Background: Maternal morbidity and neonatal mortality is increased in adolescents and pregnant women without prenatal care or poor adherence. Objective: To identify the influence of adolescence and its surroundings on adherence to prenatal care and its impact on prematurity and/or low birth weight and neonatal mortality. Methods: Case-control study, conducted with 570 pregnant adolescents and 2093 ≥20 years of age whose infants were hospitalized in a neonatal unit. Associations were determined by Odds Ratio with confidence interval of 95%, using the multivariate logistic regression analysis. To build the model with Classification and Regression Trees variables in the bivariate had had a p<0.05 was used. Results: Maternal age 13-19 was found associated with poor adherence to prenatal care, after adjusting for schooling <11 years, lack of spouse or life partner, lack of social security in health and pregnancy history of ≥2 pregnancies. This poor adherence to prenatal care was associated with increased risk of prematurity and/or low birth weight and increased neonatal mortality. Conclusions: The teen was found independently associated with poor adherence to prenatal care, but there are other important determinants of poor adherence, which in turn was found associated with prematurity and/or low birth weight, and neonatal mortality.
