RESUMO
Repeated pregnancy (RP) among adolescents is seldom researched in Brazil, even tough the debate on the reproductive rights is important for this extract of population. A transversal study was developed with data from the Declaration of Live Births of adolescent mothers, living in Rio de Janeiro (RJ, Brazil), in 2005. The aim was to estimate the magnitude and features associated with RP. Prevalence ratios (PR) of RP, with 95% confidence interval (CI) for selected variables, were estimated through log-binomial multivariate regression. Among 12,168 adolescents, a RP prevalence of 29.1% was identified and the principal factors associated were: age 15-19 anos (PR=5.42; RI 95% 3.72-7.81); not doing prenatal consultation (RP=2.36; CI 95% 2.16-2.58); educational status<4 anos (PR=1.48; CI 95% 1.25-1.76); housewife job (PR=1.8; CI 95% 1.57-2.15) or other (PR=1.9; CI 95%; 1.73-2.10). Giving birth by cesarean section and low birth weight were negatively associated to repeated pregnancy with RP equal to 0,94 (CI 95%; 0,86-0,99) and 0.69 (CI 95%; 0.62-0.77). The adolescents with RP had worst socioeconomic and assistance indicators than those on their first pregnancy. Specific social policies for adolescent mothers, in vulnerable situation, will enable them to have better conditions to exercise their reproductive rights.

A recorrência da gravidez na adolescência é tema pouco estudado no Brasil, sendo necessário o debate dos direitos reprodutivos dessa parcela da população. Realizou-se estudo transversal com dados das Declarações de Nascidos Vivos de mães adolescentes residentes na cidade do Rio de Janeiro (RJ) do ano de 2005, com o objetivo de conhecer a magnitude e as características associadas à gravidez recorrente (GR). Foram estimadas razões de prevalência de GR com intervalos de confiança (IC) de 95 por cento para variáveis selecionadas através de regressão multivariada log-binomial. Entre 12.168 adolescentes, identificou-se prevalência de GR de 29,1 por cento. Os principais fatores associados à GR foram: idade 15-19 anos (RP=5,42 IC95 por cento 3,72-7,81); não realizar pré-natal (RP=2,36 IC95 por cento 2,16-2,58); escolaridade<4anos (RP=1,48 IC95 por cento 1,25-1,76); ocupação dona de casa (RP=1,8 IC 95 por cento 1,57-2,15) ou outra (RP=1,9 IC95 por cento 1,73-2,10). Parto cesáreo e baixo peso foram associados negativamente a GR com RP iguais a 0,94 (IC95 por cento 0,86-0,99) e 0,69 (IC95 por cento 0,62-0,77). As adolescentes com gravidez recorrente tiveram indicadores socioeconômicos e assistenciais piores do que aquelas na primeira gravidez. Políticas sociais específicas para adolescentes mães em situação de vulnerabilidade possibilitariam melhores condições para o exercício de seus direitos reprodutivos.
