Objectives: To study health and re-employment in a five-year follow-up of a
community sample of long-term unemployed people. Methods: A random sample
registered for more than 12 weeks at the labour offices in Grenland, Norway
, were given medical check-ups in 1988 and 1990, and a postal questionnaire
in 1993. Results: Only 37% were employed five years after the first spell
of long-term unemployment. Recovery after re-employment was demonstrated, i
ndicating that unemployment causes poor mental health. Health-related selec
tion to continuous unemployment was only found for medical diagnoses. The u
nemployed who might be selected to continuous unemployment because of poor
health at the two-year follow-up seemed to deteriorate most. Conclusion: Th
e high morbidity of mental health problems among unemployed people is mostl
y explained by the causal hypothesis. This is a challenge to preventive med
icine. Sick unemployed people should be given special attention.
