Abstract |
This survey was conducted to investigate the relationship between sleep duration and cardiovascular events among male workers, accounting for occupational factors that might confound the true relationship. A total of 2282 male employees of a metalworking factory in Japan aged 35-54 years were followed for 14 years. The risk of cardiovascular events was compared among 4 groups stratified based on sleep duration at baseline. Cardiovascular events included stroke, coronary events and sudden cardiac death. The hazard ratios for events were calculated using a Cox proportional hazards model, with the 7-7.9-hour group serving as a reference. The model was adjusted for potential confounders including traditional cardiovascular risk factors and working characteristics. During 14 years of follow-up, 64 cardiovascular events were recorded including 30 strokes, 27 coronary events and 7 sudden cardiac deaths. After adjustment for possible confounders, the hazard ratios for cardiovascular and coronary events in the <6-hour group were 3.49 and 4.95, respectively. There was no significant increment in the risk of stroke for any sleep duration groups. |
