Adolescents are at increased risk of HIV infection compared to other age groups. There is an urgent need for strategic information that will inform programmes to reduce risk and vulnerability to HIV and reverse the pattern of increasing HIV infection as they transition to adulthood. This paper analysed trends and factors associated with HIV prevalence among adolescents in South Africa using the national HIV population-based household surveys conducted in 2008, 2012 and 2017. All three surveys used a multistage cross-sectional design. A trend analysis was conducted to assess the differences in HIV prevalence and covariates overtime using P-trend Chi-squared statistic. Univariate and multivariate logistic regression models were used to determine factors associated with HIV prevalence. : Overall there was a significant increase in HIV prevalence among adolescents aged 12-19 years from 3.0% (n=2892) in 2008 to 3.2% (n=4829) in 2012 and 4.1% (n=3937) in 2017 (p=0.031). The odds of being HIV positive among adolescents aged 12-19 years was significantly higher among females [AOR=2.24; 95% CI (1.73-2.91); p p=0.001] population groups than Black Africans. The observed increasing trend and gender disparities in HIV prevalence suggests an urgent need for age appropriate and gender specific HIV interventions tailored and targeted at identified drivers of HIV infection among adolescents.
