A retrospective study by the Minnesota Department of Health of noncancer mortality in highway maintenance workers (HMW) in Minnesota was presented. This is the first systematic study of HMW who have been exposed to a wide range of potential workplace hazards. Subjects were classified as either urban or rural workers. Variables in the study were age at death, year of death, age and year subject started working, years worked and time from start of work until death. Causes of death were divided into twenty four categories. The causes of death of HMW were compared with statistics for the general population. Of the 4849 white male workers who had worked one or more years during the period of 1945 to 1984, there were 1530 deaths, 9 percent less than expected. There were fewer deaths than expected due to cancer, heart disease and cerebrovascular disease, the three main causes of death in the general population. Elevations in mortality were found for some causes such as diabetes and renal disease but these appear to be unrelated to highway maintenance work. Mortality rates were elevated for transportation injuries, particularly among the short term urban workers and were related to inexperience and more hazardous work performed. The authors suggest that HMW are exposed to various workplace hazards and further comprehensive studies are needed.
