本研究的目的是评估怀孕期间体重增加的决定因素。该研究采用前瞻性队列设计，有四个随访波，包括在巴西里约热内卢的公共卫生保健机构接受产前护理的255名孕妇的样本。采用混合效应线性纵向回归模型，以四个随访波中评估的体重为因变量，以人口统计学、社会经济学、生殖、行为和营养数据为自变量。平均体重增加0.413公斤每妊娠周，符合医学研究所的建议。人均家庭收入和吸烟与妊娠期总体重增加有关。根据纵向多元线性回归模型，年龄（β = 0.6315），月经初潮（β = -2.3861），甘油三酯（β = 0.0437），血糖（β = 0.1544）和能量消耗充足（β = -0.0642）与妊娠期体重增加相关。由于体重过度增加的风险增加，应特别注意这些亚组。
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 (beta = 0.6315), menarche (beta = -2.3861), triglycerides (beta = 0.0437), blood glucose (beta = 0.1544), and adequacy of energy consumption (beta = -0.0642) were associated with gestational weight gain. Special attention should be given to these subgroups, due to increased risk of excessive weight gain.
