目的：为了确定是否有孕前节食和限制饮食的历史是与较高的体重增加pregnancy.Design饮食的做法进行了评估之间的一个前瞻性队列的孕妇使用修订的限制规模。妇女被分为三个独立的分量表，限制饮食者，节食者，体重循环者。受试者包括1,223名妇女在怀孕，感染，主要结果测量妊娠期总体重增加和体重增加的充分性（基于医学研究所推荐的观察到的/预期的体重增加的比率）进行统计分析。增加的结果，同时控制潜在的混杂因素，包括体力活动和体重增加的attitudes.Results有每个分量表和总体重增加之间的正相关，以及足够的体重增加。被归类为骑自行车的妇女比不骑自行车的妇女平均增加2公斤，观察/预期比值高出0.2个单位。在限制饮食者和节食者中，体重指数的影响不同。除体重不足的妇女外，所有其他有节食或限制饮食史的体重状况妇女在怀孕期间体重增加更多，体重增加比率更高。相比之下，体重不足的妇女与历史上的限制饮食行为增加体重较轻的体重不足的妇女没有这些behaviors.Conclusions限制饮食行为与体重增加以上的医学研究所的建议，正常，超重和肥胖的妇女，体重增加低于建议体重不足的妇女。妊娠期体重过度增加是值得关注的，因为它与产后体重保持有关。饮食限制工具是有用的，以确定妇女谁将受益于营养咨询之前或怀孕期间就实现有针对性的体重增加的建议。美国饮食协会杂志2008;108：1646-1653。
Objective To determine whether a history of preconceptional dieting and restrained eating was related to higher weight gains in pregnancy.Design Dieting practices were assessed among a prospective cohort of pregnant women using the Revised Restraint Scale. Women were classified on three separate subscales as restrained eaters, dieters, and weight cyclers.Subjects Participants included 1,223 women in the Pregnancy, Infection, and Nutrition Study.Main outcome measures Total gestational weight gain and adequacy of weight gain (ratio of observed/expected weight gain based on Institute of Medicine recommendations).Statistical analyses performed Multiple linear regression was used to model the two weight-gain outcomes, while controlling for potential confounders including physical activity and weight-gain attitudes.Results There was a positive association between each subscale and total weight gain, as well as adequacy of weight gain. Women classified as cyclers gained an average of 2 kg more than noncyclers and showed higher observed/expected ratios by 0.2 units. Among restrained eaters and dieters, there was a differential effect by body mass index. With the exception of underweight women, all other weight status women with a history of dieting or restrained eating gained more weight during pregnancy and had higher adequacy of weight gain ratios. In contrast, under-weight women with a history of restrained eating behaviors gained less weight compared to underweight women without those behaviors.Conclusions Restrained eating behaviors were associated with weight gains above the Institute of Medicine's recommendations for normal, overweight, and obese women, and weight gains below the recommendations for underweight women. Excessive gestational weight gain is of concern because of its association with postpartum weight retention. The dietary restraint tool is useful for identifying women who would benefit from nutritional counseling prior to or during pregnancy with regard to achieving targeted weight-gain recommendations.
