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.

描述（由申请人提供）： 拟议的研究检查了强化减肥计划对 未经处理的配偶和家庭环境。先前的体重控制研究 治疗专门针对个人的评估 参与者。这种评估策略可能会低估 体重控制处理，可能会错过重要的环境预测指标 减肥结果。在拟议的研究中，有480位参与者和 他们的配偶将从3个临床场所招募（布朗大学， 阿拉巴马大学明尼苏达大学伯明翰）。参与者和 配偶将在基线和1年随访中进行评估。信息 参与者的体重，身高和人口统计将从 协调中心。此外，参与者将完成 饮食摄入和体育锻炼（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衡量，他们将 饮食摄入和体育锻炼的完整评估。配偶也会 成为家庭环境的主要记者，并将完成 食品可用性，食物储存和家庭中的运动设备数量。 我们的主要分析将检查未经处理的干预配偶 参与者的体重比未经治疗的标准护理配偶更大 参与者。我们的次要分析将检查是否改变 参与者的体重和体重相关的行为从基线到1年 与同一时间相同措施的变化相关 时期。我们还将检查房屋中是否观察到更多变化 干预参与者的环境比标准护理参与者和 这些变化是否预测参与者和配偶减肥。最后，我们 将探索家庭环境中的变化是否调解关系 在参与者和配偶减肥之间。辅助收集的数据 研究将提供有关行为减肥范围的新信息 治疗以及家庭环境在减肥中的作用。
