'Let Us Protect Our Future' a culturally congruent evidenced-based HIV/STD risk-reduction intervention for young South African adolescents

Meta-analysis of the effectiveness of educational programs about HIV prevention on knowledge, attitude, and behavior among adolescents

The prevalence of human immunodeficiency virus (HIV) among adolescents is on the rise due to a lack of comprehensive knowledge, leading to suboptimal attitudes and behaviors, which emphasizes the critical need for targeted interventions. The aim of this review study was to evaluate the effectiveness of educational interventions for HIV prevention among adolescents by assessing their impact on knowledge, attitude, and behavior. A systematic review of seven databases: PubMed, Science Direct, Cochrane, JSTOR, Embase, Scopus, and EBSCO were identified, and 14 eligible randomized controlled trials published until June 2023 were included. Two independent authors assessed quality appraisal using the Risk of Bias 2.0. Outcomes were measured using the standard mean difference (SMD) with random effects model and a 95% confidence interval. Subgroup analyses and meta-regression were performed to explore heterogeneity. The results showed significant improvements in participants' knowledge (SMD: 1.13, 95%CI: 0.78-1.49), behavior intentions (SMD: 1.22, 95%CI: 0.37-2.07), and attitude (SMD: 0.48, 95%CI: 0.02-0.95) after receiving HIV prevention education programs. Interventions grounded in theoretical principles and incorporating technology, group settings, and audio-visual aids were found to be effective in enhancing knowledge of HIV prevention and promoting behavioral intentions. Peer-led education positively impacted both knowledge and attitude. Moreover, excluding parents from these programs was identified as a crucial factor in improving adolescents' knowledge of HIV prevention. In conclusion, educational programs focused on HIV effectively enhance adolescents' knowledge, attitudes, and behavioral intentions among adolescents. Professionals planning interventions should consider these impactful components in designing comprehensive strategies.

The Impact of a Comic Book Intervention on East African-American Adolescents' HPV Vaccine-Related Knowledge, Beliefs and Intentions

HPV vaccine uptake is low among East African-American (EAA) adolescents. We developed a comic book and evaluated the impact on HPV/HPV-vaccine knowledge, beliefs and vaccine intentions. The intervention was delivered to HPV-unvaccinated EAA adolescents attending educational dinners with their mothers. Adolescents aged 14-17 were sequentially assigned alternately to a pre- or post-test. Results were compared with chi-squared tests and generalized estimating equation models adjusted for age, gender, and mother's language. Among 136 (pre-test = 64, post-test = 72) participants (90% Somali), pre/post differences were observed for proportions of correct responses to questions on HPV (44.0% vs. 82.9%, RR:1.87[95%CI 1.54-2.27]), HPV-vaccine knowledge (42.8% vs. 75.4%, RR:1.74[95%CI 1.46-2.07]), comfort discussing HPV/HPV vaccine with parents (57.8% vs. 90.3% somewhat/very comfortable, RR:1.55[95%CI 1.24-1.94]), and willingness (37.5% vs. 83.3% probably/definitely willing, RR:2.16[95%CI 1.55-3.01]) and intention (34.4% vs. 86.1% somewhat/very likely, RR:2.38[95%CI:1.69-3.37]) to get vaccinated. The intervention improved participants' HPV/HPV-vaccine knowledge, beliefs and vaccine intentions. Similar interventions could be adapted for other racial/ethnic minorities.

Implementation Science for the Prevention and Treatment of HIV among Adolescents and Young Adults in Sub-Saharan Africa: A Scoping Review

Despite many evidence-based adolescent and young adult (AYA) HIV interventions, few are implemented at scale in sub-Saharan Africa (SSA). A growing implementation science literature provides important context for scaling up AYA HIV interventions in this high HIV-burden region. This scoping review examined the use of implementation research in AYA HIV studies conducted in SSA. We searched five databases and included articles which focused on AYA (10-24 years old), addressed HIV prevention or treatment, were conducted exclusively in SSA countries, and included an implementation science outcome. We included 44 articles in 13 SSA countries. Most were in East (52.3%) and South Africa (27.3%), and half focused exclusively on HIV prevention components of the care continuum. Acceptability and feasibility were the most cited implementation science outcomes. Only four articles used an established implementation science framework. The findings informed our recommendations to guide the design, implementation, and dissemination of further studies and health policymaking.

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.

