项目摘要

DESCRIPTION (provided by applicant): High postpartum weight retention occurs in approximately 25 percent of young adult women and is an independent predictor of long-term weight gain, obesity, and obesity-related comorbidities. Preliminary efforts to reduce postpartum weight retention have met with some success but been limited by high attrition (30-40 percent) and failing to reach the populations at greatest risk (i.e., multiethnic, low income women). Innovative methods are needed to leverage women's naturally occurring motivation for weight control during the postpartum time period while captivating a greater proportion of the at risk population. Over the past decade, Internet use has increased exponentially in the US and most rapidly among young adult, low income, and minority sub-groups. Internet-based weight control interventions have been effective in promoting significant weight loss in obese populations. However, to date, no study has evaluated the effects an Internet-based program to prevent high postpartum weight retention in low-income women. We propose to develop and test the long-term efficacy of an Internet-based weight control program tailored for low-income postpartum mothers. We will be collaborating with the Women, Infants, and Children (WIC) program, which is a federally- funded community-based program providing nutritional support for low income multi-ethnic women. In this clustered randomized trial, 408 postpartum women with high postpartum weight retention will be randomized by clinic (N = 12) to either 12-month standard WIC or to a 12-month WIC Enhanced plus Internet-based postpartum weight loss program. Participants will be assessed at baseline, 6, and 12 months. The primary hypothesis is that the WIC Enhanced plus Internet program will produce significantly greater weight losses than the WIC Standard Care at 6 and 12 months; the intervention is also expected to increase the proportion of women who return to pre-pregnancy weight after 6 and 12 months. The project will provide a much-needed service to an underserved poplation and produce an empirically-based treatment package designed to be disseminated through WIC in the state of California and beyond.

描述（由申请人提供）：大约25％的年轻妇女出现了产后较高的体重，并且是长期体重增加，肥胖和与肥胖相关的合并症的独立预测指标。减少产后体重的初步努力已经取得了成功，但受到大量损耗（30-40％）的限制，未能以最大的风险达到人口（即多种族，低收入妇女）。需要创新的方法来利用妇女在产后期间自然发生的体重控制动机，同时吸引了更大比例的AT风险人群。在过去的十年中，在美国，低收入和少数族裔子群体中，互联网的使用呈指数增长。基于互联网的体重控制干预措施可有效促进肥胖人群的重大体重减轻。但是，迄今为止，尚无研究评估基于互联网的计划，以防止低收入女性的产后体重较高。我们建议开发和测试针对低收入产后母亲量身定制的基于互联网的体重控制计划的长期疗效。我们将与妇女，婴儿和儿童（WIC）计划合作，该计划是一项以联邦资助的社区计划，为低收入多种族妇女提供营养支持。在这项聚集的随机试验中，诊所（n = 12）将408个具有高产后体重的产后妇女与12个月的标准WIC或12个月的WIC增强型加上Internet的基于Internet的基于Internet的后体重减轻计划。参与者将在基线，6和12个月的时间进行评估。主要假设是WIC增强加上互联网计划将比6个月和12个月的WIC标准护理产生的体重减轻要大得多。预计该干预措施还会增加6个月和12个月后恢复孕前体重的妇女比例。该项目将为服务欠佳的poplation提供急需的服务，并生产基于经验的治疗套件，旨在通过加利福尼亚州及以后的WIC传播。
