Abstract Objectives: to evaluate coverage and identify factors associated with adequate prenatal care for adolescent mothers in Rio Grande, Southern Brazil, in a period of 13 years. Methods: over the years 2007, 2010, 2013, 2016 and 2019, a single standardized questionnaire was applied to all mothers at hospital level in this municipality. The outcome consisted of the proportion of puerperae women who started prenatal care in the first trimester and performed 6+ medical visits, completed 2+ HIV, syphilis, and urine tests. Chi-square test was used for proportions, Poisson regression in the multivariate analysis and the prevalence ratio (PR) as measure of effect. Results: among the 12,645 identified mothers, 2,184 (17.3%) were adolescents. Of this total, 35.2% (CI95%= 33.2%-37.2%) had received adequate prenatal care, ranging from 13.8% (10.8%-16.7%) in 2007 to 52,5% (46.8%-58.1%) in 2019. The adjusted analysis showed a higher PR for adequate prenatal care among those of older age and better schooling level, white/brown skin color, with a partner, never had an abortion, were primiparous and non-smokers. Conclusion: there was substantial improvement in coverage of adequate prenatal care over the period studied, but there is still a long way to go. The increase in this coverage depends on reaching adolescents who are younger, less educated, black skin color, living without a partner, multiparous and smokers. |
