Dating violence among school students in Tanzania and South Africa: prevalence and socio-demographic variations.

AIMS: Widespread adolescent dating violence (DV) in Sub-Saharan Africa calls for immediate action, particularly since it is linked to the spread of HIV/AIDS. This article presents prevalence and demographic correlates of DV among school students in Cape Town and Mankweng (South Africa) and Dar es Salaam (Tanzania). METHODS: Data were derived from the baseline data collection of a multi-site randomized controlled trial of an HIV prevention intervention among young adolescents. The results were confined to students who reported previously or currently being in a relationship (n = 6,979). Multiple logistic regression analysis with demographic predictors was employed, controlled for cluster effect. RESULTS: Within our sample 10.2%-37.8% had been victims, 3.1%-21.8% had been perpetrators, and 8.6%-42.8% had been both (percentages dependent on site and gender). Before controlling for other factors, religion was a protective factor against violence in Cape Town. After controlling for other factors, a higher age and lower socioeconomic status were associated with belonging to any of the three groups of violence. Being male in all sites was associated with perpetration; being female with victimization (except in Cape Town where the converse finding was obtained). Higher parental education in Cape Town was protective against all types of violence. Ethnicity and living with biological parents were not associated with violence. CONCLUSIONS: DV is prevalent and widespread in the study sites. Violence control policies and interventions should target young adolescents. Since there was not one clearly defined subgroup identified as being at high risk, such programmes should not be limited to high risk groups only.

Predictors of early first sexual intercourse among adolescents in Cape Town, South Africa.

Early coital debut is a risk factor for HIV. In this paper we investigate the predictors of young adolescents' transition to first intercourse using a social cognition theoretical framework. The analyses reported here were based on a longitudinal study of 2,360 students in the schools allocated to the control arm of a cluster-randomized controlled trial to investigate the effect of a school-based HIV prevention programme among Grade 8 students in Cape Town. Structural equation modelling was performed with Mplus version 3.11. Of the 1440 students who were virgins at baseline, 1,144 remained virgins 15 months later and 296 (20.6%) reported having had their first sexual intercourse. Transition to first sexual intercourse was more likely among males than females, among older students and among students with a lower socio-economic status. Transition to first sexual intercourse was significantly associated with intentions to have sexual intercourse, poor self-efficacy to negotiate delayed sex and intimate partner violence. The model predicted 35% of the variance in intentions and 16% of the variance in transition. These findings indicate some of the factors that influence young adolescent's transition to first intercourse and that need to be addressed when designing effective interventions.
