Prevalence and associated factors on overweight/obesity in pregnant women assisted by the Family Health Strategy

Abstract

Abstract Objectives: to estimate the prevalence of overweight/obesity and analyze the associated factors in pregnant women assisted by family health teams. Methods: epidemiological observational study of populational, cross-sectional, and analytical base carried out with pregnant women at the Estratégia de Saúde da Família (Family Health Strategy) in the city of Montes Claros, Minas Gerais State, Brazil, between October 2018 and November 2019. Socioeconomic and demographic, obstetric characteristics, social and family support, emotional aspects and comorbidities. The presence of overweight/obesity was estimated by the initial Body Mass Index (up to the 13th gestational week) acquired from the pregnant woman’s health booklet. Hierarchized Poisson regression with robust variance was carried out. Results: a total of 1,279 pregnant women participated in this study. The prevalence of overweight/ obesity was 45.3% and was associated with the following factors: having a partner (PR=1.52; CI95% =1.24-1.86), higher family income (PR=1.23; CI95% =1.04-1.46), presence of previous pregnancies (PR=1.65; CI95% =1.39-1.95%), higher age group (PR=2.26; CI95% =1.70-3.01), gestational diabetes mellitus (PR=1.43; CI95% =1.21-1.69) and systemic arterial hypertension (PR=1.29; CI95% =1.04-1.61). Conclusion: there was a high prevalence of overweight/obesity in the evaluated pregnant women and its association with sociodemographic and obstetric factors and chronic comorbidities. There is a necessity for monitoring and carrying out nutritional education in prenatal care provided by family health teams, with emphasis on strengthening multidisciplinary care.
