title: Exposure to nonpermanent employment and health: analysis of the associations with 12 health indicators.
abstract: OBJECTIVE
  To clarify the associations of nonpermanent employment with poor health in longitudinal setting with different health outcomes.
  
  
  METHODS
  A population cohort (n = 1071) was surveyed at the age of 30 and then again at the age of 42. They were classified according to exposure to nonpermanent employment. The outcomes included indicators of mental and somatic health and health behavior.
  
  
  RESULTS
  When adjusted for baseline level of the outcome under study, the odds ratio of the heavily exposed was 1.90 (1.25 to 2.88) for nervous symptoms, 1.77 (1.03 to 2.05) for psychological distress, and 1.52 (1.03 to 2.25) for suboptimal mood. Among the lightly exposed, the odds ratio for psychological distress was 1.94 (1.10 to 2.10).
  
  
  CONCLUSIONS
  Psychological distress is particularly sensitive to exposure to nonpermanent employment. The effects on somatic health or health behavior should be studied only with carefully specified hypotheses.
