HIV/STI risk-reduction intervention efficacy with South African adolescents over 54 months

Pregnancy and STI/HIV prevention intervention preferences of South African adolescent girls: findings from a cultural consensus modelling qualitative study

South African adolescent girls experience high rates of unintended pregnancy and sexually transmitted infections including HIV. To inform culturally-tailored dual protection interventions to prevent both unintended pregnancy and STIs/HIV, this study qualitatively examined girls' sexual health intervention preferences. Participants were aged 14-17 years old and Sesotho-speaking (N = 25). To elucidate shared cultural beliefs, individual interviews examined participants' perceptions about other adolescent girls' pregnancy and STI/HIV prevention intervention preferences. Interviews were conducted in Sesotho and translated into English. Two independent coders identified key themes in the data using a conventional content analysis approach with discrepancies resolved by a third coder. Participants indicated that intervention content should include efficacious pregnancy and STI/HIV prevention methods and ways to navigate peer pressure. Interventions should be accessible, avoid criticism and provide high-quality information. Preferred intervention formats included online, SMS/text, or delivery by social workers or older, knowledgeable peers, with mixed acceptability for delivery by parents or same-age peers. Schools, youth centres and sexual health clinics were preferred intervention settings. Results highlight the importance of cultural context in tailoring dual protection interventions to address the reproductive health disparities among adolescent girls in South Africa.

A reanalysis of the Institute for Research and Evaluation report that challenges non-US, school-based comprehensive sexuality education evidence base

Comprehensive sexuality education (CSE) prepares young people to make informed decisions about their sexuality. A review by the Institute of Research and Evaluation that analysed 43 CSE studies in non-US settings found the majority to be ineffective and concluded that there was little evidence of the effectiveness of CSE. We reanalysed the review to investigate its validity. We found several weaknesses with the review's methodology and analysis: (1) there was an absence of a clearly articulated search strategy and specific eligibility criteria; (2) the authors put forth criteria for programme effectiveness but included studies that did not collect the data needed to show programme effectiveness and thus several studies were determined to be ineffective by default; (3) the analytical framework minimised positive intervention effects and privileged negative intervention effects; and (4) there were errors in the data extracted, with 74% of studies containing one or more discrepancies. Overall, our reanalysis reveals that the IRE review suffers from significant methodological flaws and contains many errors which compromise its conclusions about CSE. Our reanalysis is a tool for the international community to refute CSE opposition campaigns based on poor science.

Shared Components of Worldwide Successful Sexuality Education Interventions for Adolescents: A Systematic Review of Randomized Trials

A crucial aspect of human development is sexuality which has implications for health, particularly in adolescence, since unfavorable sexual experiences may result in physical and mental problems. Sexuality education interventions (SEI) are one of the most used actions to promote sexual health in adolescents. Nevertheless, there is variability across their components; therefore, key elements for an effective SEI targeted at adolescents (A-SEI) are not well known. Based on this background, this study aims to identify the shared components of successful A-SEI through a systematic review of randomized controlled trials (RCT). This study followed the preferred reporting items for systematic reviews and meta-analyses statement. A search was conducted in CINAHL, PsycInfo, PubMed, and Web of Science between November and December 2021. A total of 21 studies passed the inclusion test after the review of 8318 reports. A total of 18 A-SEIs were identified in these studies. The components analyzed were the intervention's approach, dose, type of intervention, theoretical framework, facilitators' training, and intervention methodology. The results established that components that should be present in the design of an effective A-SEI are behavior change theoretical models, the use of participatory methodology, be targeted at mixed-sex groups, facilitators' training, and at least ten hours of weekly intervention.

Effects of economic support, comprehensive sexuality education and community dialogue on sexual behaviour: Findings from a cluster-RCT among adolescent girls in rural Zambia

Adolescent girls in Sub-Saharan Africa are at high risk of poor sexual and reproductive health outcomes. We present findings from a cluster-randomised trial in rural Zambia on the effects of economic support, comprehensive sexuality education (CSE) and community dialogue on sexual activity, contraceptive use and beliefs among adolescent girls. We recruited 157 schools in 2016, and all girls in grade 7 were invited to participate. Schools were randomised to either economic support, combined economic support, CSE and community dialogue, or control. Economic support consisted of unconditional cash transfers to girls and their guardians, and payment of school fees for girls continuing to grades eight and nine. CSE and community dialogue meetings focused on practices around girls' fertility, marriage and education. The interventions lasted two years from 2016 to 2018, with follow-up for another two years. The effects on outcomes were measured in 2018 and 2019 and compared using generalised estimating equations. We found that economic support lowered sexual activity (risk ratio (RR) 0.70; 95% C.I. 0.54 to 0.91), with a small added benefit of CSE and community dialogue. Economic support and the additional CSE and community dialogue were effective in lowering unprotected sexual activity (RR 0.53 for combined support vs. control; 95% C.I. 0.37 to 0.75). There was no evidence of intervention effects on contraceptive use among those ever sexually active, but the addition of CSE and community dialogue improved contraceptive use among those recently sexually active (RR 1.26; 95% C.I. 1.06 to 1.50) and knowledge regarding contraceptives (RR 1.18; 95% C.I. 1.01 to 1.38) compared to economic support alone. Perceived community support regarding contraceptives was lower in both intervention arms compared to the control. These findings indicate that economic support in combination with CSE and community dialogue can improve the sexual and reproductive health of adolescent girls.

