Abstract
INTRODUCTION Sexual activity is an essential human need and an important predictor of other aspects of human life. A literature review was conducted to investigate whether sexual abstinence in young and middle-aged men is generally considered a deliberate, healthy behavior and whether it has other causes and consequences. AIM To review the prevalence and factors associated with sexual abstinence in young (10-24 years) and middle-aged (25-59 years) men. METHODS Studies were retrieved from Science Direct, PubMed, and EBSCOhost published from 2008 to 2019. The selection criteria were original population- or community-based articles, published in the English language, on sexual abstinence, and in young and middle-aged men. MAIN OUTCOME MEASURE This article reviewed the literature on the proportions of and factors associated with sexual abstinence in young and middle-aged men. RESULTS A total of 13,154 studies were retrieved, from which data were extracted for 37 population- or community-based studies. The prevalence of sexual abstinence varied from 0% to 83.6% in men younger than 60 years. The prevalence of primary sexual abstinence was 3.4%-83.3% for young men and 12.5%-15.5% for middle-aged men. The prevalence of secondary abstinence for young men ranged from 1.3% to 83.6%, while for middle-aged men, it was from 1.2% to 67.7%. The prevalence of sexual abstinence decreased with increasing age in young men but increased with increasing age in middle-aged men. The significant factors reported were age, single status, poor relationships, low socioeconomic status, sex education, religious practices, caring and monitoring parents, and not using alcohol, cigarettes, or drugs. Although the variations in findings from different studies can be explained by different regions and cultures, the information cannot be generalized worldwide because of a lack of studies in Asian and Australian populations. CLINICAL IMPLICATIONS The studies on sexual abstinence in the future should use a consistent and standard definition, cover all sexual behaviors, and investigate all related factors. STRENGTH & LIMITATIONS The restricted timeframe (2008-2019), English language, availability of full text, and variability in definition and time duration may be the sources of bias. CONCLUSION Young men had higher proportions of sexual abstinence than middle-aged men, and age, unavailability of a partner, lower educational levels, low socioeconomic status, conservative and religious conditions, and no or less knowledge about sexually transmitted infections were common predictors of sexual abstinence in most of the men. Although determinants of sexual abstinence were identified, further investigation of biological factors in men younger than 60 years is needed. Irfan M, Hussain NHN, Noor NM, et al.

Abstract
School-based programs have been a mainstay of youth pregnancy prevention efforts in the USA. We conducted a systematic review and meta-analysis to assess their effectiveness. Eligible studies evaluated the effect on pregnancy rates of programs delivered in elementary, middle, or high schools in the USA and Canada, published between January 1985 and September 2016. The primary outcome was pregnancy; secondary outcomes were delay in sexual initiation, condom use, and oral contraception use. Randomized controlled trials (RCTs) and non-RCTs with comparator groups were eligible. We developed a comprehensive search strategy, applied to major bibliographic databases, article bibliographies, gray literature, and contact with authors. We calculated risk ratios (RR) with 95% confidence intervals (CI) for each outcome and pooled data in random effects meta-analysis. We used Grading of Recommendations Assessment, Development and Evaluation (GRADE) to assess evidence quality. Ten RCTs and 11 non-RCTs conducted from 1984 to 2016 yielded 30 unique pooled comparisons for pregnancy, of which 24 were not statistically significant. Six showed statistically significant changes in pregnancy rates: two with increased risk (RR 1.30, 95% CI 1.02-1.65; and RR 1.39, 95% CI 1.10-1.75) and four with decreased risk ranging from RR 0.56, 95% CI 0.41-0.77, to RR 0.75, 95% CI 0.58-0.96. All studies were at high risk of bias, and the quality of evidence was low or very low. Identified evidence indicated no consistent difference in rates of pregnancies between intervention recipients and controls.

