目的：睡眠与肥胖（通过体重指数或腰臀比来衡量）之间的关联通常是使用单一维度的自我报告睡眠来评估的。然而，睡眠的其他维度和行为指标可能也与肥胖有关。本研究评估了在睡眠障碍和肥胖患病率较高的中年女性样本中，通过活动记录仪和自我报告计算出的多维睡眠健康是否与肥胖存在纵向关联。
设计：在睡眠健康评估与体重指数/腰臀比测量之间有11 - 14年随访时间的纵向研究。
参与者：221名参与全国女性健康研究睡眠研究的中年女性。
测量：使用活动记录仪（平均[标准差] = 29.1[7.2]晚）对睡眠效率、中点、时长、规律性进行测量，并使用自我报告的警觉性和满意度进行测量，以此对多维睡眠健康进行量化。每个组成部分都进行二分并求和；数值越高表明睡眠健康越好。在睡眠研究和随访时测量身高、体重以及腰围和臀围。使用线性回归模型评估睡眠健康与肥胖之间的关联，并对人口统计学和更年期协变量进行调整。
结果：随着时间推移，个体的肥胖程度没有实质性变化。在未调整的模型中，较好的睡眠健康与较低的肥胖程度在横断面和纵向都有关联，但在调整后的模型中则无关联。在调整后，单个睡眠健康组成部分与肥胖无关。
结论：我们没有观察到多维睡眠健康与肥胖之间存在横断面或纵向关联。中年成年人的睡眠 - 肥胖关联可能比其他年龄组更弱。（C）2020美国国家睡眠基金会。由爱思唯尔公司出版。保留所有权利。
Objectives: The association between sleep and adiposity (indexed by body mass index or waist-to-hip ratio) has typically been evaluated using a single dimension of self-reported sleep. However, other dimensions and behavioral measures of sleep may also be associated with adiposity. This study evaluated whether multidimensional sleep health calculated from actigraphy and self-report was longitudinally associated with adiposity in a sample of midlife women who have a high prevalence of sleep disturbances and adiposity.Design: Longitudinal study with 11-14 years of follow-up time between the sleep health assessment and body mass index/waist-to-hip ratio measurements.Participants: Two hundred and twenty-one midlife women enrolled in the Study of Women's Health Across the Nation Sleep Study.Measurements: Multidimensional sleep health was quantified using actigraphy (M[SD] = 29.1[7.2] nights) measures of sleep efficiency, midpoint, duration, regularity, and self-report measures of alertness and satisfaction. Each component was dichotomized and summed; higher values indicated better sleep health. Height, body weight, and waist and hip circumference were measured at the sleep study and at follow-up. Linear regression models were used to assess associations between sleep health and adiposity, adjusting for demographic and menopausal covariates.Results: There was no substantial within-person change in adiposity over time. Better sleep health was cross-sectionally and longitudinally associated with lower adiposity in unadjusted, but not in adjusted, models. Individual sleep health components were not associated with adiposity after adjustment.Conclusion: We did not observe cross-sectional or longitudinal associations between multidimensional sleep health and adiposity. The sleep-adiposity link may be weaker in midlife adults than in other age groups. (C) 2020 National Sleep Foundation. Published by Elsevier Inc. All rights reserved.
