title: Occupation, morbidity, and hospital admission.
abstract: BACKGROUND
  The Occupational Hospitalization Register (OHR) is an ongoing register for research and surveillance established by the National Research Centre for the Working Environment in the 1980s. This review puts in perspective the contributions from the OHR to the understanding of relation between work and the burden of diseases in general and circulatory disease in particular.
  
  
  RESULTS
  This review covers selected topics in which studies based on OHR has contributed to the scientific knowledge during more than two decades. One PhD thesis and so far 49 OHR studies have contributed to the estimation of the excess fraction of several diseases attributable to work and to the identification of relative risks for occupational diseases like circulatory diseases, diseases of the nervous system, musculoskeletal disorders, pulmonary disease, infertility, and recently also mental disorders.
  
  
  CONCLUSIONS
  OHR is a cost-effective instrument for surveillance of health consequences of the working environment and social conditions as well as a valuable register for ad-hoc studies of the aetiology of occupational diseases.
