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）： 这项拟议中的研究探讨了强化减肥计划对 未治疗的配偶和家庭环境。既往体重控制研究 他们的评估完全集中在个人身上， 参与者。这种评估策略可能低估了 体重控制治疗，并可能错过重要的环境预测因素， 减肥的结果。在拟议的研究中，480名Look AHEAD参与者和 他们的配偶将从3个临床地点招募（布朗大学， 亚拉巴马大学伯明翰分校、明尼苏达大学）。参与者和 将在基线和1年随访时对配偶进行评估。信息 参与者的体重、身高和人口统计数据将从 协调中心。此外，与会者将完成的措施， 饮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， 对饮食摄入量和体力活动进行全面评估。配偶也将 成为家庭环境的主要报告者，并将完成以下措施： 食物的可获得性、食物储存量和家中运动器材的数量。 我们的主要分析将检查是否未经治疗的配偶的干预 参与者比未接受标准护理的配偶减轻更多体重 参与者我们的二次分析将检查 从基线到1年，参与者的体重和体重相关行为是 与配偶在同一时间内相同测量的变化相关 期我们还将研究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， 这些变化是否预测参与者和配偶的体重减轻。最后我们 将探讨家庭环境的变化是否会调节这种关系 参与者和配偶之间的体重减轻。辅助系统中收集的数据 这项研究将为行为减肥的范围提供新的信息 治疗和关于家庭环境在减肥中的作用。