The Efficacy of a Smartphone Game to Prevent HIV Among Young Africans: Protocol for a Randomized Controlled Trial in the Context of COVID-19

BACKGROUND

Adolescents contribute slightly less than one-third of all new HIV infections in sub-Saharan Africa. There is a need for more effective intervention approaches to help young adolescents safely navigate through adolescence and into adulthood. We are assessing the efficacy of Tumaini, a smartphone game designed to prevent HIV among young Africans. Against the background of COVID-19, meaningful alteration of the research protocol was necessary to ensure successful implementation and retention of the study participants in ongoing research.

OBJECTIVE

The objective of our protocol is to determine (1) if Tumaini delays sexual debut and increases condom use at first sex and (2) whether it influences behavioral mediators of early and unprotected sex.

METHODS

Participants were recruited from Kisumu County in Western Kenya. This study is a 2-arm, individual-randomized controlled trial that enrolled 1004 adolescents aged between 12 years and 15 years. The intervention arm participants are playing Tumaini, while the control arm is provided with Brainilis, a commercially available control game. The study period will last 45 months. At baseline, participants in both arms completed a baseline survey and biological testing for HIV and herpes simplex virus, type 2 (HSV-2); participants will have annual game play periods in years 1-3. They will also complete a total of 12 follow-up surveys. At endline, repeat biological testing will be conducted. Protocol adaptations were necessitated by the COVID-19 pandemic and implemented in accordance with local public health guidelines.

RESULTS

Participants were enrolled between October 2020 and November 2020. We plan to complete study procedures in September 2024. The enrolled participant sample was 50.1% (499/996) female and had a mean age of 14.0 (SD 0.6) years.

CONCLUSIONS

This ongoing research demonstrates that, with appropriate revisions to planned protocol activities guided by the need to maintain study integrity, protect both study participants and staff, and adhere to institutional review board and local health authority guidelines, human subject research is possible in the context of a global pandemic. If the trial demonstrates efficacy, Tumaini would provide an alternative, remote means of delivering age-appropriate education to adolescents on safer sex, HIV prevention, and effective life skills on a highly scalable, low-cost, and culturally adaptable platform.

Interventions to Promote a Healthy Sexuality among School Adolescents: A Scoping Review

Schools are particularly suitable contexts for the implementation of interventions focused on adolescent sexual behavior. Sexual education and promotion have a multidisciplinary nature. Nurses' role and the spectrum of the carried-out interventions is not clear. We aimed to identify interventions that promote a healthy sexuality among school adolescents. Our review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews and was registered in the Open Science Framework. Published articles on sexuality in adolescents in school contexts were considered. The research limitations included primary studies; access in full text in English, Spanish, or Portuguese; and no data publication limitation. Research was carried out on the EBSCOhost, PubMed, SciELO, and Web of Science platforms; gray literature and the bibliographies of selected articles were also searched. A total of 56 studies were included in the sample. The studies used a broad range of research methods, and 10 types of interventions were identified. Multi-interventional programs and socio-emotional interventions showed a greater impact on long-term behavioral changes, and continuity seemed to be a key factor. Long-term studies are needed to reach a consensus on the effectiveness of interventions. Nurses' particular role on the multidisciplinary teams was found to be a gap in the research, and must be further explored.

A Systematic Review of Randomized Controlled Trials of School Based Interventions on Sexual Risk Behaviors and Sexually Transmitted Infections Among Young Adolescents in Sub-Saharan Africa

Young adolescents in Sub-Saharan Africa (SSA) are at high risk of involvement in sexual risk behaviors; and curable sexually transmitted infections (STI), herpes simplex virus type 2 (HSV-2), human immunodeficiency virus (HIV) and unintended pregnancies remain persistently high in this population. Evidence based strategies are urgently needed to improve these outcomes. The aim of this systematic review was to synthesize the evidence from randomized controlled trials (RCT) to determine whether school-based interventions promote safe sex behaviors, reduce sexual risk behaviors and risk of curable STIs, HSV-2, HIV and unintended pregnancies among young adolescents aged 9-19 years in SSA. Electronic databases were searched for published studies and manual searches were conducted through reviewing of references of cited literature in the English language up to December 2019. Two independent reviewers screened and abstracted the data. We identified 428 articles and data from nine RCTs (N = 14,426 secondary school students) that fulfilled the selection criteria were analysed. Two studies measured pregnancy as an outcome and showed significant declines in unintended pregnancies. Of the five studies that measured HIV/AIDS related-knowledge, condom-use outcomes (normative beliefs, knowledge, and self-efficacy) and attitudes to HIV testing, four showed significant improvements. Of the six studies that measured sexual debut, four reported moderate but non-significant declines and in two studies sexual debut information was either incomplete or unreliable. One study measured curable STIs and found no significant declines; whilst the second study that measured HSV-2 and HIV, no significant declines were observed. This review highlights the need to undertake well-designed research studies to provide evidence on the impact of interventions on curable STIs, HSV-2 and HIV, critical to improving the health of young adolescents.

