to 1.31). There was no evidence of heterogeneity in any of the prespecified subgroups. Partner notification was 85.6% in the intervention group and 84.0% in the control group (odds ratio 1.14, 95% confidence interval 0.99 to 1.33). At 12 months, condom use at last sex was 33.8% in the intervention group and 31.2% in the control group (odds ratio 1.14, 95% confidence interval 1.01 to 1.28) and condom use at first sex with most recent new partner was 54.4% in the intervention group and 48.7% in the control group (odds ratio 1.27, 95% confidence interval 1.11 to 1.45). Testing before sex with a new partner was 39.5% in the intervention group and 40.9% in the control group (odds ratio 0.95, 95% confidence interval 0.82 to 1.10). Having two or more partners since joining the trial was 56.9% in the intervention group and 54.8% in the control group (odds ratio 1.11, 95% confidence interval 1.00 to 1.24) and having sex with someone new since joining the trial was 69.7% in the intervention group and 67.4% in the control group (odds ratio 1.13, 95% confidence interval 1.00 to 1.28). There were no differences in safety outcomes. Additional sensitivity and per-protocol analyses showed similar results.

Limitations

Our understanding of the mechanism of action for the unanticipated effects is limited.

Conclusions

The safetxt intervention did not reduce chlamydia and gonorrhoea infections, with slightly more infections in the intervention group. The intervention increased condom use but also increased the number of partners and new partners. Randomised controlled trials are essential for evaluating health communication interventions, which can have unanticipated effects.

Future work

Randomised controlled trials evaluating novel interventions in this complex area are needed.

Factors affecting contraceptive choice in women over 40: a qualitative study

OBJECTIVE

To explore the views of women over 40 years in choosing and using contraception, and to inform how contraceptive counselling for this age group could be improved.

DESIGN, SETTING AND PARTICIPANTS

Fourteen women aged 40-52 years were recruited through social media platforms to take part in online, semistructured, in-depth interviews. Transcripts were analysed using a qualitative thematic approach.

RESULTS

(1) Participants were anxious about unplanned pregnancy, and still highly motivated to avoid this. (2) Changes of contraceptive method over the lifecourse were occasionally precipitated by emergent health conditions, but healthcare providers often recommended a change in method on the basis of age alone. (3) Participants were experiencing perimenopausal symptoms but were largely unaware of how hormonal contraception could be used to treat these symptoms. (4) Prior negative experiences with contraceptive methods, coercive experiences with healthcare providers, and traumatic life events all contributed to a narrowing of contraceptive preference in later life.

CONCLUSION

Women over 40 years may be highly motivated to avoid pregnancy. This age group may have complex contraceptive histories with emerging perimenopausal symptoms. Women over 40 years may have accumulated adverse experiences which impact their contraceptive choices. These factors need to be explored by clinicians, to facilitate shared decision-making.

An Intervention to Increase Condom Use Among Users of STI Self-Sampling Websites (Wrapped): Protocol for a Randomized Controlled Feasibility Trial (Preprint)

BACKGROUND

Reducing the rates of sexually transmitted infections (STIs) among young people is a public health priority. The best way to avoid STIs from penetrative sex is to use a condom, but young people report inconsistent use. A missed opportunity to intervene to increase condom use is when young people access self-sampling kits for STIs through the internet. The potential of this opportunity is enhanced by the increasing numbers of young people being tested through this route every year in England. Hence, in a cocreation by young people, stakeholders, and researchers, Wrapped was developed--a fully automated, multicomponent, and interactive digital behavior change intervention developed for users of STI self-sampling websites, who are aged 16-24 years.

OBJECTIVE

This paper is a protocol for a feasibility randomized controlled trial (fRCT). The fRCT seeks to establish whether it is feasible to run a randomized controlled trial to test the effectiveness and cost-effectiveness of Wrapped. Wrapped aims to reduce the incidence of STIs through increasing correct and consistent use of condoms among users of STI self-sampling websites, who are aged 16-24 years.

METHODS

A 2-arm parallel-group randomized fRCT of Wrapped plus usual care, compared to usual care only (basic information on STIs and condom use), with a nested qualitative study. A minimum of 230 participants (aged 16-24 years) are recruited from an existing chlamydia self-sampling website. Participants are randomized into 1 of 2 parallel groups (1:1 allocation). Primary outcomes are the percentage of users recruited to the fRCT and the percentage of randomized participants who return a chlamydia self-sampling kit at month 12. Additionally, besides chlamydia positivity based on biological samples, surveys at baseline, month 3, month 6, and month 12, are used to assess condom use attitude, behavioral capability, self-efficacy, and intention, along with details of any partnered sexual activity and condom use, and health economic data. Nested qualitative interviews with trial participants are used to gain insight into the factors affecting recruitment and attrition.

RESULTS

Recruitment to the fRCT began in March 2021 and was completed in October 2021. Data collection was completed in December 2022.

CONCLUSIONS

This feasibility study will provide data to inform the design of a future-definitive trial. This work is timely given a rapid rise in the use of internet testing for STIs and the sustained high levels of STIs among young people.

Effectiveness of a behavioural intervention delivered by text messages (safetxt) on sexually transmitted reinfections in people aged 16-24 years: randomised controlled trial

OBJECTIVE

To quantify the effects of a series of text messages (safetxt) delivered in the community on incidence of chlamydia and gonorrhoea reinfection at one year in people aged 16-24 years.

DESIGN

Parallel group randomised controlled trial.

SETTING

92 sexual health clinics in the United Kingdom.

PARTICIPANTS

People aged 16-24 years with a diagnosis of, or treatment for, chlamydia, gonorrhoea, or non-specific urethritis in the past two weeks who owned a mobile phone.

INTERVENTIONS

3123 participants assigned to the safetxt intervention received a series of text messages to improve sex behaviours: four texts daily for days 1-3, one or two daily for days 4-28, two or three weekly for month 2, and 2-5 monthly for months 3-12. 3125 control participants received a monthly text message for one year asking for any change to postal or email address. It was hypothesised that safetxt would reduce the risk of chlamydia and gonorrhoea reinfection at one year by improving three key safer sex behaviours: partner notification at one month, condom use, and sexually transmitted infection testing before unprotected sex with a new partner. Care providers and outcome assessors were blind to allocation.

MAIN OUTCOME MEASURES

The primary outcome was the cumulative incidence of chlamydia or gonorrhoea reinfection at one year, assessed by nucleic acid amplification tests. Safety outcomes were self-reported road traffic incidents and partner violence. All analyses were by intention to treat.

RESULTS

6248 of 20 476 people assessed for eligibility between 1 April 2016 and 23 November 2018 were randomised. Primary outcome data were available for 4675/6248 (74.8%). At one year, the cumulative incidence of chlamydia or gonorrhoea reinfection was 22.2% (693/3123) in the safetxt arm versus 20.3% (633/3125) in the control arm (odds ratio 1.13, 95% confidence interval 0.98 to 1.31). The number needed to harm was 64 (95% confidence interval number needed to benefit 334 to ∞ to number needed to harm 24) The risk of road traffic incidents and partner violence was similar between the groups.

CONCLUSIONS

The safetxt intervention did not reduce chlamydia and gonorrhoea reinfections at one year in people aged 16-24 years. More reinfections occurred in the safetxt group. The results highlight the need for rigorous evaluation of health communication interventions.

Factors influencing contraception choice and use globally: a synthesis of systematic reviews

BACKGROUND

Unintended pregnancy has a huge adverse impact on maternal, child and family health and wealth. There is an unmet need for contraception globally, with an estimated 40% of pregnancies unintended worldwide.

METHODS

We systematically searched PubMed and specialist databases for systematic reviews addressing contraceptive choice, uptake or use, published in English between 2000 and 2019. Two reviewers independently selected and appraised reports and synthesised quantitative and qualitative review findings. We mapped emergent themes to a social determinants of health framework to develop our understanding of the complexities of contraceptive choice and use.

FINDINGS

We found 24 systematic reviews of mostly moderate or high quality. Factors affecting contraception use are remarkably similar among women in very different cultures and settings globally. Use of contraception is influenced by the perceived likelihood and appeal of pregnancy, and relationship status. It is influenced by women's knowledge, beliefs, and perceptions of side effects and health risks. Male partners have a strong influence, as do peers' views and experiences, and families' expectations. Lack of education and poverty is linked with low contraception use, and social and cultural norms influence contraception and expectations of family size and timing. Contraception use also depends upon their availability, the accessibility, confidentiality and costs of health services, and attitudes, behaviour and skills of health practitioners.

INTERPRETATION

Contraception has remarkably far-reaching benefits and is highly cost-effective. However, women worldwide lack sufficient knowledge, capability and opportunity to make reproductive choices, and health care systems often fail to provide access and informed choice.

