This survey investigated the prevalence, distribution, and correlative factors of insomnia symptoms among people aged 65 and above in Guangdong Province, China.
The Guangdong Mental Health Survey was conducted on the elderly in all 21 cities of Guangdong Province from September to December 2021. Multistage stratified cluster sampling was adopted, and 16 377 adult residents were interviewed face-to-face, from which 4001 elderly participants aged 65 and above were included for this study. Complex weighted adjustment methods were applied to weight the data. Multinomial logistic regression was applied to test the independent associations of clinical insomnia symptoms (CIS) and subthreshold insomnia symptoms (SIS) with the factors.
The pooled estimate of insomnia symptoms was 13.44% [95% confidence interval (CI): 12.2 %-14.7%]. The 1-month weighted prevalence of SIS and CIS were 11.15% (95% CI: 10.05%-12.37%) and 2.28% (95%CI: 1.77%-2.94%), respectively. Multinomial logistic regression analysis revealed that urban residence, irregular diet, low body mass index, chronic disease, napping 3-4/week, early changes in dementia, symptoms of subthreshold depression, subthreshold generalized anxiety, and generalized anxiety disorder were positively associated with SIS. Additionally, living in urban areas, having chronic diseases, symptoms of subthreshold depression, major depressive disorder, subthreshold generalized anxiety, generalized anxiety disorder were positively associated with CIS.
Insomnia symptoms, including CIS and SIS, were prevalent among the elderly in Guangdong Province. Given the high burden of CIS and SIS, policymakers and healthcare professionals must explore and treat the related factors accordingly.
本调查研究了中国广东省65岁及以上人群失眠症状的患病率、分布情况及相关因素。
2021年9月至12月，在广东省所有21个城市对老年人开展了广东心理健康调查。采用多阶段分层整群抽样法，面对面访谈了16377名成年居民，其中4001名65岁及以上的老年参与者纳入本研究。应用复杂加权调整方法对数据进行加权。采用多项逻辑回归分析检验临床失眠症状（CIS）和阈下失眠症状（SIS）与各因素的独立关联。
失眠症状的合并估计患病率为13.44%[95%置信区间（CI）：12.2%-14.7%]。SIS和CIS的1个月加权患病率分别为11.15%（95%CI：10.05%-12.37%）和2.28%（95%CI：1.77%-2.94%）。多项逻辑回归分析显示，居住在城市、饮食不规律、低体重指数、慢性病、每周午睡3-4次、痴呆早期变化、阈下抑郁症状、阈下广泛性焦虑和广泛性焦虑障碍与SIS呈正相关。此外，居住在城市地区、患有慢性病、阈下抑郁症状、重度抑郁症、阈下广泛性焦虑、广泛性焦虑障碍与CIS呈正相关。
包括CIS和SIS在内的失眠症状在广东省老年人中普遍存在。鉴于CIS和SIS的高负担，政策制定者和医疗保健专业人员必须探索并相应地治疗相关因素。
