Preprints with The Lancet is part of SSRN´s First Look, a place where journals identify content of interest prior to publication. Authors have opted in at submission to The Lancet family of journals to post their preprints on Preprints with The Lancet. The usual SSRN checks and a Lancet-specific check for appropriateness and transparency have been applied. Preprints available here are not Lancet publications or necessarily under review with a Lancet journal. These preprints are early stage research papers that have not been peer-reviewed. The findings should not be used for clinical or public health decision making and should not be presented to a lay audience without highlighting that they are preliminary and have not been peer-reviewed.

Background: Comprehensive sexuality education (CSE) seeks to reduce risky sexual behaviour and subsequent incidence of unintended pregnancy and HIV among school going adolescents. This study evaluates differences between in and out of school adolescent girls and the effect of exposure to CSE on key biomedical and behavioural indicators in South Africa.
Methods: Data were collected from a household-based representative sample of adolescent girls (between the ages 12–18 years) in four high HIV prevalence DREAMS implementation districts in South Africa. Independent variables included school attendance and exposure to CSE, with outcome variables measuring prevalence of HIV, pregnancy and sexual behaviour, including condom use, incidence of age disparate relationships and transactional sex.
Findings Attending school is associated with reduced adjusted odds of having engaged in sexual activity (AOR: 0·58, 95% CI: 0·48-0·70, p < 0·001); using condoms inconsistently in the previous 12 months (AOR: 0·48, 95% CI: 0·34-0·65, p <0·001); having 2 or more sex partners in the previous 12 months (AOR: 0·72, 95% CI: 0·57-0·92, p < 0·05); and having ever been pregnant (AOR: 0·41, 95% CI: 0·32-0·52, p <0·001). Adolescent girls in school and who had attended CSE in the previous 12 months were associated with reduced adjusted odds of being HIV positive (Full sample: AOR: 0·76, 95% CI: 0·61-0·95, p < 0·05; sexually active sample: AOR: 0·62, 95% CI: 0·40-0·96, p < 0·05).
Interpretation This study shows that schooling reduces risky sexual behaviours, whilst additional exposure CSE has a protective effect against HIV acquisition. Exposure to CSE has also resulted in increased access to HIV testing for adolescent girls both in and out of school. Keeping adolescent girls in school produces the greatest positive sexual behavioural effect, this coupled with the delivery of quality CSE, is a key strategy for reducing HIV risk.
