A systematic review of randomised controlled trials of interventions promoting effective condom use

20 years of herpes simplex virus type 2 (HSV-2) research in low-income and middle-income countries: systematic evaluation of progress made in addressing WHO priorities for research in HSV-2/HIV interactions, HSV-2 control and mathematical modelling

INTRODUCTION

Reviewing and updating research priorities is essential to assess progress and to ensure optimal allocation of financial and human resources in research. In 2001, WHO held a research priority setting workshop for herpes simplex virus type 2 (HSV-2) research in low-income and middle-income countries (LMICs). This study aimed to describe progress between 2000 and 2020 in three of the five key research priority areas outlined in the workshop: HSV-2/HIV interactions, HSV-2 control measures and HSV-2 mathematical modelling. The remaining priorities are addressed in a companion paper.

METHOD

A systematic literature search of MEDLINE, CINAHL, Global Health and Cochrane databases was carried out. Relevant primary research studies based in LMICs, written in English and published on 2000-2020 were included. Papers were screened by two independent reviewers, and suitable variables were selected for manual extraction from study texts. Data were organised into an Excel spreadsheet and analysed using IBM SPSS.

RESULTS

In total, 3214 discrete papers were identified, of which 180 were eligible for inclusion (HSV-2/HIV interactions, 98; control measures, 58; mathematical modelling, 24). Most studies were conducted in East Africa. The majority of the 2001 WHO HSV-2 research priorities were addressed at least in part. Overall, despite several studies describing a strong relationship between HSV-2 and the acquisition and transmission of HIV, HSV-2 control repeatedly demonstrated little effect on HIV shedding or transmission. Further, although mathematical modelling predicted that vaccines could significantly impact HSV-2 indicators, HSV-2 vaccine studies were few. Studies of antiviral resistance were also few.

CONCLUSION

Since 2000, LMIC HSV-2 research addressing its control, HIV interactions and mathematical modelling has largely addressed the priorities set in the 2001 WHO HSV-2 workshop. However, key knowledge gaps remain in vaccine research, antiviral cost-effectiveness, antiviral resistance and specific geographical areas.

Interventions Promoting Condom Use Among Youth: A Systematic Review

In many European and other high-income, Western countries, condom use has been decreasing among youth. A variety of promotional strategies to increase condom use exists. Our systematic review aimed to identify effective elements in interventions aimed at increasing condom use in youth. We searched databases (2010-2021) for intervention studies promoting condom use among youth in Western, high-income countries. The primary outcome was condom use; the secondary outcome was sexually transmitted infection (STI) diagnoses. Effectiveness per intervention was defined based on the percentage of comparisons that showed significant increases in condom use and significant decreases in STIs. We compared the effectiveness of interventions for different participant-, intervention- and methodological characteristics. We included 74 papers describing 85 interventions in the review. Overall, the median intervention effectiveness was 33.3% (interquartile range = 0%-66.7%) for condom use and 0% (interquartile range = 0%-100%) for STI diagnoses. Intervention effectiveness for condom use was significantly higher in interventions tailored towards females and males specifically, compared with interventions applied to both sexes combined. Our findings show the difficulty in designing effective interventions to increase condom use among youth. Interventions aimed at either females or males were more effective in increasing condom use.

A qualitative study exploring experiences of the safetxt digital health intervention to reduce sexually transmitted infections in young people in the UK

OBJECTIVES

People aged 16-24 are more likely than other age groups to acquire sexually transmitted infections (STI). Safetxt was a randomised controlled trial of a theory-based digital health intervention to reduce STIs among 16-24 year-old people in the UK. We report results of qualitative research regarding participants' perceptions and experiences of the intervention and trial participation.

DESIGN

Qualitative thematic analysis following a critical realist paradigm of written open feedback comments provided in the 12-month follow-up questionnaire and semistructured interviews.

SETTING

Safetxt trial participants were recruited from UK sexual health clinics.

PARTICIPANTS

Trial inclusion criteria: people aged 16-24 diagnosed with or treated for chlamydia, gonorrhoea or non-specific urethritis. Optional open feedback provided by 3526 of 6248 safetxt participants at 12 months and interviews with a purposive sample of 18 participants after the trial.

RESULTS

We summarise and report results in seven broad themes. According to recipients, the safetxt intervention increased awareness of the importance of avoiding STIs and ways to prevent them. Participants reported improved confidence, agency, sexual well-being and communication about sexual health with partners, friends and family. Recipients attributed increased condom use, increased STI testing after (rather than before) sex with new partners, and more confident partner notification to the intervention. Recipients described a reduced sense of isolation and stigma in having an STI. Control group participants reported that having had an STI and receiving control texts asking them to report any changes in contact details acted as reminders to use condoms and get tested. We also summarise participant recommendations for future interventions and studies.

CONCLUSIONS

While control group participants reported precautionary behaviours were 'triggered' by trial participation, intervention recipients reported additional benefits of the intervention in increasing precautionary behaviours and in broader aspects of sexual health such as confidence, communication, emotional well-being and agency.

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.

Why do men who have sex with men practice condomless sex? A systematic review and meta-synthesis

Background

Despite a large amount of behavioral interventions to reduce human immunodeficiency virus (HIV)-related high-risk sexual behaviors, consistent condom use remains suboptimal among men who have sex with men (MSM). However, current databases are lack of synthesized evidence to explain why MSM practiced condomless sex.

Objective

Our study aims to conduct a systematic review and meta-synthesis of 39 eligible qualitative studies to explore the barriers to condom use among MSM.

Methods

A systematic review and meta-synthesis of qualitative studies (1994–2021). On March 4, 2021, a comprehensive search was conducted in 14 electronic databases. The study was conducted based on the Joanna Briggs Institute’s recommendations.