Sexual and reproductive health knowledge, perceptions and experiences of women in Saudi Arabia: a qualitative study

BACKGROUND

There is no formal sexual and reproductive health (SRH) education currently offered in Saudi Arabia. Lack of knowledge and misconceptions are evident among Saudi women, which can lead to negative sexual and reproductive experiences. The aim of this study is to explore Saudi women's SRH knowledge, perceptions and experiences.

METHODS

Qualitative semi-structured interviews with Saudi women were conducted. Interviews took place in a public hospital in Riyadh, Saudi Arabia. Interviews were conducted in Arabic, recorded and transcribed verbatim, to allow for thematic analysis of the data. The following themes were identified: experience with menarche, deep-rooted negative views towards sex, difficulty discussing SRH topics, knowledge of sex and reproduction, generational gap, sources of SRH information and the role of the mother.

RESULTS

A total of 28 women, both married and unmarried, aged 20-50 years were interviewed. A profound lack of SRH knowledge was observed among Saudi women which contributed greatly to negative experiences both in childhood and adulthood. Lack of knowledge about menstruation often caused emotional distress for young girls, and menarche was associated with bad memories and negative emotions. Lack of knowledge about sexual intercourse and the deep-rooted negative views towards sex were linked with physical and psychological issues for women. Women rarely received information from their parents or teachers and preferred the internet for their SRH information.

CONCLUSION

There is a substantial unmet need for SRH education for women in Saudi Arabia. It is our recommendation that SRH education should be tailored to meet Saudi women's unique needs, while understanding specific socio-cultural barriers to SRH education and discussions. Research and policy efforts should be directed towards regulating and producing evidence-based health information on the internet, particularly Arabic language websites.

Views, attitudes and experiences of South Asian women concerning sexual health services in the UK: a qualitative study

OBJECTIVE

To explore the views, attitudes, and experiences of South Asian women in the UK regarding sexual health services.

METHODS

We performed virtual semi-structured interviews with South Asian women 18 and over living in the UK. We explored participants' experiences of accessing sexual health services, including contraception, smear tests and sexually transmitted infection (STI) tests. We coded interview transcripts and analysed them thematically.

RESULTS

From February to April 2021, we conducted 14 interviews with South Asian women between the ages of 18 and 40 living in England and Wales, from February to April 2021. We identified four overarching themes: Access to sexual health services, entry to sexual health services, quality of sexual health services and stigma associated with sexual health services. Important barriers to sexual health services include limited knowledge of local provision, stigma and shame, and concerns about confidentiality. Participants found it difficult to discuss their sexual health (with anyone) and were often being met with judgement and a lack of partnership from clinicians.

CONCLUSION

Our results suggest that South Asian women are uncomfortable accessing sexual health services and communicating their sexual health concerns with health care professionals. Service providers should collaborate with community-based organisations to ensure that services are discrete, confidential, and culturally appropriate.

Causal explanations for patient engagement with primary care services in Saudi Arabia: a realist review protocol

INTRODUCTION

Saudi Arabia (SA) has a rapidly developing universal healthcare system which is maturing from its hospital focused origins. However, health service usage suggests that up to 65% of the cases seen in emergency departments were classified as non-urgent and could have been appropriately managed in primary healthcare (PHC) settings. Primary care development in SA has lagged behind secondary care, and evidence suggests that Saudi citizens are currently ambivalent or dissatisfied with their PHC services. Previous research has focused on the quality and patient satisfaction of PHC services in SA. Yet, uncertainty still exists about causal explanations for patient engagement with PHC services and what refinements are needed for PHC. Less attention has been paid to how patient engagement strategies might work differently, which is increasingly recognised as important in PHC services. The aim of this review is to understand the causal explanations for patient engagement with PHC and to generate theory of how the intended outcome of patient engagement with PHC in SA might be achieved through identified contexts and mechanisms.

METHODS AND ANALYSIS

A realist review approach will be used to synthesise the evidence. Databases including Medline, EMBASE and CINAHL will be searched. Literature will be included if it has relevance to the research question, and is trustworthy in nature. All document types will be screened including peer reviewed articles, relevant grey literature and related media items. All study types will be included. Stakeholders' feedback will also inform our review. A realist approach is suitable for this review because patient engagement with PHC services is a complex phenomenon. A range of different relevant data will be included in the following stages: developing an initial programme theory, searching the evidence, selecting data, extracting data, synthesising data and refining the programme theory.

ETHICS AND DISSEMINATION

This study will use secondary data, and stakeholders are involved only to shape our understanding of the important contexts in patient engagement; hence, a formal ethics review is not required. Findings will be disseminated in a peer-reviewed journal and at relevant conferences.

Feasibility study of peer-led and school-based social network Intervention (STASH) to promote adolescent sexual health

Background

Effective sex education is the key to good sexual health. Peer-led approaches can augment teacher-delivered sex education, but many fail to capitalise on mechanisms of social influence. We assessed the feasibility of a novel intervention (STASH) in which students (aged 14–16) nominated as influential by their peers were recruited and trained as Peer Supporters (PS). Over a 5–10-week period, they spread positive sexual health messages to friends in their year group, both in-person and via social media, and were supported to do so via weekly trainer-facilitated meetings. The aims of the study were to assess the feasibility of STASH (acceptability, fidelity and reach), to test and refine the programme theory and to establish whether the study met pre-set progression criteria for continuation to larger-scale evaluation.

Methods

The overall design was a non-randomised feasibility study of the STASH intervention in 6 schools in Scotland. Baseline (n=680) and follow-up questionnaires (approx. 6 months later; n=603) were administered to the intervention year group. The control group (students in year above) completed the follow-up questionnaire only (n=696), 1 year before the intervention group. The PS (n=88) completed a brief web survey about their experience of the role; researchers interviewed participants in key roles (PS (n=20); PS friends (n=22); teachers (n=8); trainers (n=3)) and observed 20 intervention activities. Activity evaluation forms and project monitoring data also contributed information. We performed descriptive quantitative analysis and thematic qualitative analysis.

Results

The PS role was acceptable; on average across schools >50% of students nominated as influential by their friends, signed up and were trained (n=104). This equated to 13% of the year group. Trained PS rarely dropped out (97% completion rate) and 85% said they liked the role. Fidelity was good (all bar one trainer-led activity carried out; PS were active). The intervention had good reach; PS were reasonably well connected and perceived as ‘a good mix’ and 58% of students reported exposure to STASH. Hypothesised pre-conditions, contextual influences and mechanisms of change for the intervention were largely confirmed. All bar one of the progression criteria was met.

Conclusion

The weight of evidence supports continuation to full-scale evaluation.

Interactive digital interventions for prevention of sexually transmitted HIV

BACKGROUND

Digital technology offers good opportunities for HIV prevention. This systematic review assesses the effectiveness of interactive digital interventions (IDIs) for prevention of sexually transmitted HIV.

METHODS

We conducted a systematic search for randomized controlled trials (RCTs) of IDIs for HIV prevention, defining 'interactive' as producing personally tailored material. We searched databases including the Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, CINAHL, PsycINFO, grey literature, reference lists, and contacted authors if needed.Two authors screened abstracts, applied eligibility and quality criteria and extracted data. Meta-analyses used random-effects models with standardized mean differences (SMD) for continuous outcomes and odds ratios (OR) for binary outcomes, assessing heterogeneity using the I2 statistic.

RESULTS

We included 31 RCTs of IDIs for HIV prevention. Meta-analyses of 29 RCTs comparing IDIs with minimal interventions (e.g. leaflet, waiting list) showed a moderate increase in knowledge (SMD 0.56, 95% CI 0.33 to 0.80), no effect on self-efficacy (SMD 0.13, 95% CI 0.00 to 0.27), a small improvement in intention (SMD 0.16, 95% CI 0.06 to 0.26), improvement in HIV prevention behaviours (OR 1.28, 95% CI 1.04 to 1.57) and a possible increase in viral load, but this finding is unreliable.We found no evidence of difference between IDIs and face-to-face interventions for knowledge, self-efficacy, intention, or HIV-related behaviours in meta-analyses of five small RCTs. We found no health economic studies.

CONCLUSION

There is good evidence that IDIs have positive effects on knowledge, intention and HIV prevention behaviours. IDIs are appropriate for HIV prevention in a variety of settings.Supplementary Video Abstract, http://links.lww.com/QAD/B934.

Peer-to-Peer Sharing of Social Media Messages on Sexual Health in a School-Based Intervention: Opportunities and Challenges Identified in the STASH Feasibility Trial

BACKGROUND

There is a strong interest in the use of social media to spread positive sexual health messages through social networks of young people. However, research suggests that this potential may be limited by a reluctance to be visibly associated with sexual health content on the web or social media and by the lack of trust in the veracity of peer sources.

OBJECTIVE

The aim of this study was to investigate opportunities and challenges of using social media to facilitate peer-to-peer sharing of sexual health messages within the context of STASH (Sexually Transmitted Infections and Sexual Health), a secondary school-based and peer-led sexual health intervention.

