贵州省成年居民睡眠状况及影响因素分析

目的了解贵州省成年居民睡眠状况及其影响因素, 为改善睡眠质量, 促进人群健康睡眠提供科学依据。方法采用多阶段分层随机抽样方法对在贵州省抽取的9 280名≥18岁成年居民进行问卷调查。结果贵州省成年居民平均睡眠时间为(7.90±1.34)h;城市居民平均睡眠时间为(7.77±1.34)h, 低于农村居民的(7.96±1.34)h(t=-6.478, P=0.000);男、女性居民平均睡眠时间分别为(7.89±1.30)、(7.91±1.37)h, 差异无统计学意义(P>0.05);18~24、25~34、35~44、45~54、55~64和≥65岁居民平均睡眠时间分别为(8.17±1.11)、(8.12±1.13)、(7.95±1.22)、(7.80±1.34)、(7.67±1.50)和(7.66±1.71)h, 睡眠时间与年龄呈负相关(r=-0.135, P=0.000);多因素非条件logistic回归分析结果显示, 居住在农村、年龄≥25岁、职业为脑力劳动者和饮酒是贵州省成年居民睡眠不足的危险因素, 文化程度初中及以上和经常锻炼是贵州省成年居民睡眠不足的保护因素。结论贵州省成年居民睡眠时间较少, 年龄、文化程度、职业、饮酒、锻炼是贵州省成年居民睡眠不足的影响因素。

Sleep pattern and its influencing factors among adult residents in Guizhou province

ObjectiveTo explore the pattern and influencing factors of sleep among adult residents in Guizhou province and to provide scientific evidences for improving sleep quality of the residents.MethodsA questionnaire survey was conducted among 9 280 adult residents at the age of 18 years and older selected with multistage stratified random sampling in Guizhou province.ResultsThe average sleep time of the residents was 7.90±1.34 hours; the urban residents had a significantly less average sleep time than rural residents(7.77±1.34 vs. 7.96±1.34 hours)(t=-6.478,P=0.000) and the average sleep time of the male residents was not significantly different from that of female residents(7.89±1.30 vs. 7.91±1.37 hours)(P>0.05).The average sleep time for the residents at the ages of 18-24,25-34,35-44,45-54,55-64,and ≥65 years were 8.17±1.11,8.12±1.13,7.95±1.22,7.80±1.34,7.67±1.50,and 7.66±1.71 hours and the average sleep time was negatively correlated to age(r=-0.135,P=0.000).Unconditioned logistic regression analyses showed that living in rural area,aged ≥25 years,being a mental worker,and alcohol drinking were the risk factors for insufficient sleep time; with the education of junior high school or higher and frequent physical exercise were protective factors of sufficient sleep time among the residents.ConclusionThe adult residents in Guizhou province have a less sleep time and age,education level,occupation,alcohol drinking,and physical exercise are major influencing factors of sleep quality in the residents.