Mediation Analysis of a Theory-Based Culture and Age-Appropriate HIV/STI Prevention

Few studies have investigated mediator effects of HIV prevention interventions on adolescents in sub-Saharan Africa. Herein, we report on a secondary analysis of an intervention that increased intentions to use condoms, abstain from sexual intercourse, and seek safe male circumcision among adolescents in Botswana. In a study conducted in Botswana, 806 grade 9 students from 21 public Junior Secondary Schools were randomly assigned to either the OWN THE FUTURE: Pulling Together We Will" ( PTWW) intervention group or a health promotion control group. Both conditions consisted of 12 1-h modules, with two modules delivered during each of the six sessions on six consecutive school days. The students in both groups completed confidential computer-based surveys at several time points: pre-, immediately post-, 3, 6, and 12 months post-intervention. Mediation was assessed using the product-of-coefficients approach in a generalized estimating equations (GEE) framework. The analyses showed that condom use beliefs were significant mediators of the intervention effect on the intention to consistently use condoms over time. Also, negative socio-cultural beliefs, prevention beliefs, and HIV/STI knowledge were significant mediators of the intervention's effects on the intention to abstain from sex. Additionally, normative beliefs, prevention beliefs, parental negotiation, and circumcision knowledge were significant mediators of the intervention's effect on intention to seek safe male circumcision. The mediation analysis delineated a theoretical model and isolated activities that positively impact condom use, abstinence from sex, and circumcision intentions of Batswana middle school adolescents.

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.

Gender norms and sexual behaviours among Indigenous youth of the Comarca Ngäbe-Buglé, Panama

The Comarca Ngäbe-Buglé, an administratively autonomous Indigenous region in western Panama, is home to a significant population rural Indigenous people of Ngäbe and Buglé ethnicity. HIV prevalence in the Comarca is two times higher than the national average, and the great majority of cases are concentrated in young men. Yet, there is little data regarding socio-cultural and sexual behaviour factors that may drive this high prevalence. Understanding such factors would enable the development of relevant prevention interventions. We conducted a qualitative study between January and March 2018, consisting of 20 semi-structured interviews with male and female young people aged 14-19 years, complemented with ethnographic observations of one month's duration each in two communities within the Comarca, to identify potential factors that could increase risk of HIV and other sexually transmitted infections (STIs). We suggest that interventions to prevent HIV and other STIs should focus on increasing open communication between sex partners, especially with respect to condom use, as well as facilitating people-driven change in gender norms that are harmful to both young women and young men.

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.

A Smartphone Game to Prevent HIV among Young Kenyans: Household Dynamics of Gameplay in a Feasibility Study

OBJECTIVE

mHealth interventions often favour individual-level effects. This is particularly problematic in contexts where social support and shifts in social norms are critical to sustained behaviour change. Mobile digital games represent a promising health education strategy for youth, including in low-resource settings. We sought to better understand the interpersonal and social interactions that can be elicited by digital games for health.

DESIGN

We piloted Tumaini, a smartphone game rooted in interactive narrative designed to prevent HIV among young Africans (aged 11-14), in a randomised controlled feasibility study and analysed reports of the household dynamics surrounding gameplay. Following a 16-day intervention period, phone gameplay log files were downloaded and intervention arm participants (n=30) completed a gameplay experience survey; eight focus group discussions were held, four with intervention arm participants (n=27), four with their parents (n=22).

SETTING

This study took place in Kisumu, Kenya, in Spring 2017.

METHOD

Descriptive statistics were computed from survey responses and log files. Focus group transcripts were labelled, analysed thematically, and compared demographically using MaxQDA software.

RESULTS

Data from log files, survey and focus groups indicate that the game generated considerable interaction and dialogue with parents, siblings, and friends, and served as a catalyst for children to act as advocates for healthful decisions about sex, both within the family and beyond. The game showed a high level of acceptability with parents.

CONCLUSION

Serious digital games using a smartphone platform can generate considerable household interaction. Games can model and facilitate these exchanges, maximising multi-level effects. An additional app for parents could reinforce these effects.

Childhood Obesity Prevention in Africa: A Systematic Review of Intervention Effectiveness and Implementation

Childhood obesity is of increasing concern in many parts of Africa. We conducted a systematic search and review of published literature on behavioural childhood obesity prevention interventions. A literature search identified peer-reviewed literature from seven databases, and unindexed African journals, including experimental studies targeting children age 2–18 years in African countries, published in any language since 1990. All experimental designs were eligible; outcomes of interest were both behavioural (physical activity, dietary behaviours) and anthropometric (weight, body mass index, body composition). We also searched for process evaluations or other implementation observations. Methodological quality was assessed; evidence was synthesised narratively as a meta-analysis was not possible. Seventeen articles describing 14 interventions in three countries (South Africa, Tunisia and Uganda) were included. Effect scores indicated no overall effect on dietary behaviours, with some beneficial effects on physical activity and anthropometric outcomes. The quality of evidence was predominantly weak. We identified barriers and facilitators to successful interventions, and these were largely resource-related. Our systematic review highlights research gaps in targeting alternative settings to schools, and younger age groups, and a need for more rigorous designs for evaluating effectiveness. We also recommend process evaluations being used more widely.

