title: [An epidemiological study on carotid atherosclerosis among veterans in Beijing].
abstract: OBJECTIVE
  To investigate the prevalence and risk factors of carotid atherosclerosis (CAS) among veterans in Beijing.
  
  
  METHODS
  820 individuals, aged 60 or above, were randomly selected out from 8202 individuals, 21 military cadre retirement centers in Beijing. Each individual answered a questionnaire and received Doppler ultrasonic examination for an observation of the Internal-Media Thickness and structure of the carotid. A logistic regression analysis was also made to identify possible risk factors and their powers on the prevalence of CAS.
  
  
  RESULTS
  The prevalence of carotid atherosclerosis by ultrasonic examinations among the veterans in Beijing was 44.0%, of which males taked 53.8% and females taked 33.5%. The prevalence rised with the increase of age. Among them, the prevalence ratio of CAS for ages of 60-69, 70-79, and 80 or above were 30.4%, 51.8%, 65.27%, respectively. Logistic regression was done to provide the following results: CAS risk factors include the age, sex, obesity, smoking, hypertention and diabetes mellitus.
  
  
  CONCLUSIONS
  The prevalence of CAS among the veterans in Beijing rises with the increase of age. CAS risk factors include age, sex, obesity, smoking, hypertention and diabetes mellitus.