South African Fathers Involvement and Their Adolescents' Sexual Risk Behavior and Alcohol Consumption

Although considerable research has examined the influence of parent-adolescent relationships on the sexual health of adolescents, there is a great need for research to understand the influence of fathers on their children's HIV sexual risk behavior, particularly in sub-Saharan Africa. We examined how the residence and the involvement of fathers are related to their children's HIV sexual risk and alcohol consumption behaviors. A cross-sectional survey was completed by 175 sixth-grade adolescents in the Eastern Cape Province, South Africa. Analyses showed that adolescents living with their fathers had fewer sexual partners (B = - 0.606, SE = 0.299, p = .043) and consumed alcohol less frequently (B = - 0.642, SE = 0.294, p = .029). Adolescents who spent more quality days with their fathers in the past 30 days had fewer sexual partners (B = - 0.103, SE = 0.039, p = .008) and had condomless sex less frequently (B = - 0.097, SE = 0.047, p = 0.041). It was also found that there were significant father-residence × child-gender interactions on sexual debut (B = 1.132, SE = 0.564, p = .045) and on frequency of condomless sex (B = - 2.140, SE = 0.924, p = .021). These interactions indicate that boys living with their fathers were less likely to have had vaginal intercourse than girls and that girls living with their fathers were less likely to have unprotected sex than boys. This study highlights the importance of South African fathers' roles in their adolescent children's HIV sexual risk and alcohol drinking behaviors and the need to promote father-child relationships for adolescent health. The results suggest that health programs aiming to reduce South African adolescents' HIV sexual risk behaviors and alcohol consumption consider strategies that target their fathers.

Acceptability, safety, and patterns of use of oral tenofovir disoproxil fumarate and emtricitabine for HIV pre-exposure prophylaxis in South African adolescents: an open-label single-arm phase 2 trial

BACKGROUND

HIV incidence among adolescents in southern Africa remains unacceptably high. Pre-exposure prophylaxis (PrEP) is an effective HIV prevention intervention but there are few data on its implementation among adolescents. We aimed to investigate the safety, feasibility, and acceptability of PrEP with oral tenofovir disoproxil fumarate and emtricitabine as part of a comprehensive HIV prevention package in an adolescent population in South Africa.

METHODS

This open-label single-arm phase 2 study (PlusPills) was done in two research clinics in Cape Town and Johannesburg, South Africa. Adolescents aged 15-19 years were recruited into the study through recruitment events and outreach in the community. Potential participants were eligible for enrolment if they reported being sexually active. Exclusion criteria were a positive test for HIV or pregnancy at enrolment, breastfeeding, or any relevant co-morbidities. Participants were given oral tenofovir disoproxil fumarate and emtricitabine for PrEP to take daily for the first 12 weeks and were then given the choice to opt in or out of PrEP use at three monthly intervals during scheduled clinic visits. Participants were invited to monthly visits for adherence counselling and HIV testing during the study period. The primary outcomes were acceptability, use, and safety of PrEP. Acceptability was measured by the proportion of participants who reported willingness to take up PrEP and remain on PrEP at each study timepoint. Use was defined as the number of participants who continued to use PrEP after the initial 12-week period until the end of the study (week 48). Safety was measured by grade 2, 3, and 4 laboratory and clinical adverse events using the Division of AIDS table for grading the severity of adult and paediatric adverse events, version 1.0. Dried blood spot samples were collected at each study time-point to measure tenofovir diphosphate concentrations. This trial is registered with ClinicalTrials.gov, NCT02213328.

FINDINGS

Between April 28, 2015, and Nov 11, 2016, 244 participants were screened, and 148 participants were enrolled (median age was 18 years; 99 participants [67%] were female) and initiated PrEP. PrEP was stopped by 26 of the 148 (18%) participants at 12 weeks. Cumulative PrEP opt-out, from the total cohort, was 41% (60 of 148 participants) at week 24 and 43% (63 of 148 participants) at week 36. PrEP was well tolerated with only minor adverse events (grade 2) thought to be related to study drug, which included headache (n=4, 3%), gastrointestinal upset (n=8, 5%), and skin rash (n=2, 1%). Two participants (1%) experienced grade 3 weight loss, which was deemed related to the study drug and resolved fully when PrEP was discontinued. Tenofovir diphosphate concentrations were detectable (>16 fmol/punch) in dried blood spot samples in 108 (92%) of 118 participants who reported PrEP use at week 12, in 74 (74%) of 100 participants at week 24, and in 22 (59%) of 37 participants by the study end at week 48.

INTERPRETATION

In this cohort of self-selected South African adolescents at risk of HIV acquisition, PrEP appears safe and tolerable in those who continued use. PrEP use decreased throughout the course of the study as the number of planned study visits declined. Adolescents in southern Africa needs access to PrEP with tailored adherence support and possibly the option for more frequent and flexible visit schedules.

How Sexuality Education Programs Have Been Evaluated in Low-and Lower-Middle-Income Countries? A Systematic Review

Background: Complex sexual and reproductive health interventions, such as sexuality education (SE), contain multiple components and activities, which often requires a comprehensive evaluation design and adaptation to a specific context. In this review, we synthetize available scientific literature on types of evaluation designs used for SE programs in low- and lower-middle-income countries. Methods: Two databases yielded 455 publications, from which 20 articles met the inclusion criteria. Narrative synthesis was used to summarize the findings. Evaluation approaches were compared to recommended evaluation frameworks. The quality of articles was assessed by using MMAT 2018. Results: A total of 15 interventions employed in 10 countries were evaluated in the 20 selected articles, with the quality of publications being moderate to high. Randomized controlled trial was the predominant study design, followed by quasi-experimental design. There were seven process evaluation studies, using mixed methods. Main outcomes reported were of public health or behavioral nature—condom use, sexual debut or delay, and number of sexual partners. By comparing evaluation designs to recommended frameworks, few studies fulfilled at least half of the criteria. Conclusions: Evaluations of SE are largely dominated by quantitative (quasi-)experimental designs and use of public health outcomes. To improve understanding of SE program effectiveness, it is important to assess the quality of the program development, its implementation, and its impact, using existing evaluation frameworks and recommendations.