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.

Preliminary Impacts of an HIV-Prevention Program Targeting Out-of-School Youth in Postconflict Liberia

Adolescents in Sub-Saharan Africa account for greater HIV/STI (human immuno defiency virus/sexually transmitted infection) burdens and difficult-to-reach populations. This study implemented a community-based HIV/STI program to reach at-risk youth aged 15 to 17 years in postconflict Liberia. Using a randomized controlled trial, community youths were assigned to an adapted version of an effective HIV/STI program, Making Proud Choices, or attention-matched comparison curriculum, General Health Program. Both programs were of similar doses, reach and coverage, and administered in classroom settings by trained health educators. The findings suggest that the adapted HIV/STI program had positive effects on knowledge, sexual refusal and condom use self-efficacy, condom negotiation self-efficacy, positive condom attitudes, parental communication about sex, and negative condom attitudes over time. Culturally adapted community-based, behavioral-driven programs can positively affect mediators of sexual behaviors in at-risk adolescents in postconflict settings. This is the first published report of an evidence-based HIV/STI program on sexual risk-taking behaviors of community youths in Liberia.

Gender differences in prevalence and correlates of high sexual self-efficacy among adolescents in Soweto, South Africa: implications for gender-sensitive research and programming

Sexual self-efficacy (SSE) - one's confidence in their ability to perform given sexual behaviours, has been shown to predict adolescents' HIV-prevention practices (e.g., Condom use). Few studies within sub-Saharan Africa, where HIV incidence and prevalence disproportionately affects young women, have examined gendered differences in SSE. We used multivariable logistic regression to identify correlates of high-SSE separately among adolescent men and women (aged 14-19) in Soweto, South Africa using a previously validated SSE scale (high-SSE [>3/6 items]; study-alpha = 0.75). SSE scale items assessed self-efficacy related to sexual refusal and condom use. Adolescent women were significantly more likely to report high-SSE than adolescent men (72.3% versus 49.5%; p < 0.01). High-SSE among adolescent men was associated with more positive beliefs about sexual relationships and negatively associated with probable depression. High-SSE among adolescent women was associated with increased HIV knowledge, more positive beliefs about condom use and sexual relationships, having an adult in the home, and negatively associated with being an older adolescent (16-17 versus ≤15), and ever experiencing physical violence. Differences in prevalence and correlates of SSE among adolescent men and women in South Africa highlight important areas for gender-sensitive interventions. Targeted efforts to reduce negative sexual beliefs, improve HIV knowledge and mental well-being may improve SSE and thus the uptake of HIV-prevention practices among adolescent men. For adolescent women, findings indicate programming should move beyond individual-levels determinants of behaviour to focus on improving enabling environments (e.g., Reduced violence and improved family relationships) in which sexual agency can be enacted.

Sexual and reproductive health priorities of adolescent girls in Lagos, Nigeria: findings from free-listing interviews

Background Adolescent girls in Nigeria experience a disproportionately high burden of sexual and reproductive health disparities that affect their well-being. Yet, little is known about adolescent girls' own unique perspectives of the sexual and reproductive health challenges they face, and possible solutions to these challenges. Aims To explore top sexual and reproductive health concerns of female adolescents in Nigeria and their perceptions regarding potential solutions to these issues. Methods Eighty adolescent girls attending two public secondary schools in Lagos, Nigeria completed individual free-listing interviews. Items assessed their perceptions of the most important sexual and reproductive health issues and potential solutions to these issues at the individual and societal level. Data were analyzed using Anthropac 4.98 to sort the lists by item frequency as well as to determine Smith's salience index (S). Results The top five sexual and reproductive health concerns identified by participants were human immunodeficiency virus (HIV)/acquired immune deficiency syndrome (AIDS), followed by menstrual pain, vaginal infections, sexual abuse and teenage pregnancy. Adolescent girls stated that youth empowerment programs that provide access to skills-building opportunities and mentors was one potential strategy for addressing their sexual and reproductive health priorities. Other solutions identified were access to medical checkups, general health talks focused on their sexual and reproductive health concerns as well as access to health facilities and opportunities to build self-efficacy skills. Conclusion Adolescent girls in Nigeria need to be engaged in becoming powerful agents in improving their own sexual and reproductive health, and in crafting solutions that may be effective in enabling them to achieve their full potential and rights to health and well-being. The findings will be used to develop an intervention targeting the sexual and reproductive health priorities of adolescent girls in Lagos, Nigeria.

