BackgroundThis study investigated the relationship between weekly working hours and the occurrence of cerebro-cardiovascular diseases using a case-crossover study design.
MethodsWe 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.
ResultsAmong all subjects, the odds ratio by conditional logistic regression for the risk of cerebro-cardiovascular diseases with a 10hr increase in average weekly working hours was 1.45 (95% confidence interval [CI]: 1.22-1.72), a significant association.
ConclusionsAn increase in average weekly working hours may trigger the onset of cerebro-cardiovascular disease. Am. J. Ind. Med. 60:753-761, 2017.
