Sexual abstinence only programmes to prevent HIV infection in high income countries: systematic review

Changes in Sexual Behaviors Due to Mpox: a Cross-Sectional Study of Sexual and Gender Minority Individuals in Illinois

The spread of the monkeypox virus (mpox) in 2022 primarily within the sexual networks of men who have sex with men (MSM) triggered a potentially stigmatizing public health response in the USA. Despite mpox being primarily spread through skin-to-skin contact, most messaging has promoted abstinence and/or reduction in sexual risk behaviors. More research is needed on decreases in sexual risk behaviors among sexual and gender minority (SGM) youth and young adults (YYA) related to the most recent mpox epidemic and whether there are factors associated with these decreases in sexual risk behavior. Participants within an ongoing cohort study of SGM YYA who reside in Illinois were offered the opportunity to participate in an mpox survey between September 10th and September 20th, 2022. Analyses looked at demographic factors associated with sexual activity since the start of the outbreak, as well as associations with two sexual risk reduction factors. Survey participation was 68.7% (322/469). Three-quarters of participants (82.6%) reported sexual activity since June 1st. Most sexually active participants (83.5%) adopted at least one sexual risk reduction behavior due to mpox. Black and Latinx individuals were less likely to be sexually active but more likely to report risk reduction behaviors (31.3% and 22.6%, respectively). Participants who received the mpox vaccine were more likely to report sexual activity. SGM YYA in Illinois reported that their sexual behaviors were impacted by the mpox outbreak. However, associations between vaccination and sexual behavior demonstrate that those who are vaccinated do adopt protective methods despite not decreasing sexual activity. Therefore, sex-positive communications and harm reduction messaging may be more appropriate as opposed to abstinence-only prevention, which can further stigmatize an already marginalized group.

Association Between Age of Anal Sex Debut and Adult Health Behaviors Among Sexual Minoritized Men Living with HIV

Earlier age of anal sex debut (ASD) has been linked with contemporary and long-term health outcomes, including vulnerability to HIV acquisition. The goal of this study was to utilize a life course approach to examine associations between earlier ASD and recent health behaviors among sexual minoritized men (SMM) living with HIV. A total of 1156 U.S. SMM living with HIV recruited from social and sexual networking apps and websites completed online surveys as part of a longitudinal eHealth intervention. Data from baseline surveys were analyzed to determine associations between age of ASD and adult health outcomes, including mental health, HIV viral load, and substance use. The median age of ASD among these participants was 17 years old, consistent with other work. Earlier ASD was significantly associated with a greater likelihood of past 2-week anxiety (AOR = 1.45, 95% CI 1.07-1.97) and past 3-month opioid use (AOR = 1.60, 95% CI 1.13-2.26); no significant associations were found for recent depression, HIV viral load, or stimulant use. Earlier ASD may function as an important proxy measure for deleterious health outcomes in adulthood, particularly recent anxiety and opioid use. Expansion of comprehensive and affirming sexual health education is critical to early engagement of individuals with a higher risk of HIV acquisition, with plausible downstream health benefits lasting into adulthood among SMM living with HIV.

Embracing dynamic public health policy impacts in infectious diseases responses: leveraging implementation science to improve practice

Rationale

The host-pathogen relationship is inherently dynamic and constantly evolving. Applying an implementation science lens to policy evaluation suggests that policy impacts are variable depending upon key implementation outcomes (feasibility, acceptability, appropriateness costs) and conditions and contexts.

COVID-19 case study

Experiences with non-pharmaceutical interventions (NPIs) including masking, testing, and social distancing/business and school closures during the COVID-19 pandemic response highlight the importance of considering public health policy impacts through an implementation science lens of constantly evolving contexts, conditions, evidence, and public perceptions. As implementation outcomes (feasibility, acceptability) changed, the effectiveness of these interventions changed thereby altering public health policy impact. Sustainment of behavioral change may be a key factor determining the duration of effectiveness and ultimate impact of pandemic policy recommendations, particularly for interventions that require ongoing compliance at the level of the individual.

Practical framework for assessing and evaluating pandemic policy

Updating public health policy recommendations as more data and alternative interventions become available is the evidence-based policy approach and grounded in principles of implementation science and dynamic sustainability. Achieving the ideal of real-time policy updates requires improvements in public health data collection and analysis infrastructure and a shift in public health messaging to incorporate uncertainty and the necessity of ongoing changes. In this review, the Dynamic Infectious Diseases Public Health Response Framework is presented as a model with a practical tool for iteratively incorporating implementation outcomes into public health policy design with the aim of sustaining benefits and identifying when policies are no longer functioning as intended and need to be adapted or de-implemented.

Conclusions and implications

Real-time decision making requires sensitivity to conditions on the ground and adaptation of interventions at all levels. When asking about the public health effectiveness and impact of non-pharmaceutical interventions, the focus should be on when, how, and for how long they can achieve public health impact. In the future, rather than focusing on models of public health intervention effectiveness that assume static impacts, policy impacts should be considered as dynamic with ongoing re-evaluation as conditions change to meet the ongoing needs of the ultimate end-user of the intervention: the public.

[Descriptive study about non-formal sex education resources available in Spain.]

OBJECTIVE

Sex education (SE) is a fundamental element of a fulfilling and safe life. Currently, education is understood beyond what happens inside the classroom. The aim of this research was to describe and to compare sex education resources available in official webs of Autonomous Communities of Spain (ACS) that to could be used in non-formal educational context.

METHODS

A review of the ACS official web pages related to healthcare, education, youth, family and equality was made. Finally, 216 resources were selected for descriptive analysis. The resources were classified based on United Nations Educational, Scientific and Cultural Organization's (UNESCO) Technical Guidelines.

RESULTS

64% of resources were targeted at young people/adolescents. 80% dealt some specific issues, the most frequent being Reproductive Health, Violence and Gender. Values and Rights related to sexuality, Skills for Health and Well-being and Sexual behaviour are issues rarely addressed. Only 6 ACS were a social network profile related to SE. ACS with the widest diversity of issues addressed were Andalusia, Asturias and the Canary Islands.

CONCLUSIONS

Homogeneity in the kind of resources and issues disparity reveals potential inequities in SE access in Spain. To enhance out-of-school environments learning can provide better successful health promotion. UNESCO's guidelines can be used to classify educational resource content and to identify the institutions that have best integrated actual SE paradigm.

Conflicting HIV/AIDS Sex Education Policies and Mixed Messaging among Educators and Students in the Lower Manya Krobo Municipality, Ghana

While school-based comprehensive sex education (CSE) is effective in HIV prevention among young people ages 10-24 years, Ghana's national sexual and reproductive health education policy promotes abstinence. Meanwhile, the Ministry of Health's HIV prevention programs provide more comprehensive school-based education. This qualitative study evaluated the HIV/AIDS education program in the Lower Manya Krobo Municipality to assess the perspectives of students and educators in 10 schools on school-based sexual and reproductive health programs, including HIV/AIDS education and conflicting HIV/AIDS sex education policies. HIV prevalence in the Lower Manya Krobo Municipality of Ghana was more than twice the national average at 5.64% in 2018, and prevalence among youth in the municipality aged 15-24 was the highest in the nation at 0.8%. Educators have mixed feelings regarding abstinence-based and CSE approaches. However, students generally endorse abstinence and describe the limitations of condom use. Ambiguity in overarching policies is identified as a factor that could influence the orientation of school-based health educators, create disharmony in sex education interventions, introduce confusing sex education messages to young people, and create a potentially narrow curriculum that limits the gamut of HIV/AIDS sex education to exclude young people's risky sexual behaviours and diverse teaching and implementation strategies. Policies and the scope of sex education should be realigned to ensure the transparent implementation of HIV/AIDS sex education programs in Ghana.