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.

Age-targeted HIV treatment and primary prevention as a 'ring fence' to efficiently interrupt the age patterns of transmission in generalized epidemic settings in South Africa

BACKGROUND

Generalized HIV epidemics propagate to future generations according to the age patterns of transmission. We hypothesized that future generations could be protected from infection using age-targeted prevention, analogous to the ring-fencing strategies used to control the spread of smallpox.

METHODS

We modeled age-targeted or cohort-targeted outreach with HIV treatment and/or prevention using EMOD-HIV v0·8, an individual-based network model of HIV transmission in South Africa.

RESULTS

Targeting ages 20 to 30 with intensified outreach, linkage, and eligibility for antiretroviral therapy (ART) averted 45% as many infections as universal outreach for approximately one-fifth the cost beyond existing HIV services. Though cost-effective, targeting failed to eliminate all infections to those under 20 due to vertical and inter-generational transmission. Cost-effectiveness of optimal prevention strategies included US$6238 per infection averted targeting ages 10-30, US$5031 targeting 20-30, US$4279 targeting 22-27, and US$3967 targeting 25-27, compared to US$10 812 for full-population test-and-treat. Minimizing burden (disability-adjusted life years [DALYs]) rather than infections resulted in older target age ranges because older adults were more likely to receive a direct health benefit from treatment.

CONCLUSIONS

Age-targeted treatment for HIV prevention is unlikely to eliminate HIV epidemics, but is an efficient strategy for reducing new infections in generalized epidemics settings.

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 an efficacious HIV risk reduction intervention for South African men

"Men, Together Making a Difference!" is an HIV/STD risk-reduction intervention that significantly increased self-reported consistent condom use during vaginal intercourse compared with a health-promotion attention-control intervention among men (N = 1181) in Eastern Cape Province, South Africa. The present analyses were designed to identify mediators of the intervention's efficacy. The potential mediators were Social Cognitive Theory (SCT) constructs that the intervention targeted, including several aspects of condom-use self-efficacy, outcome expectancies, and knowledge. Mediation was assessed using a product-of-coefficients approach where an α path (the intervention's effect on the potential mediator) and a β path (the potential mediator's effect on the outcome of interest, adjusting for intervention) were estimated independently in a generalized estimating equations framework. Condom-use negotiation self-efficacy, technical-skill self-efficacy, and impulse-control self-efficacy were significant mediators. Although not mediators, descriptive norm and expected friends' approval of condom use predicted subsequent self-reported condom use, whereas the expected approval of sexual partner did not. The present results suggest that HIV/STD risk-reduction interventions that draw upon SCT and that address self-efficacy to negotiate condom use, to apply condoms correctly, and to exercise sufficient control when sexually aroused to use condoms may contribute to efforts to reduce sexual risk behavior among South African men. Future research must examine whether approaches that build normative support for condom use among men's friends are also efficacious.

A 1-year follow-up evaluation of a sexual-health education program for Spanish adolescents compared with a well-established program

BACKGROUND

Competencies for adolescents with a healthy sexuality (COMPAS) is the only school-based sexual health promotion program in Spain that has been found to be as effective as an evidence-based intervention (¡Cuídate!) in the short term. This study's aim was to compare data from a 12-month follow-up evaluation on the effects of COMPAS on adolescents' sexual risks (knowledge, attitudes, perceived norms, sexual risk perception and intentions) and sexual behaviours (age of the first sex, consistent condom use and multiple partners) with an evidence-based intervention (¡Cuídate!) and a control group.

METHODS

Eighteen schools from five provinces of Spain were randomly assigned to one of three conditions: COMPAS, ¡Cuídate! and a control group. The adolescents (N = 1563; 34% attrition) were evaluated 1 week before and after the program, and 1 year post-program implementation.

RESULTS

We found that the COMPAS program was as effective as ¡Cuídate!, the evidence-based program, in increasing the adolescents' knowledge about sexually transmitted infections and in fostering favourable attitudes about condom use and people living with HIV/AIDS. COMPAS was more effective than ¡Cuídate! in increasing the adolescents' perceptions of their peer's consistent condom use and the age delay of their first vaginal intercourse. However, it was less effective in maintaining the adolescents' intentions to use condoms and in delaying the age of their first oral sex experience.

CONCLUSION

COMPAS was as effective as ¡Cuídate! in reducing sexual risk among adolescents.