METHODS

Following training, and as a part of their role, student-nominated peer supporters (aged 14-16 years) invited school friends to trainer-monitored, private Facebook groups. Peer supporters posted curated educational sex and relationship content within these groups. Data came from a feasibility study of the STASH intervention in 6 UK schools. To understand student experiences of the social media component, we used data from 11 semistructured paired and group interviews with peer supporters and their friends (collectively termed students; n=42, aged 14-16 years), a web-based postintervention questionnaire administered to peer supporters (n=88), and baseline and follow-up questionnaires administered to students in the intervention year group (n=680 and n=603, respectively). We carried out a thematic analysis of qualitative data and a descriptive analysis of quantitative data.

RESULTS

Message sharing by peer supporters was hindered by variable engagement with Facebook. The trainer-monitored and private Facebook groups were acceptable to student members (peer supporters and their friends) and reassuring to peer supporters but led to engagement that ran parallel to-rather than embedded in-their routine social media use. The offline context of a school-based intervention helped legitimate and augment Facebook posts; however, even where friends were receptive to STASH messages, they did not necessarily engage visibly on social media. Preferences for content design varied; however, humor, color, and text brevity were important. Preferences for social media versus offline message sharing varied.

CONCLUSIONS

Invitation-only social media groups formed around peer supporters' existing friendship networks hold potential for diffusing messages in peer-based sexual health interventions. Ideally, interactive opportunities should not be limited to single social media platforms and should run alongside offline conversations. There are tensions between offering young people autonomy to engage flexibly and authentically and the need for adult oversight of activities for information accuracy and safeguarding.

Participant views and experiences of sexual health research: The Contraception Choices online trial

BACKGROUND

Online sexual health research can be convenient, efficient and low cost, but there are debates about the adequacy of online informed consent, privacy, and the acceptability of different methods of follow-up.

OBJECTIVES

To explore women's views and experiences of the Contraception Choices feasibility trial procedures and the place of digital interventions for contraception decision making.

METHODS

We analysed data from two sources: (1) Qualitative interviews. Eighteen interviews were conducted with women who had taken part in the Contraception Choices pre-trial feasibility study, to evaluate recruitment and online trial procedures. (2) Free-text comments. Women in the main Contraception Choices randomised controlled trial were followed up at 3 and 6 months, and asked 'Please tell us what you liked or disliked about the website' and 'Has being in the study had any good or bad effects on your life?' A total of 387 and 414 comments were made at 3 and 6 months respectively. Data were analysed thematically.

RESULTS

Participants liked being involved in a study about contraception, although recruitment from an abortion clinic was less acceptable than in other sexual health settings. Women found the trial procedures straightforward, and expressed no major concerns about online self-registration, informed consent or online data collection. Online survey questions about contraception and fertility were acceptable, and participants liked the convenience of being followed up by email or text.

CONCLUSIONS

Participants appreciated the advantages of the online research design and did not express concerns about consent or privacy. Women would welcome digital interventions for contraception in a variety of settings.

Sexually transmitted infection knowledge and attitudes among Muslim women worldwide: a systematic review

Extramarital sexual relations are forbidden in Islam, and sexual health information is not readily available in Islamic communities, especially for women. This review aimed to explore sexually transmitted infection (STI) knowledge and attitudes among Muslim women worldwide. A systematic review was conducted on seven electronic databases. We included qualitative and quantitative studies of female Muslim participants of reproductive age, focusing on STI knowledge and attitudes. A narrative synthesis approach was used with thematic analysis methods. Eighteen studies conducted in 13 countries were included. Three main themes were identified: poor knowledge and misconceptions; sources of sexual health information and information needs; and cultural influences on STI knowledge and attitudes. Generally, Muslim women had poor knowledge regarding STI signs and symptoms, prevention, diagnosis and treatment, in addition to many misconceptions. Negative attitudes towards people infected with HIV/AIDS were common, and attitudes were highly influenced by misconceptions and insufficient knowledge. Infected women tended to be subjected to more blame and judgement compared to men. While the review summarises knowledge and attitudes of Muslim women worldwide, we excluded studies that did not clearly state that the study participants were Muslim women, hence many countries with Muslim populations are not represented in this review. Negative attitudes towards STIs make it harder for women to access sexual health information, STI prevention and treatment. This review highlights the need for culturally sensitive sexual health education for Muslim women. Future sex education interventions would benefit from considering the wider personal and external barriers.

An interactive website to aid young women's choice of contraception: feasibility and efficacy RCT

BACKGROUND

Effective use of contraception can reduce numbers of unintended pregnancies, but misunderstandings and concerns about contraception abound. Increasingly, women seek health-care information online.

OBJECTIVES

To develop an interactive website to aid informed choice of contraceptive method, including long-acting reversible contraception (Phase I), and test its effectiveness in a parallel, single-blind randomised trial (Phase II). Approval came from London - Camden & King's Cross Research Ethics Committee (reference 17/LO/0112).

SETTING AND PARTICIPANTS

For both phases, women aged 15-30 years were recruited from general practice, sexual health services, maternity services, community pharmacies and an abortion service.

DESIGN

In Phase I, we conducted three systematic literature reviews, a review of YouTube (YouTube, LLC, San Bruno, CA, USA) videos about contraception, and focus groups and interviews with young women to explore barriers to and concerns and misperceptions about contraception. We then iteratively co-designed an interactive website, Contraception Choices [URL: www.contraceptionchoices.org (accessed June 2020)], with young women and a software company. In Phase II, we evaluated the website through a randomised trial that began as a feasibility trial. Early demand for Contraception Choices stimulated a design change from a feasibility to an efficacy trial, with follow-up for clinical outcomes at 3 and 6 months. A randomisation list was incorporated into the trial software program to allocate participants to the intervention (website) or control group (standard care).

INTERVENTION

Contraception Choices is a co-designed, evidence-based, interactive website to aid informed choice of contraception. It provides information about different methods, addresses common concerns and offers tailored contraceptive options in response to individual preferences.

MAIN OUTCOME MEASURES

Qualitative - participant views and experience of the intervention, assessed through qualitative interviews. Quantitative primary outcomes - follow-up rate at 6 months in the initial feasibility trial, using a long-acting reversible contraception method, and satisfaction with contraceptive method at 6 months in the efficacy trial.

RESULTS

A total of 927 women were randomised online to the website (n = 464) or control group (n = 463), of whom 739 (80%) provided follow-up data at 6 months [786 women (85%) provided data at 3 and/or 6 months that were included in the analysis of primary outcomes]. There was little difference between groups in the proportion using long-acting reversible contraception at 6 months [30.4% intervention vs. 31.0% control, adjusted odds ratio after imputation 0.87 (95% confidence interval 0.60 to 1.27)] or in satisfaction with contraceptive method [proportion being 'satisfied' or 'very satisfied', 82.6% intervention vs. 82.1% control, adjusted odds ratio 0.93 (95% confidence interval 0.69 to 1.25)]. Qualitative evaluation indicated highly positive views about the website and increased knowledge of contraceptive methods that could dispel misperceptions. Women appreciated having information tailored to their specific needs and felt better prepared before consultations.

LIMITATIONS

We did not include intermediate measures, such as knowledge of contraceptive methods, intention to change method or confidence in discussing contraception with a health-care professional, which may have indicated other benefits of using the website. In future, the website should be studied in different settings (e.g. schools and in routine practice) to see whether or not it improves the quality or efficiency of contraceptive consultations.

CONCLUSIONS

Our systematic review indicated wide-ranging influences on women's use of contraception globally. The website, Contraception Choices, was very popular with young women and contraception service providers. It was not associated with statistically significant differences in use of long-acting reversible contraception or satisfaction with contraceptive method at 6 months.

A peer-led intervention to promote sexual health in secondary schools: the STASH feasibility study

Background

Young people report higher levels of unsafe sex and have higher rates of sexually transmitted infections than any other age group. Schools are well placed to facilitate early intervention, but more effective approaches are required. Peer-led approaches can augment school-based education, but often fail to capitalise on mechanisms of social influence. The potential of using social media in sexual health has not been tested in school settings.

Objectives

Finalise the design of the Sexually Transmitted infections And Sexual Health (STASH) intervention; assess the recruitment and retention of peer supporters, and acceptability to participants and stakeholders; assess the fidelity and reach, in addition to the barriers to and facilitators of, implementation; refine programme theory; understand the potential of social media; determine design parameters for a future randomised controlled trial, including economic evaluation; and establish whether or not progression criteria were met.

Design

This was a feasibility study comprising intervention development and refinement of the STASH pilot and non-randomised feasibility trial in six schools. Control data were provided by students in the year above the intervention group.

Setting

Secondary schools in Scotland.

Participants

Students aged 14–16 years, teachers and intervention delivery partners.

