[Hazards to workers' health caused by work-related psychosocial factors--a challenge to occupational health services].

Health hazards which occur at work are related with exposure to physico-chemical and psychosocial factors. Little concern has been given so far to the latter group of factors by occupational health services in their diagnostic and preventive activities. That resulted from a specific character of psycho-social stimuli and their direct effect on workers' health disorders. A large multitude and variety of psycho-social hazards, a growing exposure to these hazards and health effects induced by them together with economic consequences call for much more attention to be paid to these factors. It will not be an easy task and that is why the authors speak about a challenge to occupational health services.