More comprehensive sex education reduced teen births: Quasi-experimental evidence

Sex education for youth in the United States has been the topic of considerable debate among researchers, policy makers, and the public at large. In this study, we focus attention on federal funding for more comprehensive sex education that was received by a mix of public and private organizations in 55 US counties. Our analyses provide population-level causal evidence that funding for more comprehensive sex education led to an overall reduction in the teen birth rate at the county level of more than 3%. This study thus contributes causal evidence relevant to ongoing debates on the potential role more comprehensive sex education may play in reducing teen births in the United States.

Women in the United States are much more likely to become mothers as teens than those in other rich countries. Teen births are particularly likely to be reported as unintended, leading to debate over whether better information on sex and contraception might lead to reductions in teen births. We contribute to this debate by providing causal evidence at the population level. Our causal identification strategy exploits county-level variation in the timing and receipt of federal funding for more comprehensive sex education and data on age-specific teen birth rates at the county level constructed from birth certificate natality data covering all births in the United States. Our results show that federal funding for more comprehensive sex education reduced county-level teen birth rates by more than 3%. Our findings thus complement the mixed evidence to date from randomized control trials on teen pregnancies and births by providing population-level causal evidence that federal funding for more comprehensive sex education led to reductions in teen births.

Living through and with the global HIV/AIDS pandemic: Distinct 'pandemic practices' and temporalities

In this study, we expand on the newly devised sociological concept of pandemic practices that emerged during the COVID-19 outbreak by applying it to the HIV/AIDS pandemic. The analytical heuristic of pandemic practices distinguishes between four kinds of practices: (i) primary practices that encompass the public's direct response to the pandemic, (ii) responsive practices that encompass altered routines and social interactions, (iii) adaptive practices that encompass more elusive organisational and legal legacies and (iv) meta-practices that produce particular narratives about the pandemic dynamics that might lead to lasting socio-cultural behavioural changes. In this paper we probe further into the notion of meta-practices. The results show that the prolonged nature of the HIV/AIDS pandemic combined with the widespread stigmatisation of vulnerable groups has led to distinct social practices that fragment along socio-economic lines both internally in countries but also between high-income and low-income countries. As the COVID-19 pandemic becomes increasingly endemic, lessons learned from HIV/AIDS expose the dangers of similar fragmentations where parts of the population return to normal but where many others continue to suffer not only from adverse health outcomes but also social exclusion and stigmatisation. Thus, we argue that attention to pandemic practices, and how they produce and reinforce underlying socio-economic vulnerabilities would strengthen long-term pandemic responses.

Protective Factors That Foster Resilience to HIV/AIDS: Insights and Lived Experiences of Older Gay, Bisexual, and Other Men Who Have Sex with Men

Since the beginning of the HIV/AIDS epidemic, gay, bisexual, and other men who have sex with men (gbMSM) have been disproportionately impacted by HIV/AIDS health disparities. Research showed that resilience to HIV/AIDS is associated with increased use of relevant health services, lower sexual health risks, and improved mental health outcomes among racially and ethnically diverse gbMSM. As the subpopulation that has historically been impacted by HIV/AIDS the longest, older gbMSM living with HIV/AIDS have inarguably exhibited resilience to HIV/AIDS the most. The qualitative study described in this paper sought to identify and examine protective factors that fostered resilience to HIV/AIDS based on the insights and lived experiences of racially and ethnically diverse, older gbMSM. Applying a community-based participatory research approach that included the meaningful involvement of older gbMSM living with HIV/AIDS in different roles (i.e., advisory committee member, collaborator, peer researcher, and participant), the study recruited and included forty-one older gbMSM living with HIV/AIDS from Ontario, Canada, in confidential, semi-structured interviews. Utilizing thematic analysis, we identified three major themes from the participant interviews as factors that fostered the resilience of older gbMSM to HIV/AIDS and helped to address HIV/AIDS health disparities: (1) established protective factors, (2) behavioral protective factors, and (3) controversial protective factors. This paper argues for the importance of valuing and capitalizing on these protective factors in the conceptualization and development of interventions, services, and programs that are dedicated to fostering resilience to HIV/AIDS.

Effect of an abrupt change in sexual and reproductive health policy on teen birth rates in Ecuador, 2008-2017

Several countries have implemented "family-centered" abstinence-only policies for teenagers, as opposed to encouraging utilization and expansion of reproductive health services and education. Little is known, however, about the effects of these more restrictive policies on adolescent birth rates at the national level or their differential effects by race and ethnicity. The extant literature is even scarcer in low- and middle-income countries. We analyze an unexpected policy change in Ecuador that abruptly reversed course and restricted reproductive health services for teenage women in 2014. We use a canton- and time-fixed effects difference-in-differences analysis of Ecuador's 221 cantons with time-varying controls to analyze the impact of the abrupt policy change on the difference of teen (15-19 years) minus young adult (20-24 years) birth rates. In a difference-in-difference-in-differences analysis, the policy change increases birth rates by 8.5 births per 1000 women in cantons with higher indigenous concentration. Results are robust to changes in the comparison population (young adults vs. women in their late 20 s or in their early 30 s), pre-intervention control periods, population weighting, serial correlation, logarithmic model specification, adjustments for intervention year, definition of indigenous concentration, and potential delays in policy implementation.

Research Synthesis, HIV Prevention Response, and Public Health: CDC's HIV/AIDS Prevention Research Synthesis Project

OBJECTIVE

Research synthesis, through qualitative or quantitative systematic reviews, allows for integrating results of primary research to improve public health. We examined more than 2 decades of work in HIV prevention by the Centers for Disease Control and Prevention's (CDC's) HIV/AIDS Prevention Research Synthesis (PRS) Project. We describe the context and contributions of research synthesis, including systematic reviews and meta-analyses, through the experience of the PRS Project.

METHODS

We reviewed PRS Project publications and products and summarized PRS contributions from 1996 to July 2020 in 4 areas: synthesis of interventions and epidemiologic studies, synthesis methods, prevention programs, and prevention policy.

RESULTS

PRS Project publications summarized risk behaviors and effects of prevention interventions (eg, changing one's perception of risk, teaching condom negotiation skills) across populations at risk for HIV infection and intervention approaches (eg, one-on-one or group meetings) as the HIV/AIDS epidemic and science evolved. We used the PRS Project cumulative database and intervention efficacy reviews to contribute to prevention programs and policies through identification of evidence-based interventions and development of program guidance. Subject matter experts and scientific evidence informed PRS Project products and contributions, which were implemented through strategic programmatic partnerships.

CONCLUSIONS

The contributions of the PRS Project to HIV prevention and public health efforts in the United States can be credited to CDC's long-standing support of the project and its context within a federal prevention agency, where HIV programs and policies were developed and implemented. The effect of the PRS Project was likely facilitated by opportunities to directly influence program and policy because of connections with other research translation activities and program and policy decision making within CDC.

