To evaluate mortality
patterns among participants in a community-based screening program for asbestos
We calculated standardized mortality
ratios (SMRs) and stratified results by exposure group (three occupational exposure groups, household contacts and residents without occupational asbestos
exposure) and by radiographic abnormality presence.
(15.8%; 1,429/8,043) was statistically lower than expected. Asbestosis
was statistically elevated in all exposure groups. Lung cancer was moderately associated with vermiculite miner/miller employment. Mesothelioma
was elevated in that same exposure group and among residents. Systemic autoimmune disease mortality
was also elevated. Radiographic parenchymal abnormalities were associated with lung cancer mortality
In addition to asbestos
in occupational exposure groups, this initial follow-up of this cohort also shows elevated mortality
for some asbestos
-related causes in non-occupational exposure groups.