Abstract
We systematically reviewed the literature to assess the effectiveness of school-based programs to prevent HIV and other sexually transmitted infections (STI) among adolescents in the USA. We searched six databases including PubMed for studies published through May 2017. Eligible studies included youth ages 10-19 years and assessed any school-based programs in the USA that reported changes in HIV/STI incidence or testing. We used Cochrane tool to assess the risk of bias and GRADE to determine the evidence quality for each outcome. Three RCTs and six non-RCTs, describing seven interventions, met study inclusion criteria. No study reported changes in HIV incidence or prevalence. One comprehensive intervention, assessed in a non-RCT and delivered to pre-teens, reduced STI incidence into adulthood (RR 0.36, 95% CI 0.23-0.56). A non-RCT examining chlamydia and gonorrhea incidence before and after a condom availability program found a significant effect at the city level among young men 3 years later (RR 0.43, 95% CI 0.23-0.80). The remaining four interventions found no effect. The effect on STI prevalence was also not significant (pooled RR 0.83 from two non-RCTs, RR 0.70 from one RCT). Only one non-RCT showed an increase in HIV testing (RR 3.19, 95% CI 1.24-8.24). The quality of evidence for all outcomes was very low. Studies, including the RCTs, were of low methodological quality and had mixed findings, thus offering no persuasive evidence for the effectiveness of school-based programs. The most effective intervention spanned 6 years, was a social development-based intervention with multiple components, rather than a sex education program, and started in first grade.

Abstract
This study assesses the relationship between pornography consumption and support for sex education in public schools among adults in the United States. Goals were theoretical and applied. At the theoretical level, conditional process analyses are needed to further evaluate the predictions of the primary theory applied to pornography and social influence, the sexual script acquisition, activation, application model (3AM) of sexual media socialization. At the applied level, themes in pornography are most often associated with socialization outcomes that are a threat to the public health. In certain instances, however, pornography may socialize its users in ways that lead to health-promoting attitudes. An increased likelihood of support for sex education among youth may be one such example. Probabilistic national survey data gathered between 1988 and 2016 from 16 unique samples were utilized. A moderated-mediation path analysis indicated that pornography consumption was associated with support for sex education through more acceptance of teenage sex, but that this indirect effect (IE) was moderated by religiosity. Specifically, as religiosity decreased, the magnitude of the IE increased. These results are consistent with 3AM tenets about the role of sexual scripts in mass media socialization and factors that increase the likelihood of sexual scripting effects.

Abstract
ISSUE ADDRESSED Young people have a high burden of sexual and reproductive health (SRH) problems, and it is important to reach this group through health promotion initiatives. We conducted a systematic review of reviews to identify successful elements of health promotion programs for improving SRH of young people. METHODS We identified and collated systematic reviews published in 2005-2015 which focused on young people (10-24 years), reported on SRH outcomes (pregnancy, sexually transmissible infections, condoms/contraceptive use, risky sexual behaviour, sexual healthcare access or intimate partner violence), and included primary studies predominantly conducted in high-income countries. This report focuses on features of successful SRH programs identified in the interpretation and discussion of included systematic reviews. RESULTS We identified 66 systematic reviews, of which 37 reported on program features which were anecdotally or statistically associated with improved program effectiveness and success. Common features of effective interventions were: longer term or repeated implementation; multi-setting and multi-component; parental involvement; culturally/gender/age appropriate; and inclusion of skills-building. SO WHAT?: There is marked consistency of features improving SRH program effectiveness for young people despite the wide variation in interventions reviewed. There is a need to better implement this knowledge in future programs, and our findings provide useful guidance for optimising the design of SRH interventions for young people.

