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）计划可导致临床上显着的体重减轻；然而长期利率 WL维护很差。先前的研究表明，长期的 WL 成功可能需要增强克服生理和享乐冲动的能力以及处理生活的能力得到提高压力源、负面情绪状态和对食物的渴望。因此，针对减轻压力和减少使用食物作为应对厌恶经历的策略的倾向可能会产生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方法减轻压力，改善整体身心健康，并为加强长期维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种潜在的心理过程（例如，正念、抗压能力），可以减少情绪化饮食，改善饮食选择，并增强一个人忍受食物渴望或享乐冲动的能力。虽然瑜伽是一种有效的治疗方法其他慢性健康状况，尚未被视为改善长期健康状况的潜在干预措施 WL 结果。在肥胖领域的背景下，瑜伽被视为一种锻炼方式，而不是必然作为一种身心干预方法（就像其他领域的情况一样）。因此，考虑到较低的热量与许多形式的有氧运动相比，瑜伽的支出，瑜伽对重要体重的影响相关过程和行为尚未经过检查。本研究旨在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），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接受为期 12 周的标准行为测试 WL 计划，然后是 12 周的团体瑜伽或 12 周的烹饪/饮食信息类。两组将被指导进行自我监控并实现饮食和有氧运动目标整个24周的计划。评估将在基线以及第 12 周和第 24 周进行。将评估瑜伽干预计划的满意度。 YOGA和CON将在总体上进行比较（感知压力、正念、痛苦耐受力）和饮食特定变量（享乐、情绪和饮食）正念饮食）通过问卷调查和生态瞬时评估（EMA）进行评估。 EMA 将用于捕捉通过智能手机实时发生的饮食诱惑、渴望和饮食失误；客观的身体活动监测器将检查瑜伽和瑜伽之间的有氧运动水平是否存在差异 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为未来有关瑜伽功效的研究工作提供信息，这是 WL 身心干预的一个例子维护，以及瑜伽影响体重的心理机制。
