The aim of this secondary analysis was to compare the effects of time-restricted eating (TRE) versus daily calorie restriction (CR) on sleep quality, duration, insomnia severity, and risk of obstructive sleep apnea in adults with obesity over one year. A total of 90 participants were randomized to one of three groups for 12 months: 8 h TRE (eating only between 12 p.m. and 8 p.m.); CR (25% daily calorie restriction) or a no-intervention control group. By the end of the study, weight loss was 4.61 kg (95% CI; 7.37 to 1.85 kg; ≤ 0.01) for the TRE group and 5.42 kg (CI; 9.13 to 1.71 kg; ≤ 0.01) for the CR group, with no statistically significant difference between TRE and CR (0.81 kg [CI; 3.07 to 4.69]; = 0.68]). Self-reported sleep quality, sleep duration, insomnia severity, and risk of obstructive sleep apnea did not change in the TRE or CR groups versus controls by month 12. These findings suggest that the weight loss produced by TRE and CR does not have any impact on various sleep parameters in adults with obesity over one year.
本二次分析旨在比较限时进食（TRE）与每日热量限制（CR）对肥胖成年人一年以上睡眠质量、时长、失眠严重程度和阻塞性睡眠呼吸暂停风险的影响。共有 90 名参与者随机分为三组，持续 12 个月：8 小时 TRE（仅在中午 12 点至晚上 8 点之间进食）；CR（每日热量限制 25%）或不干预对照组。研究结束时，TRE 组体重减轻 4.61 公斤（95%CI；7.37 至 1.85 公斤； ≤ 0.01），CR 组体重减轻 5.42 公斤（CI；9.13 至 1.71 公斤； ≤ 0.01），TRE 和 CR 之间无统计学差异（0.81 公斤 [CI；3.07 至 4.69]；= 0.68））。在 TRE 或 CR 组与对照组相比，12 个月时自我报告的睡眠质量、睡眠时长、失眠严重程度和阻塞性睡眠呼吸暂停风险均无变化。这些发现表明，TRE 和 CR 引起的体重减轻对肥胖成年人一年以上的各种睡眠参数没有影响。