Abstract
BACKGROUND School-based sexual and reproductive health programmes are widely accepted as an approach to reducing high-risk sexual behaviour among adolescents. Many studies and systematic reviews have concentrated on measuring effects on knowledge or self-reported behaviour rather than biological outcomes, such as pregnancy or prevalence of sexually transmitted infections (STIs). OBJECTIVES To evaluate the effects of school-based sexual and reproductive health programmes on sexually transmitted infections (such as HIV, herpes simplex virus, and syphilis), and pregnancy among adolescents. SEARCH METHODS We searched MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials (CENTRAL) for published peer-reviewed journal articles; and ClinicalTrials.gov and the World Health Organization's (WHO) International Clinical Trials Registry Platform for prospective trials; AIDS Educaton and Global Information System (AEGIS) and National Library of Medicine (NLM) gateway for conference presentations; and the Centers for Disease Control and Prevention (CDC), UNAIDS, the WHO and the National Health Service (NHS) centre for Reviews and Dissemination (CRD) websites from 1990 to 7 April 2016. We handsearched the reference lists of all relevant papers. SELECTION CRITERIA We included randomized controlled trials (RCTs), both individually randomized and cluster-randomized, that evaluated school-based programmes aimed at improving the sexual and reproductive health of adolescents. DATA COLLECTION AND ANALYSIS Two review authors independently assessed trials for inclusion, evaluated risk of bias, and extracted data. When appropriate, we obtained summary measures of treatment effect through a random-effects meta-analysis and we reported them using risk ratios (RR) with 95% confidence intervals (CIs). We assessed the certainty of the evidence using the GRADE approach. MAIN RESULTS We included eight cluster-RCTs that enrolled 55,157 participants. Five trials were conducted in sub-Saharan Africa (Malawi, South Africa, Tanzania, Zimbabwe, and Kenya), one in Latin America (Chile), and two in Europe (England and Scotland). Sexual and reproductive health educational programmesSix trials evaluated school-based educational interventions.In these trials, the educational programmes evaluated had no demonstrable effect on the prevalence of HIV (RR 1.03, 95% CI 0.80 to 1.32, three trials; 14,163 participants; low certainty evidence), or other STIs (herpes simplex virus prevalence: RR 1.04, 95% CI 0.94 to 1.15; three trials, 17,445 participants; moderate certainty evidence; syphilis prevalence: RR 0.81, 95% CI 0.47 to 1.39; one trial, 6977 participants; low certainty evidence). There was also no apparent effect on the number of young women who were pregnant at the end of the trial (RR 0.99, 95% CI 0.84 to 1.16; three trials, 8280 participants; moderate certainty evidence). Material or monetary incentive-based programmes to promote school attendanceTwo trials evaluated incentive-based programmes to promote school attendance.In these two trials, the incentives used had no demonstrable effect on HIV prevalence (RR 1.23, 95% CI 0.51 to 2.96; two trials, 3805 participants; low certainty evidence). Compared to controls, the prevalence of herpes simplex virus infection was lower in young women receiving a monthly cash incentive to stay in school (RR 0.30, 95% CI 0.11 to 0.85), but not in young people given free school uniforms (Data not pooled, two trials, 7229 participants; very low certainty evidence). One trial evaluated the effects on syphilis and the prevalence was too low to detect or exclude effects confidently (RR 0.41, 95% CI 0.05 to 3.27; one trial, 1291 participants; very low certainty evidence). However, the number of young women who were pregnant at the end of the trial was lower among those who received incentives (RR 0.76, 95% CI 0.58 to 0.99; two trials, 4200 participants; low certainty evidence). Combined educational and incentive-based programmesThe single trial that evaluated free school uniforms also included a trial arm in which participants received both uniforms and a programme of sexual and reproductive education. In this trial arm herpes simplex virus infection was reduced (RR 0.82, 95% CI 0.68 to 0.99; one trial, 5899 participants; low certainty evidence), predominantly in young women, but no effect was detected for HIV or pregnancy (low certainty evidence). AUTHORS' CONCLUSIONS There is a continued need to provide health services to adolescents that include contraceptive choices and condoms and that involve them in the design of services. Schools may be a good place in which to provide these services. There is little evidence that educational curriculum-based programmes alone are effective in improving sexual and reproductive health outcomes for adolescents. Incentive-based interventions that focus on keeping young people in secondary school may reduce adolescent pregnancy but further trials are needed to confirm this.

Abstract
OBJECTIVE To systematically review systematic reviews of school-based sexual-health and relationship Education (SHRE) programmes and, thereby, identify interventions and intervention components that promote reductions in risky sexual behaviour among young people. METHODS Electronic bibliographies were searched systematically to identify systematic reviews of school-based interventions targeting sexual-health. Results were summarised using a narrative synthesis. RESULTS Thirty-seven systematic reviews (summarising 224 primary randomised controlled trials) met our inclusion and quality assessment criteria. In general, these reviews analysed distinct sets of primary studies, and no comprehensive review of available primary studies was identified. Interventions were categorised into five types that segment this review literature. Unfortunately, many reviews reported weak and inconsistent evidence of behaviour change. Nonetheless, integration of review findings generated a list of 32 design, content and implementation characteristics that may enhance effectiveness of school-based, sexual-health interventions. Abstinence-only interventions were found to be ineffective in promoting positive changes in sexual behaviour. By contrast, comprehensive interventions, those specifically targeting HIV prevention, and school-based clinics were found to be effective in improving knowledge and changing attitudes, behaviours and health-relevant outcomes. CONCLUSIONS School-based interventions targeting risky sexual behaviour can be effective. Particular design, content and implementation characteristics appear to be associated with greater effectiveness. We recommend consideration of these characteristics by designers of school-based sexual-health interventions.

