[Health surveillance in ridden work environments by means of the MM040/IAQ Questionnaire].

Complaints and symptoms related to the indoor environment experienced by 3380 workers were collected from 26 workplaces by using the Italian modified version of the Swedish questionnaire MM-040 and the Finnish IAQ-Indoor Air Quality questionnaire. Complaints related to environmental factors, and air related symptoms, were common in indoor workers. Women reported work related symptoms more often than men, the difference being significant. The Indoor Air Quality questionnaire is a suitable tool for the occupational health physician in investigating indoor air problems. In the Italian version six general symptoms were added to the symptom scale, in order to make the questionnaire feasible for analysis of general health, during medical surveillance at work.
