DESCRIPTION (provided by applicant): Weight loss interventions can produce clinically meaningful weight reductions, although most individuals experience significant weight regain following treatment. While the biological, behavioral, and environmental factors influencing long-term weight loss maintenance (WLM) are complex, it is clear that behaviors and reinforcers facilitating WLM differ greatly from those required for initial weight loss. However, we currently lack a well-specified conceptual framework that integrates and organizes behavioral, environmental, social, and cultural factors related to WLM. Additionally, weight loss treatment outcomes differ for African Americans and Whites, with African Americans losing less weight initially and Whites experiencing greater long-term weight regain. However, the reasons for these racial/ethnic differences in treatment response are unclear. Therefore, the goal of this project is to improve our understanding of factors associated with WLM and weight regain for African Americans and Whites who previously achieved clinically meaningful weight loss (i.e., >5% weight reduction). By utilizing validated methods novel to the investigation of WLM, including the nominal group technique (NGT), card-sorting tasks, and cognitive mapping, we will examine factors associated with successful WLM as well as weight regain among African Americans and Whites. By recruiting from several ongoing weight loss studies, including the PI's current K23 randomized controlled trial of a WLM program, we will have access to sufficient numbers of individuals who previously achieved weight loss. In particular, we will target four groups of participants: 1) African American weight loss maintainers, 2) African American weight regainers, 3) White weight loss maintainers, and 4) White weight regainers. Through the NGT, African American and White weight loss maintainers and regainers will generate comprehensive and potentially culturally-specific lists of facilitators and barriers to WLM (Aim #1). These facilitators and barriers will then be prioritized and organized into meaningful categories by participants through card-sorting tasks, which will be included in cluster analytic methods and cognitive mapping to develop conceptual frameworks of WLM for African Americans and Whites (Aim #2). Findings from this study will help us understand differences in response to weight loss and WLM treatments and guide the future development of culturally-tailored WLM interventions.

描述（由申请人提供）：减肥干预措施可能会导致临床上有意义的体重减轻，尽管大多数人在治疗后会重新获得重量。尽管影响长期减肥维持（WLM）的生物学，行为和环境因素很复杂，但很明显，行为和增强剂促进WLM的行为与初始体重减轻所需的行为差异很大。但是，我们目前缺乏一个明确指定的概念框架，该框架整合并组织了与WLM相关的行为，环境，社会和文化因素。此外，非洲裔美国人和白人的体重减轻治疗结果有所不同，非裔美国人最初减轻体重，而白人的长期体重更大。但是，这些种族/种族差异在治疗反应中的原因尚不清楚。因此，该项目的目的是提高我们对与WLM相关的因素的理解，并重新获得了以前实现临床有意义的体重减轻（即减轻> 5％）的非洲裔美国人和白人的体重。通过利用验证的方法来研究WLM的研究，包括名义组技术（NGT），卡片分类任务和认知映射，我们将研究与成功的WLM相关的因素，以及在非裔美国人和白人中恢复体重。通过从几项正在进行的减肥研究中招募，包括PI当前的WLM计划的K23随机对照试验，我们将可以访问足够数量的以前实现体重减轻的个人。特别是，我们将针对四组参与者：1）非裔美国人减肥者，2）非洲裔美国体重恢复，3）维持白色体重减轻的人，以及4）白色体重恢复。通过NGT，非洲裔美国人和白人减肥者和恢复者将产生全面且潜在的文化特定促进者和WLM障碍清单（AIM＃1）。然后，这些促进者和障碍将通过参与者通过卡片分级任务将优先级和组织为有意义的类别，这些任务将包括在集群分析方法和认知映射中，以开发WLM为非裔美国人和白人的概念框架（AIM＃2）。这项研究的结果将有助于我们了解减肥和WLM治疗的差异，并指导文化范围的WLM干预措施的未来发展。