Interventions

The STASH intervention was adapted from A Stop Smoking In Schools Trial (ASSIST) (an effective peer-led smoking intervention). Based on diffusion of innovation theory, the STASH study involves peer nomination to identify the most influential students, with the aim of recruiting and training 15% of the year group as peer supporters. The peer supporters deliver sexual health messages to friends in their year group via conversations and use of Facebook (www.facebook.com; Facebook, Inc., Menlo Park, CA, USA) to share varied content from a curated set of web-based resources. Peer supporters are given support themselves via follow-up sessions and via trainer membership of Facebook groups.

Main outcome measures

The primary outcome was whether or not progression criteria were met in relation to intervention acceptability and feasibility. The study also piloted indicative primary outcomes for a full-scale evaluation.

Data sources

Peer supporter questionnaire; observations of activities; interviews with trainers, teachers, peer supporters and students; monitoring log of peer supporter activities (including on Facebook and meeting attendance); questionnaire to control year group (baseline characteristics, social networks, mediators and sexual health outcomes); baseline and follow-up questionnaire (approximately 6 months later) for intervention year group.

Results

A total of 104 students were trained as peer supporters (just over half of those nominated for the role by their peers). Role retention was very high (97%). Of 611 students completing the follow-up questionnaire, 58% reported exposure to STASH study activities. Intervention acceptability was high among students and stakeholders. Activities were delivered with good fidelity. The peer supporters were active, representative of their year group and well connected within their social network. Carefully managed social media use by peer supporters augmented conversations. A primary outcome of ‘always safer sex’ was identified, measured as no sex or always condom use for vaginal or anal sex in the last 6 months. The intervention cost £42 per student. Six progression criteria were met. A seventh criterion (regarding uptake of role by peer supporters) was not.

Limitations

Small feasibility study that cannot comment on effectiveness.

Conclusions

The STASH intervention is feasible and acceptable within the context of Scottish secondary schools. The results support continuation to a full-scale evaluation.

Future work

Small-scale improvements to the intervention, refinement to programme theory and funding sought for full-scale evaluation.

Safetxt: a safer sex intervention delivered by mobile phone messaging on sexually transmitted infections (STI) among young people in the UK - protocol for a randomised controlled trial

INTRODUCTION

Young people aged 16 to 24 have the highest prevalence of genital chlamydia and gonorrhoea compared with other age groups and re-infection rates following treatment are high. Long-term adverse health effects include subfertility and ectopic pregnancy, particularly among those with repeated infections. We developed the safetxt intervention delivered by text message to reduce sexually transmitted infection (STI) by increasing partner notification, condom use and (STI) testing among young people in the UK.

METHODS AND ANALYSIS

A single-blind randomised trial to reliably establish the effect of the safetxt intervention on chlamydia and gonorrhoea infection at 1 year. We will recruit 6250 people aged 16 to 24 years who have recently been diagnosed with chlamydia, gonorrhoea or non-specific urethritis from health services in the UK. Participants will be allocated to receive the safetxt intervention (text messages designed to promote safer sexual health behaviours) or to receive the control text messages (monthly messages asking participants about changes in contact details) by an automated remote online randomisation system. The primary outcome will be the cumulative incidence of chlamydia and gonorrhoea infection at 1 year assessed by nucleic acid amplification tests. Secondary outcomes include partner notification, correct treatment of infection, condom use and STI testing prior to sex with new partners.

ETHICS AND DISSEMINATION

Ethics approval was obtained from NHS Health Research Authority - London - Riverside Research Ethics Committee (REC reference: 15/LO/1665) and the London School of Hygiene & Tropical Medicine. We will submit the results of the trial for publication in peer-reviewed journals.

Factors influencing sexual and reproductive health of Muslim women: a systematic review

BACKGROUND

In Islamic societies, issues related to sexual and reproductive health (SRH) are rarely discussed and considered sensitive subjects. This review aimed to identify any personal, religious, cultural, or structural barriers to SRH service and education among Muslim women worldwide.

METHODS

A search for qualitative and quantitative studies was conducted on seven electronic databases. A narrative synthesis using thematic analysis was conducted.

RESULTS

Fifty-nine studies were included from 22 countries: 19 qualitative, 38 quantitative and two mixed methods. Many Muslim women have poor SRH knowledge, and negative attitudes which influence their access to, and use of SRH services. Barriers to contraception use among Muslim women included a lack of basic reproductive knowledge, insufficient knowledge about contraception, misconceptions, and negative attitudes. Women had negative attitudes towards family planning for limiting the number of children but not for child spacing, which reflected religious views towards family planning. Religious and cultural beliefs were barriers to contraception use and access to SRH services and information. Family and the community have a significant impact on women's contraceptive use and access to SRH services. Husband and family opposition played a significant role in contraception access and use. Fear of stigmatization and being labelled as having pre-marital sexual relations among unmarried women acted as the main barrier to accessing contraception and seeking SRH information and services.

CONCLUSION

The findings reveal that there are multiple levels of factors that influence Muslim women's SRH. Poor SRH knowledge and practices among Muslim women is complex matter that is affected by personal, community, cultural, religious factors and existing policies and regulations. All these factors overlap and are affected by each other. There is an urgent need for interventions addressing modifiable barriers to SRH education and services to improve knowledge, informed choice and access to services to facilitate better sexual and reproductive wellbeing for Muslim women. It is important to note that while this review aimed to report findings on Muslim women, we acknowledge that significant variations exist within every culture and religion.

Concerns about disclosing a high-risk cervical human papillomavirus (HPV) infection to a sexual partner: a systematic review and thematic synthesis

BACKGROUND

Human papillomavirus (HPV)-based cervical screening is now replacing cytology-based screening in several countries and many women in screening programmes will consequently receive HPV-positive results. Because of the sexually transmitted nature of HPV, receiving an HPV-positive result may raise questions about disclosing the infection to a sexual partner.

OBJECTIVE

To review the quantitative and qualitative literature exploring women's concerns about disclosing a high-risk cervical HPV infection to a sexual partner.

METHODS

We searched MEDLINE, PsycINFO, CINAHL Plus, Web of Science and EMBASE for studies reporting at least one disclosure-related outcome among women with high-risk HPV. We also searched the grey literature and carried out forward/backward citation searches. A narrative synthesis for quantitative studies and a thematic synthesis for qualitative studies were conducted.

RESULTS

Thirteen articles met the inclusion criteria (12 qualitative, 1 quantitative). In the quantitative study, 60% of HPV-positive women felt disclosing an HPV result was 'risky'. Concerns about disclosing HPV to a sexual partner were influenced by the stigma that is associated with having an STI and uncertainty about how their partner would respond. Women questioned how, when and to whom they should disclose their HPV-positive status.

CONCLUSIONS

The studies included in this review provide rich information about the range of concerns women have, the reasons for these concerns, and the questions women have about disclosing HPV to sexual partners. As studies were predominantly qualitative, the prevalence of concerns is unclear.

An interactive website for informed contraception choice: randomised evaluation of Contraception Choices

OBJECTIVE

Improving use of effective contraception to prevent unintended pregnancy is a global priority, but misperceptions and concerns about contraception are common. Our objective was to evaluate an interactive website to aid informed choice of contraception.

METHODS

The Contraception Choices website is an interactive digital intervention which offers tailored advice to aid contraception decision-making (www.contraceptionchoices.org). In a parallel single-blind trial, we randomised 927 women aged 15-30 years from six clinic settings to access the intervention website (n = 464) or to a waiting-list control group (n = 463). The study was initially a feasibility trial, evolving into an evaluation of efficacy, with two primary outcomes at six months: long-acting reversible contraception (LARC) use, and satisfaction with contraceptive method. Secondary outcomes included self-reported pregnancy and sexually transmitted infection diagnoses. Free-text comments on the 3 and 6 month outcome surveys were analysed thematically.

FINDINGS

There was no significant difference between intervention and control groups in the proportion of women using LARC [30.4% intervention versus 31.0% control; adjusted odds ratio 0.87 (95% confidence interval 0.60 to 1.28)]; satisfaction with contraceptive method [82.6% versus 82.1%; adjusted ordinal odds ratio 0.93 (95% CI 0.69 to 1.25)]; self-reported pregnancy [3.3% versus 4.1%; adjusted odds ratio 0.90 (95% CI 0.45 to 1.79)] nor sexually transmitted infection [5.3% versus 4.7%; adjusted odds ratio 0.72 (95% CI 0.55 to 2.36)]. Highly positive free-text comments from intervention participants indicated that the website facilitates contraception choice and can help women feel better prepared before consultation with healthcare providers.

INTERPRETATION

The Contraception Choices website was popular for its design, trustworthy information and decision aids but it was not associated with significant differences in use of LARC or satisfaction with contraceptive method. An interactive website can aid contraception choice, but interventions that address factors beyond women's control, such as access to services, and partner, family or community influences are needed to complement this approach.