Results

Thematic analysis produced six synthesized themes, which were classified into three levels according to the Social-ecology Model. Individual level barriers to condom use included physical discomfort, lack of HIV/STI-related knowledge and substance use; interpersonal-level barrier was mainly the condom stigma, namely regarding using condom as symbols of distrust or HIV/sexually transmitted infections (STIs) prevention, or as violating traditional cognition of sex, or as an embarrassing topic; environmental/structural-level barriers included situational unavailability, unaffordability of condoms and power imbalance in the sexual relationship.

Conclusion

This meta-synthesis offered in-depth understanding of condom use barriers for MSM and could guide the development of multifactorial interventions according to the identified barriers, especially targeting to reduce condom stigma, which has not been focused and intervened previously.

The Mediation Effect of Attitudes for the Association between Thoughts and the Use of Condoms in a Mobile-App Environment: From Thought to Intention

The ubiquity of mobile devices and access to the internet has changed our daily life and, in some cases, promoted and facilitated social and sexual interrelationships. There are many applications of technology and campaigns promoting healthy behaviors and prevention of sexually transmitted infections. Can we develop a strategy for the same purpose using mobile devices, based on the theory of attitude change? We developed an app and tested it with 105 undergraduate students, where they had to actively think in favor of condom use with a high amount of elaboration, leading to attitudes and behavioral intention (BI) in concordance with contemporary theories about attitudes and behavioral change. PROCESS macro models were used to analyze potential mediations. Results show a significant correlation between thoughts and attitudes, and attitudes partially mediated the association between thoughts and condom use. Individuals with positive thoughts tended to positively correlate their thoughts with their attitudes, and, consequently, these attitudes with their BI. In this study, we showed that (1) it was possible to develop and test an app based on the elaboration likelihood model (ELM); (2) consistent with previous studies, attitudes partially mediated the association between thoughts and condom use (BI) in a mobile environment; and (3) applications of this strategy can be used to build new approaches for prevention in health care.

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.

Determinants of consistent condom use among Filipino women: Results from the 2017 Philippine National Demographic and Health Survey

BACKGROUND

Consistent condom use in women, defined as the self-reported usage of male condom in every sexual encounter of the respondent with her most recent partner in the last 12 months, had been perennially low in the Philippines. This is despite consistent condom use being a tested and proven public health intervention to prevent unwanted pregnancy and sexually transmitted infections. Considering the high fertility rate, teenage pregnancy rate, and the rapidly increasing incidence of HIV in the country, we identified the determinants of consistent condom use in the Philippines.

METHODS

We used data from the individual recode of the 2017 Philippine National Demographic and Health Survey. We used logistic regression for survey data to identify factors associated with consistent condom use.

RESULTS

Out of 25,074 respondents, only 261 (1.13%) have used condoms consistently with their most recent partner. Reach of information and education campaigns on contraceptive use via different media ranged from 62% via television to 7% via short messaging service. After adjusting for confounders, those who were able to ask their partners to use condoms during sexual intercourse have 6.18 times (adjusted odds ratio (aOR): 6.18; 95% Confidence Interval (95% CI): 2.02. 18.94) greater odds of consistent condom use than those who were unable to ask their partners to use condoms during sexual intercourse. Meanwhile, HIV knowledge (aOR: 1.16; 95% CI: 0.98, 1.38) and hearing about contraception in television (aOR: 1.54; 95% CI: 1.00, 2.38) have weaker associations with consistent condom use.

CONCLUSIONS

The low percentage of those who use condoms consistently, together with the low reach of information and education campaigns, highlight the need to implement multi-faceted and context-specific interventions to promote sexual agency and/or consistent condom use to address the burden of unwanted pregnancies and HIV in the Philippines.

Perception of Peer Condom Use Buffers the Associations Between HIV Knowledge, Self-efficacy, and Condom-Use Intention Among Adolescents: a Moderated Mediation Model

A better understanding of the complex relationships between HIV knowledge, self-efficacy, perception of peer condom use, and condom-use intention is needed for improving HIV prevention among adolescents. The study analyzed survey data collected from high school students (N = 1970) in the Bahamas. Mediation and moderated mediation modeling analyses were used for data analysis. Results showed that self-efficacy mediated the association between HIV knowledge and condom-use intention. Perception of peer condom use moderated the mediation model by modifying the HIV knowledge-self-efficacy and self-efficacy-condom-use intention associations among males, but not for females. Findings of the study suggest the significant impact of perception of peer condom use in competition with HIV knowledge and self-efficacy in promoting condom use. Effective intervention program may consider targeting the modification of adolescents' perception of peer condom use to promote condom use among adolescents.

Using video games to improve the sexual health of young people aged 15-25 years: A rapid review (Preprint)

Background

Sexually transmitted infections and unintended pregnancies among young people remain public health concerns in many countries. To date, interventions that address these concerns have had limited success. Serious games are increasingly being used as educational tools in health and professional public education. Although acknowledged as having great potential, few studies have evaluated the use of serious games in sexual health education among young people, and to date, there have been no published reviews of these studies.

Objective

This study aims to assess the effects of video game–based sexual health interventions for risky sexual behavior in young people aged between 15 and 25 years.

Methods

A rapid review of randomized controlled trials and quasi–randomized controlled trials was performed. The search included the following bibliographic databases: Cochrane Central Register of Controlled Trials, Embase, MEDLINE, PsycINFO, and Scopus. A total of 2 reviewers independently screened 50% (35/70) of the retrieved articles during the full-text screening phase.

