Frequent musculoskeletal symptoms and reduced health-related quality of life among industrial workers.

The high percentage of musculoskeletal symptoms (MSS) found in studies of general populations and various occupational groups underlines the need to distinguish between severely and mildly affected individuals. To investigate associations between MSS and quality of life, we examined the frequency of MSS on a five-point scale, health-related quality of life (SF-36) and sickness absence among 5654 workers in the aluminium industry. High frequencies of MSS from all body parts were related to lower scores on the SF-36 and increased sickness absence. This relationship was strongest for MSS from the lower back. Workers who reported low back MSS 'very often' had a mean role--physical score equivalent to that of the 15th percentile of the general population. These results show that workers who reported MSS often or very often were severely affected, and this scale can therefore be used to distinguish individuals at high risk for reduced health-related quality of life and sickness absence.

Prevalence of musculoskeletal symptoms among aluminium workers.

The aim of this study was to determine the prevalence of musculoskeletal symptoms (MSS) in workers in the aluminium industry, and to test the relationship with work by using the duration of employment as a measure of exposure. A total of 5654 workers (92%) answered a questionnaire. Operators, who were more exposed to physically demanding work, showed a greater incidence of MSS than did office workers. Among operators, the duration of employment was significantly correlated with MSS in nine out of ten areas of the body, when adjusted by multiple regression analyses for age, gender, height, weight, smoking and physical activity. Among office workers this relationship was weaker and was significant only for neck and lower back areas. The higher prevalence of MSS among operators and the association between their duration of employment and MSS suggests that a higher risk of MSS is related to the working environment.
