摘要/Abstract

摘要： 目的了解我国成年人超重肥胖流行现状,探讨成年人午睡时长、夜间睡眠时长与超重肥胖的关系。方法数据来源于2020年中国家庭追踪调查（CFPS）数据库,使用频数和百分比对超重肥胖进行一般统计描述,采用二元logistic回归和限制性立方样条图探讨午睡时长、夜间睡眠时长与成人超重肥胖的相关关系和非线性关系。结果本研究纳入有效样本20 955人,超重肥胖率、有午睡习惯率和夜间睡眠不足率分别为38.8%（8 137/20 955）、61.1%（12 806/20 955）、20.4%（4 279/20 955）。控制混杂因素后,相较于不午睡,午睡30~<60 min（OR=1.105）、60~<90 min（OR=1.143）、≥90 min（OR=1.207）与超重肥胖发生存在关联;相较于夜间睡眠时长7~9 h,夜间睡眠时长<7 h与超重肥胖发生存在关联（OR=1.168）。限制性立方样条图结果显示,午睡时长30 min和夜间睡眠时长8 h为临界点,午睡时长>30 min、夜间睡眠时长<8 h与超重肥胖发生风险升高相关。性别分层结果显示,男性在午睡30~<60 min（OR=1.256）、≥90 min（OR=1.146）与超重肥胖相关,女性在午睡60~<90 min（OR=1.204）、≥90 min（OR=1.346）与超重肥胖相关;男性（OR=1.155）和女性（OR=1.166）在夜间睡眠时长<7 h与超重肥胖相关。性别与午睡时长30~<60 min、60~<90 min、≥90 min和夜间睡眠时长<7 h存在交互作用（P<0.05或P<0.01）。结论延长午睡时长、夜间睡眠时长不足与成人超重肥胖密切相关,午睡时长对成人超重肥胖影响有待进一步研究。

Abstract: Objective To understand the prevalence of overweight/obesity among Chinese adults,and to explore the relationship between nap duration,nighttime sleep duration and overweight/obesity. Methods Data were collected from the 2020 China Family Panel Studies （CFPS） database. Frequency and percentage were used to conduct general statistical description of overweight and obesity. Binary logistic regression and restricted cubic spline were used to explore the relationship and nonlinear relationship between nap duration,nighttime sleep duration and overweight/obesity in adults. Results A valid sample of 20 955 individuals was included in this study,and the rates of overweight/obesity,napping habit,and insufficient nighttime sleep were 38.8% （8 137/20 955）,61.1% （12 806/20 955）,and 20.4% （4 279/20 955）,respectively. After controlling for confounders,nap duration 30~<60 min （OR=1.105）,60~<90 min （OR=1.143）,and ≥90 min （OR=1.207） was associated with overweight/obesity compared with no napping. Compared with nighttime sleep duration of 7-9 h,nighttime sleep duration<7 h was associated with overweight/obesity （OR=1.168）. The results of the restricted cubic spline showed that 30 min of nap duration and 8 h of nighttime sleep duration were the critical points,nap duration >30 min and nighttime sleep duration <8 h were associated with an increased risk of overweight and obesity. The results of gender stratification showed that the nap duration 30~<60 min （OR=1.256） and ≥90 min （OR=1.146） were associated with overweight/obesity in men,and the nap duration 60~<90 min （OR=1.204） and ≥90 min （OR=1.346） were associated with overweight/obesity in women. Nighttime sleep duration<7 h was associated with overweight and obesity in men （OR=1.155） and women （OR=1.166）. There was an interaction between gender and nap duration 30~<60 min,60~<90 min,≥90 min,and nighttime sleep duration<7 h （P<0.05 or P<0.01）. Conclusion Prolonged nap duration and insufficient nighttime sleep duration were closely associated with overweight/obesity in adults,and the effect of nap duration on overweight/obesity in adults needs further study.
