This study aimed to assess factors associated with teen pregnancy among low-income Brazilian adolescents (N = 452) with pregnancy experience (n = 226) and without this experience (n = 226). The mean of age of the sample was 16.86 years old (SD = 1.35) and 64% were girls. A multivariate analysis demonstrated that teen pregnancy was associated with: living with the partner; use of oral contraception; lower age of the fi rst sexual intercourse; use of alcoholic drinks; and lesser division of home chores. Teen pregnancy tends to appear when a conjugation of developmental risk variables exists. This information can be important with a view to interventions focused on this population, as well as for teen pregnancy prevention campaigns.
