[Subsequent pregnancy among adolescents]. / Reincidência de gravidez em adolescentes.

PURPOSE: To evaluate epidemiological aspects in recurrent adolescence pregnancy. METHODS: Cohort study including 187 pregnant adolescents attended and followed-up for five years after delivery in an adolescent's attendance service in Ceará state. Age group, being or not at school, living with parents, schooling, marital status and the present partner's condition were analyzed. Data were processed by the EPI-INFO program. Statistical analysis of the independent variables (age, schooling, being at school, having a job, living with parents, marital status and switching partners) was done and compared to the dependent variable (being or not pregnant after five years). The Fisher's exact test was used to evaluate the association among factors which could influence the pregnancy recurrence, the association being present when p<0.05. Risks related to schooling, marital status and multiple partners have been calculated, since these were significant factors for pregnancy recurrence. RESULTS: 61% of the adolescents got pregnant in the five years after the first delivery. Factors such as age, school, work or living with parents were not protective. Nevertheless, when the adolescents had eight or less years of schooling, the risk of getting pregnant has almost duplicated (relative risk (RR)=1.8 (CI 95%=1.3-2.6)). New pregnancies were more frequent among the single adolescents without a stable partner (RR=1.3 (CI 95%=1.1-1.6) and among the ones who had multiple partners (RR=1.4 (CI 95%=1.1-1.7)). CONCLUSIONS: Low schooling, multiple partners and non-stable bonds were risk factors for pregnancy recurrence.

Reincidência de gravidez em adolescentes / Subsequent pregnancy among adolescents

OBJETIVO: avaliar os aspectos epidemiológicos na reincidência de gravidez na adolescência. MÉTODOS: estudo de coorte que incluiu 187 adolescentes grávidas, atendidas e acompanhadas durante cinco anos após o parto em um serviço de atendimento de adolescentes do Estado do Ceará. Foram analisados: faixa etária, estar ou não estudando, morar com os pais, escolaridade, condição marital e condição do companheiro atual. Os dados foram digitados e analisados no programa EPI-INFO. Foram feitas análises estatísticas das variáveis independentes (idade, escolaridade, estudar, trabalhar, morar com os pais, estado civil e mudança de parceiro) e comparadas quanto à variável dependente (ter ou não uma nova gravidez cinco anos depois). O teste exato de Fisher foi utilizado para avaliar associação entre os fatores que poderiam influenciar a repetição da gravidez, considerado como tendo associação quando o p<0,05. Foram calculados os riscos relativos para a escolaridade, condição marital e mudança de parceiro por serem fatores que se mostraram significativos para a reincidência de gravidez. RESULTADOS: foi verificado que 61 por cento das adolescentes engravidaram nos cinco anos seguintes ao primeiro parto. Não foram fatores protetores: idade, estudar, trabalhar ou morar com os pais. Entretanto, quando as adolescentes tinham oito anos ou menos de escolaridade, o risco de engravidar quase duplicou (risco relativo (RR)=1,8 (IC95 por cento=1,3-2,6)). Novas gestações foram mais frequentes entre as solteiras sem companheiro estável (RR=1,3 (IC95 por cento=1,1-1,6)) e aquelas que mudaram de parceiro (RR=1,4 (IC95 por cento=1,1-1,7)). CONCLUSÕES: a baixa escolaridade, a mudança de parceiros e uniões não estáveis foram fatores de risco para reincidência de gravidez.
