The objective of this study was to obtain fundamental data for the development of health educational program about prevention of occupation- related disease and promotion of health among dental technicians. The subjects were 339 dental technicians who were working in 159 dental laboratories, Taegu area. A survey with a questionnaire was conducted from June, 15, 1998 to Augnst, 15. 1998. 30 examiners were trained for the questionnaires surveys. The questionnaires composed of general characteristics, occupational characteristics, health life, working condition(such as stress, wearing protector, working posture), health knowledge. Subjects were also asked about experience on health complaints during last 1 year. The obtained results were as follows
(1) The distribution of subjects were male(88.5"O), married(53.7,)). The most characteristics were twenties(46Y)b0, below than 4 years of work duration(34.5"o), other technicians(53.:V,(,), all works of working pari(17A"~;), above 10 hours in a day of working time((i8.20). The 4 health life, 7 hours of sleep on the average were 35.7"0, who regularly exercise were 25.3 who drink 1-2 times per week were 42.894;, 3-4 times were 28.9`1)0. (2) Health complaints by general characteristics, occupational characteristics, health life were significantly different as follows : Eye symptoms by gender(p<0.01), duration of work(p<0.05), position (p<0.(15), working part(p<0.05), working time(p<0.05), hours of sleep(p<0.05) ; Ear symptoms. by hours of sleep(p<0.05), exercise(p<0.05); General symptoms by gender(p<0.05), position (1)<0.05), smoking(p<0.05);Dermal symptoms by age(p<0.05), marital status (p<0.05), position (p<0.01 );Mu sculoskeletal symptoms by gender(p<0.05), age(p<0.01), duration of work(p<0.05), position (p<0.05), workingtime(p<0.05), exercise(p<0.05), smoking(p<0.05);Digestive symptoms by gender(p<0.01), age(p<0.05), duration of work(p<0.05), position (p<0.01), alcohol consumption (p<0.05);Respirator7 symptoms by working part(p<0.01), exercise(p<0.05), smoking (p<0.05). (3) In the correlation of health complaints and stress, working posture, wearing protector, the stress was factor which had positive correlation to all ´symptoms (p<0.01), the working posture was factor which had positive correlation to general psymptoms(p<0.05), dermal symptoms (p<0.05), musculoskeletal symptoms (p<0.01). (4) In the correlation of health complaints and health knowledge were as follows : The knowledge level of occupation-related disease was factor which had positive correlation to eye symptoms (p<0.05), ear symptoms(p<0.01), general symptoms (p<0.05), musculoskeletal symptoms (P<0.015), digestive symptoms (p<0.05), respiratory symptoms (P<0.05). The knowledge level of work hazard was factor which had positive correlation to all symptoms (p<0.001) - (5) In the regression analysis, The factors which affected health complaints were as follows : Eye symptoms were gender( Q =0.4542), position(,8 =0.3409), hours of sleep (,8 =0.1733), alcohol consumption( R =0.2824), stress(,3=0.2871), knowledge level of work hazard( Q =0.2262), explained them by 13.4%. Ear symptoms were stress(,8 =0.4447), knowledge level of occupation related disease(,6 =0.1492), explained them by 11.3%. General symptoms were gender( Q =0.2685), position(Q =0.3196), stress (.8 =0.3570), explained them by
19.6%. Dermal symptoms were position(,8=0.1437), stress(.8=0.2734), explained them by 15.6%. Musculoskeletal symptoms were position(,8=0.2411), stress(.8=0.1335) explained them by 23.3%. Digestive symptoms were gender (,8=0.3402), marital status(,8=0.2073), position( R =0.2461), stress( Q =0.2850), explained them by 17.7%. Respiratory symptoms were smoking (,8 =0.1851), stress(,8 =0.4542), knowledge level of work hazard(,8=0.1780), explained them by 15.0%.
