This meta-analysis examined the mean sleep duration and patterns in Chinese older adult population. A literature search was systematically conducted covering major English (PubMed, Embase and PsycINFO) and Chinese (Chinese National Knowledge Infrastructure (CNKI), WanFang and SinoMed) databases. Data in studies with the mean and standard deviation of sleep duration and/or the proportion of short and long sleep durations in Chinese older adults were extracted and pooled using random-effects models. Subgroup analyses were conducted according to gender, region, area, survey time and sample size. A total of 36 studies with 150,616 subjects were included for analyses. The pooled mean sleep duration of 21 studies with available data was 6.82 hours/day (95% CI: 6.59-7.05 hours/day). The estimated proportions of sleep duration <5 hours/day, <6 hours/day, <7 hours/day were 18.8% (95% CI: 1.7%-35.9%), 26.7% (95% CI: 19.7%-33.7%) and 42.3% (95% CI: 34.8%-49.8%), respectively. The pooled proportions for long sleepers were 22.6% (95% CI: 13.9%-31.4%) (>8 hours/day) and 17.6% (95% CI: 12.4%-22.9%) (>9 hours/day). Given the adverse effects of unhealthy sleep patterns, health professionals should pay more attention to sleep patterns in this population in China.
这项荟萃分析研究了中国老年人群的平均睡眠时间和睡眠模式。系统地检索了主要英文数据库（PubMed、Embase和PsycINFO）和中文数据库（中国知网、万方和维普）。提取了有关中国老年人睡眠持续时间的均值和标准差及/或短睡眠和长睡眠持续时间比例的研究数据，并使用随机效应模型进行汇总。根据性别、地区、区域、调查时间和样本量进行亚组分析。共纳入36项研究，涉及150,616名受试者进行分析。21项有可用数据的研究汇总平均睡眠时间为6.82小时/天（95%置信区间：6.59 - 7.05小时/天）。估计睡眠时间<5小时/天、<6小时/天、<7小时/天的比例分别为18.8%（95%置信区间：1.7% - 35.9%）、26.7%（95%置信区间：19.7% - 33.7%）和42.3%（95%置信区间：34.8% - 49.8%）。长睡眠者（>8小时/天）的汇总比例为22.6%（95%置信区间：13.9% - 31.4%），（>9小时/天）为17.6%（95%置信区间：12.4% - 22.9%）。鉴于不健康睡眠模式的不良影响，中国的卫生专业人员应更加关注该人群的睡眠模式。
