||The triad of shift work, occupational noise, and physical workload and the risk of coronary heart disease
||June 2006, Vol.63, No.6, p.378-386. Illus. 41 ref.
||This study was undertaken to evaluate the short and long term effects of shift work, noise and physical workload on the risk of coronary heart disease (CHD) and to estimate the joint effects of these factors. It was carried out in the form of a 13-year follow-up of 1804 middle-aged industrially employed men. The CHD end points were obtained from official Finnish registers. The Finnish job-exposure matrix FINJEM provided information on occupational exposures. Relative risks of CHD for the exposures were estimated using Cox's proportional hazard models adjusting for classical risk factors of CHD. Findings are discussed. Shift work and continuous noise entailed an excess risk for CHD in the shortest follow up with only a few retired workers but a decreasing risk during the longer follow up. For physical workload and impulse noise the trend was opposite: the CHD risk was increasing with increasing follow up time despite increasing numbers of retired workers. Possible reasons for these findings are discussed.