Barriers and facilitators to uptake of condoms among Filipinx transgender women and cisgender men who have sex with men: A situated socio-ecological perspective

Transgender women (TW) and cisgender men who have sex with men (cis-MSM) are disproportionately impacted by the national HIV crisis in the Philippines, where the HIV incidence has, in large part, been attributed to condomless sex. This study sought to qualitatively examine the socio-ecological factors that contribute to low condom uptake among Filipinx TW and cis-MSM communities in Manila. Between July and August 2017, we conducted semi-structured qualitative interviews with 30 TW and cis-MSM participants (n = 23 and 7, respectively). We identified structural factors described by TW and cis-MSM, and noted that they varied per situation and context of: (a) friends (e.g. as condom promoters and educators), (b) schools (e.g. lack of sex education and HIV curriculum), (c) health care facilities (e.g. availability, educational programmes, and HIV testing requirement), (d) stores (e.g. placement of condoms, distance to store, and cost), and (e) church (e.g. prohibition of condom distribution programmes, and unsupportiveness). Condom-related stigma as a social factor was pervasively present across all situation or context. Our findings support the need for multilevel condom promotion interventions that are tailored per situation or context. Future research is needed to identify factors that can be leveraged for condom promotion strategies within diverse situations.

Effects of Church-Based Parent-Child Abstinence-Only Interventions on Adolescents' Sexual Behaviors

PURPOSE

The aim of the study was to evaluate the efficacy of faith-based and nonfaith-based parent-child abstinence-only interventions in reducing sexual risk behavior among young African American adolescents.

METHODS

Randomized controlled trial recruiting 613 African American parent-adolescent dyads from urban African American Baptist churches and randomizing them to one of three parent-child interventions: faith-based abstinence-only intervention emphasizing delaying or reducing sexual intercourse drawing on Biblical scriptures; nonfaith-based abstinence-only emphasizing intervention delaying or reducing sexual intercourse without referencing scriptures; or attention-matched control intervention targeting health issues unrelated to sexual behavior. Primary outcome was the self-reported frequency of condomless sexual intercourse in the past 3 months assessed periodically through 18 months postintervention. Secondary outcomes were frequency of sexual intercourse, number of sexual partners, consistent condom use and, among sexually inexperienced adolescents, sexual debut.

RESULTS

Generalized estimating equations analyses revealed that nonfaith-based abstinence-only intervention reduced the frequency of condomless sexual intercourse, frequency of sexual intercourse, and number of sexual partners compared with the attention-matched control intervention, whereas faith-based abstinence-only intervention did not. Neither intervention affected consistent condom use or sexual debut.

CONCLUSIONS

Parent-child abstinence-only interventions can reduce condomless sexual intercourse among young African American adolescents in church settings. Linking the abstinence message to Biblical scriptures may not be efficacious.

Revealing a safer sex option to reduce HIV risk: a cluster-randomized trial in Botswana

Background

1.8 million new HIV infections occur every year, disproportionately affecting adolescent girls and young women. Abstinence-only risk avoidance approaches have had limited impact on reducing new infections. This cluster-randomized trial examines a risk reduction approach to curbing risky sex for school-going girls in Botswana.

Methods

The unit of randomization was the school (n = 229). Intervention participants received a 1-h intervention revealing a safer sex option: dating same-age partners which have 5-9x lower HIV prevalence than older partners. Primary outcomes were pregnancy as a proxy for unprotected sex and HIV. Secondary outcomes included self-reported sexual behavior. Generalized linear multilevel models with school-level robust variance for adjusted relative risk ratios were used in an intention-to-treat analysis.

Results

At a 12-month follow up, the intervention reduced pregnancy with an adjusted Relative Risk Ratio (aRRR) of .657 [95% CI .433–.997] significant at the 5% level. Effects were largest at junior school (aRRR = .575 [95% CI .394–.841]) and in rural areas (aRRR = .518 [95% CI .323–.831]), significant at the 1% level. There were no significant effects for primary school students, suggesting age of sexual debut and related mechanisms are critical factors in the intervention’s effectiveness. Moreover, baseline beliefs of which partner is riskiest mediate the magnitude of effects.

Conclusions

Information on safe sex options can change sexual behavior. The success of the intervention working across contexts will depend on various factors, such as age of sexual debut and baseline beliefs.

Towards an Integration of PrEP into a Safe Sex Ethics Framework for Men Who Have Sex with Men

The ethics of safe sex in the gay community has, for many years, been focused on debates surrounding the responsibility (or lack thereof) regarding the use of condoms to prevent HIV transmission, once the only tool available. With the development of Truvada as a pre-exposure prophylaxis (PrEP) for HIV, for the first time in the history of the HIV/AIDS epidemic there is the potential to significantly reduce the risk of HIV transmission during sex without the use of condoms (without taking into consideration 'treatment as prevention' with HIV-positive people). The introduction of PrEP necessitates a renewed discussion about the politics and ethics of safe sex for men who have sex with men (MSM). We present the arguments of authors who hold radically opposite positions with regard to the ethics of condom use by gay men, but who currently both criticize the use of PrEP. We offer a critique of their arguments and advance the position that the use of PrEP, even without condoms, can be acceptable and part of a safe sex ethics framework for MSM.

Toward Understanding How Social Factors Shaped a Behavioral Intervention on Healthier Infant Formula-Feeding

As part of a process evaluation, we explored in semi-structured interviews the experiences of 19 mothers who had taken part in a trial to reduce infant formula-milk intake and promote healthy weight gain, and reflections of three facilitators who delivered the intervention and control group protocols. Mothers appreciated the nonjudgmental support provided during the trial, after experiencing stigma and receiving limited advice on how, how much, and how often formula-milk should be given. The information mothers had previously found, printed on formula-milk tins, or provided by family, friends, and health professionals was often perceived as contradictory; the trial guidance also conflicted with social norms relating infant health positively with weight gain. For those recruited into the trial with older infants, who had already exceeded the recommendations, reducing formula-milk amounts was difficult. The findings highlight the difficulties of addressing a highly stigmatized, complex social practice with an individual, behavioral intervention approach.

The Sooner, the Worse? Association between Earlier Age of Sexual Initiation and Worse Adolescent Health and Well-being Outcomes

This cross-sectional study assesses the association between age of sexual initiation during adolescence and a selection of well-being outcomes regarding that first relationship. High-school adolescents from El Salvador (2,686) and from Peru (3,399) replied to a paper-pencil questionnaire. Those who were sexually initiated replied to several questions regarding their age at sexual initiation, condom use, satisfaction and reasons/circumstances for that sexual relationship. Approximately 19% of participants were sexually initiated (n = 1,179). After retaining participants with valid responses and with sexual initiation ages between 13 and 17, the final sample for this paper consisted of 996 sexually initiated participants (526 Salvadorians and 470 Peruvians). Multiple logistic regression analyses showed that those who initiated sex at earlier ages had worse outcomes compared to those who initiated at older ages. Specifically, they had lower odds of having used a condom, of having good memories of that experience and of having had that first relationship because they were in love. Conversely, they had higher odds of having had that first sexual relationship as a result of peer pressure (“Most of my friends already had sex”), because of partner pressure (“I was afraid to lose him/her,” “My partner told me he/she would leave me” or “I did not know how to say no to a person who insisted”), or as a consequence of different forms of impaired autonomy (“I was under the influence of alcohol or drugs” or “As a consequence of seeing sexual images”). Results show that sex at earlier ages is associated with worse adolescent health and well-being outcomes.

