Sleep disorders causes a significant negative effect on mental and physical health, particularly among the elderly. The disease burden and risk factors of poor sleep quality of the elderly need to be verified using a validated form of measurement in urban mainland China. This study included 1086 community residents aged ≥ 60 years who completed the Chinese version of the Pittsburgh Sleep Quality Index (CPSQI). Poor sleeper was defined by a CPSQI global score of >5. Subjects also accepted the neurological and neuropsychological assessments, including the Mini-Mental State Examination, Center for Epidemiological Studies Depression Scale, and Zung Self-Rating Anxiety Scale (ZSAS). A history of chronic diseases was confirmed by the medical records of each participant. The prevalence of poor sleep quality in this population was 41.5% (95% confidence interval (CI) = 38.6-44.5%), with a higher rate observed in elderly females (45.8% [95% CI = 41.9-49.7%]) than that in elderly males (35.8% [95% CI = 31.4-40.1%]). The prevalence rate increased with age, from 32.1% (95% CI = 27.8-36.4%) in those aged 60-69 years to 52.5% (95% CI = 45.9-59.1%) in those aged ≥ 80 years (p value for trend