Abstract
Access to high-quality reproductive health care is important for adolescents and young adults with HIV infection to prevent unintended pregnancies, sexually transmitted infections, and secondary transmission of HIV to partners and children. As perinatally HIV-infected children mature into adolescence and adulthood and new HIV infections among adolescents and young adults continue to occur in the United States, medical providers taking care of such individuals often face issues related to sexual and reproductive health. Challenges including drug interactions between several hormonal methods and antiretroviral agents make decisions regarding contraceptive options more complex for these adolescents. Dual protection, defined as the use of an effective contraceptive along with condoms, should be central to ongoing discussions with HIV-infected young women and couples wishing to avoid pregnancy. Last, reproductive health discussions need to be integrated with discussions on HIV care, because a reduction in plasma HIV viral load below the level of detection (an "undetectable viral load") is essential for the individual's health as well as for a reduction in HIV transmission to partners and children.

Abstract
BACKGROUND Community interventions to promote condom use are considered to be a valuable tool to reduce the transmission of human immunodeficiency virus (HIV) and other sexually transmitted infections (STIs). In particular, special emphasis has been placed on implementing such interventions through structural changes, a concept that implies public health actions that aim to improve society's health through modifications in the context wherein health-related risk behavior takes place. This strategy attempts to increase condom use and in turn lower the transmission of HIV and other STIs. OBJECTIVES To assess the effects of structural and community-level interventions for increasing condom use in both general and high-risk populations to reduce the incidence of HIV and STI transmission by comparing alternative strategies, or by assessing the effects of a strategy compared with a control. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library, from 2007, Issue 1), as well as MEDLINE, EMBASE, AEGIS and ClinicalTrials.gov, from January 1980 to April 2014. We also handsearched proceedings of international acquired immunodeficiency syndrome (AIDS) conferences, as well as major behavioral studies conferences focusing on HIV/AIDS and STIs. SELECTION CRITERIA Randomized control trials (RCTs) featuring all of the following.1. Community interventions ('community' defined as a geographical entity, such as cities, counties, villages).2. One or more structural interventions whose objective was to promote condom use. These type of interventions can be defined as those actions improving accessibility, availability and acceptability of any given health program/technology.3. Trials that confirmed biological outcomes using laboratory testing. DATA COLLECTION AND ANALYSIS Two authors independently screened and selected relevant studies, and conducted further risk of bias assessment. We assessed the effect of treatment by pooling trials with comparable characteristics and quantified its effect size using risk ratio. The effect of clustering at the community level was addressed through intra-cluster correlation coefficients (ICCs), and sensitivity analysis was carried out with different design effect values. MAIN RESULTS We included nine trials (plus one study that was a subanalysis) for quantitative assessment. The studies were conducted in Tanzania, Zimbabwe, South Africa, Uganda, Kenya, Peru, China, India and Russia, comprising 75,891 participants, mostly including the general population (not the high-risk population). The main intervention was condom promotion, or distribution, or both. In general, control groups did not receive any active intervention. The main risk of bias was incomplete outcome data.In the meta-analysis, there was no clear evidence that the intervention had an effect on either HIV seroprevalence or HIV seroincidence when compared to controls: HIV incidence (risk ratio (RR) 0.90, 95% confidence interval (CI) 0.69 to 1.19) and HIV prevalence (RR 1.02, 95% CI 0.79 to 1.32). The estimated effect of the intervention on other outcomes was similarly uncertain: Herpes simplex virus 2 (HSV-2) incidence (RR 0.76, 95% CI 0.55 to 1.04); HSV-2 prevalence (RR 1.01, 95% CI 0.85 to 1.20); syphilis prevalence (RR 0.91, 95% CI 0.71 to 1.17); gonorrhoea prevalence (RR 1.16, 95% CI 0.67 to 2.02); chlamydia prevalence (RR 0.94, 95% CI 0.75 to 1.18); and trichomonas prevalence (RR 1.00, 95% CI 0.77 to 1.30). Reported condom use increased in the experimental arm (RR 1.20, 95% CI 1.03 to 1.40). In the intervention groups, the number of people reporting two or more sexual partners in the past year did not show a clear decrease when compared with control groups (RR 0.90, 95% CI 0.78 to 1.04), but knowledge about HIV and other STIs improved (RR 1.15, 95% CI 1.04 to 1.28, and RR 1.23, 95% CI 1.07 to 1.41, respectively). The quality of the evidence was deemed to be moderate for nearly all key outcomes. AUTHORS' CONCLUSIONS There is no clear evidence that structural interventions at the community level to increase condom use prevent the transmission of HIV and other STIs. However, this conclusion should be interpreted with caution since our results have wide confidence intervals and the results for prevalence may be affected by attrition bias. In addition, it was not possible to find RCTs in which extended changes to policies were conducted and the results only apply to general populations in developing nations, particularly to Sub-Saharan Africa, a region which in turn is widely diverse.