Prevention of HIV in Adolescent Girls and Young Women: Key to an AIDS-Free Generation

The Global Plan towards the elimination of new HIV infections among children by 2015 and keeping their mothers alive (Global Plan) has ensured that more infants in high-HIV burden countries survive childhood HIV-free. Although equal numbers of boy and girl children have survived to age 10, a gender divergence starts to emerge as they enter adolescence. Up to 3 times as many young women aged 15-24 years in eastern and southern Africa are living with HIV compared with their male peers. Further, more adolescent girls and young women are sick and/or dying from AIDS-related or HIV-related complications during pregnancy and in the postpartum period, underscoring the importance of strengthening HIV treatment and prevention services for this group. Failure to prevent HIV in adolescent girls and young women and keep them alive will reverse the infant HIV prevention and survival gains made under the Global Plan. The promising global declines in HIV infection in young women need to be strengthened to realize the goals of an AIDS-free generation. The DREAMS initiative of the United States President's Emergency Plan for AIDS Relief (PEPFAR), which specifically addresses adolescent girls and young women at highest risk of HIV acquisition, brings new hope for meeting the prevention and care needs of this important and vulnerable population through political commitment, leadership, financial and human resource investments, advocacy efforts, and a focus on the highest priority settings. Importantly, to achieve the goal of keeping mothers alive, we have to place more emphasis on access to sexual and reproductive health services that (1) include HIV prevention and treatment services for adolescent girls and young women; (2) increase male/paternal responsibility in mother and infant health; and (3) ensure a supportive social environment that enables young women to grow up into young adults who are free to graduate from high school and plan their pregnancies, ultimately entering adulthood safe, healthy, and free from HIV.

Combination HIV prevention options for young women in Africa

Although the number of new HIV infections has declined by over 30% in the past decade, the number of people who acquire HIV each year remains unacceptably high. In 2014 the Joint United Nations Programme on HIV/AIDS (UNAIDS) estimated that there were about 2 million new HIV infections. The virus continues to spread, particularly in key populations, such as men who have sex with men (MSM), transgender individuals, sex workers and people who inject drugs. In Africa, young women have the highest HIV incidence rates. Scaling up known efficacious HIV prevention strategies for these groups at high risk is therefore a high priority. HIV prevention has generally been targeted at HIV-negative individuals or in some instances, entire communities. Prevention efforts are, however, shifting from a narrow focus on HIV-uninfected persons to a continuum of prevention that includes both HIV-negative and HIV-positive individuals. Given that a single HIV prevention intervention is unlikely to be able to alter the epidemic trajectory as HIV epidemics in communities are complex and comprise a mosaic of different risk factors and different routes of transmission, there is need to provide combination prevention. Hence, a mix of behavioural, biomedical and structural HIV prevention options is likely to be needed to alter the course of the HIV epidemic. The combination of HIV prevention interventions needed will vary depending on cultural context, the population targeted and the stage of the epidemic. This paper reviews the available HIV prevention strategies for young women and discusses new HIV prevention approaches in development.

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.

Correlates of Sexually Transmitted Infections among Adolescents Attending Public High Schools, Panama, 2015

BACKGROUND

Sexually transmitted infections (STIs) are common in adolescents worldwide. Vulnerability to STIs increases with risky sexual practices. This study described the sexual practices, estimated the prevalence of STIs, and identified correlates associated with STIs among participants, enrolled in public high schools, in the District of Panama, Panama.

METHODS

A cross sectional study, using multistage cluster sampling, was conducted among participants, aged 14-18 years, enrolled in public high schools, in the District of Panama, Panama City, Panama, from August to November, 2015. Participants completed a self-administered questionnaire and provided biological samples. The samples of those reporting sexual activity (oral, vaginal, and/or anal intercourse) were tested for STIs. Odds ratios were used to identify correlates of STIs in this population.

RESULTS

A total of 592 participants were included, of whom, 60.8% reported a history of sexual activity, and 24.4% tested positive for least one STI. STIs were more common in female participants, (33.5%). Compared to those without STIs, higher proportions of those with at least one STI reported ≥3 sexual partners in their lifetime (60.0%) and current sexual activity (76.3%). In the multivariable model, correlates of STI included female participants (Adjusted Odds Ratio (AOR) = 5.8, 95% Confidence Interval (CI) 2.3-14.6) and those who engaged in sexual intercourse with casual partners (AOR = 3.0, 95% CI: 1.2-7.5).

CONCLUSIONS

We report a high STI prevalence among adolescents attending public high schools, in the District of Panama. Reported risky sexual practices were common and correlated with STIs. Female participants and those reporting sexual intercourse with casual partners were more likely test positive for at least one STI. Our study identified a need for effective interventions to curb future infections in this population.

Welfare, Liberty, and Security for All? U.S. Sex Education Policy and the 1996 Title V Section 510 of the Social Security Act

When adolescents delay (meaning they wait until after middle school) engaging in sexual intercourse, they use condoms at higher rates and have fewer sexual partners than those who have sex earlier, thus resulting in a lower risk for unintended pregnancies and sexually transmitted infections. The 1996 Section 510 of Title V of the Social Security Act (often referred to as A-H) is a policy that promotes abstinence-only-until-marriage education (AOE) within public schools. Using Stone's (2012) policy analysis framework, this article explores how A-H limits welfare, liberty, and security among adolescents due to the poor empirical outcomes of AOE policy. We recommend incorporating theory-informed comprehensive sex education in addition to theory-informed abstinence education that utilizes Fishbein and Ajzen's (2010) reasoned action model within schools in order to begin to address adolescent welfare, liberty, and security.

Who's that girl? A qualitative analysis of adolescent girls' views on factors associated with teenage pregnancies in Bolgatanga, Ghana

Background

Adolescent pregnancy remains a public health concern, with diverse serious consequences, including increased health risk for mother and child, lost opportunities for personal development, social exclusion, and low socioeconomic attainments. Especially in Africa, teenage pregnancy rates are high. It is important to find out how girls without pregnancy experience differ in their contraceptive decision-making processes as compared with their previously studied peers with pregnancy experience to address the high rate of teenage pregnancies.

Methods

We conducted semi-structured in-depth interviews with never been pregnant girls (N = 20) in Bolgatanga, Ghana, to explore the psychosocial and environmental factors influencing the sexual decision making of adolescents. Themes such as relationships, sex, pregnancy, family planning and psychosocial determinants (knowledge, attitudes, self-efficacy, norms, risk perceptions) derived from empirical studies and theories related to sexuality behavior guided the development of the interview protocol.

Results

Results showed that the girls did talk about sexuality with their mothers at home and did receive some form of sexual and reproductive health education, including the use of condoms discussions in school. Participants reported high awareness of pregnancy risk related to unprotected sex, were positive about using condoms and indicated strong self-efficacy beliefs towards negotiating condom use. The girls also formulated clear future goals, including coping plans such as ways to prevent unwanted pregnancies to reach these targets. On the other hand, their attitudes towards family planning (i.e., contraceptives other than condoms) were negative, and they hold boys responsible for buying condoms.

Conclusion

An open parental communication on sexuality issues at home, comprehensive sex education in school and attitude, self-efficacy, risk perception towards contraception, alongside with goal-setting, seem to be protective factors in adolescent girls’ pregnancy prevention efforts. These factors should be targets in future intervention programs at the individual, interpersonal, and school and community levels.

Triple combination of carbosilane dendrimers, tenofovir and maraviroc as potential microbicide to prevent HIV-1 sexual transmission

AIM

To research the synergistic activity by triple combinations of carbosilane dendrimers with tenofovir and maraviroc as topical microbicide.

METHODS

Cytotoxicity, anti-HIV-1 activity, vaginal irritation and histological analysis of triple combinations were determined. Analysis of combined effects and the median effective concentration were performed using CalcuSyn software.

RESULTS

Combinations showed a greater broad-spectrum anti-HIV-1 activity than the single-drug, and preserved this activity in acid environment or seminal fluid. The strongest combinations were G2-STE16/G2-S24P/tenofovir, G2-STE16/G2-S16/maraviroc and G2-STE16/tenofovir/maraviroc at 2:2:1, 10:10:1 10:5:1 ratios, respectively. They demonstrated strong synergistic activity profile due to the weighted average combination indices varied between 0.06 and 0.38. No irritation was detected in female BALB/c mice.