Results

From a total of 459 identified citations, after removing duplicates, 327 (71.2%) articles were deemed eligible for title and abstract screening. Of the 327 articles, 70 (21.4%) full texts were screened, from which 10 (3.1%) articles (evaluating 11 different games) were included in the review. The findings highlighted the considerable diversity in video game–based interventions and assessed sexual health outcomes. Although there were some promising findings in outcome studies using game-based interventions, the results across studies were mixed.

Conclusions

Although game interventions for sexual health have been in existence for almost three decades, relatively few studies have evaluated them, and the results of previous outcome studies have been mixed. Moreover, there is little clarity regarding which specific elements of a game facilitate positive outcomes. We provide recommendations for future researchers developing video game–based interventions to improve sexual health in young people.

Feasibility study of the Home-based Exercises for Responsible Sex (HERS) intervention to promote correct and consistent condom use among young women

Background

Male condoms are effective in preventing common sexually transmitted infections (STIs) and unintended pregnancy, if used correctly and consistently. However, condom use errors and problems are common and young people report negative experiences, such as reduced pleasure. The Kinsey Institute Home-Based Exercises for Responsible Sex (KIHERS) is a novel condom promotion intervention for young women, which aims to reduce condom errors and problems, increase self-efficacy and improve attitudes towards condoms, using a pleasure-focussed approach. The study objective was to test the operability, viability and acceptability of an adapted version of the KIHERS intervention with young women aged 16–25 years in the United Kingdom (UK) (Home-Based Exercises for Responsible Sex-UK (HERS-UK).

Methods

A repeated-measures single-arm design was used, with a baseline (T1) and two follow-up assessments (T2 and T3), conducted 4 weeks and 8 weeks post intervention over a 3-month period. Participants were provided a condom kit containing different condoms and lubricants and were asked to experiment with condoms alone using a dildo and/or with a sexual partner. Ten process evaluation interviews were conducted post intervention.

Results

Fifty-five young women received the intervention; 36 (65%) completed T2 and 33 (60%) completed T3. Condom use errors and problems decreased, self-efficacy increased and attitudes towards condoms improved significantly. The proportion of participants who reported using a condom for intercourse in the past 4 weeks increased from T1 (20; 47%) to T2 (27; 87%) and T3 (23; 77%) and using lubricant with a condom for intercourse increased from T1 (6; 30%) to T2 (13; 48%)) and T3 (16; 70%). However, motivation to use condoms did not change. Cronbach’s alpha scores indicated good internal consistency of measures used. Qualitative data provided strong evidence for the acceptability of the intervention.

Conclusions

HERS-UK was implemented as intended and the recruitment strategy was successful within a college/university setting. This feasibility study provided an early indication of the potential effectiveness and acceptability of the intervention, and the benefits of using a pleasure-focussed approach with young women. Measures used captured change in outcome variables and were deemed fit for purpose. Future research should explore cost-effectiveness of this intervention, in a large-scale controlled trial using a diverse sample and targeting young women most at risk of STIs.

Condom application skills and self-efficacy in youth: A systematic review and meta-analysis

Globally, and in the United States (U.S.) specifically, rates of reported sexually transmitted infections (STIs) have been steadily increasing and are especially high among youth aged 13-25 years. Using condoms correctly and consistently is an effective STI prevention measure for sexually active youth, yet public health endeavors tend to focus only on condom use consistency. Directly measuring condom application is challenging and expensive. Alternative tools evaluate this behaviour, but little evidence exists on the appropriateness of these instruments in measuring application skills. This systematic review and meta-analysis examined the association between condom application skills and self-efficacy. We conducted a search of several databases as well as unpublished works. Studies were included if they were in English, examined youth aged 13-25 years, and were available between 1992 and 2019. The authors screened 630 titles and abstracts for initial inclusion criteria. A full-text review of 30 studies was conducted. The authors included 19 studies in the systematic review and 5 studies were included in the meta-analysis. Both a fixed- and random-effects model (Q = .2321, I2 = 0%) yielded a medium-sized statistically non-significant association (r = 0.217) between skills and self-efficacy. Despite the small sample size, findings suggest that skills and self-efficacy may not be as interchangeable as previously assumed when assessing condom application. Implications for future research are discussed.

Sexual health interventions delivered to participants by mobile technology: a systematic review and meta-analysis of randomised controlled trials

BACKGROUND

The use of mobile technologies to prevent STIs is recognised as a promising approach worldwide; however, evidence has been inconclusive, and the field has developed rapidly. With about 1 million new STIs a day globally, up-to-date evidence is urgently needed.

OBJECTIVE

To assess the effectiveness of mobile health interventions delivered to participants for preventing STIs and promoting preventive behaviour.

METHODS

We searched seven databases and reference lists of 49 related reviews (January 1990-February 2020) and contacted experts in the field. We included randomised controlled trials of mobile interventions delivered to adolescents and adults to prevent sexual transmission of STIs. We conducted meta-analyses and assessed risk of bias and certainty of evidence following Cochrane guidance.

RESULTS

After double screening 6683 records, we included 22 trials into the systematic review and 20 into meta-analyses; 18 trials used text messages, 3 used smartphone applications and 1 used Facebook messages as delivery modes. The certainty of evidence regarding intervention effects on STI/HIV occurrence and adverse events was low or very low. There was moderate certainty of evidence that in the short/medium-term text messaging interventions had little or no effect on condom use (standardised mean differences (SMD) 0.02, 95% CI -0.09 to 0.14, nine trials), but increased STI/HIV testing (OR 1.83, 95% CI 1.41 to 2.36, seven trials), although not if the standard-of-care control already contained an active text messaging component (OR 1.00, 95% CI 0.68 to 1.47, two trials). Smartphone application messages also increased STI/HIV testing (risk ratio 1.40, 95% CI 1.22 to 1.60, subgroup analysis, two trials). The effects on other outcomes or of social media or blended interventions is uncertain due to low or very low certainty evidence.

