Repeated case-control studies as a method of surveillance for asthma in occupations.
Our aim was to establish whether the case-control design may be applied in surveillance for occupational asthma.
In a region with intensive manufacturing industries, we carried out one case-control study from 1974 to 1978 and another from 1989 to 1993 ; 325 and 387 pairs of cases of asthma and of age-and sex-matched control subjects, respectively, were selected.
Current risks were found to be higher than past estimates for painters, farmers, millers/bakers, textile, wood/furniture, and chemical workers.
High risks for asthma have recently appeared in leather, polyurethane plastics, hospital and food industry workers, welders, and shoemakers.
It is concluted that the case-control approach may be used to describe variations in asthma risk by occupational categories and time.
A method to measure the efficiency of the diagnostic process for occupational asthma is also proposed.