CONCLUSION

The three-drug combination increases their antiviral potency and act synergistically as potential microbicide.

Associations between early first sexual intercourse and later sexual and reproductive outcomes: a systematic review of population-based data

The assumption that early sexual debut leads to adverse outcomes has been used as justification for sexual health interventions and policies aimed at delaying sexual initiation, yet research in the area has been limited. This review identified and synthesized published literature on the association between early first sexual intercourse and later sexual/reproductive outcomes. Literature searches were conducted in Medline, Embase, PsycINFO, and Current Contents. In all, 65 citations met the selection criteria (industrialized, population-based studies). By far the most common sexual behavior to have been investigated has been sexual partners. Studies consistently reported early first intercourse to be associated with more recent, lifetime, and concurrent sexual partners. Early initiators were also more likely to participate in a wider range of sexual practices and report increased sexual satisfaction (among men). Furthermore, early first intercourse, in some studies, was shown to increase the risk of teen pregnancies, teen births, and having an abortion, while findings on STIs and contraceptive use have been mixed. These findings, however, must be interpreted with caution due to methodological problems and limitations present in the research, including a lack of consensus on what constitutes early sexual intercourse and inconsistencies and problems with analyses.

Urban African American women's explanations of recurrent chlamydia infections

OBJECTIVE

To explore reasons for the high chlamydia recurrence rate among African American (AA) urban women.

DESIGN

In this phenomenological qualitative study, young AA urban women with recurrent chlamydia were interviewed using open-ended questions guided by the conceptual framework of the health belief model (HBM).

SETTING

The study was set in three urban health clinics in Michigan.

PARTICIPANTS

Ten African American adolescents, age 15 to 19, participated.

METHODS

In face-to-face recorded interviews, participants shared their personal experiences and viewpoints on what led to their recurrent chlamydia infections. The data were transcribed and analyzed through hand coding and NVivo 8 a qualitative software package.

RESULTS

Overall, participants demonstrated significant knowledge deficits about the seriousness of chlamydia compared to other sexually transmitted infections (STIs). After reinfection, their perceived susceptibility changed: condom use was seen as beneficial and perceived barriers to condom use diminished as participants gained a new sense of empowerment.

CONCLUSION

Chlamydia infection among African American urban adolescents is nearly 3 times that of the general population. Lack of education is still a barrier to STI prevention. Participants reported a desire to receive counseling and support from the health care staff. A STI care model that includes education, counseling, and regular screening of high-risk adolescents should be considered. Further research, using the HBM or similar theoretical models, are needed to gauge the success of any planned or implemented intervention.

Programs to reduce teen pregnancy, sexually transmitted infections, and associated sexual risk behaviors: a systematic review

PURPOSE

This systematic review provides a comprehensive, updated assessment of programs with evidence of effectiveness in reducing teen pregnancy, sexually transmitted infections (STIs), or associated sexual risk behaviors.

METHODS

The review was conducted in four steps. First, multiple literature search strategies were used to identify relevant studies released from 1989 through January 2011. Second, identified studies were screened against prespecified eligibility criteria. Third, studies were assessed by teams of two trained reviewers for the quality and execution of their research designs. Fourth, for studies that passed the quality assessment, the review team extracted and analyzed information on the research design, study sample, evaluation setting, and program impacts.

RESULTS

A total of 88 studies met the review criteria for study quality and were included in the data extraction and analysis. The studies examined a range of programs delivered in diverse settings. Most studies had mixed-gender and predominately African-American research samples (70% and 51%, respectively). Randomized controlled trials accounted for the large majority (87%) of included studies. Most studies (76%) included multiple follow-ups, with sample sizes ranging from 62 to 5,244. Analysis of the study impact findings identified 31 programs with evidence of effectiveness.

CONCLUSIONS

Research conducted since the late 1980s has identified more than two dozen teen pregnancy and STI prevention programs with evidence of effectiveness. Key strengths of this research are the large number of randomized controlled trials, the common use of multiple follow-up periods, and attention to a broad range of programs delivered in diverse settings. Two main gaps are a lack of replication studies and the need for more research on Latino youth and other high-risk populations. In addressing these gaps, researchers must overcome common limitations in study design, analysis, and reporting that have negatively affected prior research.

I want to hold your hand: abstinence curricula, bioethics, and the silencing of desire

The abstinence approach to sex education remains influential despite its demonstrated ineffectiveness. One bill forbids the "promotion" of "gateway sexual activity," while requiring outright condemnation of "non-abstinence," defined so loosely as to plausibly include handholding. Bioethics seldom (if ever) contributes to sex-ed debates, yet exploring the pivotal role of medical discourse reveals the need for bioethical intervention. Sex-ed debates revolve around a theory of human flourishing based on heteronormative temporality, a developmental teleology ensuring the transmission of various supposed social goods through heterosexual marriage (Halberstam, 2005). Heteronormative temporality also constitutes a moralized discourse in which the values of health and presumed certainties of medicine serve to justify conservative religious dictates that otherwise would appear controversial as the basis for public policy. Overall, this analysis explores how moralized medical discourses compound existing injustices, while suggesting bioethics' potential contributions to moral and political analysis of sex-ed policies.

What do patients think about HIV mass screening in France? A qualitative study

Background

Since 2009, HIV mass screening of the 15–70-year-old general population in low-risk situations has been recommended in France. This, not yet implemented, untargeted screening would be cost-effective with a positive impact on public health. No previous studies had interrogated primary care patients about it. This study aimed at exploring perceptions of patients attending general practitioner’s on HIV mass screening and at identifying barriers to its implementation.

Methods

We conducted a qualitative study through semi-structured individual interviews. Participants were recruited according to age, gender and location of their physician’s practice. Data analysis was based on triangulation by two researchers.

Results

Twenty-four interviews were necessary to obtain data saturation. HIV transmission was mostly associated with sexual intercourse; main barriers stemming from the screening were related to sexuality, often seen as questioning spouse’s faithfulness. It could interfere with religiosity, implying an upsetting perception of sexuality among the elderly. Patients’ beliefs and perceptions regarding HIV/AIDS, the fear to be screened and difficulties to talk about sexuality were other barriers.

Conclusion

To our knowledge, no studies had previously interrogated primary care patients about barriers to HIV mass screening in France. Although relevance of this untargeted screening is debated in France, our results could be helpful to a better understanding of patients’ attitudes toward this and to an outstanding contribution to reduce the number of new cases of HIV contamination.

Examining interest in secondary abstinence among young African American females at risk for HIV or STIs

Sexually active African American females are at increased risk for acquiring HIV or STIs. However, some reduce their risk by abstaining from sex for various periods of time following initiation, a practice known as secondary abstinence. Although this may be a valuable mechanism for reducing HIV or STI rates in this population, little is known about those interested in secondary abstinence. Baseline data were obtained from a sample of African American adolescent females, ages 14-20 years, prior to participation in an HIV-risk reduction intervention trial (N = 701). Differences in individual-level and interpersonal-level factors, as well as sociodemographic variables were examined between participants who reported strong interest in secondary abstinence and those who did not. 144 (20.5%) participants reported strong interest in secondary abstinence. Young women with strong interest in abstinence had higher odds of reporting a history of STIs and feeling negative emotions following sex because of their religious beliefs. They also had higher odds of believing their partner may be interested in abstaining and being less invested in their relationship with their main partner. Additionally, adolescents reported less interpersonal stress and more social support. African American females who are interested in practicing secondary abstinence and those who are not differ in their sexual health education needs. Findings from this study characterizing young women interested in secondary abstinence can help researchers provide more targeted health education by identifying those who may be more responsive to abstinence-promoting messages.

