CAPUTO, Valéria Garcia and BORDIN, Isabel Altenfelder. Teenage pregnancy and frequent use of alcohol and drugs in the home environment. Rev. Saúde Pública [online]. 2008, vol.42, n.3, pp. 402-410. ISSN 0034-8910. http://dx.doi.org/10.1590/S0034-89102008000300003.
OBJECTIVE: To assess individual and family factors associated to teenage pregnancy, including frequent use of alcohol and illicit drugs by family members. METHODS: Case-control study conducted with a sample of 408 sexually active female adolescents (aged 13-17 years) in school from the city of Marília (Southeastern Brazil) in 2003-2004. Cases consisted of 100 primigravid teenagers assisted in prenatal care programs in health units. Controls were 308 nulligravid students from state public schools. Standardized instruments identified demographic and educational factors, contraceptive behavior, mental health problems, and family characteristics. Statistical analysis included chi-square tests and logistic regression models. RESULTS: Low paternal education (p=0.01), lack of information on sexuality and fertilization (p=0.001) and the use of illicit drugs by a resident family member (p=0.006) were independent risk factors. Family income per capita and asking the partner to use a condom were confounders. CONCLUSIONS: The frequent use of illicit drugs by a resident family member is a factor strongly associated to teenage pregnancy, regardless of other risk factors. The expectation of going to college constitutes a protective factor, mainly in the presence of low maternal education.