PrEP Stigma, HIV Stigma, and Intention to Use PrEP among Women in New York City and Philadelphia

Background

Stigma is an important contributor to the continued HIV epidemic in the United States (US). In 2016, women made up nearly one in five of all new infections. Pre-exposure HIV Prophylaxis or PrEP is a medication that can be taken to prevent HIV acquisition; however, PrEP is significantly underutilized by women at risk for infection. How PrEP stigma relates to PrEP initiation among women is not well understood.

Methods

Surveys were completed by 160 PrEP-eligible women aged 18-55 in Philadelphia, PA and New York City, NY. Associations between PrEP stigma, HIV stigma, and PrEP initiation intention were modeled using multinomial logistic regression, controlling for sociodemographic and theoretically-relevant variables.

Results

Participants ranged in age from 18 to 55 years (M = 40.2; SD = 11.78). Most (79%) identified as Black or African-American and/or Latina and 36% had completed high-school or less. Higher PrEP stigma was significantly associated with lower PrEP initiation intention, while controlling for other theoretically-relevant and sociodemographic variables. HIV stigma was not related to PrEP initiation intention.

Conclusions

HIV prevention interventions seeking to increase PrEP initiation among PrEP-eligible, urban women need to address the role that PrEP stigma plays in PrEP uptake.

The effect of HIV educational interventions on HIV-related knowledge, condom use, and HIV incidence in sub-Saharan Africa: a systematic review and meta-analysis

BACKGROUND

As high stigmatization of HIV and relatively low knowledge of HIV transmission and prevention measures persist in Sub-Saharan Africa, the improvement of HIV-related knowledge, and the evaluation of which types of interventions are most effective in this regard, is an important aspect of further prevention efforts. In addition, it is of interest to assess whether improvements in HIV-related knowledge may actually lead to increased engagement in preventive behaviours and ultimately lower HIV transmission. This study therefore aims to systematically review and meta-analyse the evidence for the effect of HIV-related knowledge interventions on 1) the improvement of HIV-related knowledge, 2) subsequent risk reduction behaviour (condom use), 3) lower incidence of HIV infection.

METHODS

A literature search was conducted using the Embase and Medline databases, returning 746 after duplicate removal. Following abstract and full-text screening, 36 studies were ultimately included in the final review. Meta-analyses were conducted in R, using random-effects models, for the HIV-related knowledge, condom use, and HIV incidence outcomes, where sufficient data were available.

RESULTS

Interventions assessed in the reviewed studies varied, including computer-based interventions, mass media campaigns, and peer education interventions. The interventions were generally found to be effective at improving HIV-related knowledge in the target population, with 10 studies reporting improved knowledge of risk reduction through condom use in the intervention group (out of 11 studies reporting data for this outcome), with 6 reporting these differences as significant (p < 0.05). Regarding knowledge of transmission routes, studies assessing peer education interventions often reported significant improvements in the intervention group. Meta-analysis results showed significantly higher odds among the intervention groups of correct knowledge of: risk reduction through condom use (OR: 3.09, 95%CI: 1.83-5.22, p < 0.0001), sexual transmission of HIV (OR: 5.86, 95%CI: 2.65-12.97, p < 0.001) and transmission through sharps (OR: 4.35, 95%CI = 3.21-5.90, p < 0.001), but non-significantly lower odds of HIV infection (OR: 0.97, 95%CI: 0.66-1.41, p = 0.854).

CONCLUSION

Peer-education-based interventions appear to be particularly effective in facilitating the uptake of HIV-related knowledge, particularly pertaining to transmission routes. There is some evidence that improved knowledge of HIV transmission and prevention facilitates increased subsequent engagement in preventive measures, although this requires further exploration.

A high burden of asymptomatic genital tract infections undermines the syndromic management approach among adolescents and young adults in South Africa: implications for HIV prevention efforts

BACKGROUND

Youth in southern Africa, particularly adolescent girls and young women, are a key population for HIV prevention interventions. Untreated genital tract infections (GTIs) increase both HIV transmission and acquisition risks. South African GTI treatment guidelines employ syndromic management, which relies on individuals to report GTI signs and symptoms. Syndromic management may, however, underestimate cases, particularly among youth. We compared genital tract infection (GTI) prevalence by symptom-based and laboratory assessment among sexually-experienced youth in South Africa, overall and stratified by sex.

METHODS

Interviewer-administered surveys assessed socio-demographics, behaviors, and GTI symptoms among 352 youth (16-24 yrs., HIV-negative or unknown HIV status at enrollment) enrolled in community-based cohorts in Durban and Soweto (2014-2016). Laboratory tests assessed HIV, Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), Mycoplasma genitalium (MG), Trichomonas vaginalis (TV) infections and, among females, bacterial vaginosis (BV) and Candida species. Youth with genital ulcers were tested for HSV-2 and syphilis. We assessed sensitivity (and specificity) of symptom-based reporting in identifying laboratory-confirmed GTIs.

