title: Risk factors for long-term absence due to psychiatric sickness: a register-based 5-year follow-up from the Oslo health study.
abstract: OBJECTIVE
  To identify individual and work-related predictors of long-term (>8 weeks) sickness absence with psychiatric diagnoses (LSP).
  
  
  METHODS
  Data from the Oslo Health Study (response rate 46%) were linked to public registers. A total of 8333 subjects were followed from 2001 through 2005. Cox regression was used to compute hazard ratios for LSP.
  
  
  RESULTS
  At least one LSP was present in 7.8% of women and 3.9% of men. Poor support from superior had an independent and moderate effect. Path and linear regression analyses indicated that the effect of support from superior was mediated through mental distress and not the other way around. Self-reported mental distress had a strong independent effect.
  
  
  CONCLUSIONS
  Women had a higher risk of LSP than men. Low education and poor support from superior and mental distress were found to be determinants of LSP.
