Abstract

BACKGROUND: The objective was to examine the relationship between seasonal variations in sleep quantity and work-related injuries on Saskatchewan farms. METHODS: A cross-sectional analysis of data from the Saskatchewan Farm Injury Cohort Study was conducted. Analyses were restricted to workers, aged ≥16 years. The primary outcome was work-related injury in the last year. Logistic regression models were used to identify associations between sleep quantity and farm injury. RESULTS: After controlling for confounding variables peak production season sleep was not associated with increased odds of injury. However, those obtaining ≤5 hr sleep per night during non-peak production seasons had increased odds of injury (OR 2.42, 95% CI 1.04-5.59) compared with those sleeping ≥7 hr per night. CONCLUSIONS: We identified that restricted sleep durations, in certain seasons, placed farmers, and farm workers at risk of injury. Agricultural injury intervention programs need to consider the role of seasonal-related variations in sleep on farm injury. Am. J. Ind. Med. © 2011 Wiley Periodicals, Inc.