RESULTS

At baseline, 16.2% of females (32/198) and < 1% (1/154) of males reported ≥1 GTI symptom. However, laboratory tests identified ≥1 GTI in 70.2% and 10.4%, respectively. Female CT prevalence was 18.2%, NG 7.1%, MG 9.6%, TV 8.1%, and 5.1% were newly diagnosed with HIV. BV prevalence was 53.0% and candidiasis 9.6%. One female case of herpes was identified (0 syphilis). Male CT prevalence was 7.8%, NG 1.3%, MG 3.3%, TV < 1%, and 2.0% were newly diagnosed with HIV. Overall, 77.8% of females and 100% of males with laboratory-diagnosed GTIs reported no symptoms or were asymptomatic. Sensitivity (and specificity) of symptom-based reporting was 14% (97%) among females and 0% (99%) among males.

CONCLUSION

A high prevalence of asymptomatic GTIs and very poor sensitivity of symptom-based reporting undermines the applicability of syndromic GTI management, thus compromising GTI control and HIV prevention efforts among youth. Syndromic GTI management does not meet the sexual health needs of young people. Policy changes incorporating innovations in GTI diagnostic testing are needed to reduce GTIs and HIV-associated risks among youth.

[Trends in Research on Adolescent Sexuality Education, Fertility Awareness, and the Possibility of Life Planning Based on Reproductive Health Education]

In this paper, we describe the trends in research on adolescent sexuality education in Japan and other countries and on fertility awareness, as well as the possibility of life planning based on sex and reproductive health education. Mason-Jones AJ et al. reviewed the results of school-based intervention studies on the prevention of human immunodeficiency virus infection, sexually transmitted diseases, and pregnancy. There is little evidence supporting the idea that educational curriculum-based programs alone are effective in improving sex and reproductive health outcomes in adolescents. In another study, the effectiveness of school-based sexuality education for adolescents in Japan was evaluated. The Japan Medical Abstract Society was searched for articles published in the last 10 years. In many studies, the effects were compared before and after a single sexuality education lecture by professionals, such as doctors, midwives, and public health nurses. In Japan, effort has been directed toward sexuality education, but no systematic program based on behavior theory has been adopted. Therefore, sex education is insufficient. A third study clarified research on fertility awareness in adults and issues regarding improvements in related education and research. The Japan Medical Abstract Society and PubMed were searched for articles published in the last 10 years. The review suggested that awareness of female fertility is insufficient. Delaying childbearing based on inaccurate knowledge of the decline in female fertility could lead to unintended infertility. For males and females, sexual health education in schools and communities should include information on the age-related decline in female fertility. Although the determinants of the timing of childbearing are multifactorial, education on fertility issues is necessary to help adults make informed reproductive decisions based on accurate information. Finally, in this paper, we introduce examples of the pioneering efforts in sexual health education through collaboration between the governments of Oita and Okayama Prefectures and Oita and Okayama Universities.

Effect of a Behavioral Intervention on Perpetrating and Experiencing Forced Sex Among South African Adolescents: A Secondary Analysis of a Cluster Randomized Trial

IMPORTANCE

Scant research has investigated interventions to reduce forced sexual intercourse among adolescents. The need for such interventions is especially great in South Africa, which has some of the highest rates of sexual assault in the world.

OBJECTIVES

To determine whether an HIV/sexually transmitted disease risk-reduction intervention that reduced sexual risk behavior and sexually transmitted disease prevalence also reduced the perpetration and experience of forced sex among South African adolescents.

DESIGN, SETTING, AND PARTICIPANTS

A cluster randomized clinical trial, at schools located in a township and a semirural area, Eastern Cape Province, South Africa. Matched pairs of schools were randomly selected (9 of 17); of 1118 students in sixth grade at these 18 schools who had parent or guardian consent, 1057 (94%) were enrolled, and those not reporting forced sex perpetration before the intervention were included in the analyses (n = 1052). Post hoc secondary analysis of a cluster randomized clinical trial was performed, with baseline and 3-, 6-, 12-, 42-, and 54-month postintervention assessments between October 4, 2004, and June 30, 2010. Generalized estimating equation Poisson regression analyses adjusting for gender and clustering within schools were conducted between August 23, 2017, and April 30, 2018. Recruiters and data collectors, but not intervention facilitators, were blind to the participants' intervention assignment.

INTERVENTIONS

Theory-based, culturally adapted, 6-session HIV/sexually transmitted disease risk-reduction intervention (Let Us Protect Our Future intervention) and attention-matched, chronic disease prevention control intervention implemented by specially trained man and woman cofacilitators from the community.

MAIN OUTCOMES AND MEASURES

Study outcomes for this secondary analysis (planned after the data were collected) are self-reports of perpetrating and experiencing forced vaginal intercourse.

RESULTS

Participants included 1052 adolescents (557 girls [53%]; mean [SD] age, 12.4 [1.2] years) reporting not perpetrating forced sex at baseline. Fewer intervention than control participants reported forced sex perpetration postintervention compared with the control group at 3 months (9 of 561 [2%] vs 20 of 491 [4%]; risk ratio [RR], 0.978; 95% CI, 0.959-0.997), 6 months (17 of 561 [3%] vs 35 of 491 [7%]; RR, 0.964; 95% CI, 0.941-0.988), 12 months (21 of 561 [4%] vs 42 of 491 [9%]; RR, 0.959; 95% CI, 0.934-0.985), 42 months (41 of 561 [7%] vs 56 of 491 [11%]; RR, 0.967; 95% CI, 0.937-0.998), and 54 months (52 of 561 [9%] vs 68 of 491 [14%]; RR, 0.964; 95% CI, 0.932-0.997).

