To investigate the relationship of sleep duration and sleep quality with anxiety in the elderly aged 60 years and older in China. The elderly aged 60 years and older were selected from the China Short-term Health Effects of Air Pollution Study conducted between July 18, 2017 and February 7, 2018. Multivariate logistic regression models were used to analyze the association of sleep duration and sleep quality with anxiety. A total of 3 897 elderly aged 60 years and older were included in the study. The age of the elderly was (73.4±8.0) years old. Among the elderly surveyed, 6.5 were defined with anxiety, and 18.7 reported poor sleep quality. Multivariate logistic regression models showed shorter sleep duration was the risk factor for anxiety in the elderly that after adjusting for factors such as general demographics, socioeconomic factors, lifestyle, health status, social support and ambient fine particulates exposure. Compared with the elderly with 7 hours of sleep duration daily, the (95) of anxiety for those with sleep duration ≤ 6 hours was 2.09 (1.49-2.93). Compared with those with good sleep quality, the (95) of anxiety for those with poor sleep quality was 5.12 (3.88-6.77). We also found statistically significant correlations of the scores of subscales of Pittsburgh sleep quality index with anxiety, in which the effects of sleep disturbance, subjective sleep quality and daytime dysfunction scores were most obvious, the (95) were 4.63 (3.55-6.04), 2.75 (2.33-3.23) and 2.50 (2.19-2.86), respectively. Subgroup analysis showed that the association of sleep duration and sleep quality with anxiety was more obvious in males and in those aged <80 years. Shorter sleep duration and poor sleep quality are associated with anxiety in the elderly in China.
为研究中国60岁及以上老年人的睡眠时间和睡眠质量与焦虑之间的关系。从2017年7月18日至2018年2月7日进行的中国空气污染短期健康影响研究中选取60岁及以上的老年人。采用多因素logistic回归模型分析睡眠时间和睡眠质量与焦虑的关联。本研究共纳入3897名60岁及以上的老年人。老年人年龄为（73.4±8.0）岁。在接受调查的老年人中，6.5%被定义为有焦虑，18.7%报告睡眠质量差。多因素logistic回归模型显示，在调整了一般人口统计学、社会经济因素、生活方式、健康状况、社会支持和环境细颗粒物暴露等因素后，较短的睡眠时间是老年人焦虑的危险因素。与每天睡眠时间为7小时的老年人相比，睡眠时间≤6小时的老年人焦虑的（95）为2.09（1.49 - 2.93）。与睡眠质量好的老年人相比，睡眠质量差的老年人焦虑的（95）为5.12（3.88 - 6.77）。我们还发现匹兹堡睡眠质量指数各子量表得分与焦虑之间存在统计学显著相关性，其中睡眠障碍、主观睡眠质量和日间功能障碍得分的影响最为明显，（95）分别为4.63（3.55 - 6.04）、2.75（2.33 - 3.23）和2.50（2.19 - 2.86）。亚组分析显示，睡眠时间和睡眠质量与焦虑的关联在男性和80岁以下人群中更为明显。在中国老年人中，较短的睡眠时间和较差的睡眠质量与焦虑有关。
