DESCRIPTION (provided by applicant): In the recently completed NIDDK-funded project (DK 57439) "Weight Gain in Pregnancy: Staying in the Range," the combined clinical and patient education intervention was more successful in preventing excessive weight gain during pregnancy and postpartum weight retention in low income women than it was in higher income women. Dietary factors appeared to be a mechanism through which the intervention led to the positive outcomes. Little information exists concerning diet and excessive gestational weight gain and postpartum weight retention. Thus, the goal of this proposed project is to elucidate dietary factors that are associated with excessive gestational weight gain and postpartum weight retention using the data collected in two recently completed observational (HD29549) and intervention (DK 57439) studies. More specifically, this project aims primarily to: 1) Identify dietary constituents that are associated with excessive gestational weight gain and postpartum weight retention among women in the observational study (BMHP I), and 2) Identify food patterns that are associated with excessive gestational weight gain and weight retention at one year postpartum in BMHPI. The dietary components of primary interest are fat (% of calories from fat), carbohydrate (glycemic index and glycemic load), and calcium (dairy and non-dairy). The measurements of the dietary components come from a Willett food frequency questionnaire completed during pregnancy, at 6 months and one year postpartum. Data from this source will also be used to create the food intake patterns using factor analysis. Statistical analyses will be conducted to address the research objective. Beyond adding to the understanding of diet and gestational weight gain and postpartum weight retention, the findings of this research will be helpful in increasing the proportion of women who gain an appropriate amount of weight during pregnancy and promoting healthy body weights in women through the childbearing period of their lives.

描述（由申请人提供）：在最近完成的 NIDDK 资助项目（DK 57439）“妊娠期体重增加：保持在范围内”中，临床和患者教育相结合的干预措施在预防妊娠期和产后体重过度增加方面更为成功低收入女性的体重保持率高于高收入女性。饮食因素似乎是干预产生积极结果的一种机制。关于饮食和妊娠期体重过度增加以及产后体重保持的信息很少。因此，该项目的目标是利用最近完成的两项观察性 (HD29549) 和干预性 (DK 57439) 研究中收集的数据来阐明与妊娠期体重过度增加和产后体重保留相关的饮食因素。更具体地说，该项目的主要目标是：1) 确定观察性研究 (BMHP I) 中与女性妊娠期体重过度增加和产后体重保持相关的饮食成分，以及 2) 确定与妊娠期体重过度相关的食物模式BMHPI 产后一年的增重和体重保持情况。主要关注的膳食成分是脂肪（脂肪卡路里的百分比）、碳水化合物（血糖指数和血糖负荷）和钙（乳制品和非乳制品）。膳食成分的测量结果来自威利特在怀孕期间、产后 6 个月和一年时完成的食物频率调查问卷。该来源的数据还将用于通过因子分析创建食物摄入模式。将进行统计分析以实现研究目标。除了增加对饮食和妊娠期体重增加以及产后体重保持的了解之外，这项研究的结果还将有助于增加怀孕期间体重适当增加的女性比例，并促进女性在整个育龄期保持健康的体重他们的生活。