CONCLUSIONS AND RELEVANCE

In settings with high rates of sexual assault, the use of theory-based culturally adapted interventions with early adolescents may reduce rates of perpetrating and experiencing forced sex.

A Smartphone Game-Based Intervention (Tumaini) to Prevent HIV Among Young Africans: Pilot Randomized Controlled Trial

Background

There is a pressing need to ensure that youth in high HIV prevalence settings are prepared for a safer sexual debut. Smartphone ownership is increasing dramatically in low-income and middle-income countries. Smartphone games that are appropriately grounded in behavioral theory and evidence-based practice have the potential to become valuable tools in youth HIV prevention efforts in Sub-Saharan Africa.

Objective

To pilot-test a theory-based, empirically grounded smartphone game for young Kenyans designed to increase age and condom use at first sex, aiming to establish directionality of effects on behavior change.

Methods

Tumaini (“hope for the future” in Swahili) is an interactive, narrative-based game grounded in social cognitive theory. A randomized controlled pilot study was conducted in Kisumu, Western Kenya, from April to June 2017 with 60 participants aged 11-14 (mean 12.7) years. Intervention arm participants (n=30) were provided with an Android smartphone with Tumaini installed on it and were instructed to play the game for at least 1 hour a day for 16 days; control arm participants (n=30) received no intervention. All participants completed a survey on behavioral mediators, delivered via an audio computer-assisted self-interview system at baseline (T1), post intervention (T2), and at 6 weeks postintervention (T3). The postintervention survey for intervention arm participants included questions eliciting feedback on the game. Intervention arm participants and their parents participated in 8 postintervention focus group discussions. Game log files were analyzed to calculate the length of exposure to the game. Behavioral survey data were analyzed using two-sample t tests to compare mean change from T1 to T2 and to T3 for intervention versus control arm participants. Descriptive statistics on game feedback questions were computed. Focus group transcripts were uploaded to MAXQDA software, where they were labeled with deductive and inductive codes. Data were analyzed thematically and compared across demographics.

Results

Intervention arm participants played Tumaini for a mean of approximately 27 hours. The intervention arm showed significant gains in sexual health-related knowledge and self-efficacy (both P<.001), behavioral intention for risk-avoidance strategies and sexual risk communication (P=.006), and overall survey scores (P<.001) compared with the control arm at T3. The postintervention survey revealed high subjective measures of the game’s value, relevance, and appeal. Focus groups identified a wide range of knowledge and skills the participants had gained, including setting goals and planning how to achieve them, which was perceived as a key motivator for avoiding or reducing risk.

Conclusions

The study supports the need for further research to assess the efficacy of the game-based intervention. If proven efficacious, smartphone games have the potential to dramatically increase the reach of culturally adapted behavioral interventions while ensuring fidelity to intervention design.

Sexual Self-Efficacy and Gender: A Review of Condom Use and Sexual Negotiation Among Young Men and Women in Sub-Saharan Africa

Sexual self-efficacy (SSE), one's perceived control of or confidence in the ability to perform a given sexual outcome, predicts sexual behavior; however, important questions remain regarding whether gender modifies observed associations. In a comprehensive review of peer-reviewed HIV-prevention literature focusing on youth (ages 10 to 25) in sub-Saharan Africa, we measured and assessed the influence of SSE on condom use and sexual refusal, overall and by gender. Our results, after reviewing 63 publications, show that SSE is inconsistently measured. Most studies measured condom use self-efficacy (CUSE) (96.8%) and/or sexual refusal self-efficacy (SRSE) (63.5%). On average, young men had higher CUSE than young women, while young women had higher SRSE than young men. While cross-sectional studies reported an association between high SSE and sexual behaviors, this association was not observed in interventions, particularly among young women who face a disproportionate risk of HIV acquisition. In all, 25% of intervention studies demonstrated that fostering CUSE increased condom use among young men only, and one of two studies demonstrated that higher SRSE led to reduced frequency of sexual activity for both men and women. Future research and HIV-prevention interventions must be gender targeted, consider improving CUSE for young men, and move beyond limited individual-level sexual behavior change frameworks.

Retention of South African Adolescents in a 54-Month Longitudinal HIV Risk Reduction Trial

Retention of participants in clinical trials is a central concern of HIV/STI behavioral researchers and research sponsors. This article describes the strategies used for addressing the challenges in retaining South African adolescents for a 54-month longitudinal study. The objective of the South African adolescent health promotion long-term follow-up trial was to test the sustainability of the effects of an HIV/STI risk reduction intervention, "Let Us Protect Our Future," on young adolescents as they aged into middle and late adolescence. Inaccurate contact information, invalid mobile telephone numbers, lack of transportation, transitory family addresses, and family relocation were among the challenges to retaining participants. Despite a significant gap in time of 36 months between the main trial and the long-term follow-up study, 99.2% of 1057 participants were retained. Solutions used for retaining the adolescents are discussed with suggestions offered for retaining adolescents in longitudinal HIV/STI prevention clinical trials in low resource countries.

