title: Effects of an assessment of needs for medical and social services on long-term mortality: a randomized controlled study.
abstract: BACKGROUND
  The aim of this study was to investigate the long-term effects of one general health screening on mortality.
  
  
  METHODS
  After stratification and randomization of a population of 450,000 inhabitants, two groups were formed, an intervention group of 3064 people and a control group of 29,122 people. From the National Cause of Death Register, data were collected as regards death and causes of deaths for 1970-1990.
  
  
  RESULTS
  Multivariate analysis was used to correct for known confounders. We then found no differences between the groups regarding deaths from all causes, cardiovascular diseases, cancer or accidents and poisoning.
  
  
  CONCLUSIONS
  One general health screening seems to have little, if any value in preventing fatal diseases.
