Abstract
The objective of this study was to evaluate the determinants of weight gain during pregnancy. The study adopted a prospective cohort design with four follow-up waves and included a sample of 255 pregnant women that received prenatal care at a public health care facility in Rio de Janeiro, Brazil. A mixed-effects linear longitudinal regression model was used, having as the dependent variable the weight assessed in four follow-up waves, and as independent variables: demographic, socioeconomic, reproductive, behavioral, and nutritional data. Mean weight gain was 0.413kg per gestational week, consistent with recommendations by the Institute of Medicine. Per capita family income and smoking were associated with total weight gain during gestation. According to the longitudinal multiple linear regression model, age (² = 0.6315), menarche (² = -2.3861), triglycerides (² = 0.0437), blood glucose (² = 0.1544), and adequacy of energy consumption (² = -0.0642) were associated with gestational weight gain. Special attention should be given to these sub-groups, due to increased risk of excessive weight gain.
O objetivo do estudo foi avaliar os fatores determinantes da evolução ponderal durante a gestação. Trata-se de uma investigação com desenho do tipo coorte prospectiva com quatro ondas de seguimento, composta por 255 gestantes atendidas em pré-natal público da cidade do Rio de Janeiro, Brasil. Utilizou-se o procedimento de regressão linear longitudinal com efeitos mistos, tendo como variável dependente o peso aferido em quatro ondas de seguimento, e como independentes variáveis demográficas e sócio-econômicas, reprodutivas, comportamentais e nutricionais. A velocidade média de ganho de peso ponderal foi de 0,413kg por semana de gestação, compatível com o recomendado pelo Institute of Medicine (Estados Unidos). A renda familiar per capita e o hábito de fumar estiveram associados ao ganho de peso total na gestação. O modelo múltiplo de regressão linear longitudinal revelou que a idade (² = 0,6315), menarca (² = -2,3861), triglicérides (² = 0,0437), glicose (² = 0,1544) e adequação do consumo energético (² = -0,0642) estiveram associados ao ganho de peso gestacional. Sugere-se atenção especial para esses subgrupos, em decorrência do maior risco de ganho excessivo.