CONCLUSIONS

Text messaging interventions probably increase STI/HIV testing but not condom use in the short/medium term. Ongoing trials will report the effects on biological and other outcomes.

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.

The evaluation of the Woman's Condom marketing approach: What value did peer-led interpersonal communication add to the promotion of a new female condom in urban Lusaka?

During a mass media campaign accompanying the launch of the Maximum Diva Woman's Condom (WC) in Lusaka, Zambia, a cluster-randomized evaluation was implemented to measure the added impact of a peer-led interpersonal communication (IPC) intervention on the awareness and uptake of the new female condom (FC). The WC and mass media campaign were introduced simultaneously in 40 urban wards in April 2016; half of the wards were randomly assigned to the treatment (IPC intervention) with cross-sectional surveys conducted before (n = 2,364) and one year after (n = 2,430) the start of the intervention. A pre-specified intention-to-treat (ITT) analysis measured the impact of randomization to IPC at the community level. In adjusted ITT models, there were no statistically significant differences between intervention and control groups. Due to significant implementation challenges, we also conducted exploratory secondary analyses to estimate effects among those who attended an IPC event (n = 66) using instrumental variable and inverse probability weighting analyses. In addition to increases in FC identification (IPC attendees had higher reported use of any condom, improved perceptions of FC's, and were more likely to have discussed contraceptive use with their partner as compared to non-attendees). The introduction of a new FC product combined with an IPC intervention significantly increased general knowledge and awareness in the community as compared to media alone, but did not lead to detectable community level impacts on other primary outcomes of interest. Observational evidence from our study suggests that IPC attendance is associated with increased use and negotiation. Future studies should explore the intensity and duration of IPC programming necessary to achieve detectable community level impacts on behavior. Trial Registration: AEARCTR-0000899.

Evidence for behavioural interventions addressing condom use fit and feel issues to improve condom use: a systematic review

Continuing high rates of sexually transmissible infections (STIs) in many countries highlight the need to identify effective behavioural interventions. Consistent and correct use of male condoms is a key strategy for the prevention of STIs. However, some men report problems with condom fit (e.g. the size and shape of the condom) and feel (e.g. tightness, irritation, sensitivity), which inhibits their use. We conducted a systematic review to identify existing interventions addressing condom use fit and feel problems. We searched electronic databases for peer-reviewed articles and searched reference lists of retrieved studies. Five studies met the inclusion criteria. These were generally small-scale pilot studies evaluating behavioural interventions to promote safer sex with men aged under 30 years, addressing, among other things, barriers to condom use relating to fit and feel. There were significant increases in the reported use of condoms, including condom use with no errors and problems. Improvements in some condom use mediators were reported, such as condom use self-efficacy, knowledge, intentions and condom use experience. There were mixed findings in terms of the ability of interventions to reduce STI acquisition. Behavioural interventions addressing condom fit and feel are promising in terms of effectiveness but require further evaluation.

What predicts self-efficacy? Understanding the role of sociodemographic, behavioural and parental factors on condom use self-efficacy among university students in Nigeria

BACKGROUND

Risky sexual behaviours are not uncommon among young adults particularly those in the higher levels of education. It is known that higher self-efficacy could contribute to better sexual and reproductive health outcomes including the use of condoms. However, there is limited research on the role of socio-demographic, behavioural and parental factors as predictors of condom-use self-efficacy. As a result, this exploratory study was designed to assess the predictors of self-efficacy for condom use among university students in Nigeria.

METHODS

A cross-sectional survey was conducted with 755 university students in Nigeria from February to April 2018. Self-efficacy for condom use was assessed by combining responses to 11-items measures of condom self-efficacy drawn from the work of Barkley and colleagues. We fitted a structural equation model to identify the pathways through which socio-demographic, behavioural and parental factors predict two constructs of condom-use self-efficacy (self-efficacy for condom purchase and use and partner communication self-efficacy) in the sample.

RESULTS

Demographic factors such as age (β = -0.29, p<0.05) and sex (β = 0.42, p<0.05), as well as ratings on religious importance (β = -0.08, p<0.05) were directly associated with self-efficacy for condom purchase and use. These factors showed significantly mediated effects through sexual experience which also had a direct positive relationship (β = 0.73, p<0.05) with self-efficacy for condom purchase and use. The receipt of parental support, on the other hand, was directly associated with higher partner communication efficacy for condom use (β = 0.07, p<0.05). We found no evidence that the level of partner communication efficacy was directly associated with any of the behavioural, demographic or parental factors.

CONCLUSION

The findings of this study affirm that sex, or age or having higher ratings on religious importance alone does not increases self-efficacy but also exposure to sexual activity through which these factors affect self-efficacy for condom purchase and use. These findings also highlight the need to address and strengthen condom use self-efficacy among young adults, particularly the sexually inexperienced, highly religious and young adults with limited support from their parent.

Sexual risk reduction interventions for patients attending sexual health clinics: a mixed-methods feasibility study

BACKGROUND

Sexually transmitted infections (STIs) continue to represent a major public health challenge. There is evidence that behavioural interventions to reduce risky sexual behaviours can reduce STI rates in patients attending sexual health (SH) services. However, it is not known if these interventions are effective when implemented at scale in SH settings in England.

OBJECTIVES

The study (Santé) had two main objectives - (1) to develop and pilot a package of evidence-based sexual risk reduction interventions that can be delivered through SH services and (2) to assess the feasibility of conducting a randomised controlled trial (RCT) to determine effectiveness against usual care.

