Sleep disorders are common health problems in the elderly. The effect of social isolation on sleep duration and sleep quality remains unclear in the Chinese community-dwelling elderly.
To explore the associations of social isolation with sleep duration and sleep quality in community-dwelling elderly people.
A total of 7762 community-dwelling elderly people aged 60 years and older in Ningbo were recruited from June 2022 to August 2022. Data were collected using a questionnaire. Multivariate logistic regression was used to analyze the associations of social isolation with sleep duration and sleep quality. The KHB mediating effect model was used to test the mediating effect of depression and anxiety on these associations.
Among the participants, 2656 (34.2%) had abnormal sleep duration (< 6 hours or > 8 hours), 1115 (14.4%) had poor sleep quality, and 917 (11.8%) had social isolation. After adjusting for confounding factors, compared with the elderly without social isolation, the odds ratios (95%CI) of abnormal sleep duration and poor sleep quality in the elderly with social isolation were 1.49 (1.29-1.73) and 1.32 (1.09-1.59), respectively. Depression partially mediated the associations of social isolation with sleep duration and sleep quality, accounting for 5.68% and 9.87% of the mediating effect, respectively.
Social isolation was found to be associated with sleep duration and sleep quality in community-dwelling elderly people. More attention should be paid to social isolation in the elderly.
睡眠障碍是老年人常见的健康问题。在中国社区居住的老年人中，社会隔离对睡眠时间和睡眠质量的影响尚不清楚。
探讨社区居住老年人中社会隔离与睡眠时间和睡眠质量之间的关联。
2022年6月至2022年8月，共招募了7762名年龄在60岁及以上的宁波社区居住老年人。使用问卷调查收集数据。采用多因素logistic回归分析社会隔离与睡眠时间和睡眠质量之间的关联。使用KHB中介效应模型检验抑郁和焦虑在这些关联中的中介作用。
在参与者中，2656人（34.2%）睡眠时间异常（<6小时或>8小时），1115人（14.4%）睡眠质量差，917人（11.8%）存在社会隔离。在调整混杂因素后，与无社会隔离的老年人相比，有社会隔离的老年人睡眠时间异常和睡眠质量差的比值比（95%CI）分别为1.49（1.29 - 1.73）和1.32（1.09 - 1.59）。抑郁部分介导了社会隔离与睡眠时间和睡眠质量之间的关联，分别占中介效应的5.68%和9.87%。
发现社会隔离与社区居住老年人的睡眠时间和睡眠质量有关。应更加关注老年人的社会隔离问题。
