Factors associated with first sexual intercourse among mothers with 14-16 years of age from Porto Alegre/RS, Brazil.

Abstract：

:This study analyzed the factors associated with first sexual intercourse among 427 mothers with 14-16 years of age from Porto Alegre (RS), Brazil. Data on adolescent socio-demographic status (skin color, religion and schooling gap) and reproductive aspects (age at menarche, age at first sexual intercourse, partnership in first sexual intercourse and partner's age) were collected through household survey. Data analysis was performed using bivariate and multivariate analysis through Poisson regression with robust variance. Among adolescents with early first sexual intercourse (up to 14 years), 77.4% had menarche at up to 12 years of age and 16.4% had casual partners in the first sexual intercourse. These variables were associated with the outcome and showed that early menarche (OR=1.26; CI 95%:1.04-1.52) and casual partner at first sexual intercourse (OR=1.28; CI 95%:1.09-1.49) increase by respectively 26% and 28% the prevalence of early first sexual intercourse. This study highlights the need to strengthen health programs and policies already implemented, such as the School Health Program, as well as reinforces that parents and teachers need to be oriented in an integrated manner in order to facilitate dialogue with adolescents and provide adequate counseling. :O presente estudo analisou os fatores associados à iniciação sexual em 427 mães de 14 a 16 anos de Porto Alegre/RS/Brasil. Foram coletados dados referentes à condição sociodemográfica das adolescentes (cor da pele, religião e defasagem escolar) e dimensão reprodutiva (idade na menarca, idade na iniciação sexual, tipo de parceria na iniciação sexual e idade do parceiro) através de inquérito domiciliar. A avaliação dos dados foi realizada com o uso de análise bivariada e multivariada através de regressão de Poisson com variância robusta. Entre as adolescentes com iniciação sexual precoce (até os 14 anos), 77,4% tiveram menarca até os 12 anos e o parceiro na iniciação sexual foi casual em 16,4% dos casos. Essas variáveis foram associadas ao desfecho e mostram que menarca precoce (RP=1,26; IC95%:1,04-1,52) e parceiro casual na iniciação sexual (RP=1,28; IC95%:1,09-1,49) aumentam em, respectivamente, 26% e 28% a prevalência da iniciação sexual precoce. Este estudo evidencia a necessidade de fortalecer os programas e políticas de saúde já implantados, como o Programa Saúde do Escolar, e reforça que pais e professores precisam ser orientados de maneira integrada com o fim de facilitar o diálogo com as adolescentes e promover um aconselhamento adequado.