Consequences of sex education on teen and young adult sexual behaviors and outcomes

PURPOSE

This study examined whether formal sex education is associated with sexual health behaviors and outcomes using recent nationally representative survey data.

METHODS

Data used were from 4,691 male and female individuals aged 15-24 years from the 2006-2008 National Survey of Family Growth. Weighted bivariate and multivariate analyses were conducted by gender, estimating the associations of sex education by type (only abstinence, abstinence and birth control, or neither) before first sexual intercourse, and sexual behaviors and outcomes.

RESULTS

Receipt of sex education, regardless of type, was associated with delays in first sex for both genders, as compared with receiving no sex education. Respondents receiving instruction about abstinence and birth control were significantly more likely at first sex to use any contraception (odds ratio [OR] = 1.73, females; OR = 1.91, males) or a condom (OR = 1.69, females; OR = 1.90, males), and less likely to have an age-discrepant partner (OR = .67, females; OR = .48, males). Receipt of only abstinence education was not statistically distinguishable in most models from receipt of either both or neither topics. Among female subjects, condom use at first sex was significantly more likely among those receiving instruction in both topics as compared with only abstinence education. The associations between sex education and all longer-term outcomes were mediated by older age at first sex.

CONCLUSIONS

Sex education about abstinence and birth control was associated with healthier sexual behaviors and outcomes as compared with no instruction. The protective influence of sex education is not limited to if or when to have sex, but extends to issues of contraception, partner selection, and reproductive health outcomes.

A quasi-experimental evaluation of an HIV prevention programme by peer education in the Anglican Church of the Western Cape, South Africa

INTRODUCTION

Religion is important in most African communities, but faith-based HIV prevention programmes are infrequent and very rarely evaluated.

OBJECTIVE

The aim of this study was to evaluate the effectiveness of a church-based peer education HIV prevention programme that focused on youth.

DESIGN

A quasi-experimental study design compared non-randomly chosen intervention and control groups.

SETTING

This study was conducted in the Cape Town Diocese of the Anglican Church of Southern Africa.

PARTICIPANTS

The intervention group of 176 teenagers was selected from youth groups at 14 churches and the control group of 92 from youth groups at 17 churches. Intervention and control churches were chosen to be as similar as possible to decrease confounding.

INTERVENTION

The intervention was a 20-session peer education programme (Fikelela: Agents of Change) aimed at changing risky sexual behaviour among youth (aged 12-19 years). Three workshops were also held with parents.

PRIMARY AND SECONDARY OUTCOME MEASURES

The main outcome measures were changes in age of sexual debut, secondary abstinence, condom use and numbers of partners.

RESULTS

The programme was successful at increasing condom usage (condom use score 3.5 vs 2.1; p=0.02), OR 6.7 (95% CI 1.1 to 40.7), and postponing sexual debut (11.9% vs 21.4%; p=0.04) absolute difference 9.5%. There was no difference in secondary abstinence (14.6% vs 12.5%; p=0.25) or with the number of partners (mean 1.7 vs 1.4; p=0.67) and OR 2.2 (95% CI 0.7 to 7.4).

CONCLUSION

An initial exploratory quasi-experimental evaluation of the Agents of Change peer education programme in a church-based context found that the age of sexual debut and condom usage was significantly increased. The study demonstrated the potential of faith-based peer education among youth to make a contribution to HIV prevention in Africa. Further evaluation of the effectiveness of the programme is, however, required before widespread implementation can be recommended.

Can peer education make a difference? Evaluation of a South African adolescent peer education program to promote sexual and reproductive health

Peer education is popular both with governments and with young people. The purpose of this quasi-experimental study was to evaluate the effectiveness of a government-led peer education program on the self-reported sexual health behavior and related psychosocial outcomes of adolescent students in public high schools in the Western Cape of South Africa. Grade 10 students (n = 3934), at 30 public high schools (15 intervention, 15 comparison) were recruited to the study. In the intervention schools, peer educators were recruited and trained to provide information and support to their fellow students. Sexual health behaviors and related psychosocial outcomes of students were measured at baseline and at follow up 18 months later. Comparisons were made between those in the intervention and comparison group schools. We were unable to detect a significant difference in the age of sexual debut, use of condoms at last sex, goal orientation, decision-making or future orientation for students in the intervention group as compared to students in the comparison group. The findings suggest that the peer education program was not effective in reducing the age of sexual debut or condom use. Issues around the implementation of the program suggested that this was sub-optimal. Governments who advocate widespread use of peer education as an approach need to recognise barriers to implementation and ensure ongoing monitoring and evaluation of effectiveness and cost effectiveness.

Mathematical models for the study of HIV spread and control amongst men who have sex with men

For a quarter of century, mathematical models have been used to study the spread and control of HIV amongst men who have sex with men (MSM). We searched MEDLINE and EMBASE databases up to the end of 2010 and reviewed this literature to summarise the methodologies used, key model developments, and the recommended strategies for HIV control amongst MSM. Of 742 studies identified, 127 studies met the inclusion criteria. Most studies employed deterministic modelling methods (80%). Over time we saw an increase in model complexity regarding antiretroviral therapy (ART), and a corresponding decrease in complexity regarding sexual behaviours. Formal estimation of model parameters was carried out in only a small proportion of the studies (22%) while model validation was considered by an even smaller proportion (17%), somewhat reducing confidence in the findings from the studies. Nonetheless, a number of common conclusions emerged, including (1) identification of the importance of assumptions regarding changes in infectivity and sexual contact rates on the impact of ART on HIV incidence, that subsequently led to empirical studies to gather these data, and (2) recommendation that multiple strategies would be required for effective HIV control amongst MSM. The role of mathematical models in studying epidemics is clear, and the lack of formal inference and validation highlights the need for further developments in this area. Improved methodologies for parameter estimation and systematic sensitivity analysis will help generate predictions that more fully express uncertainty, allowing better informed decision making in public health.

Obstetrician-gynecologists' beliefs about safe-sex and abstinence counseling

OBJECTIVE

To examine obstetrician-gynecologists' beliefs about safe-sex and abstinence counseling.

METHODS

Between October 2008 and January 2009, a survey was mailed to a national randomized sample of 1800 practicing US obstetrician-gynecologists. Study variables were agreement with 2 statements. (1) "If physicians counsel patients about safe-sex practices, the patients will be less likely to engage in risky sexual behaviors". (2) "If physicians counsel patients about abstinence, the patients will be much less likely to engage in sexual activity". Covariates included demographic, clinical, and religious characteristics of the physician.

RESULTS

The response rate was 66% (1154/1760 eligible physicians). Most respondents somewhat (62%) or strongly (25%) agreed that counseling patients about safe-sex practices makes patients less likely to engage in risky sexual behaviors. Fewer agreed strongly (3%) or somewhat (28%) that counseling patients about abstinence makes patients less likely to engage in sexual activity. The belief that safe-sex counseling reduces risky behaviors was less common among males (odds ratio [OR] 0.6) and more common among immigrants (OR 2.0). Religious physicians were more likely to believe that abstinence counseling reduces sexual activity (OR 2.2-5.3).

CONCLUSIONS

Most obstetrician-gynecologists believed that counseling about safe sex is effective, and a significant minority endorsed abstinence counseling.

