Abstract

The aim of this study was to identify forms of work organization in a French region and to study associations with the occurrence of symptomatic and clinically diagnosed shoulder disorders in workers. Workers were randomly included in this cross-sectional study from 2002 to 2005. Sixteen organizational variables were assessed by a self-administered questionnaire: i.e. shift work, job rotation, repetitiveness of tasks, paced work/automatic rate, work pace dependent on quantified targets, permanent controls or surveillance, colleagues' work and customer demand, and eight variables measuring decision latitude. Five forms of work organization were identified using hierarchical cluster analysis (HCA) of variables and HCA of workers: low decision latitude with pace constraints, medium decision latitude with pace constraints, low decision latitude with low pace constraints, high decision latitude with pace constraints and high decision latitude with low pace constraints. There were significant associations between forms of work organization and symptomatic and clinically-diagnosed shoulder disorders.

4. Discussion

This study identified five forms of work organization in a sample of French workers: low decision latitude with pace constraints (Group 1), medium decision latitude with pace constraints (Group 2), low decision latitude with low pace constraints (Group 3), high decision latitude with pace constraints (Group 4) and high decision latitude with low pace constraints (Group 5). Associations between forms of work organization and shoulder pain of any duration during the preceding 12 months and shoulder pain during the preceding seven days were revealed for men after adjustment for age. More men workers in Group 1 had shoulder pain than workers in the other work organization groups (except for workers in Group 2 with shoulder pain during the preceding seven days). More women workers in Group 1 had symptomatic and clinicallydiagnosed shoulder disorders compared to other workers, except for workers in Group 4. Indeed, more workers in this form of work organization had shoulder pain during the preceding seven days and clinically-diagnosed shoulder disorders than workers in Group 1 (not statistically significant). This confirmed our hypothesis; workers in forms of work organization with high organizational constraints (Group 1 and Group 4) had more shoulder disorders than other workers, especially in women.