DESIGN

The project was a multistage, mixed-methods study, with developmental and pilot RCT phases. Preparatory work included a systematic review, an analysis of national surveillance data, the development of a triage algorithm, and interviews and surveys with SH staff and patients to identify, select and adapt interventions. A pilot cluster RCT was planned for eight SH clinics; the intervention would be offered in four clinics, with qualitative and process evaluation to assess feasibility and acceptability. Four clinics acted as controls; in all clinics, participants would be consented to a 6-week follow-up STI screen.

SETTING

SH clinics in England.

PARTICIPANTS

Young people (aged 16-25 years), and men who have sex with men.

INTERVENTION

A three-part intervention package - (1) a triage tool to score patients as being at high or low risk of STI using routine data, (2) a study-designed web page with tailored SH information for all patients, regardless of risk and (3) a brief one-to-one session based on motivational interviewing for high-risk patients.

MAIN OUTCOME MEASURES

The three outcomes were (1) the acceptability of the intervention to patients and SH providers, (2) the feasibility of delivering the interventions within existing resources and (3) the feasibility of obtaining follow-up data on STI diagnoses (primary outcome in a full trial).

RESULTS

We identified 33 relevant trials from the systematic review, including videos, peer support, digital and brief one-to-one sessions. Patients and SH providers showed preferences for one-to-one and digital interventions, and providers indicated that these intervention types could feasibly be implemented in their settings. There were no appropriate digital interventions that could be adapted in time for the pilot; therefore, we created a placeholder for the purposes of the pilot. The intervention package was piloted in two SH settings, rather than the planned four. Several barriers were found to intervention implementation, including a lack of trained staff time and clinic space. The intervention package was theoretically acceptable, but we observed poor engagement. We recruited patients from six clinics for the follow-up, rather than eight. The completion rate for follow-up was lower than anticipated (16% vs. 46%).

LIMITATIONS

Fewer clinics were included in the pilot than planned, limiting the ability to make strong conclusions on the feasibility of the RCT.

CONCLUSION

We were unable to conclude whether or not a definitive RCT would be feasible because of challenges in implementation of a pilot, but have laid the groundwork for future research in the area.

Inferring individual sexual action dispositions from egocentric network data on dyadic sexual outcomes

In this paper we present a family of models that allows us to estimate egos' unobserved action dispositions from a joint behavioural outcome of a dyadic social interaction process of both egos' and alters' action dispositions. The method is put to test on a data set containing two different types of dyadic activities of high relevance for the spread of sexually transmitted infections (STI), condom use and anal sex. The data consists of individuals older than 15 years old who visited one of the nine youth clinics in the Vastra Gotaland region of Sweden between February 2010 and March 2011 for STI testing. This is hence a group of special interest for STI interventions. We cannot find any difference in condom disposition between women and men. Condoms are initially used more often in less risky types of relationships, especially if the partner ends up as a main partner. When studying the disposition towards anal sex we do however find a difference between men and women. Women are more against practising anal sex than men while the majority of men are neutral towards anal sex.

Recommendations for the Appropriate Structure, Communication, and Investigation of Tobacco Harm Reduction Claims. An Official American Thoracic Society Policy Statement

RATIONALE

The tobacco harm reduction literature is replete with vague language, far-reaching claims, and unwarranted certainty. The American Thoracic Society has increasingly recognized the need for a framework for reliably making such claims. Evidence-based standards improving the scientific value and transparency of harm reduction claims are expected to improve their trustworthiness, clarity, and consistency.

METHODS

Experts from relevant American Thoracic Society committees identified key topic areas for discussion. Literature search strategy included English language articles across Medline, Google Scholar, and the Cochrane Collaborative databases, with expanded search terms including tobacco, addiction, smoking, cigarettes, nicotine, and harm reduction. Workgroup members synthesized their evidentiary summaries into a list of candidate topics suitable for inclusion in the final report. Breakout groups developed detailed content maps of each topic area, including points to be considered for suggested recommendations. Successive draft recommendations were modified using an iterative consensus process until unanimous approval was achieved. Patient representatives ensured the document's relevance to the lay public.

RESULTS

Fifteen recommendations were identified, organized into four framework elements dealing with: estimating harm reduction among individuals, making claims on the basis of population impact, appropriately careful use of language, and ethical considerations in harm reduction.

DISCUSSION

This statement clarifies important principles guiding valid direct and inferential harm reduction claims. Ideals for effective communication with the lay public and attention to unique ethical concerns are also delineated. The authors call for formal systems of grading harm reduction evidence and regulatory assurances of longitudinal surveillance systems to document the impact of harm reduction policies.

Sexual health prevention for incarcerated women: eroticising safe sex during re-entry to the community

INTRODUCTION

In the USA, incarcerated women are disproportionately affected by sexually transmitted infections (STIs) including HIV. Transitioning from incarceration into the community is accompanied by elevated risk behaviours related to acquisition of STIs, yet few efficacious interventions address sexual health prevention among incarcerated women.

METHODS

We conducted an exploratory qualitative study with 21 incarcerated women at four women's state prison facilities in two Northeastern states in the USA. Qualitative data were gathered from four focus groups to guide future intervention development. Focus group discussions were guided by a semi-structured protocol exploring perceptions of sexual health prevention methods, experience with implementing prevention technologies and protective behaviours, and strategies to overcome challenges in implementing sexual health prevention behaviours. Focus groups were audio-recorded and transcribed verbatim. Data were analysed using thematic analysis.

