Abstract
Background: Occupational exposure to asbestos is responsible for 80% at fea st of all mesothelioma in developed countries. In France there are importan t regional differences in the rate of mesothelioma compensated as occupatio nal diseases, without knowing if these differences could be explained by a real difference of risk The objective here is to quantify these regional di fferences in relation with the differences of level of risk. Methods: The analysis compares, for each of the 16 regions of the national social security system, mortality for both genders and among men by pleural cancer (ICD 263) in the general population and mesothelioma compensated as occupational diseases during the 1986-1993 period. We computed for each re gion the number of expected compensated mesothelioma under the hypothesis w here the regional distributions of compensated mesothelioma and mesotheliom a deaths are the same; as well as the percentage of compensated mesotheliom a compared to the deaths, and the variation from the national mean under tw o hypotheses, high and low; and the probability that a mesothelioma is comp ensated as an occupational disease taking as a reference the "best" region. Results: The compensation rate differed significantly among regions (p < 0. 05) and for men, the rate between observed and expected numbers of compensa ted mesothelioma varied from 0.15 (region of Montpellier) to 2.29 (region o f Nantes), a ratio over 15. For all of France, the compensation rate was 25 % under the best hypothesis. The region of Nantes compensated 61.5% of the male mesothelioma as occupational diseases, while the region of Montpellier and Clermont-Ferrand only around 5%. The probability for a mesothelioma to be compensated, compared to the region of Nantes, was 2.5 times less in na tional average, and about 10 times less in Montpellier and Clermont-Ferrand regions. Conclusion: In spite of limits linked to the imprecision of the available d ata, important regional differences in term of compensation of mesothelioma as occupational diseases clearly exist. Indications lead to think that the ir origin lies essentially in differences between physicians when consideri ng the occupational etiology of mesothelioma, but differences within the sy stem of compensation of occupational diseases can not be excluded An improv ement of the national statistical system concerning occupational diseases i s highly recommendable.
