IntroductIon. Cardiovascular diseases (CVD) are the main cause of death in Brazil. objectIve. To evaluate the frequency of CVD risk factors in a population attending a community-based health education intervention. Methods. A retrospective analysis of 428 completed forms with clinical and demographic information of volunteers attending a public health event, held in May 2006. The chi-square test was used for comparisons between proportions and the Student t test for comparisons between groups. Associations between hypertension, diabetes mellitus (DM) and clinical variables were analyzed using a multivariate logistic regression model. Significance level was set at p < 0.05. results. Mean age was 57±14 years, and women represented 58% of the total population. Most frequent cardiovascular risk factors included hypertension (39.5%), DM (15.4%) and dyslipidemia (25.8%); however, 8.4, 17.5 and 33.1% of the respondents, respectively, were unaware of these risk factors. Family history of CVD was reported by 41% of the respondents, and only 67% reported having any information about DM or dyslipidemia. Among obese individuals (BMI ≥ 30 kg/m 2 , 27.3% of the population), systolic blood pressure (133±16 mmHg), diastolic blood pressure (84±11.5 mmHg) and casual glucose (124±52.5 mg/dL) were higher than those among non-obese individuals (p < 0.05). There was an association between obesity and dyslipidemia (p = 0.04). Age and BMI were independently associated with presence of hypertension and DM. conclusIon. The high prevalence of modifiable risk factors in this study population suggests a need for public health interventions to promote education and primary prevention programs targeting, mainly, the elderly and overweight individuals.