RESEARCH IN CONTEXT

Preventing unintended pregnancy through effective use of contraception is essential for women's health, but choosing between different contraceptive methods can be challenging, and the opportunity for adequate discussion during routine consultations is often constrained.

EVIDENCE BEFORE THIS STUDY

We conducted two systematic literature reviews: 1) Factors influencing contraception choice, uptake and use: a meta-synthesis of systematic reviews; and 2) Effectiveness of interactive digital interventions (IDI) for contraception choice, uptake and use. For the first review we searched PubMed, CDSR, Epistemonikos, DoPHER, DARE, NHS Economic Evaluation Database, Campbell Library, NIHR Health Technology Assessment, and Health Evidence Canada databases for systematic reviews which addressed contraceptive choice, uptake or use, from 2000 to 2017. PROSPERO registration number: CRD42017081521 https://www.crd.york.ac.uk/PROSPERO/display_record.php?RecordID=81521. We synthesised the findings of 18 systematic reviews of mostly moderate or high quality. They highlighted the importance of women's knowledge, beliefs, perceptions of side effects and health risks, as well as relationship status, social network, economic and healthcare factors on contraception choice and use. For the second review, we searched 23 electronic databases, trials registers and reference lists for randomised controlled trials of IDI for contraception, including CENTRAL, MEDLINE, EMBASE, CINAHL, ERIC, ASSIA and PsycINFO, from start date to June 2017. PROSPERO registration number: CRD42017081636. We found only five randomised trials of IDI, all from the USA. Risk of bias prevented synthesis of results. www.crd.york.ac.uk/PROSPERO/display_record.php?RecordID=81636.

ADDED VALUE OF THIS STUDY

Women's common concerns about contraception - fear of hormones, weight gain, cancer, infertility, mood changes, breaks from contraception and changes in bleeding patterns - underpinned development of a new interactive website (www.contraceptionchoices.org). Contraception Choices addresses women's concerns through succinct text; Q and A format (Frequently Asked Questions, Did you Know?; videos of women and health professionals); an effectiveness infographic, and an interactive decision aid (What's right for me?).In an online randomised trial with 927 women attending clinics, we found no association of the Contraception Choices intervention with the primary outcomes - satisfaction with contraceptive method and uptake of long-acting reversible methods at 6 months. Nor did we find an association with secondary adverse outcomes - sexually transmitted infections or pregnancy. Comments from women indicated that the website can meet young women's need for information on the benefits and drawbacks of contraception, help them to make informed decisions, and feel better prepared before healthcare consultations. Contraception Choices is now available on the NHS website: www.nhs.uk/conditions/contraception/which-method-suits-me.

IMPLICATIONS OF ALL THE AVAILABLE EVIDENCE

Interactive digital interventions (websites) can aid contraception choice, but other intervention research is needed to address wider influences on unintended pregnancy, including partner views, friends, family, the media, wider society and experiences with healthcare professionals. Future research could examine the impact of the website in different settings, e.g. schools or different countries. We hypothesise that use of the website during contraceptive consultations might improve the efficiency or quality of consultation, for both patients and healthcare providers. Appropriate methodology and time-scale for evaluating digital health interventions remains a key question.

The psychosexual impact of testing positive for high-risk cervical human papillomavirus (HPV): A systematic review

Objectives

Many countries are implementing human papillomavirus (HPV)‐based cervical screening due to the higher sensitivity of the test compared with cytology. As HPV is sexually transmitted, there may be psychosexual consequences of testing positive for the virus. We aimed to review the literature exploring the psychosexual impact of testing positive for high‐risk cervical HPV.

Methods

MEDLINE, PsycINFO, CINAHL Plus, Web of Science, and EMBASE were searched with no date limits. We also searched the grey literature, reference lists of included articles and carried out forward citation searching. Eligible studies reported at least one psychosexual outcome among HPV‐positive women. Qualitative and quantitative papers were included. We extracted data using a standardised form and carried out a quality assessment for each article. We conducted a narrative synthesis for quantitative studies and a thematic synthesis for qualitative studies.

Results

Twenty‐five articles were included. Quantitative study designs were diverse making it difficult to determine the impact that an HPV positive result would have in the context of routine screening. The qualitative literature suggested that psychosexual concerns cover a broad range of aspects relating to women's current and past relationships, both interpersonal and sexual.

Conclusions

The psychosexual impact of testing positive for high‐risk cervical HPV is unclear. This review highlights the need for further research in the context of HPV‐based cervical screening. As primary HPV testing is introduced more widely, it is important to understand women's responses to testing HPV positive in the cancer screening context to minimise any adverse psychosexual impact.

JACK trial protocol: a phase III multicentre cluster randomised controlled trial of a school-based relationship and sexuality education intervention focusing on young male perspectives

INTRODUCTION

Teenage pregnancy remains a worldwide health concern which is an outcome of, and contributor to, health inequalities. The need for gender-aware interventions with a focus on males in addressing teenage pregnancy has been highlighted as a global health need by WHO and identified in systematic reviews of (relationship and sexuality education (RSE)). This study aims to test the effectiveness of an interactive film-based RSE intervention, which draws explicit attention to the role of males in preventing an unintended pregnancy by reducing unprotected heterosexual teenage sex among males and females under age 16 years.

METHODS AND ANALYSIS

A phase III cluster randomised trial with embedded process and economic evaluations. If I Were Jack encompasses a culturally sensitive interactive film, classroom materials, a teacher-trainer session and parent animations and will be delivered to replace some of the usual RSE for the target age group in schools in the intervention group. Schools in the control group will not receive the intervention and will continue with usual RSE. Participants will not be blinded to allocation. Schools are the unit of randomisation stratified per country and socioeconomic status. We aim to recruit 66 UK schools (24 in Northern Ireland; 14 in each of England, Scotland and Wales), including approximately 7900 pupils. A questionnaire will be administered at baseline and at 12-14 months postintervention. The primary outcome is reported unprotected sex, a surrogate measure associated with unintended teenage pregnancy. Secondary outcomes include knowledge, attitudes, skills and intentions relating to avoiding teenage pregnancy in addition to frequency of engagement in sexual intercourse, contraception use and diagnosis of sexually transmitted infections.

Abrupt burial imparts persistent changes to the bacterial diversity of turbidite-associated sediment profiles

The emplacement of subaqueous gravity-driven sediment flows imposes a significant physical and geochemical impact on underlying sediment and microbial communities. Although previous studies have established lasting mineralogical and biological signatures of turbidite deposition, the response of bacteria and archaea within and beneath debris flows remains poorly constrained. Both bacterial cells associated with the underlying sediment and those attached to allochthonous material must respond to substantially altered environmental conditions and selective pressures. As a consequence, turbidites and underlying sediments provide an exceptional opportunity to examine (i) the microbial community response to rapid sedimentation and (ii) the preservation and identification of displaced micro-organisms. We collected Illumina MiSeq sequence libraries across turbidite boundaries at ~26 cm sediment depth in La Jolla Canyon off the coast of California, and at ~50 cm depth in meromictic Twin Lake, Hennepin County, MN. 16S rRNA gene signatures of relict and active bacterial populations exhibit persistent differences attributable to turbidite deposition. In particular, both the marine and lacustrine turbidite boundaries are sharply demarcated by the abundance and diversity of Chloroflexi, suggesting a characteristic sensitivity to sediment disturbance history or to differences in organic substrates across turbidite profiles. Variations in the abundance of putative dissimilatory sulfate-reducing Deltaproteobacteria across the buried La Jolla Canyon sediment-water interface reflect turbidite-induced changes to the geochemical environment. Species-level distinctions within the Deltaproteobacteria clearly conform to the sedimentological boundary, suggesting a continuing impact of genetic inheritance distinguishable from broader trends attributable to selective pressure. Abrupt, <1-cm scale changes in bacterial diversity across the Twin Lake turbidite contact are consistent with previous studies showing that relict DNA signatures attributable to sediment transport may be more easily preserved in low-energy, anoxic environments. This work raises the possibility that deep subsurface microbial communities may inherit variations in microbial diversity from sediment flow and deformation events.

The Men's Safer Sex project: intervention development and feasibility randomised controlled trial of an interactive digital intervention to increase condom use in men

BACKGROUND

This report details the development of the Men's Safer Sex website and the results of a feasibility randomised controlled trial (RCT), health economic assessment and qualitative evaluation.

OBJECTIVES

(1) Develop the Men's Safer Sex website to address barriers to condom use; (2) determine the best design for an online RCT; (3) inform the methods for collecting and analysing health economic data; (4) assess the Sexual Quality of Life (SQoL) questionnaire and European Quality of Life-5 Dimensions, three-level version (EQ-5D-3L) to calculate quality-adjusted life-years (QALYs); and (5) explore clinic staff and men's views of online research methodology.

