Résumé : This study aims to estimate the prevalence of adolescent pregnancy (AP) in three Brazilian cities - Salvador, Rio de Janeiro, and Porto Alegre - and to examine the profiles of pregnant girls and their partners in relation to pregnancy outcomes. Data for a retrospective assessment of AP were collected using an interview-based household survey applied to a stratified sample of males and females aged 18-24. A total of 4,634 individuals were interviewed (85.2 % of the eligible individuals). 21.4% of males and 29.5% of females aged 20-24 reported AP, but few such pregnancies had taken place before age 15 (0.6% and 1.6%). Pregnancy between adolescent partners was reported by 55.1% of males and 27.9% of females. 79.8% of the latter became pregnant while involved in a stable relationship with an older partner. AP levels varied inversely to schooling and income levels. 72.2% of females and 34.5% of males carried their first AP to completion, and more cases of induced abortion were reported by male partners in pregnancies (41.3%) than by females (15.3%). With the birth of the first child, 25.0% of women interrupted their studies temporarily and 17.3% definitively. However, 42.1% of primiparous mothers were already outside school before pregnancy.
