Inadequate weight gain during pregnancy is an important predictor of complications for the mother and infant. This cross-sectional study assessed factors associated with inadequate weight gain among women in the third trimester of pregnancy who received prenatal care under the Brazilian Unified National Health System (SUS) in the city of Rio de Janeiro, Brazil, from November 2007 to July 2008. A total of 1,079 pregnant women were interviewed, and adequacy of weight gain was obtained by calculating weight gain as recommended by the U.S. Institute of Medicine. Social, demographic, and obstetric factors were analyzed as independent variables. A multinomial logistic regression model was used, and pregnant women with weight gain below or above the recommended levels were compared to those with adequate weight gain. Low schooling was associated with insufficient weight gain, while excessive gain was observed in women with hypertension and pre-gestational underweight, overweight, and obesity. Nutritional assessment during prenatal care is essential, and interventions should target cases of inadequate weight gain in order to prevent complications for the mother and infant.
孕期体重增加不足是母亲和婴儿并发症的一个重要预测因素。本横断面研究评估了 2007 年 11 月至 2008 年 7 月在巴西里约热内卢市接受巴西统一国家卫生系统（SUS）产前保健的孕妇中与孕期第三个三月体重增加不足相关的因素。共对 1079 名孕妇进行了访谈，并通过计算美国医学研究所推荐的体重增加来获得体重增加的充足性。将社会、人口统计学和产科因素作为自变量进行分析。采用多项逻辑回归模型，将体重增加低于或高于推荐水平的孕妇与体重增加充足的孕妇进行比较。低教育程度与体重增加不足有关，而高血压和孕前体重不足、超重和肥胖的孕妇体重增加过多。产前保健期间的营养评估至关重要，干预措施应针对体重增加不足的情况，以预防母婴并发症。