[PMID: 26052651 PMCID: PMC5861495 DOI: 10.1002/jrsm.1098] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2012] [Revised: 08/21/2013] [Accepted: 09/01/2013] [Indexed: 01/08/2023]
Abstract
Systematic reviews are an essential tool for researchers, prevention providers and policy makers who want to remain current with the evidence in the field. Systematic review must adhere to strict standards, as the results can provide a more objective appraisal of evidence for making scientific decisions than traditional narrative reviews. An integral component of a systematic review is the development and execution of a comprehensive systematic search to collect available and relevant information. A number of reporting guidelines have been developed to ensure quality publications of systematic reviews. These guidelines provide the essential elements to include in the review process and report in the final publication for complete transparency. We identified the common elements of reporting guidelines and examined the reporting quality of search methods in HIV behavioral intervention literature. Consistent with the findings from previous evaluations of reporting search methods of systematic reviews in other fields, our review shows a lack of full and transparent reporting within systematic reviews even though a plethora of guidelines exist. This review underscores the need for promoting the completeness of and adherence to transparent systematic search reporting within systematic reviews.

Abstract
Sexually transmitted infections (STIs) are common and costly, in part because they are asymptomatic and result in serious complications. Primary care clinicians can easily diagnose and effectively treat most STIs. Clinicians should screen patients for STIs based on high-risk behaviors, and consult with local public health officials to adapt national screening guidelines to local epidemiology. Clinical encounters involving STI screening are opportunities to counsel patients on risk behaviors, and vaccinate against human papillomavirus and hepatitis B. Electronic health records and mobile phone apps show promise for improving the clinical care of STIs.

Abstract
BACKGROUND The effectiveness of counseling messages to avoid unprotected sex during short-term treatment for curable sexually transmitted infections is unknown. METHODS We randomized 300 female STI clinic patients 18 years or older with cervicitis and/or vaginal discharge in Kingston, Jamaica, in 2010 to 2011, to 1 of 2 counseling messages for their course of syndromic treatment: abstinence only or abstinence backed up by condom use. At a follow-up visit 6 days afterward, we collected vaginal swabs to test for prostate-specific antigen (PSA), a biological marker of recent semen exposure, and administered a questionnaire assessing sexual behavior. RESULTS No differences were found in the proportions of women testing positive for PSA at follow-up in the abstinence-plus-condom group (11.9%) and abstinence-only group (8.4%) (risk difference, 3.5; 95% confidence interval, -3.5 to 10.5). There also was no significant difference in reporting of unprotected sex between groups. Reporting a history of condom use before enrollment significantly modified the effect of counseling arm on PSA positivity (P = 0.03). Among those reporting recent condom use, 10.3% in the abstinence-only arm and 4.8% in the abstinence-plus-condom arm tested positive for PSA. Conversely, among those not reporting recent condom use, 6.5% in the abstinence-only arm and 17.3% in the abstinence-plus-condom arm had PSA detected. CONCLUSIONS We found no evidence to support the superiority of either counseling message. Post hoc analyses suggest that women with recent condom experience may benefit significantly more from abstinence-plus-condom messages, whereas women without such experience may benefit significantly more from abstinence-only messages. Providers should weigh individual condom use history when determining the most appropriate counseling message.

