OBJECTIVES: A longitudinal study was conducted to determine the predictability of personal and occupational factors with respect to the incidence of @entity3140 in occupations requiring repetitive work. METHODS: A sample of 598 workers in five activity sectors completed a self-administered questionnaire; the workers were examined by an occupational health physician in 1993-1994 and 3 years later. Three disorders were considered, @entity923 ( @entity923 ), @entity2633 and wrist @entity924 . RESULTS: The results of this longitudinal study indicated that the following three sets of risk factors independently affect the incidence of @entity3140 : (i) biomechanical constraints, (ii) psychosocial factors, and (iii) personal factors. The combination of risk factors differed between @entity923 , @entity2633 , and wrist @entity924 . The presence of psychosomatic problems was a strong predictor of wrist @entity924 . Social support at work was also associated with the incidence of wrist @entity924 . The presence of @entity308 and other @entity3140 predicted the first occurrence of @entity2633 . Age was associated only with @entity2633 . The results were consistent with those concerning the role of forceful movements of the elbow for @entity2633 and confirmed the role of forceful movements for @entity923 . CONCLUSIONS: This study considered different sets of risk factors simultaneously with a longitudinal approach, in a population with a high level of occupational exposure. The results indicate that three sets of risk factors independently affect the incidence of @entity3140 . In addition to biomechanical constraints, psychosocial and personal factors play a role.
