Introduction: Work schedules that contain long shifts, mandatory over-time, and quick returns (work with <10 hours between shifts) can influence the quality and amount of sleep amount obtained. Excessive work demands also can produce slow unwinding, interfering with sleep quality. In addition, home demands can also interfere with obtaining needed rest. This study describes the association between work schedules and home demands on restless or insufficient sleep in a large population-based sample of registered nurses (RNs. Methods: Data were analyzed from Wave 1 of a longitudinal survey of RNs (N= 2273). Work schedule variables included hours per day and per week, days per week, weekends/month, shift typically worked, quick returns, mandatory overtime, on-call, and circadian mismatch. Sleep was measured by two items: "My sleep was restless" and "I got less sleep than I thought I should" with responses dichotomized to 3 or more nights per week as the indicator. Respondents were also asked about home demands including time spent on childcare, dependent elderly care, and domestic chores. Bivariate odds were estimated for each work schedule item in relation to sleep. Results: Restless sleep was predicted by workdays > 12 hours long (OR 1.56, 95% CI 1.11-2.19), quick returns (1.66, 1.03-2.69), and mandatorty overtime at least weekly (1.63- 1.17-2.26). Insufficient sleep was predicted by nightshift (1.63, 1.17-2.27), weekend work (OR 1.33-1.46 by frequency) quick returns (OR 1.61 to 2.04 by frequency), mandatory overtime (1.49, 1.09-2.05), and circadian mismatch (OR 1.51, 1.22- 1.87). Child and eldercare and household chores also interfered with sleep. Conclusion: Sleep quality and amount were negatively influenced by adverse work schedules and additional home demands. These results have implications for both worker and patient safety, as sleep adequacy affects job performance.