Abstract
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.

Abstract
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.

Abstract
BACKGROUND Homeless youth are at high risk for HIV infection as a consequence of risky sexual behaviour. Interventions for homeless youth are challenging. Assessment of the effectiveness of interventions to modify sexual risk behaviours for preventing HIV in homeless youth is needed. OBJECTIVES To evaluate and summarize the effectiveness of interventions for modifying sexual risk behaviours and preventing transmission of HIV among homeless youth. SEARCH STRATEGY We searched electronic databases (CENTRAL, MEDLINE, EMBASE, AIDSearch, Gateway, PsycInfo, LILACS), reference lists of eligible articles, international health agency publication lists, and clinical trial registries. The search was updated January 2010. We contacted authors of published reports and other key role players. SELECTION CRITERIA Randomised studies of interventions to modify sexual risk behaviour (biological, self-reporting of sexual-risk behaviour or health-seeking behaviour) in homeless youth (12-24 years). DATA COLLECTION AND ANALYSIS Data from eligible studies were extracted by two reviewers. We assessed risk of bias per the Cochrane Collaborations tool. None of the eligible studies reported any primary biological outcomes for this review. Reports of self-reporting sexual risk behaviour outcomes varied across studies precluding calculation of summary measures of effect; we present the outcomes descriptively for each study. We contacted authors for missing or ambiguous data. MAIN RESULTS We identified three eligible studies after screening a total of 255 unique records. All three were performed in the United States of America and recruited substance-abusing male and female adolescents (total N=615) through homeless shelters into randomised controlled trials of independent and non-overlapping behavioural interventions. The three trials differed in theoretical background, delivery method, dosage (number of sessions,) content and outcome assessments. Overall, the variability in delivery and outcomes precluded estimation of summary of effect measures. We assessed the risk of bias to be high for each of the studies. Whilst some effect of the interventions on outcome measures were reported, heterogeneity and lack of robustness in these studies necessitate caution in interpreting the effectiveness of these interventions. AUTHORS' CONCLUSIONS The body of evidence does not permit conclusions on the impact of interventions to modify sexual risk behaviour in homeless youth; more research is required. While the psychosocial and contextual factors that fuel sexual risk behaviours among homeless youth challenge stringent methodologies of RCT's, novel ways for program delivery and trial retention are in need of development. Future trials should comply with rigorous methodology in design, delivery, outcome measurement and reporting.

Abstract
BACKGROUND Sexual health promotion is a major public health challenge; there is huge potential for health promotion via technology such as the Internet. OBJECTIVES To determine effects of interactive computer-based interventions (ICBI) for sexual health promotion, considering cognitive, behavioural, biological and economic outcomes. SEARCH STRATEGY We searched more than thirty databases for randomised controlled trials (RCTs) on ICBI and sexual health, including CENTRAL, DARE, MEDLINE, EMBASE, CINAHL, British Nursing Index, and PsycINFO. We also searched reference lists of published studies and contacted authors. All databases were searched from start date to November 2007, with no language restriction. SELECTION CRITERIA RCTs of interactive computer-based interventions for sexual health promotion, involving participants of any age, gender, sexual orientation, ethnicity or nationality. 'Interactive' was defined as packages that require contributions from users to produce tailored material and feedback that is personally relevant. DATA COLLECTION AND ANALYSIS Two review authors screened abstracts, applied eligibility and quality criteria and extracted data. Results of RCTs were pooled using a random-effects model with standardised mean differences (SMDs) for continuous outcomes and odds ratios (ORs) for binary outcomes. We assessed heterogeneity using the I(2) statistic. Separate meta-analyses were conducted by type of comparator: 1) minimal intervention such as usual practice or leaflet, 2) face-to-face intervention or 3) a different design of ICBI; and by type of outcome (cognitive, behavioural, biological outcomes). MAIN RESULTS We identified 15 RCTs of ICBI conducted in various settings and populations (3917 participants). Comparing ICBI to 'minimal interventions' such as usual practice, meta-analyses showed statistically significant effects as follows: moderate effect on sexual health knowledge (SMD 0.72, 95% CI 0.27 to 1.18); small effect on safer sex self-efficacy (SMD 0.17, 95% CI 0.05 to 0.29); small effect on safer-sex intentions (SMD 0.16, 95% CI 0.02 to 0.30); and also an effect on sexual behaviour (OR 1.75, 95% CI 1.18 to 2.59). Data were insufficient for meta-analysis of biological outcomes and analysis of cost-effectiveness.In comparison with face-to-face sexual health interventions, meta-analysis was only possible for sexual health knowledge, showing that ICBI were more effective (SMD 0.36, 95% CI 0.13 to 0.58). Two further trials reported no difference in knowledge between ICBI and face-to-face intervention, but data were not available for pooling. There were insufficient data to analyse other types of outcome.No studies measured potential harms (apart from reporting any deterioration in measured outcomes). AUTHORS' CONCLUSIONS ICBI are effective tools for learning about sexual health, and they also show positive effects on self-efficacy, intention and sexual behaviour. More research is needed to establish whether ICBI can impact on biological outcomes, to understand how interventions might work, and whether they are cost-effective.