Condom Use Efficacy and Sexual Communication Skills Among African American College Women

Despite condom use being the most protective measure against the transmission of human immunodeficiency virus (HIV), little is known about the intermediary relationships between condom negotiation, assertive sexual communication, and condom use efficacy. The purpose of the current study was to examine the relationships between these constructs within the context of an HIV prevention intervention. We examined two samples of African American college women participating in two HIV prevention interventions, one of which was based on social learning theory ( N = 214). Data collected at intervention posttest and 3-month follow-up were analyzed. Findings revealed that condom use efficacy at posttest fully mediated the relationship between intervention effect and assertive sexual communication at 3-month follow-up. In addition, condom use efficacy at posttest fully mediated the relationship between intervention effect and condom negotiation at 3-month follow-up. Implications of the importance of experiential learning, in combination with behavior observance, on the maintenance of condom protective behaviors are discussed. Findings have the potential to inform clinic and community-based HIV prevention interventions conducted among African American women.

School-based interventions for preventing HIV, sexually transmitted infections, and pregnancy in adolescents

BACKGROUND

School-based sexual and reproductive health programmes are widely accepted as an approach to reducing high-risk sexual behaviour among adolescents. Many studies and systematic reviews have concentrated on measuring effects on knowledge or self-reported behaviour rather than biological outcomes, such as pregnancy or prevalence of sexually transmitted infections (STIs).

OBJECTIVES

To evaluate the effects of school-based sexual and reproductive health programmes on sexually transmitted infections (such as HIV, herpes simplex virus, and syphilis), and pregnancy among adolescents.

SEARCH METHODS

We searched MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials (CENTRAL) for published peer-reviewed journal articles; and ClinicalTrials.gov and the World Health Organization's (WHO) International Clinical Trials Registry Platform for prospective trials; AIDS Educaton and Global Information System (AEGIS) and National Library of Medicine (NLM) gateway for conference presentations; and the Centers for Disease Control and Prevention (CDC), UNAIDS, the WHO and the National Health Service (NHS) centre for Reviews and Dissemination (CRD) websites from 1990 to 7 April 2016. We handsearched the reference lists of all relevant papers.

SELECTION CRITERIA

We included randomized controlled trials (RCTs), both individually randomized and cluster-randomized, that evaluated school-based programmes aimed at improving the sexual and reproductive health of adolescents.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed trials for inclusion, evaluated risk of bias, and extracted data. When appropriate, we obtained summary measures of treatment effect through a random-effects meta-analysis and we reported them using risk ratios (RR) with 95% confidence intervals (CIs). We assessed the certainty of the evidence using the GRADE approach.

MAIN RESULTS

We included eight cluster-RCTs that enrolled 55,157 participants. Five trials were conducted in sub-Saharan Africa (Malawi, South Africa, Tanzania, Zimbabwe, and Kenya), one in Latin America (Chile), and two in Europe (England and Scotland). Sexual and reproductive health educational programmesSix trials evaluated school-based educational interventions.In these trials, the educational programmes evaluated had no demonstrable effect on the prevalence of HIV (RR 1.03, 95% CI 0.80 to 1.32, three trials; 14,163 participants; low certainty evidence), or other STIs (herpes simplex virus prevalence: RR 1.04, 95% CI 0.94 to 1.15; three trials, 17,445 participants; moderate certainty evidence; syphilis prevalence: RR 0.81, 95% CI 0.47 to 1.39; one trial, 6977 participants; low certainty evidence). There was also no apparent effect on the number of young women who were pregnant at the end of the trial (RR 0.99, 95% CI 0.84 to 1.16; three trials, 8280 participants; moderate certainty evidence). Material or monetary incentive-based programmes to promote school attendanceTwo trials evaluated incentive-based programmes to promote school attendance.In these two trials, the incentives used had no demonstrable effect on HIV prevalence (RR 1.23, 95% CI 0.51 to 2.96; two trials, 3805 participants; low certainty evidence). Compared to controls, the prevalence of herpes simplex virus infection was lower in young women receiving a monthly cash incentive to stay in school (RR 0.30, 95% CI 0.11 to 0.85), but not in young people given free school uniforms (Data not pooled, two trials, 7229 participants; very low certainty evidence). One trial evaluated the effects on syphilis and the prevalence was too low to detect or exclude effects confidently (RR 0.41, 95% CI 0.05 to 3.27; one trial, 1291 participants; very low certainty evidence). However, the number of young women who were pregnant at the end of the trial was lower among those who received incentives (RR 0.76, 95% CI 0.58 to 0.99; two trials, 4200 participants; low certainty evidence). Combined educational and incentive-based programmesThe single trial that evaluated free school uniforms also included a trial arm in which participants received both uniforms and a programme of sexual and reproductive education. In this trial arm herpes simplex virus infection was reduced (RR 0.82, 95% CI 0.68 to 0.99; one trial, 5899 participants; low certainty evidence), predominantly in young women, but no effect was detected for HIV or pregnancy (low certainty evidence).

AUTHORS' CONCLUSIONS

There is a continued need to provide health services to adolescents that include contraceptive choices and condoms and that involve them in the design of services. Schools may be a good place in which to provide these services. There is little evidence that educational curriculum-based programmes alone are effective in improving sexual and reproductive health outcomes for adolescents. Incentive-based interventions that focus on keeping young people in secondary school may reduce adolescent pregnancy but further trials are needed to confirm this.

School-based sexual health education interventions to prevent STI/HIV in sub-Saharan Africa: a systematic review and meta-analysis

Background

School-based sexual health education has the potential to provide an inclusive and comprehensive approach to promoting sexual health among young people. We reviewed evaluations of school-based sexual health education interventions in sub-Saharan Africa to assess effectiveness in reducing sexually transmitted infections and promoting condom use.

