title: Risk factors for incidence of rotator cuff syndrome in a large working population.
abstract: OBJECTIVE
  The aim of this study was to assess the effects of personal and work-related factors on the         incidence of rotator cuff syndrome (RCS) in a large working population.
  
  
  METHODS
  A total of 3710 French workers were         included in a cross-sectional study in 2002-2005. All completed a self-administered questionnaire about personal         factors and work exposure. Using a standardized physical examination, occupational physicians established a diagnosis         of RCS. Between 2007-2010, 1611 workers were re-examined. Associations between RCS and risk factors at baseline         were analyzed by logistic regression.
  
  
  RESULTS
  A total of 839 men and 617 women without RCS at baseline were eligible         for analysis. RCS was diagnosed in 51 men (6.1%) and 45 women (7.3%). The risk of RCS increased with age for both         genders [odds ratio (OR) 4.7 (95% confidence interval [95% CI] 2.2-10.0) for men aged 45-49 years and 5.4         (95% CI 2.3-13.2) for women aged 50-59 years; reference <40 years]. For men, the work-related risk         factors were repeated posture with the arms above the shoulder level combined with high perceived physical exertion [OR         3.3 (95% CI 1.3-8.4)] and low coworker support [OR 2.0 (95% CI 1.1-3.9)]. For women, working with         colleagues in temporary employment [OR 2.2 (95% CI 1.2-4.2)] and repeated arm abduction (60-90°) [OR         2.6 (95% CI 1.4-5.0)] were associated with RCS.
  
  
  CONCLUSIONS
  Age was the strongest predictor for incident cases         of RCS, and arm abduction was the major work-related risk factor for both genders. Lack of social support was a         predictor for RCS among men.
