Defining expected mortality in occupational studies

by Vinni K, Hakama M

The mortality in a reference population for specific occupations was evaluated by means of occupational studies of different designs. The data originated from a random sample of 19,862 persons from among the total Finnish population. The age standardized mortality for those who had at any time belonged to the active work force in Finland was estimated to be 10 % less than the average mortality for the total population. The difference was 20 % if the currently active work force was compared with the total population. The standardized mortality ratio was 70 % for those who had stayed for less than 10 years within the same occupational category and 80 % for those with more than 10 years` work within the same occupational category. The expected mortality varied up to 50 % depending on the broad occupational category and on the occupational history when compared with the total mortality in Finland.
