[The role of age at start of employment on the development of silicosis].

Multipart we examined the statistical connection of the age at job start and the development of silicosis by analytical epidemiological means. Examined on the basis of the professional duration no correlative connection was found in respect to the relation in question. The comparison of the two groups of dust exposed workers, which in their investigations have been shown to be "disposed" or "resistant", yielded no difference. In another study that investigated the function of cumulative dust doses the results varied so heavily, that the advantages and disadvantages of the different age groups at job start statistically mutually leveled off. Therefore, the age at job start may not be considered as an influencing factor of silicosis development.
