The objective of this study is to contextualize adolescent pregnancy from milestones associated with the process of transition from youth to adulthood.


This is a cross-sectional study conducted with 200 adolescents, users of the Brazilian Unified Health System. The sample size for the estimation of proportions has been calculated assuming a population ratio of 0.50 and 95% confidence level. The dependent variables – planned pregnancy, living with a partner, and having left the parents’ house – have been considered as markers of transition from dependence to independence, from youth to adulthood. In the analysis of the associated factors, we have used the Poisson model with robust variance.


Average age was 17.3 years, and most adolescents lived with a partner; approximately half of the adolescents got pregnant from their first partner and the average age of first sexual intercourse was 14.6 years. Only 19% of the adolescents were studying and most dropped out of school before the beginning of the pregnancy. In the bivariate and multiple analysis, we could see that the relationship with a partner for more than two years was associated with the three dependent variables.


The path of transition to adulthood has been the establishment of a link with a partner and consequent pregnancy, suggesting a clear pattern of male guardianship. The changing role of women in society observed in recent decades, which means choosing a professional career, defining the number of children, and choosing their partner(s), has not reached these young persons.
