title: [Prevalence of several cardiovascular risk factors in a population in the municipality of Viseu].
abstract: OBJECTIVE
  To assess the prevalence of the main changeable cardiovascular risk factors (hypertension, hypercholesterolemia and smoking) in the population of the Viseu municipality.
  
  
  METHODS
  The population was obtained through a publicity campaign in local radios and on lighted placards in the town of Viseu. We chose a set of volunteers above 20 years of age, who answered a questionnaire about smoking habits, academic qualifications, profession and residence. After the inquiry, the total cholesterol and blood pressure were determined. We considered hypertension (HBP) values > or = 140/90 mmHg and hypercholesterolemia > 200 mg/dl.
  
  
  RESULTS
  1852 persons were inquired (3.2% of the population of the Viseu municipality) 1173 of which were females. According to the age groups, we verified that the ages between 50 and 69 years represented 47.9% of the total amount of volunteers. In what concerns smoking habits, we found a prevalence of 9.1% (15.9% in males and 5.2% in females). In the study of the prevalence of HBP we found a value of 38.5%, higher in males (42.8%) than in females (35.9%). The prevalence of hypercholesterolemia found was 34.9% (no significant differences between the sexes).
  
  
  CONCLUSIONS
  In comparison with other studies carried out in the Portuguese population, a low prevalence of smoking habits, high hypertension and similar hypercholesterolemia were found.
