abstract="BACKGROUND: This study was designed to identify potential effects of workload and sleep on injury occurrence. <br><br>METHODS: Questionnaires were disseminated to janitors in the SEIU Local 26 union; 390 responded and provided information on workload, sleep, and injury outcomes. Quantitative measurements of workload and sleep were collected via FitBit devices from a subset of 58 janitors. Regression techniques were implemented to determine risk. <br><br>RESULTS: Thirty-seven percent reported increased workload over the study period Adjusted analyses indicated a significant effect of change in workload (RR: 1.94; 95%CI: 1.40-2.70) and sleep hours (RR: 2.21; 95%CI: 1.33-3.66) on occupational injury. Among those with sleep disturbances, injury risk was greater for those with less than five, versus more than five, days of moderate to vigorous physical activity; RR: 2.77; 95%CI: 1.16-6.59). <br><br>CONCLUSIONS: Increased workload and sleep disturbances increased the risk of injury, suggesting employers should address these factors to mitigate occupational injuries.<br><br>© 2019 Wiley Periodicals, Inc.<p /> <p>Language: en</p>",