RESULTS

Women described challenges in uptake of existing low-cost sexual health prevention strategies such as condoms. They identified strategies to facilitate use of prevention tools, and to increase protective behaviours relating to sexual health during the transition from incarceration to the community. For example, women described methods for eroticising male and female condoms, including selecting condoms with novel features, explaining to partners that condoms could increase sexual pleasure, and incorporating condom application into foreplay and/or oral sex.

CONCLUSION

Incorporating these insights, including how to eroticise safe sex, can inform the design of future preventive interventions tailored to meet the urgent sexual health needs of incarcerated women preparing for reintegration into the community.

Early Childbearing, School Attainment, and Cognitive Skills: Evidence From Madagascar

Female secondary school attendance has recently increased in sub-Saharan Africa, and so has the risk of becoming pregnant while attending school. We analyze the impact of teenage pregnancy on young women’s human capital using longitudinal data in Madagascar that capture the transition from adolescence to adulthood for a cohort aged 21–24 in 2012, first interviewed in 2004. We find that early childbearing increases the likelihood of dropping out of school and decreases the chances of completing secondary school. This pregnancy-related school dropout also has a detrimental impact on standardized test scores in math and French. We instrument early pregnancy with the young woman’s community-level access and her exposure to condoms since age 15 after controlling for pre-fertility socioeconomic conditions. Our results are robust to different specifications that address potential endogeneity of program placement and instrument validity.

Enhancing condom use experiences among young men to improve correct and consistent condom use: feasibility of a home-based intervention strategy (HIS-UK)

BACKGROUND

Condoms remain the main protection against sexually transmitted infections (STIs) when used correctly and consistently. Yet, there are many reported barriers to their use such as negative attitudes, reduced sexual pleasure, fit-and-feel problems and erection difficulties. The UK home-based intervention strategy (HIS-UK) is a behaviour change condom promotion intervention for use among young men (aged 16-25 years) designed to increase condom use by enhancing enjoyment of condom-protected intercourse. The objective of this feasibility study was to test HIS-UK for viability, operability and acceptability. Along with an assessment of the recruitment strategy and adherence to the intervention protocol, the study tested the reliability and suitability of a series of behavioural and condom use outcome measures to assess condom use attitudes, motivations, self-efficacy, use experience, errors and problems and fit and feel.

METHODS

The HIS-UK intervention and associated assessment instruments were tested for feasibility using a single-arm, repeated measures design with baseline measurement and two follow-up measurements over 3 months. A 3-month target of 50 young men completing the baseline questionnaire was set. Twenty process and acceptability evaluation interviews with participants and health promotion professionals were conducted post trial.

RESULTS

Of the 61 young men who registered for the study, 57 completed the baseline questionnaire and 33 met with the study researcher to receive the HIS-UK condom kit. Twenty-one young men remained for the duration of the study (64% retention). The Cronbach's alpha scores for the condom use outcome measures were 0.84 attitudes, 0.78 self-efficacy, 0.83 use experience, 0.69 errors and problems and 0.75 fit and feel. Participant and health professional feedback indicated strong acceptability of the intervention.

CONCLUSIONS

The feasibility study demonstrated that our recruitment strategy was appropriate and the target sample size was achieved. Adherence was favourable when compared to other similar studies. The condom use measures tested proved to be fit-for-purpose with good internal consistency. Some further development and subsequent piloting of HIS-UK is required prior to a full randomised controlled trial, including the feasibility of collecting STI biomarkers, and assessment of participant acceptance of randomisation.

Can text messages increase safer sex behaviours in young people? Intervention development and pilot randomised controlled trial

BACKGROUND

Younger people bear the heaviest burden of sexually transmitted infections (STIs). Partner notification, condom use and STI testing can reduce infection but many young people lack the knowledge, skills and confidence needed to carry out these behaviours. Text messages can provide effective behavioural support. The acceptability and feasibility of a randomised controlled trial of safer sex support delivered by text message are not known.

OBJECTIVES

To assess the acceptability and feasibility of a randomised controlled trial of a safer sex intervention delivered by text message for young people aged 16-24 years.

DESIGN

(1) Intervention development; (2) follow-up procedure development; (3) a pilot, parallel-arm randomised controlled trial with allocation via remote automated randomisation (ratio of 1 : 1) (participants were unmasked, whereas researchers analysing samples and data were masked); and (4) qualitative interviews.

SETTING

Participants were recruited from sexual health services in the UK.

PARTICIPANTS

Young people aged 16-24 years diagnosed with chlamydia or reporting unprotected sex with more than one partner in the last year.

INTERVENTIONS

A theory- and evidence-based safer sex intervention designed, with young people's input, to reduce the incidence of STIs by increasing the correct treatment of STIs, partner notification, condom use and STI testing before unprotected sex with a new partner. The intervention was delivered via automated mobile phone messaging over 12 months. The comparator was a monthly text message checking contact details.

MAIN OUTCOME MEASURES

(1) Development of the intervention based on theory, evidence and expert and user views; (2) follow-up procedures; (3) pilot trial primary outcomes: full recruitment within 3 months and follow-up rate for the proposed primary outcomes for the main trial; and (4) participants' views and experiences regarding the acceptability of the intervention.

RESULTS

In total, 200 participants were randomised in the pilot trial, of whom 99 were allocated to the intervention and 101 were allocated to the control. We fully recruited early and achieved an 81% follow-up rate for our proposed primary outcome of the cumulative incidence of chlamydia at 12 months. There was no differential follow-up between groups. In total, 97% of messages sent were successfully delivered to participants' mobile phones. Recipients reported that the tone, language, content and frequency of messages were appropriate. Messages reportedly increased knowledge of and confidence in how to use condoms and negotiate condom use and reduced stigma about STIs, enabling participants to tell a partner about a STI.

