title: [A matched nested case-control study on the risk factors of metabolic syndrome among male criminal policemen].
abstract: OBJECTIVE
  To explore the risk factors and their differences of metabolic syndrome (MS) on male criminal police, thereby provide the scientific basis to make prevention and control strategies about the metabolic syndrome for the criminal police career.
  
  
  METHODS
  Based on physical examination data of criminal police in 2010, 439 patients with MS (CDS) were randomly selected as cases. And as the 1:2 matched nested case-control study, 878 health controls were employed, which were matched with on the basis of sex and age (±1 year). An face-to-face epidemiological investigations on the past exposure status of several possible risk factors was conducted, such as the family history of hypertension and other social economic status, as well as body height and weight, waist circumference, blood pressure, serum lipid and plasma sugar. and the data were analyzed with logistic regression.
  
  
  RESULTS
  1317 cases were surveyed, through single factor logistic regression analysis found that 12 factors are related to exposure. Multivariate logistic regression analysis suggested that six factors, such as stress events (OR = 1.989, 95%CI: 1.467∼2.696), snoring (OR = 1.672, 95%CI: 1.218∼2.294), sweets (OR = 0.562, 95%CI: 0.412∼0.766), meat and products (OR = 1.494, 95%CI: 1.065∼2.094), siting after dinner for more than 3 h (OR = 1.399, 95%CI: 1.023∼1.915).
  
  
  CONCLUSIONS
  MS has become a important public health problems among criminal police. For their professional special, a series of bad habits , unhealthy life style and psychological problems became important risk factors of MS on criminal police. Targeted prevention and control measures should be taken to reduce the incidence of MS.
