abstract="OBJECTIVE: To explore the independent and joint associations of sleep duration, midday napping, and depression with fall accidents in Chinese postmenopausal women. <br><br>METHODS: A total of 2,378 postmenopausal women aged ≥ 45 years from the baseline  survey of the China Health and Retirement Longitudinal Study were enrolled in the  study. Each participant provided data on falls, sleep duration, midday napping by a  self-reporting approach. We employed the Chinese version of the Center for  Epidemiologic Studies Depression Scale to assess depression. Adjusted odds ratios  (OR) and 95% confidence intervals (CI) were calculated to estimate the associations  of predictor variables with falls using multivariate logistic regression. <br><br>RESULTS:  Of the 2,378 postmenopausal women, 478 (20.10%) reported falls in the preceding 2  years. Compared with sleep duration of 7 to 8 h/night, sleep duration of 5 to  6 h/night (OR, 1.49; 95% CI, 1.03-2.15) and of ≤ 5 h/night (OR, 1.63; 95% CI,  1.18-2.25) were associated with a higher fall prevalence. However, no significant  correlation was found between sleep duration of > 8 h/night and falls. Furthermore,  participants with depression were more likely to report falls (OR, 1.78; 95% CI,  1.41-2.25) than their depression-free counterparts. The duration of midday napping  was not independently associated with falls, but significant joint associations of  sleeping ≤ 6 h/night and no napping (OR, 1.72; 95% CI, 1.07-2.76) or napping >  60 minutes (OR, 2.14; 95% CI, 1.18-3.89) with more falls were found. Similarly, a  combined status of sleeping ≤ 6 h/night and depression was related to more falls  (OR, 2.97; 95% CI, 1.86-4.74). <br><br>CONCLUSION: The present study demonstrates that short  sleep duration and depression are independently associated with more falls among  postmenopausal women in China. Moreover, short sleep duration combined with no or  long napping, short sleep duration combined with depression are jointly correlated  with more falls. Future longitudinal studies are warranted to confirm these  findings.<p /> <p>Language: en</p>",
