背景：孕产妇肥胖和妊娠期体重过度增加（GWG）是孕产妇和胎儿并发症的主要短期和长期危险因素。目的：目的是研究基于手册或积极教育的生活方式干预是否可以改善肥胖孕妇的饮食习惯，增加体力活动（PA）并减少妊娠体重增加。设计：在这项随机对照试验中，195 名白人肥胖孕妇[年龄：29 +/- 4 岁；体重指数（单位：kg/m(2)）； 33.6 +/- 4.2]被随机分为3组：一组接受宣传册的营养建议，一组接受营养师的宣传册和生活方式教育，以及对照组。每三个月通过 7 天的食物记录评估营养习惯。 PA 采用 Baecke 问卷进行评估。结果：怀孕期间能量摄入没有变化，并且各组之间具有可比性。脂肪摄入量，特别是饱和脂肪摄入量。从妊娠早期到晚期，被动组和主动组的蛋白质摄入量减少，蛋白质摄入量增加，而对照组则相反。所有组在怀孕期间的钙摄入量和蔬菜消耗量均有所增加。所有组的 PA 均有所下降，尤其是在妊娠晚期。各组之间的 GWG 以及产科或新生儿结局没有显着差异。结论：两种生活方式干预措施均改善了肥胖女性怀孕期间的营养习惯。 PA 和 GWG 均未受到影响。蚂蚁临床营养杂志 2010；91：373-80。
Background: Maternal obesity and excessive gestational weight gain (GWG) are major short- and long-term risk factors for maternal and fetal complications.Objective: The objective was to study whether a lifestyle intervention based on a brochure or on active education can improve dietary habits, increase physical activity (PA), and reduce GWG in obese pregnant women.Design: In this randomized controlled trial, 195 white, obese pregnant women [age: 29 +/- 4 y; body mass index (in kg/m(2)); 33.6 +/- 4.2] were randomly assigned into 3 groups: a group that received nutritional advice from a brochure, a group that received the brochure and lifestyle education by a nutritionist, and a control group. Nutritional habits were evaluated every trimester through 7-d food records. PA was evaluated with the Baecke questionnaire.Results: Energy intake did not change during pregnancy and was comparable in all groups. Fat intake, specifically saturated fat intake. decreased and protein intake increased from the first to the third trimester in the passive and active groups compared with an opposite change in the control group. Calcium intake and vegetable consumption increased during pregnancy in all groups. PA decreased in all groups, especially in the third trimester. No significant differences in GWG and obstetrical or neonatal outcome could be observed between the groups.Conclusions: Both lifestyle interventions improved the nutritional habits of obese women during pregnancy. Neither PA nor GWG was affected. Ant J Clin Nutr 2010;91:373-80.