METHODS

(1) Website development: we combined evidence from research literature and the views of experts (n = 18) and male clinic users (n = 43); (2) feasibility RCT: 159 heterosexually active men were recruited from three sexual health clinics and were randomised by computer to the Men's Safer Sex website plus usual care (n = 84) or usual clinic care only (n = 75). Men were invited to complete online questionnaires at 3, 6, 9 and 12 months, and sexually transmitted infection (STI) diagnoses were recorded from clinic notes at 12 months; (3) health economic evaluation: we investigated the impact of using different questionnaires to calculate utilities and QALYs (the EQ-5D-3L and SQoL questionnaire), and compared different methods to collect resource use; and (4) qualitative evaluation: thematic analysis of interviews with 11 male trial participants and nine clinic staff, as well as free-text comments from online outcome questionnaires.

RESULTS

(1) Software errors and clinic Wi-Fi access presented significant challenges. Response rates for online questionnaires were poor but improved with larger vouchers (from 36% with £10 to 50% with £30). Clinical records were located for 94% of participants for STI diagnoses. There were no group differences in condomless sex with female partners [incidence rate ratio (IRR) 1.01, 95% confidence interval (CI) 0.52 to 1.96]. New STI diagnoses were recorded for 8.8% (7/80) of the intervention group and 13.0% (9/69) of the control group (IRR 0.75, 95% CI 0.29 to 1.89). (2) Health-care resource data were more complete using patient files than questionnaires. The probability that the intervention is cost-effective is sensitive to the source of data used and whether or not data on intended pregnancies are included. (3) The pilot RCT fitted well around clinical activities but 37% of the intervention group did not see the Men's Safer Sex website and technical problems were frustrating. Men's views of the Men's Safer Sex website and research procedures were largely positive.

CONCLUSIONS

It would be feasible to conduct a large-scale RCT using clinic STI diagnoses as a primary outcome; however, technical errors and a poor response rate limited the collection of online self-reported outcomes. The next steps are (1) to optimise software for online trials, (2) to find the best ways to integrate digital health promotion with clinical services, (3) to develop more precise methods for collecting resource use data and (4) to work out how to overcome barriers to digital intervention testing and implementation in the NHS.

Experimental precipitation of apatite pseudofossils resembling fossil embryos

Certain phosphatic grains preserved in the rock record are interpreted as microfossils representing a diversity of microorganisms from bacteria to fossil embryos. In addition to bona fide primary biological features, phosphatic microfossils and fossil embryos commonly exhibit features that result from abiotic precipitation or diagenetic alteration. Distinguishing between abiotic and primary biological features can be difficult, and some features thought to represent biological tissue could instead be artifacts that are unrelated to the original morphology of a preserved organism. Here, we present experimentally generated, abiotically produced mineral precipitates that morphologically resemble biologically produced features, some of which may be observed in the rock record or noted in extant organisms, including embryos. These findings extend the diversity of biomorphic features known to result from abiotic precipitation.

Increasing condom use in heterosexual men: development of a theory-based interactive digital intervention

Increasing condom use to prevent sexually transmitted infections is a key public health goal. Interventions are more likely to be effective if they are theory- and evidence-based. The Behaviour Change Wheel (BCW) provides a framework for intervention development. To provide an example of how the BCW was used to develop an intervention to increase condom use in heterosexual men (the MenSS website), the steps of the BCW intervention development process were followed, incorporating evidence from the research literature and views of experts and the target population. Capability (e.g. knowledge) and motivation (e.g. beliefs about pleasure) were identified as important targets of the intervention. We devised ways to address each intervention target, including selecting interactive features and behaviour change techniques. The BCW provides a useful framework for integrating sources of evidence to inform intervention content and deciding which influences on behaviour to target.

Challenges and opportunities in evaluating a digital sexual health intervention in a clinic setting: Staff and patient views

Objectives

The aim of the study was to gather the views of sexual health clinic staff and male clinic users regarding digital sexual health promotion and online trial procedures.

Methods

The Men’s Safer Sex website was offered on tablet computers to men in the waiting rooms of three sexual health clinics, in a feasibility online randomised controlled trial (RCT). Interviews were conducted with 11 men who had participated in the trial and with nine clinic staff, to explore their views of the website and views of the online trial. Interviews were audio-recorded and transcribed, and we conducted a thematic analysis of interviews and of 281 free text comments from the online RCT outcome questionnaires.

Results

Clinic users and staff felt that digital interventions such as the Men’s Safer Sex website are useful, especially if NHS endorsed. Pre-appointment waiting time presents a good opportunity for intervention but clinic users and staff felt that a website should supplement rather than replace face-to-face healthcare. The RCT procedures fitted well around clinical activities, but men did not self-direct to the tablet computers. Staff were more concerned about consent and confidentiality than clinic users, and staff and patients were frustrated by multiple technical problems. The trial outcome questionnaire was thought-provoking and could constitute an intervention in itself. Participants felt that clinics would need to promote a digital intervention and/or offer the site routinely to promote engagement.

Conclusion

Digital interventions could usefully supplement in-person sexual health care, but there are important obstacles in terms of IT access in NHS settings, and in promoting engagement.

Safetxt: a pilot randomised controlled trial of an intervention delivered by mobile phone to increase safer sex behaviours in young people

OBJECTIVE

To test the procedures proposed for a main trial of a safer sex intervention for young people delivered by mobile phone text message ('safetxt').

DESIGN AND SETTING

Pilot randomised controlled trial. Participants were recruited through sexual health services in the UK. An independent online randomisation system allocated participants to receive the safetxt intervention or to receive the control text messages (monthly messages about participation in the study). Texting software delivered the messages in accordance with a predetermined schedule.

PARTICIPANTS

Residents of England aged 16-24 who had received either a positive chlamydia test result or reported unsafe sex in the last year (defined as more than 1 partner and at least 1 occasion of sex without a condom).

INTERVENTION

The safetxt intervention is designed to reduce sexually transmitted infection in young people by supporting them in using condoms, telling a partner about an infection and testing before unprotected sex with a new partner. Safetxt was developed drawing on: behavioural science; face-to-face interventions; the factors known to influence safer sex behaviours and the views of young people.

OUTCOMES

The coprimary outcomes of the pilot trial were the recruitment rate and completeness of follow-up.

RESULTS

We recruited 200 participants within our target of 3 months and we achieved 81% (162/200) follow-up response for the proposed primary outcome of the main trial, cumulative incidence of chlamydia at 12 months.

CONCLUSIONS

Recruitment, randomisation, intervention delivery and follow-up were successful and a randomised controlled trial of the safetxt intervention is feasible.

The Men's Safer Sex Trial: A feasibility randomised controlled trial of an interactive digital intervention to increase condom use in men

Objectives

We aimed to determine the feasibility of an online randomised controlled trial (RCT) of the Men’s Safer Sex website, measuring condom use and sexually transmitted infection (STI).

Methods

For this study 159 men aged ≥16 with female sexual partners and recent condomless sex or suspected STI were recruited from three UK sexual health clinics. Participants were randomised to the intervention website plus usual clinic care (n = 84), or usual clinic care only (n = 75). Online outcome data were solicited at 3, 6, and 12 months.

Results

Men were enrolled via tablet computers in clinic waiting rooms. Software errors and clinic Wi-Fi access presented significant challenges, and online questionnaire response rates were poor (36% at 3 months with a £10 voucher; 50% at 12 months with £30). Clinical records (for STI diagnoses) were located for 94% of participants. Some 37% of the intervention group did not see the intervention website (n = 31/84), and (as expected) there was no detectable difference in condomless sex with female partners (IRR = 1.01, 95% CI 0.52 to 1.96). New acute STI diagnoses were recorded for 8.8% (7/80) of the intervention group, and 13.0% (9/69) of the control group over 12 months (IRR = 0.75, 95% CI 0.29 to 1.90).

Conclusion

It is likely to be feasible to conduct a future large-scale RCT to assess the impact of an online intervention using clinic STI diagnoses as a primary outcome. However, practical and technical challenges need to be addressed before the potential of digital media interventions can be realised in sexual health settings.

Young People's Views and Experiences of a Mobile Phone Texting Intervention to Promote Safer Sex Behavior

BACKGROUND

The risk of poor sexual health, including unplanned pregnancy and sexually transmitted infections (STIs), is greatest amongst young people. Innovative and acceptable interventions to improve sexual health are required. Mobile phone text messaging (short message service, SMS) interventions have the potential to reach large numbers of people at relatively low cost, but greater understanding is needed on how these interventions should be developed and how they work.

OBJECTIVES

The aim of this paper is to explore young people's views of and experiences with a mobile phone text messaging intervention to promote safer sex behavior.

