PURPOSE
Sleep impairment is reported to be a consequence of overweight and obesity. However, the weight-sleep relationship can alternately be explained by demographics (e.g. age) and covariates (i.e. mood/affect and behaviour in overweight/obese people; e.g. night-eating). Thus, we examined the weight-sleep quality relationship after controlling for the effects of affect and common behaviour (i.e. night-eating, insufficient exercise, alcohol and electronic device use).
METHODS
Online questionnaires asked 161 overweight, obese or normal-weight participants about their sleep quality, night-eating, physical activity, alcohol use, electronic device use and anxiety and depression at T0 (baseline) and T1 (3 months later). Height and weight and waist and hip circumference were objectively measured at T0 and T1, and physical activity was assessed over 24 h (using actigraphy) at T0 and T1. Hierarchical multiple regression analyses evaluated whether the weight measures (i.e. body-mass-index [BMI], waist-to-hip ratio [WHR] and obesity category [overweight/obese vs. normal-weight]) predicted sleep quality and its components at T0 and T1, after controlling demographics (at step 1) and covariates (affective distress and behaviour) at step 2, and entering weight measures at step 3; maximum 8 variables in the analyses.
RESULTS
High BMI predicted several aspects of sleep quality after taking into account co-existing behaviour, affect and demographics: sleep disturbances at T0 and lower sleep efficiency at T1. WHR and obesity category did not predict any aspects of sleep quality. Several co-existing behaviour were related to or predicted sleep quality score and aspects of sleep quality including night-eating, alcohol use and electronic device use and affective symptoms (i.e. anxiety, depression).
CONCLUSION
Results suggest that a person's weight may impact on their sleep quality above and beyond the effects of their co-existing behaviour and affect, although their co-existing behaviour and affect may also adversely impact on sleep quality.
LEVEL OF EVIDENCE
Level III, evidence obtained from well-designed cohort.
目的
据报道，超重和肥胖会导致睡眠障碍。然而，体重与睡眠之间的关系也可以通过人口统计学因素（例如年龄）和协变量（即超重/肥胖人群的情绪/情感和行为；例如夜间进食）来解释。因此，我们在控制情绪和常见行为（即夜间进食、运动不足、饮酒和电子设备使用）的影响后，检查了体重与睡眠质量之间的关系。
方法
在线问卷询问了 161 名超重、肥胖或正常体重的参与者关于他们的睡眠质量、夜间进食、身体活动、饮酒、电子设备使用以及在 T0（基线）和 T1（3 个月后）的焦虑和抑郁情况。在 T0 和 T1 时客观测量身高、体重、腰围和臀围，并在 T0 和 T1 时使用活动记录仪评估 24 小时的身体活动。分层多元回归分析评估了体重指标（即 BMI、腰臀比 [WHR] 和肥胖类别 [超重/肥胖与正常体重]）是否可以预测 T0 和 T1 时的睡眠质量及其组成部分，在控制人口统计学因素（第 1 步）和协变量（情绪困扰和行为）后第 2 步，并在第 3 步中输入体重指标；分析中最多有 8 个变量。
结果
在考虑到共存行为、情绪和人口统计学因素后，高 BMI 预测了睡眠质量的几个方面：T0 时的睡眠障碍和 T1 时的睡眠效率较低。WHR 和肥胖类别不能预测睡眠质量的任何方面。一些共存的行为与睡眠质量评分和睡眠质量的几个方面有关，包括夜间进食、饮酒和电子设备使用以及情绪症状（即焦虑、抑郁）。
结论
结果表明，一个人的体重可能会对他们的睡眠质量产生影响，超出其共存行为和情绪的影响，尽管他们的共存行为和情绪也可能对睡眠质量产生不利影响。