Abstract
Background Following universal access to antiretroviral therapy in Thailand, evidence from National AIDS Spending Assessment indicates a decreasing proportion of expenditure on prevention interventions. To prompt policymakers to revitalize HIV prevention, this study identifies a comprehensive list of HIV/AIDs preventive interventions that are likely to be effective and cost-effective in Thailand. Methods A systematic review of the national and international literature on HIV prevention strategies from 1997 to 2008 was undertaken. The outcomes used to consider the effectiveness of HIV prevention interventions were changes in HIV risk behaviour and HIV incidence. Economic evaluations that presented their results in terms of cost per HIV infection averted or cost per quality-adjusted life year (QALY) gained were also included. All studies were assessed against quality criteria. Results The findings demonstrated that school based-sex education plus life-skill programs, voluntary and routine HIV counselling and testing, male condoms, street outreach programs, needle and syringe programs, programs for the prevention of mother-to-child HIV transmission, male circumcision, screening blood products and donated organs for HIV, and increased alcohol tax were all effective in reducing HIV infection among target populations in a cost-effective manner. Conclusion We found very limited local evidence regarding the effectiveness of HIV interventions amongst specific high risk populations. This underlines the urgent need to prioritise health research resources to assess the effectiveness and cost-effectiveness of HIV interventions aimed at reducing HIV infection among high risk groups in Thailand.

Abstract
AIM To examine the effectiveness of interventions seeking to prevent the spread of sexually transmitted infections (STIs), including HIV, among young people in the European Union. METHODS For this systematic review, we examined interventions that aimed at STI risk reduction and health promotion conducted in schools, clinics, and in the community for reported effectiveness (in changing sexual behavior and/or knowledge) between 1995 and 2005. We also reviewed study design and intervention methodology to discover how these factors affected the results, and we compiled a list of characteristics associated with successful and unsuccessful programs. Studies were eligible if they employed a randomized control design or intervention-only design that examined change over time and measured behavioral, biologic, or certain psychosocial outcomes. RESULTS Of the 19 studies that satisfied our review criteria, 11 reported improvements in the sexual health knowledge and/or attitudes of young people. Ten of the 19 studies aimed to change sexual risk behavior and 3 studies reported a significant reduction in a specific aspect of sexual risk behavior. Two of the interventions that led to behavioral change were peer-led and the other was teacher-led. Only 1 of the 8 randomized controlled trials reported any statistically significant change in sexual behavior, and then only for young females. CONCLUSION The young people studied were more accepting of peer-led than teacher-led interventions. Peer-led interventions were also more successful in improving sexual knowledge, though there was no clear difference in their effectiveness in changing behavior. The improvement in sexual health knowledge does not necessarily lead to behavioral change. While knowledge may help improve health-seeking behavior, additional interventions are needed to reduce STIs among young people.

