目的了解成都市成年人午睡习惯及夜晚睡眠时间与超重/肥胖的关系。方法采用横断面调查,以整群随机抽样的方法于2015年收集2015年成都市1276例(女性823人,男性453人) 20～70岁居民为研究对象。测量调查对象身高、体重,计算体质指数(BMI)以判断超重/肥胖;夜晚睡眠时间通过问题"你平均每晚的实际睡眠时间是多久"获得,午睡习惯通过问题"你一周睡几次午觉"获得。使用多元线性回归模型分析BMI与午睡习惯的关系,使用Logistic回归模型分析超重/肥胖与夜晚睡眠时间的关系。结果 66. 38%成都市成年人有午睡习惯,在调整了相关混杂因素后,有午睡习惯的人患超重/肥胖的风险低于无午睡习惯的人(OR=0. 69,95%CI0. 54～0. 88);青年组(<45岁)中,每周午睡次数增加1次,BMI减少0. 20;中年组(45～59岁)中,每周午睡次数增加1次,BMI减少0. 13;中年组的夜晚睡眠时间<6 h和6～6. 9 h的人患超重/肥胖的风险大于7～7. 9 h的人[OR=2. 11 (95%CI1. 20～3. 76),OR=1. 93(95%CI 1. 13～3. 34)]。结论成都市青年和中年人中,午睡次数与BMI呈现负相关关系,中年人夜晚睡眠时间短于7～7. 9 h可能是患超重/肥胖的危险因素。
Abstract：To examine whether nocturnal sleep duration and daytime napping are related to overweight/obesity among adults in Chengdu City. Methods A total of 1276 adults( women 823,men 453) aged 20-70 years were selected by randomized cluster sampling in 2015. The sleep duration rounded up to the hour was determined according to the answer to the question,"How much time do you usually sleep per night?",the nap time of subjects were collected according to the answer by the question,"How many days do you have a nap in a week?". Height and weight were measured to calculate body massindex. Logistic regression models were used to estimate the odd ratio( OR) and 95%confidence interval( 95% CI) of overweight/obesity. Results Approximately 66. 38% of subjects had daytime napping habit. After adjustment for potential confounders,OR( 95% CI) of overweight/obesity was 0. 69( 0. 54 – 0. 88) for nap takers compared with individuals without daytime napping habit. One nap increase in a week was associated with-0. 20,-0. 13 BMI in young adults and middle-aged adults. Very short nocturnal sleep duration( < 6 hours) and short nocturnal sleep duration( 6-6. 9 hours) was significantly associated with an increased risk of overweight/obesity among middle-aged adults OR = 2. 11( 95% CI 1. 20-3. 76),OR = 1. 93( 95% CI 1. 13-3. 34).Conclusion The frequency of daytime napping was negative associated with BMI among young and middle-aged adults. Short nocturnal sleep duration was associated with higher risk of overweight/obesity among middle-aged adults in Chengdu.