Perceptions about sexual abstinence and knowledge of HIV/AIDS prevention among in-school adolescents in a western Nigerian city

BACKGROUND

Young people are becoming increasingly exposed to the risk of HIV infection. According to the 2008 HIV/Syphilis sentinel survey in Nigeria, 3.3% of young people aged 15-19 years are infected. Primary prevention especially abstinence, remains one of the most realistic interventions for reducing further spread of the virus. However, the adoption of sexual abstinence as a prevention strategy among adolescents remains low and factors influencing its practice among urban young people in Nigeria are relatively unknown. The aim of the study was to document the sexual abstinence behaviour of in-school adolescents, the factors influencing or obstructing abstinence, and knowledge of HIV and AIDS in Ibadan, South-West Nigeria.

METHODS

The study was a descriptive cross-sectional survey of students in Ibadan South-West Local Government Area. A total of 420 respondents (52% males and 48% females), selected through a multistage sampling technique, completed a semi-structured questionnaire. This was supplemented with eight focus group discussions (FGDs) which had an average of 9 respondents within the 10 and 19 years age group. The data from the FGDs were transcribed and summarized manually while the quantitative data was analyzed using the Statistical Package for the Social Sciences to generate frequencies, cross tabulations of variables and logistic regression analysis.

RESULTS

Twelve percent of the entire sample had ever had sex. Overall, knowledge of HIV transmission and prevention was high and most respondents favoured the promotion of abstinence as an HIV prevention strategy. A smaller proportion of male respondents (79%) abstained compared with the females (98%). Major predictors of sexual abstinence were being a female, not having a boyfriend or girl friend, not using alcohol and having a positive attitude towards abstinence (P < 0.05).Sexual abstinence was also significantly associated with perceived self efficacy to refuse sex and negative perception of peers who engage in sexual behaviours (P < 0.05). Majority of the FGD discussants suggested the involvement of parents, media, schools, faith-based institutions and non governmental organizations in promoting the adoption of abstinence.

CONCLUSIONS

The sexual abstinence behaviour of young persons is influenced by multiple factors and should be considered in determining the effectiveness of interventions targeting this behaviour. Coherent sexuality education interventions to promote the adoption of abstinence among young people are urgently needed.

Interventions for encouraging sexual behaviours intended to prevent cervical cancer

BACKGROUND

Human papillomavirus (HPV) is the key risk factor for cervical cancer. Continuing high rates of HPV and other sexually transmitted infections (STIs) in young people demonstrate the need for effective behavioural interventions.

OBJECTIVES

To assess the effectiveness of behavioural interventions for young women to encourage safer sexual behaviours to prevent transmission of STIs (including HPV) and cervical cancer.

SEARCH STRATEGY

Systematic literature searches were performed on the following databases: Cochrane Central Register of Controlled Trials (CENTRAL Issue 4, 2009) Cochrane Gynaecological Cancer Review Group (CGCRG) Specialised Register, MEDLINE, EMBASE, CINAHL, PsychINFO, Social Science Citation Index and Trials Register of Promoting Health Interventions (TRoPHI) up to the end of 2009. All references were screened for inclusion against selection criteria.

SELECTION CRITERIA

Randomised controlled trials (RCTs) of behavioural interventions for young women up to the age of 25 years that included, amongst other things, information provision about the transmission and prevention of STIs. Trials had to measure behavioural outcomes (e.g. condom use) and/or biological outcomes (e.g. incidence of STIs, cervical cancer).

DATA COLLECTION AND ANALYSIS

A narrative synthesis was conducted. Meta-analysis was not considered appropriate due to heterogeneity between the interventions and trial populations.

MAIN RESULTS

A total of 5271 references were screened and of these 23 RCTs met the inclusion criteria. Most were conducted in the USA and in health-care clinics (e.g. family planning).The majority of interventions provided information about STIs and taught safer sex skills (e.g. communication), occasionally supplemented with provision of resources (e.g. free sexual health services). They were heterogeneous in duration, contact time, provider, behavioural aims and outcomes. A variety of STIs were addressed including HIV and chlamydia. None of the trials explicitly mentioned HPV or cervical cancer prevention.Statistically significant effects for behavioural outcomes (e.g. increasing condom use) were common, though not universal and varied according to the type of outcome. There were no statistically significant effects of abstaining from or reducing sexual activity. There were few statistically significant effects on biological (STI) outcomes. Considerable uncertainty exists in the risk of bias due to incomplete or ambiguous reporting.

AUTHORS' CONCLUSIONS

Behavioural interventions for young women which aim to promote sexual behaviours protective of STI transmission can be effective, primarily at encouraging condom use. Future evaluations should include a greater focus on HPV and its link to cervical cancer, with long-term follow-up to assess impact on behaviour change, rates of HPV infection and progression to cervical cancer. Studies should use an RCT design where possible with integral process evaluation and cost-effectiveness analysis where appropriate. Given the predominance of USA studies in this systematic review evaluations conducted in other countries would be particularly useful.

The evolving HIV/AIDS response and the urgent tasks ahead

AIDS continues to outpace the science, financing, prevention, and treatment efforts of the past quarter-century. There have been different epochs along the evolutionary timeline of the global AIDS response, from the discovery of HIV to the threat posed by the current economic crisis. This timeline serves as a reference to how we have arrived where we are today, in the hope that understanding our past will help us set the course for a more efficient and effective future response.

How do adolescents view health? Implications for state health policy

OBJECTIVES

Policy-makers rarely consult adolescents during development of health policies. However, perspectives of adolescents on health can inform public health policies and programs. As part of the development of an Indiana state plan for adolescent health, we used qualitative methods to describe adolescents' "emic" views of health, and discuss implications for a state health policy for youth.

PATIENTS AND METHODS

We conducted eight adolescent focus groups in geographically and culturally diverse regions of Indiana. Each group was audio-recorded, transcribed, and analyzed using qualitative methods.

RESULTS

Participants described health as a shared responsibility between adolescents and adults in their lives. They identified a key role for supportive adults in initiating and maintaining health behaviors. Physical, financial, and informational environments could support or hinder healthy behaviors and outcomes. Although adolescents' descriptions of physical health and risk behaviors were similar to adult formulations, they described mental health as "stress and fatigue," an interaction between the adolescent and their environment, rather than depression and anxiety which are considered to be individual pathologies. Respect for decision-making capacity, seeking adolescent input, and providing harm reduction messages were identified as particularly important.

CONCLUSIONS

Adolescent's perception of health can inform policies and programs, and should be sought before the development of health policies.

Is 80% a passing grade? Meanings attached to condom use in an abstinence-plus HIV prevention programme in South Africa

This study represents the first qualitative exploration of how condoms are perceived by at-risk youth, their parents, their teachers and HIV prevention programme staff in an abstinence-plus HIV prevention programme. Behavioural interventions for HIV prevention with youth may be divided into three categories, each with a different approach to condoms: abstinence-only, abstinence-plus and comprehensive approaches. Research has highlighted the limitations of abstinence-only approaches and the emergence of early support for abstinence-plus interventions as HIV prevention strategies. Furthermore, research consistently demonstrates that condoms are socially mediated, reflecting diverse norms. However, there is a gap in the literature in terms of how condom use is framed, understood and represented by those delivering and receiving an abstinence-plus programme. This is critically important because advocates of a comprehensive approach to HIV prevention have flagged concern with the degree to which abstinence-plus programming may undermine confidence in condom use. Therefore, this study analyses meanings attached to condom use by stakeholders in an abstinence-plus HIV prevention programme in South Africa. Results demonstrate diverse meanings attached to condom use, including: condoms as second best to abstinence; condoms as a gendered response to HIV; condoms as a source of mockery; condoms as futile in a high-prevalence setting; condoms as part of conspiracy beliefs along racial and colonial lines; and, condoms as popular in HIV prevention because they can be counted. These findings have particular bearing for abstinence-plus HIV prevention programmes, which face the double challenge of (1) engaging with condom promotion in a way that takes into account their diverse social meanings, and (2) promoting condoms within their hierarchical framework of options in a way that does not inadvertently discourage their use.

