摘要：Screening study was focused on the assessment of fatigue in workers exposes to organic dust (jute and wood) and chemicals. Material end methods: The group exposed to jute dust consisted in 110 workers (98 females) in the following workplaces: squashing, carding, laminating, spinning, twisting, starching, rolling, where there are: fibers and dust of jute, noise, adverse microclimate (at starching). The group exposed at wood dust consisted in 57 workers (33females), in workplaces of manual and mechanical brush sections, where there are fibers and dust of wood (species: oak, beech tree, fir-tree, lime-tree, poplar, nut-tree, cherry-tree, ash -tree). The group exposed to chemicals (organic solvents and dyes) consisted in 56 workers (53 females) in the following workplaces: finishing and dying sections. Control group consisted in 92 (35 females) office workers. Results and discussion: mean values for age was 39.6±9 years in the investigated groups; mean total work length was 20±8 years. Multidimensional checklist individual strength (CIS20R) questionnaire with 20 items self reported questionnaire that referred to fatigue experienced during the previous two weeks has been administered. It consisted of four dimensions: the subjective feeling of fatigue, and motivation reduction, activity diminution and concentration reduction. By adding the four dimensions a CIS total score can be calculated. Higher scores indicate a higher degree of fatigue, more concentration problems, reduced motivation and less activity. Statistical differences were noted in exposed groups vs. controls (p <0.001). Total scores (%) were: 76.53 for workers exposed to jute dust, 75.38 for workers exposed to wood dust, 83.22 for workers exposed to chemicals, 44.1 in controls. Test sensibility : 72.59% (in workers exposed to jutedust), 57.95% (in workers exposed to wooddust), 59.34% (in workers exposed to chemicals). In the absence of gold standard for fatigue, CIS were able to discriminate adequately between fatigued and non-fatigued employees in occupational exposure to organic dust (jute and wood), chemicals and office workers. Conclusions: Differences of subscales of fatigue (dimensions of fatigability) were noted by categories of exposure (levels and noxious agents).