Teen Drivers' Perceptions of Inattention and Cell Phone Use While Driving

OBJECTIVE

Inattention to the roadway, including cell phone use while driving (cell phone calls, sending and reading texts, mobile app use, and Internet use), is a critical problem for teen drivers and increases risk for crashes. Effective behavioral interventions for teens are needed in order to decrease teen driver inattention related to cell phone use while driving. However, teens' perceptions of mobile device use while driving is a necessary component for theoretically driven behavior change interventions. The purpose of this study was to describe teen drivers' perceptions of cell phone use while driving in order to inform future interventions to reduce risky driving.

METHODS

We conducted 7 focus groups with a total of 30 teen drivers, ages 16-18, licensed for ≤ 1 year in Pennsylvania. The focus group interview guide and analysis were based on the Theory of Planned Behavior, identifying the attitudes, perceived behavioral control, and norms about inattention to the roadway. Directed descriptive content analysis was used to analyze the focus group interviews. All focus groups were coded by 2 research team members and discrepancies were reconciled. Themes were developed based on the data.

RESULTS

Teens had a mean age of 17.39 (SD = 0.52), mean length of licensure of 173.7 days (SD = 109.2; range 4-364), were 50% male and predominately white (90%) and non-Hispanic (97%). From the focus group data, 3 major themes emerged: (1) Recognizing the danger but still engaging; (2) Considering context; and (3) Formulating safer behaviors that might reduce risk. Despite recognizing that handheld cell phone use, texting, and social media app use are dangerous and distracting while driving, teens and their peers often engaged in these behaviors. Teens described how the context of the situation contributed to whether a teen would place or answer a call, write or respond to a text, or use a social media app. Teens identified ways in which they controlled their behaviors, although some still drew attention away from the roadway.

CONCLUSIONS

Cell phone use while driving is a contributor to motor vehicle crashes in teens, and effective interventions to decrease risks are needed. Teens viewed some types of cell phone use as unsafe and describe methods in which they control their behaviors. However, some of their methods still take attention off the primary task of driving. Teens could benefit from behavior change interventions that propose strategies to promote focused attention on the roadway at all times during the driving trip.

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

OBJECTIVE

Little research has tested HIV/sexually transmitted infection (STI) risk-reduction interventions' effects on early adolescents as they age into middle and late adolescence. This study tested whether intervention-induced reductions in unprotected intercourse during a 12-month period endured over a 54-month period and whether the intervention reduced the prevalence of STIs, which increase risk for HIV.

METHOD

Grade 6 learners (mean age = 12.4 years) participated in a 12-month trial in Eastern Cape Province, South Africa, in which 9 matched pairs of schools were randomly selected and within pairs randomized to a theory-based HIV/STI risk-reduction intervention or an attention-control intervention. They completed 42- and 54-month postintervention measures of unprotected intercourse (the primary outcome), other sexual behaviors, theoretical constructs, and, at 42- and 54-month follow-up only, biologically confirmed curable STIs (chlamydial infection, gonorrhea, and trichomoniasis) and herpes simplex virus 2.

RESULTS

The HIV/STI risk-reduction intervention reduced unprotected intercourse averaged over the entire follow-up period (OR = 0.42, 95% CI [0.22, 0.84]), an effect not significantly reduced at 42- and 54-month follow-up compared with 3-, 6-, and 12-month follow-ups. The intervention caused positive changes on theoretical constructs averaged over the 5 follow-ups, although most effects weakened at long-term follow-up. Although the intervention's main effect on STIs was nonsignificant, an Intervention Condition × Time interaction revealed that it significantly reduced curable STIs at 42-month follow-up in adolescents who reported sexual experience.

CONCLUSION

These results suggest that theory-based behavioral interventions with early adolescents can have long-lived effects in the context of a generalized severe HIV epidemic.

Caregivers' intentions to disclose HIV diagnosis to children living with HIV in South Africa: a theory-based approach

When children know their HIV serostatus, they are more likely to cooperate with steps to manage their health and the risk of transmitting HIV to others. Mounting evidence indicates that caregivers often do not disclose to HIV-positive children that the children are living with HIV, but little is known about the modifiable determinants of pediatric HIV disclosure. The present study examined theory-of-planned-behavior predictors of the intention to disclose to children their HIV diagnosis. The participants were 100 caregivers of HIV-positive children in Eastern Cape Province, South Africa. Proportional-odds logistic regression analysis revealed that normative support for disclosure and caregiver-child communication predicted the intention to disclose, whereas behavioral beliefs regarding the consequences of disclosing and self-efficacy to disclose did not. The results suggest that interventions to increase pediatric HIV disclosure in South Africa should help caregivers enlist support for disclosure among important referents and improve communication with their HIV-infected children.
