Different working and living conditions and their associations with persistent neck/shoulder and/or low back disorders.

Abstract

To investigate whether different combinations of working and living conditions are associated with the risk for persistent neck/shoulder and/or low back disorders. The underlying purpose of this contextual approach was to identify target groups for primary/secondary prevention. In a baseline study, 11 groups with different working and living conditions were identified by cluster analysis. In this study, these 11 groups were followed up by a postal questionnaire 5 years after baseline (response rate 82%, n = 1095). Five of the groups--the onerous human services job, the free agent, the family burden, the mentally stretched and the physically strained groups--had an increased risk for persistent disorders (OR 2.38-2.70). Four of these groups had rather sex-specific working and living conditions. The results support the hypothesis that different combinations of working and living conditions may increase the risk for persistent neck/shoulder and/or low back disorders to different degrees. Sex-specific working and living conditions increased the risk for women as well as for men, irrespective of whether the conditions were specific to women or men.