CONCLUSIONS

Our research shows that the intervention is acceptable and feasible to deliver. Our pilot trial demonstrated that a main trial is feasible. It remains unclear which behaviour change techniques and elements of the intervention or follow-up procedures are associated with effectiveness. A further limitation is that in the trial one person entering data and the participants were unmasked. A randomised controlled trial to establish the effects of the intervention on STIs at 12 months is needed.

Feasibility and Preliminary Effectiveness of the Homework Intervention Strategy (eHIS) Program to Enhance Male Condom Use: Research Protocol

BACKGROUND

Although condoms are effective in reducing the risk of sexually transmitted infections (STIs) and unintended pregnancy, they are still often not used consistently and correctly. Negative impact on sensation and pleasure, ruining the mood, causing problems with maintaining erection, and condom slippage or breakage are some of the reasons given by men explaining why they do not want to use condoms. Although many interventions promoting condom use exist, some of them delivered online are complex and time- and resource-intensive. The Homework Intervention Strategy (eHIS) program, adapted from the existing face-to-face Kinsey Institute Homework Intervention Strategy (KIHIS) program, aims to address these issues by encouraging men to focus on sensation and pleasure when trying different types of condoms and lubricants in a low-pressure situation (on their own, without a partner present).

OBJECTIVE

The objectives of this study are to assess the feasibility, acceptability, and users' engagement with the eHIS program, its preliminary effectiveness in increasing condom use frequency and consistency, as well as the feasibility of the program's evaluation approach, including choice of measures and participant recruitment and retaining strategies (primary outcomes). Secondary outcomes include condom use experience, condom use attitudes, condom use self-efficacy, condom use errors and problems, and condom fit-and-feel. All of these will be analyzed in the context of participants' demographics, sexual history, and previous condom use.

METHODS

The study has a pre-post-test, within-subjects design. Men aged 18 to 69 and living in the United Kingdom are recruited through posters, leaflets, social media, and emails. Study participants are asked to complete T1 (baseline) measures before entering the eHIS website. After completing the T1 measures, they can order a free condoms and lubricants kit and have access to the eHIS website for 4 weeks. During that time they are asked to practice using different types of condoms and lubricants on their own in a no-pressure situation. Following T1, participants are asked to complete the T2 and T3 measures at 4 and 10 weeks, respectively.

RESULTS

Data collection for the study is completed. Data analysis is in progress and is expected to be completed by February 2018.

CONCLUSIONS

This brief, home-based, self-guided program may lead to increased consistent and correct condom use. Online delivery can make the program an easily accessible and low-cost health promotion intervention, which has the potential to reach a wide and diverse audience. If results of the current study show the program's feasibility and preliminary effectiveness in changing condom use related outcomes, a larger scale randomized controlled trial (RCT) will be conducted.

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.

A systematic review of randomised control trials of sexual health interventions delivered by mobile technologies

Background

Sexually transmitted infections (STIs) pose a serious public health problem globally. The rapid spread of mobile technology creates an opportunity to use innovative methods to reduce the burden of STIs. This systematic review identified recent randomised controlled trials that employed mobile technology to improve sexual health outcomes.

Methods

The following databases were searched for randomised controlled trials of mobile technology based sexual health interventions with any outcome measures and all patient populations: MEDLINE, EMBASE, PsycINFO, Global Health, The Cochrane Library (Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, Cochrane Methodology Register, NHS Health Technology Assessment Database, and Web of Science (science and social science citation index) (Jan 1999–July 2014). Interventions designed to increase adherence to HIV medication were not included. Two authors independently extracted data on the following elements: interventions, allocation concealment, allocation sequence, blinding, completeness of follow-up, and measures of effect. Trials were assessed for methodological quality using the Cochrane risk of bias tool. We calculated effect estimates using intention to treat analysis.

Results

A total of ten randomised trials were identified with nine separate study groups. No trials had a low risk of bias. The trials targeted: 1) promotion of uptake of sexual health services, 2) reduction of risky sexual behaviours and 3) reduction of recall bias in reporting sexual activity. Interventions employed up to five behaviour change techniques. Meta-analysis was not possible due to heterogeneity in trial assessment and reporting. Two trials reported statistically significant improvements in the uptake of sexual health services using SMS reminders compared to controls. One trial increased knowledge. One trial reported promising results in increasing condom use but no trial reported statistically significant increases in condom use. Finally, one trial showed that collection of sexual health information using mobile technology was acceptable.

Conclusions

The findings suggest interventions delivered by SMS interventions can increase uptake of sexual health services and STI testing. High quality trials of interventions using standardised objective measures and employing a wider range of behavioural change techniques are needed to assess if interventions delivered by mobile phone can alter safer sex behaviours carried out between couples and reduce STIs.

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.

Efficacy of a combined contraceptive regimen consisting of condoms and emergency contraception pills

Background

To evaluate and compare the effectiveness of the combined regimen (consisting of condoms and emergency contraception pills (ECP)) and using condoms only for the purpose of preventing pregnancy.

Methods

One-thousand-five-hundred-and-sixty-two (1,562) couples as volunteers enrolled at nine centers in Shanghai. Eight-hundred-and-twelve (812) were randomized to use male condoms and ECP (i.e., Levonorgestrel) as a back-up to condoms (the intervention group) and 750 to use male condoms only(the control group), according to their working unit. Participants were visited at admission and at the end of 1, 3, 6, 9, and 12 months. The cumulative life table rates were calculated for pregnancy and other reasons for discontinuation.

