BACKGROUND
Poor sleep and history of weight cycling (HWC) are associated with worse cardiovascular health, yet limited research has evaluated the association between HWC and poor sleep patterns.
METHODS
The American Heart Association Go Red for Women Strategically Focused Research Network cohort at Columbia University (n = 506; mean age, 37 ± 15.7 years; 61% racial/ethnic minority) was used to evaluate the cross-sectional associations of HWC and sleep at baseline and the prospective associations of HWC from baseline with sleep at the 1-year visit. History of weight cycling, defined as losing and gaining 10 lb or more at least once (excluding pregnancy), was self-reported. Sleep duration, sleep quality, insomnia severity, and obstructive sleep apnea risk were assessed using the validated Pittsburgh Sleep Quality Index, Insomnia Severity Index, and Berlin questionnaires. Linear and logistic regression models, adjusted for age, race/ethnicity, education, health insurance status, pregnancy history, and menopausal status, were used to evaluate the relation of HWC with sleep.
RESULTS
Most women reported 1 or more episodes of weight cycling (72%). In linear models of cross-sectional and prospective data, each additional weight cycling episode was related to shorter sleep duration, poorer sleep quality, longer sleep onset latency, greater insomnia severity, more sleep disturbances, lower sleep efficiency, and higher sleep medication use frequency. In the logistic models, HWC (≥1 vs 0 episodes) was associated with greater odds for short sleep, poor sleep quality, long sleep onset latency (≥26 minutes), high obstructive sleep apnea risk, and sleep efficiency lower than 85%.
CONCLUSION
History of weight cycling predicted poor sleep among women, suggesting that weight maintenance may represent an important strategy to promote sleep health. The potential bidirectional relationship between HWC and sleep requires further investigation.
背景
睡眠质量差和体重循环史（HWC）与心血管健康状况较差有关，但很少有研究评估 HWC 与不良睡眠模式之间的关系。
方法
哥伦比亚大学美国心脏协会 Go Red for Women 战略性重点研究网络队列（n=506；平均年龄 37±15.7 岁；61%为少数民族/族裔）用于评估基线时 HWC 和睡眠的横断面关联，以及基线时 HWC 与 1 年随访时睡眠的前瞻性关联。体重循环史定义为至少一次失去和增加 10 磅或更多（不包括怀孕），由自我报告。使用经过验证的匹兹堡睡眠质量指数、失眠严重程度指数和柏林问卷评估睡眠持续时间、睡眠质量、失眠严重程度和阻塞性睡眠呼吸暂停风险。线性和逻辑回归模型，调整了年龄、种族/族裔、教育程度、健康保险状况、怀孕史和绝经状态，用于评估 HWC 与睡眠的关系。
结果
大多数女性报告有 1 次或多次体重循环（72%）。在横断面和前瞻性数据的线性模型中，每次额外的体重循环与睡眠持续时间缩短、睡眠质量下降、入睡潜伏期延长、失眠严重程度增加、睡眠障碍增多、睡眠效率降低以及睡眠药物使用频率增加有关。在逻辑模型中，HWC（≥1 次与 0 次）与短睡眠、睡眠质量差、入睡潜伏期长（≥26 分钟）、高阻塞性睡眠呼吸暂停风险和睡眠效率低于 85%的可能性更大有关。
结论
体重循环史预测了女性的睡眠质量差，表明体重维持可能是促进睡眠健康的重要策略。HWC 和睡眠之间的潜在双向关系需要进一步研究。
