中国60岁及以上老年人睡眠与焦虑的关联研究

目的探讨我国≥60岁老年人睡眠时长、睡眠质量与焦虑状态之间的关联。方法研究纳入"我国大气污染的急性健康风险研究"项目2017年7月18日至2018年2月7日调查的≥60岁老年人,采用多因素logistic回归模型分析睡眠时长、睡眠质量与焦虑之间的关联。结果共纳入3897名≥60岁老年人,年龄为(73.4±8.0)岁,焦虑者占6.5%;睡眠质量差者占18.7%。多因素logistic回归模型显示,在调整一般人口学、社会经济因素、生活方式、健康状况、社会支持程度及大气PM2.5暴露等因素后,睡眠时间过短是老年人焦虑的危险因素,与睡眠时长7 h者相比,睡眠时长≤6 h者焦虑的OR值(95%CI)为2.09(1.49~2.93)。与睡眠质量好者相比,睡眠质量差者焦虑的OR值(95%CI)为5.12(3.88~6.77)。匹兹堡睡眠质量指数量表各条目评分升高与焦虑均存在统计学关联,其中睡眠障碍、主观睡眠质量和日间功能障碍与焦虑的关联更强,OR值(95%CI)分别为4.63(3.55~6.04)、2.75(2.33~3.23)和2.50(2.19~2.86)。亚组分析显示男性、<80岁老年人的睡眠时长、睡眠质量与焦虑的关联更强。结论睡眠时间较短和睡眠质量差与老年人焦虑风险相关。

Association of sleep with anxiety in the elderly aged 60 years and older in China

Objective To investigate the relationship of sleep duration and sleep quality with anxiety in the elderly aged 60 years and older in China.Methods 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.Results A total of 3897 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 OR(95%CI)of anxiety for those with sleep duration≤6 hours was 2.09(1.49-2.93).Compared with those with good sleep quality,the OR(95%CI)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 ORs(95%CI)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.Conclusion Shorter sleep duration and poor sleep quality are associated with anxiety in the elderly in China.
