[Some occupational determinants of work disability].
Occupational determinants play a significant role in the studies of the causes of work disability. The duration of employment is that particular variable, frequently analysed, which reflects indirectly the effect of work conditions on the worker's health state and also on his her disease-related work disability. Therefore, the aim of this work was to show the difference in sick absenteeism between various occupational groups, depending on the duration of employment. The empirical material embraced data on work disability, among workers employed in the automative industry plant during the years 1989-94. Out of 8,599 persons covered with the study, 77% left the job, including 7% of those who left the job because of health problems. An analysis of the impact of occupational determinants on the sick absenteeism was carried out on the basis of the absenteeism rate adjusted by age, sex and occupational activity in groups of the production, auxilliary and administrative workers, as well as in occupational groups exposed to possibly similar harmful factors. The duration of worker's employment in the plant showed a positive influence on sick absenteeism, since together with extended period of employment the decrease in the rate of general sick absenteeism was observed. However, in a number of disease categories an increase in absenteeism together with extended duration of employment, and a high level of absenteeism among workers involved directly in the production, were noted. This proves an adverse effect of work conditions on work disability among workers. The effect of harmful factors present at workposts is also confirmed by the increasing sick absenteeism together with the prolonged duration of employment in various occupational groups. In the group of welders the highest level of sick absenteeism was observed among persons with duration of employment ranging from 11 to 20 years (rate: 10.52), and it was related to diseases of the respiratory (3.10) and circulatory (2.09) systems. In this group the increase in absenteeism together with prolonged duration of employment was related to diseases of the genitourinary system (about fourfold), musculoskeletal system (about threefold) and nervous system and sense organs (about 20%). It may be concluded that in selected high risk occupational groups, the duration of employment may reflect the effect of work conditions on workers' sick absenteeism, and the analysis of work disability caused by individual diseases provides an image of health effects due to hazards to which those groups are exposed.
