Self-reported risky sexual practices among adolescents and young adults in Botswana

Adolescents and young adults account for more than one-third of incident Human Immunodeficiency Virus (HIV) infections globally. Understanding sexual practices of this high-risk group is critical in designing HIV targeted prevention programming.

To describe self-reported risky sexual practices of adolescents and young adults aged 16-24 years from 30 Botswana communities.

Cross-sectional, self-reported age at sexual debut; number of sexual partners; condom and alcohol use during sex; intergenerational sex; and transactional sex data were collected. Modified Poisson estimating equations were used to obtain univariate and multivariate-adjusted prevalence ratios (PR) and 95% confidence intervals (CI) comparing engagement in different sexual practices according to gender, accounting for the clustered design of the study.

Among the 3380 participants, 2311 reported being sexually active with more females reporting being sexually active compared to males (65% vs. 35%, respectively; p < 0.0001). In univariate analyses, female participants were more likely to report inconsistent condom use (PR 1.61; 95% CI 1.44-1.80), intergenerational sex (PR 9.00; 95% CI 5.84-13.88) and transactional sex (PR 3.46; 95% CI 2.07-5.77) than males, yet less likely to report engaging in sex before age 15 years (PR 0.59; 95% CI: 0.41-0.85), using alcohol around the time of intercourse (PR: 0.59; 95% CI 0.45-0.76) or having ≥ two partners in the last 12 months (PR 0.65; 95% CI 0.57-0.74).

Self-reported risky sexual practices of adolescents and young adults in Botswana differed significantly between males and females. Gender-specific risky sexual practices highlight the importance of developing tailored HIV prevention programming.
