Role of home environment in weight loss maintenance

描述(由申请人提供)： 这项拟议的研究考察了密集减肥计划对 未经治疗的配偶和家庭环境。体重控制的先期研究 治疗将他们的评估完全集中在个人身上 参与者。这一评估策略可能低估了 体重控制治疗，可能会错过重要的环境预测指标 减肥的结果。在拟议的研究中，480名前瞻参与者和 他们的配偶将从3个临床站点招募(布朗大学， 阿拉巴马大学伯明翰分校、明尼苏达大学)。参与者和 配偶将在基线和一年的随访中进行评估。有关的信息 参赛者的体重、身高和人口统计数据将从 协调中心。此外，参与者还将完成以下措施 膳食摄入量和体力活动(如果不包括在核心评估中) 和社会支持。配偶的体重和身高将被测量，他们将 完成对饮食摄入量和体力活动的评估。配偶们也会 作为家居环境的主要记者，将完成措施 食物的可获得性，食物的储存，以及家里运动器材的数量。 我们的初步分析将检查未接受治疗的配偶是否接受干预 参与者比接受标准护理的未经治疗的配偶减掉更多体重 参与者。我们的二次分析将检查是否有变化 参与者从基线到1年的体重和与体重相关的行为是 与配偶在相同时间内相同指标的变化相关 句号。我们还将检查是否在家庭中观察到更多的变化 干预参与者的环境比标准护理参与者和 这些变化是否会预测参与者和配偶的体重下降。最后，我们 将探讨家庭环境的变化是否会调解这种关系 参与者和配偶之间的减肥。在附件中收集的数据 研究将提供有关行为减肥范围的新信息 治疗和关于家庭环境在减肥中的作用。

DESCRIPTION (provided by applicant): The proposed study examines the impact of an intensive weight loss program on untreated spouses and the home environment. Prior studies of weight control treatment have focused their assessments exclusively on the individual participant. This assessment strategy may underestimate the positive effects of weight control treatment and may miss important environmental predictors of weight loss outcomes. In the proposed study, 480 Look AHEAD participants and their spouses will be recruited from 3 clinical sites (Brown University, University of Alabama at Birmingham, University of Minnesota). Participants and spouses will be assessed at baseline and 1-year follow-up. Information on participants' weight, height, and demographics will be obtained from the Coordinating Center. In addition, participants will complete measures of dietary intake and physical activity (if not included in the core assessments) and social support. Spouses' weight and height will be measured and they will complete assessments of dietary intake and physical activity. Spouses will also be the primary reporter of the home environment and will complete measures of food availability, food storage, and amount of exercise equipment in the home. Our primary analysis will examine whether untreated spouses of intervention participants lose more weight than untreated spouses of standard care participants. Our secondary analyses will examine whether changes in participants' weight and weight-related behaviors from baseline to 1-year are correlated with changes on the same measures in spouses over the same time period. We will also examine whether more change is observed in the home environments of intervention participants than standard care participants and whether these changes predict participant and spouse weight loss. Finally, we will explore whether changes in the home environment mediate the relationship between participant and spouse weight loss. The data collected in the ancillary study will provide new information about the reach of behavioral weight loss treatment and about the role of the home environment in weight loss.
