DESCRIPTION (provided by applicant): Obesity has reached epidemic proportions and represents a serious public health problem in the United States. Efforts to treat obesity have been only moderately successful, and attention has shifted toward prevention of weight gain, rather than treatment of obesity. Although average weight gain from pre- pregnancy to one-year postpartum is 2 kg, approximately 25 percent of women gain 5 kg or more during this period. Moreover, a recent study found that nearly 44 percent of normal weight women who had retained significant amounts of weight (M= 4.8 kg) at 12 months postpartum became overweight later in life. Thus, the period surrounding pregnancy appears to be an important time for prevention efforts. The single strongest predictor of weight gain from pre-to post-pregnancy is the magnitude of weight gained during pregnancy. The Institute of Medicine (IOM) has formulated specific recommendations for healthy weight gain during pregnancy. However, more than one-third of normal weight women and two thirds of overweight women exceed recommended levels of weight gain during pregnancy. Thus, helping women gain the recommended amount during pregnancy through healthy eating and physical activity would make a major contribution to preventing excessive weight retention. The principal aim of this study is to determine whether behavioral lifestyle intervention during pregnancy can reduce the number of normal weight and overweight women who exceed the IOM recommendations for weight gain during pregnancy. We propose to recruit 400 primiparous women and randomly assign these women to receive usual care or Intervention to Promote Healthy Weight Gain During Pregnancy. The Intervention group will receive weekly educational materials, weight monitoring with feedback, and supportive phone calls. All women will be followed from early pregnancy to 1-year postpartum. We believe this project is significant because it deals with the prevention of weight gain, which is a major health problem. The study is also innovative; there have been no adequately powered randomized controlled trials evaluating the effects of a behavioral lifestyle intervention delivered during pregnancy to promote healthy weight gain and prevent sustained postpartum weight retention.

描述（由申请人提供）：肥胖已经达到了流行病，代表了美国的严重公共卫生问题。治疗肥胖症的努力只是中等成功，并且注意力已转向预防体重增加，而不是治疗肥胖症。尽管从怀孕前到产后一年的平均体重增加为2公斤，但在此期间，约有25％的女性获得5公斤或更多。此外，最近的一项研究发现，在产后12个月时，近44％的正常体重妇女保留了大量体重（M = 4.8 kg）。因此，围绕怀孕的时期似乎是预防努力的重要时期。怀孕前到怀孕后体重增加的最强预测指标是怀孕期间增加的体重。医学研究所（IOM）提出了特定的建议，以便在怀孕期间健康体重增加。但是，超过三分之一的正常体重女性和三分之二的超重女性超过了怀孕期间建议体重增加的水平。因此，通过健康的饮食和体育锻炼帮助妇女在怀孕期间获得建议的数量将为防止过度保留量做出重大贡献。这项研究的主要目的是确定怀孕期间的行为生活方式干预是否可以减少超过IOM建议在怀孕期间体重增加的正常体重和超重女性的数量。我们建议招募400名初次妇女，并随机分配这些妇女接受通常的护理或干预措施，以促进怀孕期间健康的体重增加。干预小组将获得每周的教育材料，通过反馈和支持电话进行体重监控。从怀孕初期到产后1年，所有妇女将受到遵循。我们认为该项目很重要，因为它涉及预防体重增加，这是一个主要的健康问题。这项研究也是创新的。没有足够动力的随机对照试验来评估怀孕期间提供的行为生活方式干预措施的影响，以促进健康的体重增加并防止持续的产后体重减轻。
