项目摘要

Project summary/abstract Behavioral weight loss (WL) programs result in clinically significant weight losses; however rates of long-term WL maintenance are poor. Previous studies suggest that long-term WL success may require an enhanced ability to overcome physiological and hedonic urges to eat and an improved capacity for dealing with life stressors, negative mood states, and food cravings. Thus interventions which target stress reduction and reduce the tendency to use food as a coping strategy for aversive experiences may offer a protective effect against dietary lapses; thereby improving long-term WL outcomes. Yoga is a mind-body intervention which reduces stress and improves overall physical and psychological well-being and offers promise for strengthening the psychological skill set needed for maintaining important weight-related behaviors long-term. The physical and cognitive skills practiced within yoga target multiple underlying psychological processes (e.g., mindfulness, distress tolerance) which could reduce emotional eating, improve dietary choices, and enhance one's ability to tolerate food cravings or hedonic urges to eat. While yoga is an effective treatment approach for other chronic health conditions, it has not been examined as a potential intervention for improving long-term WL outcomes. Within the context of the obesity field, yoga has been viewed as a mode of exercise and not necessarily as a mind-body intervention approach (as is the case in other fields). Thus, given the lower caloric expenditure of yoga in comparison to many forms of aerobic exercise, the effect of yoga on important weight- related processes and behaviors has not been examined. This study aims to examine the feasibility and acceptability of implementing yoga within a weight management program and to examine the impact of yoga, relative to a contact-control condition (CON), on important psychological constructs and weight-related behaviors. Sixty women with a BMI of 25-40 kg/m2 will be randomly assigned to a 12-week standard behavioral WL program, followed by either 12 weeks of group-based yoga or 12 weeks of cooking/dietary information classes. Both groups will be instructed to self-monitor and achieve the dietary and aerobic exercise goals throughout the 24-week program. Assessments will occur at baseline and weeks 12 and 24. Attendance and program satisfaction with the yoga intervention will be assessed. YOGA and CON will be compared on general (perceived stress, mindfulness, distress tolerance), and eating-specific variables (hedonic, emotional, and mindful eating) assessed via questionnaire, and by ecological momentary assessment (EMA). EMA will be used to capture dietary temptations, cravings, and dietary lapses, as they occur in real-time via smartphones; objective physical activity monitors will examine whether levels of aerobic exercise differ between YOGA and CON. Treatment groups will be compared on 12-24 week changes in weight. These preliminary findings can be used to inform future research efforts on the efficacy of yoga, an example of a mind-body intervention for WL maintenance, and the psychological mechanisms through which yoga may influence body weight.

项目概要/摘要行为减肥（WL）计划导致临床上显着的体重减轻;然而， WL维护很差。以前的研究表明，长期WL的成功可能需要加强克服生理和享乐欲望的能力，以及改善处理生活的能力压力源、负面情绪状态和食物渴望。因此，针对减轻压力和减少使用食物作为应对厌恶体验的策略的倾向可能会提供保护作用防止饮食失误;从而改善长期WL结果。瑜伽是一种身心干预，减轻压力，改善整体身心健康，并为加强长期保持重要的体重相关行为所需的心理技能。瑜伽中练习的身体和认知技能针对多个潜在的心理过程（例如，正念，痛苦容忍度），这可以减少情绪化饮食，改善饮食选择，并提高一个人对食物的渴望或享乐欲望的忍受能力。虽然瑜伽是一种有效的治疗方法，其他慢性健康状况，它还没有被检查作为一个潜在的干预措施，以改善长期 WL结果。在肥胖领域的背景下，瑜伽一直被视为一种锻炼方式，而不是作为一种身心干预方法（在其他领域也是如此）。因此，考虑到低热量瑜伽的消耗相比，许多形式的有氧运动，瑜伽对重要的体重的影响- 相关的过程和行为没有被检查。本研究的目的是探讨可行性和在体重管理计划中实施瑜伽的可接受性，并检查瑜伽的影响，相对于接触控制条件（CON），对重要的心理结构和体重相关行为。60名BMI为25-40 kg/m2的女性将被随机分配到一个为期12周的标准行为检查组， WL计划，然后是12周的小组瑜伽或12周的烹饪/饮食信息班两组都将被指导自我监测和实现饮食和有氧运动的目标在24周的计划中。将在基线和第12周和第24周进行评估。出勤和将评估对瑜伽干预的方案满意度。瑜伽和CON将在一般情况下进行比较（感知压力，正念，痛苦容忍度）和饮食特定变量（享乐，情绪，注意饮食）通过问卷调查和生态瞬时评估（EMA）进行评估。EMA将用于通过智能手机实时捕捉饮食诱惑、渴望和饮食失误; 客观的身体活动监测器将检查有氧运动水平是否在瑜伽和 CON.将比较治疗组12-24周的体重变化。这些初步发现可以用于通知未来的研究工作，瑜伽的功效，一个例子，身心干预WL 维持，以及瑜伽可能影响体重的心理机制。
