The purpose of this study was to find out the associations between urinary catecholamines and cortisols and subjective complaints of fatigue in shiftworkers. We conducted a field survey of 113 male shiftwork subjects who were working at a manufacturing company in South Korea from late October to late November in 1999. The shiftwork system in the company was the backward rapidly rotating 4-crew 3-shift(morning session starts at 7:30 AM). we examined (1) self-report questionnaire (demographic characteristics, past medical history and working hours), (2) subjective complaints of fatigue in 3 categories of questionnaire (I, II, III) and (3) levels of norepinephrine(NE), epinephrine(EP), dopamin(DP) and creatinine in urine collected for 2 hours during each shift. The average age of workers was 29 years (range 25∼44) and the mean period of shiftwork was 1,857 days(range 163∼3,484 days). we compared subjective complaints of fatigue with hormone levels in urine in the two groups, one group with less 5 years mean shiftwork period and the other group with more than or equal to 5 years mean shiftwork period with age controlled. In workers with short shiftwork period(less than 5 years mean shiftwork period), significant association was found (1) between subjective complaints of fatigue Iand EP, and DP in morning session, (2) between subjective complaints of fatigue II, III and NE, EP and DP in afternoon session, and (3)between subjective complaints of fatigue I, II, III and EP only in night session. In workers with long shiftwork period(more than or equal to 5 years mean shiftwork period), significant association was found between subjective complaints of fatigue II and NE and EP in morning session only. Therefore we concluded that there was a possibility of healthy shiftworker effect. These results suggested that there was difference in urinary catecholamines and cortisols level between workers with short shiftwork period and workers with long shiftwork period. Further research concerned with shiftwork period and urinary catecholamines is warranted.
