  1. School-based interventions for preventing HIV, sexually transmitted infections, and pregnancy in adolescents (Review)

    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.

  2. Effective approaches for programming to reduce adolescent vulnerability to HIV infection, HIV risk, and HIV-related morbidity and mortality: A systematic review of systematic reviews

    Background: In 2012, an estimated 2.1 million adolescents were living with HIV. Though there are effective interventions to prevent and treat HIV infection, adolescents face specific barriers in accessing them. As a result, new infections and poor outcomes among HIV-infected adolescents are common. HIV programming for adolescents should focus on interventions of proven effectiveness and address underlying factors driving incidence and lack of effective treatment and care in this age group. …

  3. Nothing as practical as good theory? The theoretical basis of HIV prevention interventions for young people in sub-Saharan Africa: A systematic review

    This paper assesses the extent to which HIV prevention interventions for young people in sub-Saharan Africa are grounded in theory and if theory-based interventions are more effective. Three databases were searched for evaluation studies of HIV prevention interventions for youth. Additional articles were identified on websites of international organisations and through searching references. 34 interventions were included; 25 mentioned the use of theory. …

  4. A tale of two countries: rethinking sexual risk for HIV among young people in South Africa and the United States

    This paper compares the sexual behaviors of young people in South Africa (SA) and the United States (US) with the aim of better understanding the potential role of sexual behavior in HIV transmission in these two countries that have strikingly different HIV epidemics. Nationally representative, population-based surveys of young people ages 18-24 years from SA (n = 7,548) and the US (n = 13,451) were used. The prevalence of HIV was 10.2% in SA and 1% in the US. …