The unwillingness of future U.S. physicians to limit adolescent prevention counseling to abstinence-only messages

OBJECTIVES

Open family planning discussions are essential, though until very recently curtailed in the U.S., yet no study has evaluated future physicians' willingness to curtail their counseling.

DESIGN

Senior medical students at 16 U.S. schools (n=2316, response rate=80.3%) were surveyed on their agreement with: "I am willing to limit the sexually transmissible disease (STD) prevention counseling I do for unmarried teens to 'abstinence-only' messages."

RESULTS

Among seniors, <10% agreed to limit their counseling for unmarried teens to "abstinence-only" messages. Male gender, stronger religious identity, and more conservatism were most strongly associated with willingness to limit counseling.

CONCLUSIONS

Most senior U.S. medical students were not willing to limit the STD prevention counseling they provide. As the new U.S. (and other) governments re-evaluate policies, it is wise that they are reconsidering policies that ran counter to the beliefs of its future physician workforce.

Advocating for schools to provide effective HIV and sexuality education: a case study in how social service organizations working in coalition can (and should) affect sustained policy change

Advocates believed that to slow an expanding HIV/ AIDS epidemic in Washington, D.C., a local effort could ensure that HIV prevention was brought to scale. Schools were chosen as the focus and a new coalition advocated for the city government to pass new academic standards for health education. HIV and sex education policies had not been revised in more than 12 years and HIV education in D.C. public schools varied greatly in quality. Metro TeenAIDS (MTA), a traditional social service organization with no real history of advocacy work, reached only 10% of D.C. adolescents with critical HIV/AIDS prevention information. Clearly, to make a sustained impact, system change was necessary. After deciding to pursue a campaign focused on updating health education policy and creating standards, MTA convened a variety of reproductive health, adolescent medicine, and other organizations to establish the DC Healthy Youth Coalition. The Coalition used three complementary strategies to achieve campaign goals: mobilizing grassroots community support, involving parents in the discussion, and educating city leaders. By building an alliance of social service organizations and influencing critical public policy, the coalition ensured that new educational standards were passed.

Changes in sexual behaviours: from secular trends to public health policies

OBJECTIVE

To explore the relative contribution of secular trends and public health policies to changes in sexual behaviour.

DESIGN

Three random probability surveys of the sexual behaviour of people aged 18-69 years were conducted in 1970, 1992 and 2006 in France.

METHODS

Data of the 2006 survey (n = 12,364) were compared with those from two surveys carried out in 1970 (n = 2625) and 1992 (n = 20,055).

RESULTS

Over the last decades, median age at first intercourse has decreased by 4 years for women (22.0 in the 1930s vs. 17.6 in the 2000s) and 1 year for men (18.1 vs. 17.2). Lifetime number of sexual partners increased for women (1.8 in 1970 vs. 4.4 in 2006), but not for men (11.8 vs. 11.6). At the same time, the proportion of respondents, especially women, who reported nonpenetrative sexual practices and considered sexual intercourse essential to well being was on the increase. These changes are mainly attributed to an increase in women's social status. A marked increase in condom use was observed following the first AIDS/HIV prevention campaigns in the 1980s.

CONCLUSION

Public health interventions that are synergistic with trends in social norms are likely to be more effective than those that run counter to them. In France, sexual health and HIV prevention policies aimed at harm limitation appear to have chimed with secular trends. The evidence of greater diversification of sexual practices offers potential to increase the range of safer sex messages used in public health interventions.

Efficacy of a theory-based abstinence-only intervention over 24 months: a randomized controlled trial with young adolescents

OBJECTIVE

To evaluate the efficacy of an abstinence-only intervention in preventing sexual involvement in young adolescents.

DESIGN

Randomized controlled trial.

SETTING

Urban public schools.

PARTICIPANTS

A total of 662 African American students in grades 6 and 7.

INTERVENTIONS

An 8-hour abstinence-only intervention targeted reduced sexual intercourse; an 8-hour safer sex-only intervention targeted increased condom use; 8-hour and 12-hour comprehensive interventions targeted sexual intercourse and condom use; and an 8-hour health-promotion control intervention targeted health issues unrelated to sexual behavior. Participants also were randomized to receive or not receive an intervention maintenance program to extend intervention efficacy.

OUTCOME MEASURES

The primary outcome was self-report of ever having sexual intercourse by the 24-month follow-up. Secondary outcomes were other sexual behaviors.

RESULTS

The participants' mean age was 12.2 years; 53.5% were girls; and 84.4% were still enrolled at 24 months. Abstinence-only intervention reduced sexual initiation (risk ratio [RR], 0.67; 95% confidence interval [CI], 0.48-0.96). The model-estimated probability of ever having sexual intercourse by the 24-month follow-up was 33.5% in the abstinence-only intervention and 48.5% in the control group. Fewer abstinence-only intervention participants (20.6%) than control participants (29.0%) reported having coitus in the previous 3 months during the follow-up period (RR, 0.94; 95% CI, 0.90-0.99). Abstinence-only intervention did not affect condom use. The 8-hour (RR, 0.96; 95% CI, 0.92-1.00) and 12-hour comprehensive (RR, 0.95; 95% CI, 0.91-0.99) interventions reduced reports of having multiple partners compared with the control group. No other differences between interventions and controls were significant.

CONCLUSION

Theory-based abstinence-only interventions may have an important role in preventing adolescent sexual involvement.

TRIAL REGISTRATION

A lectin isolated from bananas is a potent inhibitor of HIV replication

BanLec is a jacalin-related lectin isolated from the fruit of bananas, Musa acuminata. This lectin binds to high mannose carbohydrate structures, including those found on viruses containing glycosylated envelope proteins such as human immunodeficiency virus type-1 (HIV-1). Therefore, we hypothesized that BanLec might inhibit HIV-1 through binding of the glycosylated HIV-1 envelope protein, gp120. We determined that BanLec inhibits primary and laboratory-adapted HIV-1 isolates of different tropisms and subtypes. BanLec possesses potent anti-HIV activity, with IC(50) values in the low nanomolar to picomolar range. The mechanism for BanLec-mediated antiviral activity was investigated by determining if this lectin can directly bind the HIV-1 envelope protein and block entry of the virus into the cell. An enzyme-linked immunosorbent assay confirmed direct binding of BanLec to gp120 and indicated that BanLec can recognize the high mannose structures that are recognized by the monoclonal antibody 2G12. Furthermore, BanLec is able to block HIV-1 cellular entry as indicated by temperature-sensitive viral entry studies and by the decreased levels of the strong-stop product of early reverse transcription seen in the presence of BanLec. Thus, our data indicate that BanLec inhibits HIV-1 infection by binding to the glycosylated viral envelope and blocking cellular entry. The relative anti-HIV activity of BanLec compared favorably to other anti-HIV lectins, such as snowdrop lectin and Griffithsin, and to T-20 and maraviroc, two anti-HIV drugs currently in clinical use. Based on these results, BanLec is a potential component for an anti-viral microbicide that could be used to prevent the sexual transmission of HIV-1.
