This paper compares the sexual and reproductive experiences and intentions of those adolescents aged 15-19 years in Uganda who are perinatally infected with HIV and know their sero-status with those of adolescents who do not know their sero-status. The analysis comprises a simple comparison of means and proportions, together with the relevant tests of significance, as well as estimation of Cox proportional hazards and random-effects logit models. The findings show that the two groups of adolescents do not differ significantly in terms of timing of sexual debut and whether they intend to have children in the future. However, adolescents who are HIV-positive and know their status are significantly more likely to use a modern method of contraception, including condoms. Nonetheless, the level of condom use among these adolescents is still limited (less than half of those sexually active) and inconsistent (less than half of those in relationships reported always using a condom).
