Sleep disturbance is a common problem among adults with obesity. Mindfulness interventions have been shown to improve sleep quality in various populations but have not been investigated in adults with obesity. The aim of this study was to compare the effects of a mindfulness-based weight-loss intervention with an active control on self-reported sleep quality among adults with obesity.
This study was a secondary analysis of a randomized controlled trial and included 194 adults with a body mass index in the range 30-45 kg/m. The treatment intervention included mindfulness-based eating and stress-management practices, and the active control intervention included training in progressive muscle relaxation (PMR). Both groups received identical diet and exercise guidelines in 17 group sessions conducted over 5.5 months that were matched for time, attention, and social support. The primary outcome of this analysis was between-group change in self-reported sleep quality, which was assessed using the Pittsburgh Sleep Quality Index (PSQI) global score at baseline and at 6, 12, and 18 months.
Between-group differences in mean PSQI change scores in the mindfulness group (n = 100) compared to the control group (n = 94) were -0.27 (-0.68, 1.22; p = 0.58) at 6 months, -0.57 (-0.35, 1.50; p = 0.22) at 12 months, and -0.50 (-0.53, 1.53; p = 0.34) at 18 months, all in the direction of more sleep improvement in the mindfulness group but none reaching statistical significance. In the mindfulness group, average weekly minutes of meditation practice time was associated with improved sleep quality from baseline to 6 months.
No statistically significant evidence was found that a weight-loss program that incorporates mindfulness improves self-reported sleep quality compared to a control diet/exercise intervention that included PMR. Within the mindfulness group, average weekly minutes of mindfulness practice was associated with improved sleep quality.
睡眠障碍是肥胖成年人中的常见问题。正念干预已被证明能改善不同人群的睡眠质量，但尚未在肥胖成年人中进行研究。本研究的目的是比较基于正念的减肥干预与积极对照对肥胖成年人自我报告的睡眠质量的影响。
本研究是一项随机对照试验的二次分析，纳入了194名体重指数在30至45kg/m范围内的成年人。治疗干预包括基于正念的饮食和压力管理实践，积极对照干预包括渐进性肌肉松弛（PMR）训练。两组在为期5.5个月的17次小组会议中接受相同的饮食和运动指导，这些会议在时间、关注度和社会支持方面相匹配。该分析的主要结果是自我报告的睡眠质量的组间变化，使用匹兹堡睡眠质量指数（PSQI）全球评分在基线以及6、12和18个月时进行评估。
与对照组（n = 94）相比，正念组（n = 100）在6个月时的平均PSQI变化得分的组间差异为-0.27（-0.68，1.22；p = 0.58），12个月时为-0.57（-0.35，1.50；p = 0.22），18个月时为-0.50（-0.53，1.53；p = 0.34），所有这些差异均表明正念组的睡眠改善更多，但均未达到统计学显著性。在正念组中，从基线到6个月，平均每周的冥想练习时间与睡眠质量改善相关。
没有发现统计学上显著的证据表明，与包含PMR的对照饮食/运动干预相比，纳入正念的减肥计划能改善自我报告的睡眠质量。在正念组中，平均每周的正念练习时间与睡眠质量改善相关。
