Healthy sleep is associated with lower body weight and could improve and sustain weight loss following bariatric surgery. To support this premise, preliminary data on the relation between sleep duration and quality and long‐term weight change in a subsample of participants from the Longitudinal Assessment of Bariatric Surgery are presented. Results indicate a relation between sleep duration and BMI and percent weight loss 9 years after surgery. Additionally, sleep quality explained 25% of the variance in weight change between 6‐ and 9‐year follow‐up visits. These data from a small exploratory study, in combination with the known effects of sleep on energy balance, suggest that sleep may play an important role in both immediate and sustained weight loss following bariatric surgery. Herein, a model of the proposed bidirectional relation between sleep and weight loss is presented as well as a call for systematic investigations of the influence of sleep on long‐term weight management following bariatric surgery.

健康的睡眠能否改善长期减肥手术的效果？初步研究的结果并要求进一步研究。

健康的睡眠与较低的体重有关，并且可以改善减肥手术后的体重并维持体重减轻。为了支持这一前提，在减肥手术纵向评估的参与者子样本中提供了有关睡眠时间与质量和长期体重变化之间关系的初步数据。结果表明手术后9年睡眠时间与BMI和体重减轻百分比之间的关系。此外，睡眠质量解释了6年和9年随访期间体重变化的25％。来自一项小型探索性研究的这些数据，结合睡眠对能量平衡的已知影响，表明睡眠可能在减肥手术后的即刻和持续体重减轻中起重要作用。在此处，