METHODS

We undertook qualitative interviews with young people aged 16 to 24 years as part of a pilot trial of a sexual health intervention delivered by text message in the United Kingdom. Study participants received sexual health promotion text messages based on behavior-change techniques. The message content, tailored by gender and STI status, included support for correct STI treatment and promotion of safer sex behaviors. Young people were eligible if they had received a positive chlamydia test or had more than one partner and at least one episode of unprotected sex in the last year. Telephone interviews were conducted 2 to 3 weeks after initiation of the intervention. A semi-structured topic guide was followed to explore participant experiences and a thematic analysis was conducted.

RESULTS

We conducted 16 telephone interviews with participants who had received the text intervention and an additional four interviews with those in the control group (13 women and 7 men). Intervention participants found text messages easy to understand and appearing to come from a friendly and trustworthy source. They considered the frequency and timing of messages to be appropriate, and delivery via mobile phones convenient. Receipt of support by text message allowed recipients to assimilate information at their own pace, and prompted reflection on and sharing of messages with friends, family members, and partners, thus providing opportunities for education and discussion. For some recipients, the messages had increased their knowledge of how to correctly use condoms. Some described how the messages had increased their confidence and reduced stigma, enabling them to disclose infection to a partner and/or to do so sooner and more calmly. Discussing the messages with a partner reportedly enabled some women to negotiate condom use.

CONCLUSION

From the perspective of the recipients, the tone, frequency, and content of the text messaging-based sexual health intervention was acceptable and appropriate. Their accounts indicated that the intervention increased knowledge, confidence, and safer sex behaviors. A large-scale randomized controlled trial (RCT) is needed to assess effectiveness.

Barite encrustation of benthic sulfur-oxidizing bacteria at a marine cold seep

Crusts and chimneys composed of authigenic barite are found at methane seeps and hydrothermal vents that expel fluids rich in barium. Microbial processes have not previously been associated with barite precipitation in marine cold seep settings. Here, we report on the precipitation of barite on filaments of sulfide-oxidizing bacteria at a brine seep in the Gulf of Mexico. Barite-mineralized bacterial filaments in the interiors of authigenic barite crusts resemble filamentous sulfide-oxidizing bacteria of the genus Beggiatoa. Clone library and iTag amplicon sequencing of the 16S rRNA gene show that the barite crusts that host these filaments also preserve DNA of Candidatus Maribeggiatoa, as well as sulfate-reducing bacteria. Isotopic analyses show that the sulfur and oxygen isotope compositions of barite have lower δ(34)S and δ(18)O values than many other marine barite crusts, which is consistent with barite precipitation in an environment in which sulfide oxidation was occurring. Laboratory experiments employing isolates of sulfide-oxidizing bacteria from Gulf of Mexico seep sediments showed that under low sulfate conditions, such as those encountered in brine fluids, sulfate generated by sulfide-oxidizing bacteria fosters rapid barite precipitation localized on cell biomass, leading to the encrustation of bacteria in a manner reminiscent of our observations of barite-mineralized Beggiatoa in the Gulf of Mexico. The precipitation of barite directly on filaments of sulfide-oxidizing bacteria, and not on other benthic substrates, suggests that sulfide oxidation plays a role in barite formation at certain marine brine seeps where sulfide is oxidized to sulfate in contact with barium-rich fluids, either prior to, or during, the mixing of those fluids with sulfate-containing seawater in the vicinity of the sediment/water interface. As with many other geochemical interfaces that foster mineral precipitation, both biological and abiological processes likely contribute to the precipitation of barite at marine brine seeps such as the one studied here.

Defining the Content of an Online Sexual Health Intervention: The MenSS Website

Background

Health promotion and risk reduction are essential components of sexual health care. However, it can be difficult to prioritize these within busy clinical services. Digital interventions may provide a new method for supporting these.

Objective

The MenSS (Men’s Safer Sex) website is an interactive digital intervention developed by a multidisciplinary team, which aims to improve condom use in men who have sex with women (MSW). This paper describes the content of this intervention, and the rationale for it.

Methods

Content was informed by a literature review regarding men’s barriers to condom use, workshops with experts in sexual health and technology (N=16) and interviews with men in sexual health clinics (N=20). Data from these sources were analyzed thematically, and synthesized using the Behavior Change Wheel framework.

Results

The MenSS intervention is a website optimized for delivery via tablet computer within a clinic waiting room setting. Key targets identified were condom use skills, beliefs about pleasure and knowledge about risk. Content was developed using behavior change techniques, and interactive website features provided feedback tailored for individual users.

Conclusions

This paper provides a detailed description of an evidence-based interactive digital intervention for sexual health, including how behavior change techniques were translated into practice within the design of the MenSS website. Triangulation between a targeted literature review, expert workshops, and interviews with men ensured that a range of potential influences on condom use were captured.

The Men's Safer Sex (MenSS) trial: protocol for a pilot randomised controlled trial of an interactive digital intervention to increase condom use in men

INTRODUCTION

Sexually transmitted infections (STI) are a major public health problem. Condoms provide effective protection but there are many barriers to use. Face-to-face health promotion interventions are resource-intensive and show mixed results. Interactive digital interventions may provide a suitable alternative, allowing private access to personally tailored behaviour change support. We have developed an interactive digital intervention (the Men's Safer Sex (MenSS) website) which aims to increase condom use in men. We describe the protocol for a pilot trial to assess the feasibility of a full-scale randomised controlled trial of the MenSS website in addition to usual sexual health clinical care.

PARTICIPANTS

Men aged 16 or over who report female sexual partners and recent unprotected sex or suspected acute STI. PARTICIPANTS (N=166) will be enrolled using a tablet computer in clinic waiting rooms. All trial procedures will be online, that is, eligibility checks; study consent; trial registration; automated random allocation; and data submission. At baseline and at 3, 6 and 12 months, an online questionnaire will assess condom use, self-reported STI diagnoses, and mediators of condom use (eg, knowledge, intention). Reminders will be by email and mobile phone. The primary outcome is condom use, measured at 3 months. STI rates will be recorded from sexual health clinic medical records at 12 months. The feasibility of a cost-effectiveness analysis will be assessed, to calculate incremental cost per STI prevented (Chlamydia or Gonorrhoea), from the NHS perspective.

ETHICS AND DISSEMINATION

Ethical approval: City and East NHS Research Ethics Committee (reference number 13 LO 1801). Findings will be made available through publication in peer-reviewed journals, and to participants and members of the public via Twitter and from the University College London eHealth Unit website. Raw data will be made available on request.

Horizontal gene transfer and the rock record: comparative genomics of phylogenetically distant bacteria that induce wrinkle structure formation in modern sediments

Wrinkle structures are sedimentary features that are produced primarily through the trapping and binding of siliciclastic sediments by mat-forming micro-organisms. Wrinkle structures and related sedimentary structures in the rock record are commonly interpreted to represent the stabilizing influence of cyanobacteria on sediments because cyanobacteria are known to produce similar textures and structures in modern tidal flat settings. However, other extant bacteria such as filamentous representatives of the family Beggiatoaceae can also interact with sediments to produce sedimentary features that morphologically resemble many of those associated with cyanobacteria-dominated mats. While Beggiatoa spp. and cyanobacteria are metabolically and phylogenetically distant, genomic analyses show that the two groups share hundreds of homologous genes, likely as the result of horizontal gene transfer. The comparative genomics results described here suggest that some horizontally transferred genes may code for phenotypic traits such as filament formation, chemotaxis, and the production of extracellular polymeric substances that potentially underlie the similar biostabilizing influences of these organisms on sediments. We suggest that the ecological utility of certain basic life modes such as the construction of mats and biofilms, coupled with the lateral mobility of genes in the microbial world, introduces an element of uncertainty into the inference of specific phylogenetic origins from gross morphological features preserved in the ancient rock record.

The Sexunzipped trial: young people's views of participating in an online randomized controlled trial

Background

Incidence of sexually transmitted infections (STIs) among young people in the United Kingdom is increasing. The Internet can be a suitable medium for delivery of sexual health information and sexual health promotion, given its high usage among young people, its potential for creating a sense of anonymity, and ease of access. Online randomized controlled trials (RCTs) are increasingly being used to evaluate online interventions, but while there are many advantages to online methodologies, they can be associated with a number of problems, including poor engagement with online interventions, poor trial retention, and concerns about the validity of data collected through self-report online. We conducted an online feasibility trial that tested the effects of the Sexunzipped website for sexual health compared to an information-only website. This study reports on a qualitative evaluation of the trial procedures, describing participants’ experiences and views of the Sexunzipped online trial including methods of recruitment, incentives, methods of contact, and sexual health outcome measurement.

Objective

Our goal was to determine participants’ views of the acceptability and validity of the online trial methodology used in the pilot RCT of the Sexunzipped intervention.

Methods

We used three qualitative data sources to assess the acceptability and validity of the online pilot RCT methodology: (1) individual interviews with 22 participants from the pilot RCT, (2) 133 emails received by the trial coordinator from trial participants, and (3) 217 free-text comments from the baseline and follow-up questionnaires. Interviews were audio-recorded and transcribed verbatim. An iterative, thematic analysis of all three data sources was conducted to identify common themes related to the acceptability and feasibility of the online trial methodology.

