Background This study investigated the relationship between weekly working hours and the occurrence of cerebro‐cardiovascular diseases using a case‐crossover study design. Methods We investigated average working hours during the 7 days before the onset of illness (hazard period) and average weekly working hours between 8 days and 3 months before the onset of cerebro‐cardiovascular diseases (control period) for 1,042 cases from the workers’ compensation database for 2009. Results Among all subjects, the odds ratio by conditional logistic regression for the risk of cerebro‐cardiovascular diseases with a 10 hr increase in average weekly working hours was 1.45 (95% confidence interval [CI]: 1.22–1.72), a significant association. Conclusions An increase in average weekly working hours may trigger the onset of cerebro‐cardiovascular disease. Am. J. Ind. Med. 60:753–761, 2017. © 2017. Wiley Periodicals, Inc.
