Abstract
Objective: This is a meta-analysis of the pooled prevalence of insomnia-specific sleep disturbances (sleep disturbances thereafter) and sleep qualityin older Chinese adults.Method: Both English (PubMed, Embase andPsycINFO) and Chinese (Chinese National Knowledge Infrastructure [CNKI],WanFang and SinoMed) databases were systematically searched. Dataextraction and quality assessment were independently performed by twoinvestigators. Random-effects model was performed to pool the prevalenceof sleep disturbances and sleep quality. Subgroup and meta-regressionanalyses were performed to explore the source of heterogeneity. Funnelplots, Egger’s regression model, and Begg’s test were used to assess pub-lication bias.Results: A total of 47 studies were included. The pooledprevalence of sleep disturbances was 35.9% (95% CI: 30.6%–41.2%). Olderadults in rural areas had higher prevalence of sleep disturbances than theircounterparts in urban areas. Sleep quality was measured by the PittsburghSleep Quality Assessment (PSQI) in all studies with available data. In the 27studies with available data, the pooled mean PSQI total score was 6.64 (95%CI: 6.14–7.13). There was no significant difference between genders andbetween rural and urban areas. Compared to men, women had highermean scores in sleep latency (Q = 23.62,p< 0.001), sleep efficiency(Q = 12.08,p= 0.001), and use of sleep-promoting medications (Q = 4.07,p= 0.044).Conclusion: Sleep disturbances are common in older Chineseadults, particularly in older women.
