This study investigated the total sleep time (TST) and its associated factors in an older Chinese adult population. Multistage stratified cluster sampling was used in this cross-sectional study. A total of 4,115 older adults aged 60 to 79 years were selected and interviewed. Sleep duration was classified as short (<7h per day), long (>8h per day) and medium sleep (7-8h per day). The total mean sleep time was 6.86±1.75h. Short and long sleepers accounted for 45.2% and 14.8% of the sample, respectively. Multivariate logistic regression analysis revealed that inadequate fruit intake and poor mental health were positively associated with short sleep, and married/cohabitation status and living in rural areas was negatively associated with short sleep. In addition, aged 75-79 years old, inadequate fruit intake, poor mental health and multi-morbidity were positively associated with long sleep. Ischemic heart disease, COPD and chronic gastroenteritis/peptic ulcer were positively associated with short sleep duration, while hyperlipidemia, hypertension, cerebrovascular diseases, and urolithiasis were positively associated with long sleep duration. Given the high frequency of aberrant sleep duration and its negative health impact, health professionals should pay more attention to sleep patterns in older people.
本研究调查了老年中国成年人的总睡眠时间（TST）及其相关因素。这项横断面研究采用多阶段分层聚类抽样。共选取 4115 名 60-79 岁的老年人进行访谈。睡眠时间分为短（每天<7 小时）、长（每天>8 小时）和中（每天 7-8 小时）。总平均睡眠时间为 6.86±1.75 小时。短睡者和长睡者分别占样本的 45.2%和 14.8%。多变量逻辑回归分析显示，水果摄入不足和心理健康不良与短睡眠呈正相关，已婚/同居状态和居住在农村地区与短睡眠呈负相关。此外，75-79 岁、水果摄入不足、心理健康不良和多种合并症与长睡眠呈正相关。缺血性心脏病、COPD 和慢性胃肠炎/消化性溃疡与短睡眠时间呈正相关，而高血脂、高血压、脑血管疾病和尿路结石与长睡眠时间呈正相关。鉴于异常睡眠时间的高频率及其对健康的负面影响，卫生专业人员应更加关注老年人的睡眠模式。
