Background: To explore the relationship between sleep disturbances and falls in an elderly Chinese population.Methods: Data from 1726 individuals aged 70-87 years from the Rugao Longevity and Ageing Study were used. The Pittsburgh Sleep Quality Index (PSQI) was used to assess sleep variables. Outcomes were falls >= 1 time per year and falls >= 2 times per year.Results: A total of 22.7% of the participants experienced >= 1 fall, and 9.8% experienced >= 2 falls per year. Poor sleep quality was associated with >= 1 fall (OR 1.08, 95% CI 1.05-1.12; OR 1.27, 95% CI 1.14-1.41) and >= 2 falls (OR 1.08, 95% CI 1.03-1.14; OR 1.28, 95% CI 1.10-1.48), with an increase per PSQI score and SD PSQI score, respectively. In addition, sleep quality, sleep latency, sleep efficiency, and sleep disturbance subcomponents were associated with an increased risk of >= 1 fall with ORs of 1.44 (95% CI, 1.21-1.72), 1.23 (95% CI, 1.09-1.40), 1.12 (95% CI, 1.01-1.23) and 1.70 (95% CI, 1.35-2.14), respectively, and were associated with an increased risk of >= 2 falls with ORs 1.54 (95% CI, 1.22-1.96), 1.21(95% CI, 1.02-1.44), 1.17 (95% CI 1.02-1.33), and 1.78 (95% CI, 1.31-2.44), respectively. Further, participants slept = 1 fall (OR 2.34; 95% CI, 1.59-3.46) and >= 2 falls (OR 2.19; 95% CI, 1.30-3.69).Conclusions: Poor sleep quality and several subcomponent sleep symptoms were consistently associated with increased risk of falls >= 1 time and >= 2 times in Chinese elderly. The identification of sleep disturbances may help identify high-risk Chinese elders who may benefit from fall prevention education.
