“…Many fathers had a history of exposure to dust before their marriage. For example, the means of the average age at the beginning of exposure among many of the examined families (1,4,6,8,9,14,17,25,27,29, 32, 33) were below 21 (table 1). The "apparently" lower prevalence of silicosis among workers with fathers with no history of exposure to silica-bearing dust than those from fathers with a history of exposure (less than 10 years) (table 6) might be because some of the workers in the first group who develop respiratory ailments leave the work and change their jobs, while fewer workers in the latter group would do so because of their family ties with their occupation.…”

A previous investigation has shown that family susceptibility and occupational and family histories have a decisive role in the development of byssinosis among workers exposed to flax dust. Results of investigation of silicosis in 814 male workers exposed to silica-bearing dust showed that family susceptibility has an important role in the development of silicosis among examined workers, and workers whose fathers had an occupational history of exposure to silica-bearing dust were more resistant to the development of the disease than those with non-exposed fathers. The degree of consanguinity of parents and individuals' blood groups, also, have a role. Workers with cousin parents were relatively highly susceptible to the development of silicosis as well as workers with blood groups "O" or "AB." It has been concluded that the investigated factors might have a role in the development of other occupational diseases and further investigations are indicated.