Methods

We searched ten electronic databases, hand-searched key journals, and reference lists of included articles for potential studies. Data were extracted on outcomes, intervention characteristics, methods and study characteristics indicative of methodological quality. Where possible, data were synthesized using random effect meta-analysis. Intervention features found predominantly in effective interventions were noted.

Results

The initial search retrieved 21634 potentially relevant citations. Of these, 51 papers reporting on 31 interventions were included. No evaluation reported statistically significant effects on the incidence or prevalence of Human Immunodeficiency Virus and Herpes Simplex Virus 2 infections. However, intervention participants reported statistically significant greater condom use in both randomised controlled trials and non-randomised trials for short (less than 6 months) follow-up periods (OR = 1.62, 95 % CI = 1.03–2.55 and OR = 2.88, 95 % CI = 1.41–5.90 respectively). For intermediate (6–10 months) and long-term (more than 10 months) follow-up periods, the effect was statistically significant (OR = 1.40, 95 % CI = 1.16–1.68) and marginally significant (OR = 1.22, 95 % CI = 0.99–1.50) among the randomised trials respectively. Only 12 of the 31 interventions reported implementation details, out of which seven reported on fidelity.

Conclusion

School-based sexual health education has the potential to promote condom use among young people in sub-Saharan Africa. However, further work is needed to develop and evaluate interventions that have measurable effects on sexually transmitted infections.

Effects of PREPARE, a Multi-component, School-Based HIV and Intimate Partner Violence (IPV) Prevention Programme on Adolescent Sexual Risk Behaviour and IPV: Cluster Randomised Controlled Trial

Young South Africans, especially women, are at high risk of HIV. We evaluated the effects of PREPARE, a multi-component, school-based HIV prevention intervention to delay sexual debut, increase condom use and decrease intimate partner violence (IPV) among young adolescents. We conducted a cluster RCT among Grade eights in 42 high schools. The intervention comprised education sessions, a school health service and a school sexual violence prevention programme. Participants completed questionnaires at baseline, 6 and 12 months. Regression was undertaken to provide ORs or coefficients adjusted for clustering. Of 6244 sampled adolescents, 55.3 % participated. At 12 months there were no differences between intervention and control arms in sexual risk behaviours. Participants in the intervention arm were less likely to report IPV victimisation (35.1 vs. 40.9 %; OR 0.77, 95 % CI 0.61–0.99; t(40) = 2.14) suggesting the intervention shaped intimate partnerships into safer ones, potentially lowering the risk for HIV.

Partner violence, power, and gender differences in South African adolescents' HIV/sexually transmitted infections risk behaviors

OBJECTIVES

Low relationship power and victimization by intimate partner violence (IPV) have been linked to HIV risks among adult and adolescent women. This article examines associations of IPV and relationship power with sexual-risk behaviors and whether the associations differ by gender among South African adolescents.

METHOD

Sexual-risk behaviors (multiple partners in past 3 months; condom use at last sex), IPV, and relationship power were collected from 786 sexually experienced adolescents (mean age = 16.9) in Eastern Cape Province, South Africa, during the 54-month follow-up of a HIV/sexually transmitted infection (STI) risk-reduction intervention trial. The data were analyzed with logistic regression models.

RESULTS

Adolescent boys were less likely to report condom use at last sex (p = .001) and more likely to report multiple partners (p < .001). A Gender × IPV interaction (p = .002) revealed that as IPV victimization increased, self-reported condom use at last sex decreased among girls, but increased among boys. A Gender × Relationship Power interaction (p = .004) indicated that as relationship power increased, self-reported condom use at last sex increased among girls, but decreased among boys. A Gender × IPV interaction (p = .004) indicated that as IPV victimization increased, self-reports of having multiple partners increased among boys, but not among girls. As relationship power increased, self-reports of having multiple partners decreased irrespective of gender.

CONCLUSIONS

HIV risk-reduction interventions and policies should address gender differences in sexual-risk consequences of IPV and relationship power among adolescents and promote gender equity. (PsycINFO Database Record

Mediation of effects of a theory-based behavioral intervention on self-reported physical activity in South African men

OBJECTIVE

Increasing physical activity is an important public-health goal worldwide, but there are few published mediation analyses of physical-activity interventions in low-to-middle-income countries like South Africa undergoing a health transition involving markedly increased mortality from non-communicable diseases. This article reports secondary analyses on the mediation of a theory-of-planned-behavior-based behavioral intervention that increased self-reported physical activity in a trial with 1181 men in Eastern Cape Province, South Africa.

METHOD

Twenty-two matched-pairs of neighborhoods were randomly selected. Within pairs, neighborhoods were randomized to a health-promotion intervention or an attention-matched control intervention with baseline, immediate-post, and 6- and 12-month post-intervention assessments. Theory-of-planned-behavior constructs measured immediately post-intervention were tested as potential mediators of the primary outcome, self-reported physical activity averaged over the 6- and 12-month post-intervention assessments, using a product-of-coefficients approach in a generalized-estimating-equations framework. Data were collected in 2007-2010.

RESULTS

Attitude, subjective norm, self-efficacy, and intention were significant mediators of intervention-induced increases in self-reported physical activity. The descriptive norm, not affected by the intervention, was not a mediator, but predicted increased self-reported physical activity.

CONCLUSION

The results suggest that interventions targeting theory-of-planned-behavior constructs may contribute to efforts to increase physical activity to reduce the burden of non-communicable diseases among South African men.
