title: [Analysis on essential hypertension risk factors of the high incidence in traffic officers].
abstract: OBJECTIVE
  To study on essential hypertension risk factors of the high incidence in traffic officers. In order to provide evidence for prevention and control of hypertension.
  
  
  METHODS
  139 out of all male marshals who had been serving more than 3 years in a certain railway were studied as occupational crowds of high prevalence rate in essential hypertension (Prevalence rate was 41.7%); 306 male train crew who had similar conditions in seniority and age with the marshals from two sections of this railway were studied by cluster random sampling as occupational crowds of low prevalence rate (Prevalence rate was 21.9%). They were surveyed the common risk factors for hypertension, occupational factors, occupational stress and type A behavior by the health questionnaire designed uniformly. Their lipids and blood glucose were detected. The cause for hypertension were compared in the differences and characteristics.
  
  
  RESULTS
  (1) The risk factors and exposure of essential hypertension in the high incidence in the marshals were more higher than those in the low incidence in crew, and the exposure rate of the risk factors grew faster in the marshals than in the crew with working age. (2) By the same exposure rate of the risk factors in the marshal were more higher risk than those of the crew. (3) The risk factors and the danger lever were different in these two groups. The occupational stress, BMI, drinking habits and working age were the main risky factors, their ROR followed by 3.65, 3.33, 2.56 and 2.64, in the marshals. Hyperlipemia, elevated triglyceride, elevated cholesterol, ages and family history of hypertension were the main risk factors, their RR followed by 4.59, 3.38, 3.33, 2.96 and 2.25, in the crew.
  
  
  CONCLUSIONS
  The essential hypertension among people worked on the train mainly result from the change and increase of professional social psychic factors and behavial factors as well as the increased sensitivity and responsibility of blood vessel formed in a long-time high exposure to the risk factors.
