Disability Pensions Due to Musculo-Skeletal Disorders among Men in Heavy Occupations A Case-Control Study

The relative risk of disability pension due to musculo-skeletal disorders has been studied with regard to occupation and work load. The study population comprised men born 1915 to 1934, living in Stockholm county. 1307 men who received a disability pension during 1979, 1980, 1981 and 1984 due to disorders from the low back, neck/shoulder, hip, and knee were compared with 298 randomly selected men concerning occupation and occupational work load. Disability pensions were more common both in men with medium and high physical work load compared to men with low physical work load. Construction workers and metal workers had a high relative risks of receiving disability pensions because of disorders in all four body regions, and men in many other occupations had disorders in two or three regions. In office workers the risk of disability pension because of musculo-skeletal disorders was low.