Abstract
CONTEXT Abstinence-only education has had little demonstrable impact on teenagers' sexual behaviors, despite significant policy and funding efforts. Given the struggle over resources to improve teenagers' reproductive health outcomes, the views of clinicians serving teenagers at high risk for unintended pregnancy and STDs merit particular attention. METHODS In 2005, a qualitative study with 31 clinicians serving low-income, at-risk patients was conducted. A semistructured interview guide was used to ask clinicians about adolescent pregnancy, HIV and STD prevention counseling, and when they include abstinence. Thematic content analysis was used to examine the content of the counseling and the techniques used in different situations. RESULTS Providers reported offering comprehensive counseling, presenting abstinence as a choice for teenagers, along with information about contraceptives and condoms. Several providers mentioned that with young, sexually inexperienced teenagers, they discuss delaying sexual activity and suggest other ways to be affectionate, while giving information on condoms. Providers explained how they assess whether teenagers feel ready to be sexually active and try to impart skills for healthy relationships. Some described abstinence as giving teenagers a way to opt out of unwanted sexual activity. Many support abstinence if that is the patient's desire, but routinely dispense condoms and contraceptives. CONCLUSIONS Overall, providers did not give abstinence counseling as a rigid categorical concept in their preventive practices, but as a health tool to give agency to teenagers within a harm reduction framework. Their approach may be informative for adolescent policies and programs in the future.

Abstract
BACKGROUND Resource allocation models have not had a substantial impact on HIV/AIDS resource allocation decisions in spite of the important, additional insights they may provide. In this paper, we highlight six difficulties often encountered in attempts to implement such models in policy settings; these are: model complexity, data requirements, multiple stakeholders, funding issues, and political and ethical considerations. We then make recommendations as to how each of these difficulties may be overcome. RESULTS To ensure that models can inform the actual decision, modellers should understand the environment in which decision-makers operate, including full knowledge of the stakeholders' key issues and requirements. HIV/AIDS resource allocation model formulations should be contextualized and sensitive to societal concerns and decision-makers' realities. Modellers should provide the required education and training materials in order for decision-makers to be reasonably well versed in understanding the capabilities, power and limitations of the model. CONCLUSION This paper addresses the issue of knowledge translation from the established resource allocation modelling expertise in the academic realm to that of policymaking.

Abstract
PURPOSE Several randomized, controlled trials (RCTs) have tested strategies to prevent sexual acquisition of HIV infection, but their quality has been variable. We aimed to identify, describe, and evaluate the quality of RCTs studying biomedical interventions to prevent HIV acquisition by sexual transmission. METHOD We conducted a systematic review to identify all RCTs evaluating the efficacy of biomedical HIV prevention interventions. We assessed seven generic and content-specific quality components important in HIV prevention trials, factors influencing study power, co-interventions provided, and trial ethics. RESULTS We identified 26 eligible RCTs. The median number of quality components judged to be in adequate or unclear was 3 (range 1-4) in 1992-1998, 3 (range 1-4) in 1999-2003, and 0 (range0-2) in 2004-2008 (p < .001). Common problems that may have biased results included low retention (median 84%), poor adherence to interventions requiring on going use (median < or =78%), and lower HIV incidence than expected a priori (in 8 of 11 trials where evaluable). CONCLUSION Reporting of trials of biomedical HIV prevention interventions has improved over time. However, quality improvement is needed in several key areas that influence study power, including participant retention, adherence to interventions, and estimation of expected HIV incidence.

PURPOSE OF REVIEW We review the current state of evidence-based prevention strategies for reducing sexual transmission of HIV. The combined programmatic and scientific efforts through 2008 to reduce sexual transmission of HIV have failed to reduce substantially the global pandemic. RECENT FINDINGS Prevention interventions to reduce HIV infection target behavioral, biomedical, and structural risk factors. Some of these prevention strategies have been evaluated in randomized clinical trials (RCTs) with HIV seroincidence endpoints. When RCTs are not feasible, a variety of observational and quasiexperimental research approaches can provide insight as to program effectiveness of specific strategies. Only five RCTs have demonstrated a notable decrease in sexually acquired HIV incidence. These include the Mwanza study of syndromic management of sexually transmitted diseases and three male circumcision trials in East Africa; a microbicide trial reported in 2009 shows substantial promise for the efficacy of PRO 2000 (0.5% gel). SUMMARY The combined programmatic and scientific efforts to reduce sexual transmission of HIV have made incremental progress. New prevention tools are needed to stem the continued spread of HIV, though microbicides and vaccines will take many more years to develop, test, and deploy. Combination strategies of existing modalities should be tested to evaluate the potential for more proximate prevention benefits.
