RESUMO

OBJECTIVE - To determine the risk factors prevalence for coronary artery disease in the State of Rio Grande do Sul, Brazil and to identify their relation with the age bracket. METHODS - We carried out an observational, cross-sectional study of 1,066 adults older than 20 years in the Brazilian State of Rio Grande do Sul. We investigated the risk factors familial antecedents, systemic arterial hypertension, high levels of cholesterol and glycemia, overweight/obesity, smoking and sedentary lifestyle. A standardized questionnaire completed at the patients' dwellings by health agents were used; the data were stored in an EPI-INFO software database. The results were expressed with a 95 percent confidence interval. RESULTS - The sample composition was of 51.8 percent females. The risk factors prevalences were 1) sedentary lifestyle 71.3 percent; 2) familial antecedents 57.3 percent; 3) overweight/obesity (body mass index >25) 54.7 percent; 4) smokers 33.9 percent; 5) hypertension 31.6 percent (considering >140/90mmHg) and 14.4 percent (considering >160/95mmHg); 6) high glycemia (>126 mg/dL) 7 percent; 7) high cholesterol >240 mg/dL) 5.6 percent. CONCLUSION - The prevalence of the major risk factors for coronary artery disease in the Brazilian state of Rio Grande do Sul could be determined in a study that integrated public and private institutions