Result

The gross cumulative life table rates showed that the cumulative discontinuation rates for all reasons during the year of follow-up in the condoms plus emergency contraception group and the condoms only group were 7.76 ± 0.94 and 6.61 ± 0.91, respectively, per 100 women (χ2 = 0.41, p = 0.5227). The cumulative gross pregnancy rate of the condoms plus emergency contraception group and the condoms only group were 2.17 ± 0.52 and 1.25 ± 0.41, respectively, per 100 women (χ2 = 1.93, p = 0.1645). The Pearl Index in the condoms plus emergency contraception group and the condoms only group were 2.21% and 1.26%, respectively.

Conclusion

Male condoms remain a highly effective contraceptive method for a period of one year while consistently and correctly used. In addition, the lowest pregnancy rate followed from perfect use condom.

Combination prevention: new hope for stopping the epidemic

HIV research has identified approaches that can be combined to be more effective in transmission reduction than any 1 modality alone: delayed adolescent sexual debut, mutual monogamy or sexual partner reduction, correct and consistent condom use, pre-exposure prophylaxis with oral antiretroviral drugs or vaginal microbicides, voluntary medical male circumcision, antiretroviral therapy (ART) for prevention (including prevention of mother to child HIV transmission [PMTCT]), treatment of sexually transmitted infections, use of clean needles for all injections, blood screening prior to donation, a future HIV prime/boost vaccine, and the female condom. The extent to which evidence-based modalities can be combined to prevent substantial HIV transmission is largely unknown, but combination approaches that are truly implementable in field conditions are likely to be far more effective than single interventions alone. Analogous to PMTCT, "treatment as prevention" for adult-to-adult transmission reduction includes expanded HIV testing, linkage to care, antiretroviral coverage, retention in care, adherence to therapy, and management of key co-morbidities such as depression and substance use. With successful viral suppression, persons with HIV are far less infectious to others, as we see in the fields of sexually transmitted infection control and mycobacterial disease control (tuberculosis and leprosy). Combination approaches are complex, may involve high program costs, and require substantial global commitments. We present a rationale for such investments and cite an ongoing research agenda that seeks to determine how feasible and cost-effective a combination prevention approach would be in a variety of epidemic contexts, notably that in a sub-Saharan Africa.

Social network-based interventions to promote condom use: a systematic review

Effective sexually transmitted infection (STIs)/HIV prevention programs are urgently needed, but translating evidence-based methods of STI/HIV prevention into sustainable programs has been difficult. Social influences are critical for establishing condom use norms. This study systematically reviewed social network-based interventions focused on condom promotion. Social networks were defined as groups who self-identified prior to the research study. Eleven eligible research studies were identified and included in this review. Only three studies measured biological endpoints and five studies used validated measures of condom use. Among the nine studies with control groups, eight showed significant improvements in at least one measure of condom use. There were large differences in how social network members were identified and involved in the interventions. This systematic review highlights the potential utility of social network-based condom promotion programs. More research is needed to show how these promising studies can be expanded.

Interactive computer-based interventions for sexual health promotion

BACKGROUND

Sexual health promotion is a major public health challenge; there is huge potential for health promotion via technology such as the Internet.

OBJECTIVES

To determine effects of interactive computer-based interventions (ICBI) for sexual health promotion, considering cognitive, behavioural, biological and economic outcomes.

SEARCH STRATEGY

We searched more than thirty databases for randomised controlled trials (RCTs) on ICBI and sexual health, including CENTRAL, DARE, MEDLINE, EMBASE, CINAHL, British Nursing Index, and PsycINFO. We also searched reference lists of published studies and contacted authors. All databases were searched from start date to November 2007, with no language restriction.

SELECTION CRITERIA

RCTs of interactive computer-based interventions for sexual health promotion, involving participants of any age, gender, sexual orientation, ethnicity or nationality. 'Interactive' was defined as packages that require contributions from users to produce tailored material and feedback that is personally relevant.

DATA COLLECTION AND ANALYSIS

Two review authors screened abstracts, applied eligibility and quality criteria and extracted data. Results of RCTs were pooled using a random-effects model with standardised mean differences (SMDs) for continuous outcomes and odds ratios (ORs) for binary outcomes. We assessed heterogeneity using the I(2) statistic. Separate meta-analyses were conducted by type of comparator: 1) minimal intervention such as usual practice or leaflet, 2) face-to-face intervention or 3) a different design of ICBI; and by type of outcome (cognitive, behavioural, biological outcomes).

MAIN RESULTS

We identified 15 RCTs of ICBI conducted in various settings and populations (3917 participants). Comparing ICBI to 'minimal interventions' such as usual practice, meta-analyses showed statistically significant effects as follows: moderate effect on sexual health knowledge (SMD 0.72, 95% CI 0.27 to 1.18); small effect on safer sex self-efficacy (SMD 0.17, 95% CI 0.05 to 0.29); small effect on safer-sex intentions (SMD 0.16, 95% CI 0.02 to 0.30); and also an effect on sexual behaviour (OR 1.75, 95% CI 1.18 to 2.59). Data were insufficient for meta-analysis of biological outcomes and analysis of cost-effectiveness.In comparison with face-to-face sexual health interventions, meta-analysis was only possible for sexual health knowledge, showing that ICBI were more effective (SMD 0.36, 95% CI 0.13 to 0.58). Two further trials reported no difference in knowledge between ICBI and face-to-face intervention, but data were not available for pooling. There were insufficient data to analyse other types of outcome.No studies measured potential harms (apart from reporting any deterioration in measured outcomes).

AUTHORS' CONCLUSIONS

ICBI are effective tools for learning about sexual health, and they also show positive effects on self-efficacy, intention and sexual behaviour. More research is needed to establish whether ICBI can impact on biological outcomes, to understand how interventions might work, and whether they are cost-effective.
