title: [A matched case-control study on the risk factors of metabolic syndrome among policemen].
abstract: OBJECTIVE
  To investigate the life style, genetic and occupational risk factors of metabolic syndrome (MS) among policemen.
  
  
  METHODS
  1:4 matched case-control study was used, based on physical examination data of Tianjin Policemen in 2010, 708 patients with MS were randomly selected as cases, which were matched with 2832 healthy controls on the basis of sex and age (+/- 1 year). An epidemiological investigations on the past exposure status of several possible risk factors was conducted, and the data were analyzed with conditional logistic regression.
  
  
  RESULTS
  Fifteen factors related to exposure were identified for MS through univariate conditional logistic regression analysis. Multivariate conditional logistic regression analysis suggested that, seven factors, such as family history of hypertension (OR = 2.406, 95% CI: 1.946-2.975), family history of diabetes (OR = 1.301, 95% CI: 1.043-1.623), smoking (OR = 1.357, 95%CI: 1.010-1.823), snoring (OR = 1.268, 95% CI: 1.043-1.543), work intensity (OR = 4.603, 95% CI: 3.767-5.623), occupational stressful events (OR = 1.524, 95% CI: 1.209-1.922), security policemen (OR = 1.453, 95% CI: 1.127-1.872) and criminal investigation policemen (OR = 2.792, 95% CI: 2.168-3.596), could significantly increase the risk of disease development, but dairy products (OR = 0.782, 95% CI: 0.619-0.989) was a protect factor for MS. The results from population attributable risk factors analysis showed that the control of smoking, snoring, work intensity, occupational stressful events can decreased the risk of MS to 16.26%, 11.71%, 56.87% and 8.97%, respectively.
  
  
  CONCLUSIONS
  Metabolic syndrome has became a significant public health problem among policemen, it's necessary to take measures on life style, occupational risk factors for reducing the incidence of MS, and improving the health level among policemen.
