ABSTRACT Yoga has been proposed as a strategy for improving risk and protective factors for eating disorders, but few prevention trials have been conducted. The purpose of this pilot study was to assess the feasibility and acceptability of a yoga series in female college students (n = 52). Participants were randomized to a yoga intervention (three 50-minute yoga classes/week for 10 weeks conducted by certified yoga teachers who received a 3-day intensive training) or a control group. Risk and protective factors, assessed at baseline, 5 and 10 weeks, included body dissatisfaction, negative affect, loneliness, self-compassion, positive affect, and mindfulness. Mixed models controlling for baseline levels of outcome variables were run. On average, participants attended 20 out of 30 yoga classes, and the majority of participants reported high levels of satisfaction with the yoga series. Appearance orientation decreased and positive affect increased in the yoga group relative to the control group. After controlling for baseline levels, the yoga group had a significantly higher positive affect than the control group. Changes in other outcomes were not statistically significant, as compared to the control condition. Future yoga research directions are discussed including education about body image, measure and sample selection, and use of an implementation science framework.

瑜伽对饮食失调的风险和保护因素的影响：一项预防性试验

摘要 瑜伽已被提议作为改善饮食失调的风险和保护因素的策略，但很少进行预防试验。这项试点研究的目的是评估女大学生（n = 52）瑜伽系列的可行性和可接受性。参与者被随机分配到瑜伽干预组（由接受 3 天强化训练的认证瑜伽老师进行为期 10 周的每周 3 次 50 分钟的瑜伽课程）或对照组。在基线、第 5 周和第 10 周评估的风险和保护因素包​​括对身体的不满、负面影响、孤独、自我同情、积极影响和正念。运行控制结果变量基线水平的混合模型。平均而言，参与者参加了 30 个瑜伽课程中的 20 个，大多数参与者对瑜伽系列表示高度满意。与对照组相比，瑜伽组的外貌倾向降低，正面影响增加。在控制基线水平后，瑜伽组的积极影响明显高于对照组。与对照条件相比，其他结果的变化没有统计学意义。讨论了未来的瑜伽研究方向，包括关于身体形象的教育、测量和样本选择，以及实施科学框架的使用。与对照条件相比，其他结果的变化没有统计学意义。讨论了未来的瑜伽研究方向，包括关于身体形象的教育、测量和样本选择，以及实施科学框架的使用。与对照条件相比，其他结果的变化没有统计学意义。讨论了未来的瑜伽研究方向，包括关于身体形象的教育、测量和样本选择，以及实施科学框架的使用。
