OBJECTIVES: @entity102 ( @entity102 ), which comprises primary/idiopathic @entity66 , and secondary sequels after @entity1150 are major health issues in Western countries. The present study was conducted to prove the hypothesis that the development of @entity102 might be triggered by exogenous, occupational risk factors. METHODS: We determined the prevalence and social relationship of @entity102 in a wide cross-section of hospital employees (n = 209; medical doctors and nurses, medical technician assistants, secretaries, scientific staff, cleaners and utility workers) without predocumented @entity102 . Prevalence, known endogenous risk factors for @entity102 and occupational and environmental risk factors (family history of @entity66 , history of @entity1150 , current oral contraceptive therapy, @entity28 , regular participation in sports or frequent use of saunas or sun-baths, and long periods of standing during work) were investigated. The restriction in quality of life due to symptoms of @entity102 was also evaluated. @entity102 was classified according to the @entity17622 criteria. RESULTS: @entity102 was present in a total of 70 employees (34%), predominantly in @entity1 . Standing at work was a predisposing factor. We found the highest prevalence of @entity102 in utility workers and cleaners and the lowest prevalence in medical technician assistants, secretaries and scientific staff. CONCLUSION: The study demonstrated that within a representative cross-section of hospital employees in a University hospital the prevalence of @entity102 was highest in @entity1 , especially in those working in a standing position or under conditions of high temperature and humidity. The results warrant regular evaluation of risk factors with subsequent primary prophylaxis of @entity102 .

High prevalence of chronic XXXX in hospital employees.
