Gender, peer and partner influences on adolescent HIV risk in rural South Africa

Abstract

In preparation for a school-based intervention in KwaZulu-Natal, South Africa, a cross-sectional survey of potential HIV risk factors in youth aged 14-17 (n=983) was conducted. Boys were significantly more likely than girls to report lifetime sexual activity (37.7% v. 13.8%, P<0.01). Among boys and girls, 46.1% reported condom use at last sex. Discussion of condom use with a partner was the strongest predictor of condom use (boys, odds ratio (OR)=7.39; girls, OR=5.58, P<0.0001). Age was independently associated with sexual activity for boys (OR=1.49, P<0.0001) and girls (OR=1.74, P=0.02). For boys, perceptions of male peer behaviour were associated with both ever having participated in sexual activity (OR=1.48, P<0.01) and condom use at last sex (OR=1.79, P<0.01). Girls who equated condom use with having numerous partners were more likely to use them. Among boys, results challenged some expected gender beliefs: support for girls' initiative in relationship formation and refusal of sex were significant predictors of sexual activity. Among girls, higher pregnancy risk perception (OR=1.32, P=0.02) and knowledge (OR=4.85, P=0.055) were associated with sexual activity. Creating more gender equitable norms can reduce HIV risk behaviours. HIV prevention interventions should build on existing gender equitable beliefs, and work to promote others, including sexual communication and negotiation skills, and modelling of positive peer norms.