Results

Interview participants found the trial design, including online recruitment via Facebook, online registration, email communication with the researchers, and online completion of sexual health questionnaires to be highly acceptable and preferable to traditional methods. Incentives might assist in recruiting those who would not otherwise participate. Participants generally enjoyed taking part in sexual health research online and found the questionnaire itself thought-provoking. Completing the sexual health questionnaires online encouraged honesty in responding that might not be achieved with other methods. The majority of interview participants also thought that receiving and returning a urine sample for chlamydia testing via post was acceptable.

Conclusions

These findings provide strong support for the use of online research methods for sexual health research, emphasizing the importance of careful planning and execution of all trial procedures including recruitment, respondent validation, trial related communication, and methods to maximize follow-up. Our findings suggest that sexual health outcome measurement might encourage reflection on current behavior, sometimes leading to behavior change.

The Sexunzipped trial: optimizing the design of online randomized controlled trials

Background

Sexual health problems such as unwanted pregnancy and sexually transmitted infection are important public health concerns and there is huge potential for health promotion using digital interventions. Evaluations of digital interventions are increasingly conducted online. Trial administration and data collection online offers many advantages, but concerns remain over fraudulent registration to obtain compensation, the quality of self-reported data, and high attrition.

Objective

This study addresses the feasibility of several dimensions of online trial design—recruitment, online consent, participant identity verification, randomization and concealment of allocation, online data collection, data quality, and retention at 3-month follow-up.

Methods

Young people aged 16 to 20 years and resident in the United Kingdom were recruited to the “Sexunzipped” online trial between November 2010 and March 2011 (n=2036). Participants filled in baseline demographic and sexual health questionnaires online and were randomized to the Sexunzipped interactive intervention website or to an information-only control website. Participants were also randomly allocated to a postal request (or no request) for a urine sample for genital chlamydia testing and receipt of a lower (£10/US$16) or higher (£20/US$32) value shopping voucher compensation for 3-month outcome data.

Results

The majority of the 2006 valid participants (90.98%, 1825/2006) were aged between 18 and 20 years at enrolment, from all four countries in the United Kingdom. Most were white (89.98%, 1805/2006), most were in school or training (77.48%, 1545/1994), and 62.81% (1260/2006) of the sample were female. In total, 3.88% (79/2036) of registrations appeared to be invalid and another 4.00% (81/2006) of participants gave inconsistent responses within the questionnaire. The higher value compensation (£20/US$32) increased response rates by 6-10%, boosting retention at 3 months to 77.2% (166/215) for submission of online self-reported sexual health outcomes and 47.4% (118/249) for return of chlamydia urine samples by post.

Conclusions

It was quick and efficient to recruit young people to this online trial. Our procedures for obtaining online consent, verifying participant identity, automated randomization, and concealment of allocation worked well. The optimal response rate for the online sexual health outcome measurement was comparable to face-to-face trials. Multiple methods of participant contact, requesting online data only, and higher value compensation increased trial retention at 3-month follow-up.

Filamentous sulfur bacteria preserved in modern and ancient phosphatic sediments: implications for the role of oxygen and bacteria in phosphogenesis

Marine phosphate-rich sedimentary deposits (phosphorites) are important geological reservoirs for the biologically essential nutrient phosphorous. Phosphorites first appear in abundance approximately 600 million years ago, but their proliferation at that time is poorly understood. Recent marine phosphorites spatially correlate with the habitats of vacuolated sulfide-oxidizing bacteria that store polyphosphates under oxic conditions to be utilized under sulfidic conditions. Hydrolysis of the stored polyphosphate results in the rapid precipitation of the phosphate-rich mineral apatite-providing a mechanism to explain the association between modern phosphorites and these bacteria. Whether sulfur bacteria were important to the formation of ancient phosphorites has been unresolved. Here, we present the remains of modern sulfide-oxidizing bacteria that are partially encrusted in apatite, providing evidence that bacterially mediated phosphogenesis can rapidly permineralize sulfide-oxidizing bacteria and perhaps other types of organic remains. We also describe filamentous microfossils that resemble modern sulfide-oxidizing bacteria from two major phosphogenic episodes in the geologic record. These microfossils contain sulfur-rich inclusions that may represent relict sulfur globules, a diagnostic feature of modern sulfide-oxidizing bacteria. These findings suggest that sulfur bacteria, which are known to mediate the precipitation of apatite in modern sediments, were also present in certain phosphogenic settings for at least the last 600 million years. If polyphosphate-utilizing sulfide-oxidizing bacteria also played a role in the formation of ancient phosphorites, their requirements for oxygen, or oxygen-requiring metabolites such as nitrate, might explain the temporal correlation between the first appearance of globally distributed marine phosphorites and increasing oxygenation of Neoproterozoic oceans.

Computer-based interventions for sexual health promotion: systematic review and meta-analyses

This systematic review was conducted to determine the effects of self-help interactive computer-based interventions (ICBIs) for sexual health promotion. We searched 40 databases for randomized controlled trials (RCTs) of computer-based interventions, defining 'interactive' as programmes that require contributions from users to produce personally relevant material. We conducted searches and analysed data using Cochrane Collaboration methods. Results of RCTs were pooled using a random-effects model with standardized mean differences for continuous outcomes and odds ratios (ORs) for binary outcomes, with heterogeneity assessed using the I(2) statistic. We identified 15 RCTs of ICBIs (3917 participants). Comparing ICBIs to minimal interventions, there were significant effects on sexual health knowledge (standardized mean difference [SMD] 0.72, 95% confidence interval [CI] 0.27-1.18); safer sex self-efficacy (SMD 0.17, 95% CI 0.05-0.29); safer-sex intentions (SMD 0.16, 95% CI 0.02-0.30); and sexual behaviour (OR 1.75, 95% CI 1.18-2.59). ICBIs had a greater impact on sexual health knowledge than face-to-face interventions did (SMD 0.36, 95% CI 0.13-0.58). ICBIs are effective tools for learning about sexual health, and show promising effects on self-efficacy, intention and sexual behaviour. More data are needed to analyse biological outcomes and cost-effectiveness.

Integrating psychological theory into the design of an online intervention for sexual health: the sexunzipped website

Background

The Internet can provide a confidential and convenient medium for sexual health promotion for young people.

Objective

This paper describes the development of an interactive, theory-based website (Sexunzipped) aimed at increasing safe sexual behavior of young people, as well as an outline of the evaluation protocol.

Methods

The website focuses on safer sex, relationships, and sexual pleasure. An overview of the site is provided, including a description of the theoretical constructs which form the basis of the site development. An integrated behavioral model was chosen as the guiding theory for the Sexunzipped intervention. A randomized trial design will be used to evaluate the site quantitatively.

Results

The content of the site is described in detail with examples of the main content types: information pages, quizzes, and decision-making activities. We describe the protocol for quantitative evaluation of the website using a randomized trial design and discuss the principal challenges involved in developing the site, including the challenge of balancing the requirements of theory with young people’s views on website content and design.

Conclusions

Considerations for future interventions are discussed. Developing an online behavior-change intervention is costly and time consuming. Given the large public health potential, the cost involved in developing online interventions, and the need for attractive design, future interventions may benefit from collaborating with established sites that already have a user base, a brand, and a strong Internet presence. It is vital to involve users in decisions about intervention content, design, and features, paying attention to aspects that will attract and retain users’ interest. A central challenge in developing effective Internet-based interventions for young people is to find effective ways to operationalize theory in ways that address the views and perspectives of young people.

What young people want from a sexual health website: design and development of Sexunzipped

Background

Sexual health education in the United Kingdom is of variable quality, typically focusing on the biological aspects of sex rather than on communication, relationships, and sexual pleasure. The Internet offers a unique opportunity to provide sexual health education to young people, since they can be difficult to engage but frequently use the Internet as a health information resource.

Objectives

To explore through qualitative research young people’s views on what elements of a sexual health website would be appealing and engaging, and their views on the content, design, and interactive features of the Sexunzipped intervention website.

Methods

We recruited 67 young people aged 16–22 years in London, UK. We held 21 focus groups and 6 one-to-one interviews to establish sexual health priorities, views on website look and feel, and what features of a sexual heath website would attract and engage them. Two researchers facilitated the focus groups, using a semistructured topic guide to lead the discussions and asking open questions to elicit a range of views. The discussions and interviews were audio recorded and detailed notes were made on key topics from the audio recording. Young people’s views influenced design templates for the content and interactive features of Sexunzipped.

Results

Young people particularly wanted straightforward information on sexual pleasure, sexually transmitted infections and pregnancy, how to communicate with partners, how to develop skills in giving pleasure, and emotions involved in sex and relationships. Focus group participants wanted social interaction with other young people online and wanted to see themselves reflected in some way such as through images or videos.
