Mortality studies of dockyard workers (longshoremen) in italy

A polycentric mortality study was performed in five Italian harbours: Savona, Marina di Carrara, Livorno, Civitavecchia, and Ravenna. The cohort included active and retired workers (longshoremen), who had been employed between 1960 and 1981. Causes of death were ascertained from death certificates; expected numbers of deaths were generated from age, sex, calendar year, and cause-specific national mortality rates. A low overall mortality was found, which is in agreement with procedures of health selection, typical of physically demanding jobs; an excess of lung cancer was, however, found in four out of five harbours.
