title: [Cardiovascular risk factors among males in 1989 and 2011-12 in a southern Chilean city].
abstract: BACKGROUND
  A successful cardiovascular prevention program should induce a reduction of risk factors along time.
  
  
  OBJECTIVE
  To assess changes in cardiovascular risk factors among males aged between 35 and 65 years living in Southern Chile.
  
  
  METHODS
  The results of two cross sectional household surveys, with a probability sampling stratified by socioeconomic status, were analyzed. Two hundred males were evaluated in 1989 and 800 in 2011-12, paired by age for selection.
  
  
  RESULTS
  In the second survey, a mean weight increase of 4.5 kg was recorded. Body mass index increased from 27.1 to 28.6 kg/m(2) (p < 0.01), especially in men younger than 45 years old. No changes in smoking prevalence were observed. The prevalence of hypertension and hypertensive patients in treatment increased from 32.7 to 38.1% and from 17 to 33%, respectively. The number of treated hypertensive patients with a well-controlled blood pressure did not change significantly. In 1989 and 2011-12, mean total cholesterol values were 192 and 201 mg/dl respectively (p < 0.01). The figures for mean non-HDL cholesterol were 152 and 160 mg/dl (p = 0.03). The frequency of people with total cholesterol over 240 mg/dl or using statins increased from 15 to 25% (p < 0.01). The estimated 10 years risk of myocardial infarction and coronary death using Framingham tables was 9,0 in both periods (p = 0.95).
  
  
  CONCLUSIONS
  In a 22 years period an increase in the prevalence of obesity and elevated total cholesterol was observed. There was a higher proportion of individuals treated for hypertension and dyslipidemia, but without reduction in the estimated cardiovascular risk.
