Repeated pregnancy among adolescents and negative outcomes of the newborn: study in the city of Rio de Janeiro. Rev. bras. epidemiol. [online]. 2012, vol.15, n.3, pp.443-454.

The aim of the study was to evaluate the prevalence of repeated pregnancy among adolescents and identify associated factors and perinatal outcomes. A sample of 1,986 post-partum adolescents was selected from public hospitals in the city of Rio de Janeiro, Brazil. To verify the hypothesis of homogeneity of proportions, chi-square tests (χ2) were used. Odds ratios and correspondent confidence intervals were estimated. Logistic regression procedures were used. A repeated pregnancy prevalence of 31.4% was identified and the principal associated factors were: maternal age 15-19 years; paternal age >19 years; early menarche; black or brown maternal skin color; schooling < 5 years; living with partner during pregnancy. Perinatal death was significantly higher in the adolescent mothers group with repeated pregnancy. The results showed that the most disadvantaged socioeconomic conditions were found among adolescent mothers with repeated pregnancy in comparison to mothers on their first pregnancy. The findings sustain the relevance of social policies for adolescent mothers with repeated pregnancy.
