Abstract: | Purpose The aim of the study was to examine the organizational and psychosocial risk factors for carpal tunnel syndrome (CTS) in workers exposed to various levels of work-related constraints, with a special focus on factors related to the work organization. Methods From 3,710 workers, representative of a French region’s working population, trained occupational physicians diagnosed a total of 156 cases of CTS between 2002 and 2005. Diagnoses were established by standardized physical examination, while personal factors and work exposure were assessed by self-administered questionnaires. Statistical associations between CTS and personal and work-related factors were analyzed for each gender using logistic regression modeling. Results Among the factors related to work organization, working with temporary workers was associated with CTS for women (OR = 1.99, 95 % CI 1.23–3.25), but not for men. Task rotation during the job (OR = 2.45 95 % CI 1.41–4.24) and work pace dependent on quantified targets (OR = 1.93 95 % CI 1.08–3.46) were associated with CTS only for men. The work-related psychosocial factors highlighted by the logistic modeling were high psychological demand for women (OR = 1.90, 95 % CI 1.17–3.09) and low skill discretion (OR = 1.77, 95 % CI 1.01–3.11) for men. Conclusion This study has identified some psychosocial factors and factors related to work organization associated with clinically diagnosed and symptom-only cases of CTS as well as personal and biomechanical factors. However, due to the cross-sectional design of the study, no causal conclusion could be drawn and longitudinal studies are necessary to confirm these results. |
