title: Psychological distress and dyslipidemia in chinese police officers: a 4-year follow-up study in Tianjin, China.
abstract: OBJECTIVE
  This study aimed at investigating whether psychological distress in police officers was associated with dyslipidemia.
  
  
  METHODS
  A survey was conducted to examine the psychological distress among 5867 police officers in Tianjin, China, from 2007 to 2011. Psychological distress was measured using the Symptom Check List-90-Revised. Cox proportional hazard regression was used to calculate the hazard ratios (HR) of the incidence of dyslipidemia predicted by psychological distress.
  
  
  RESULTS
  Among the 3300 participants without dyslipidemia at baseline (2567 with dyslipidemia), 60.5% (n = 1829) developed incident dyslipidemia 2.61 years (median) later. The adjusted HR was 1.15 (95% confidence interval, 1.05 to 1.26) after the adjustment of police classifications and other variables. The adjusted HR for police officers in charge of traffic control was 1.30 (95% confidence interval, 1.09 to 1.56).
  
  
  CONCLUSIONS
  Further investigations for associations of psychological factors with dyslipidemia and cardiovascular diseases are needed.
