【 摘 要 】

Aims: the present study aims to evaluate the prevalence of cardiometabolic changes according to the hypertri-glyceridemic waist (HW) phenotype in Brazilian adults. Methods: it is a population based transversal study with 976 adults (n = 533 women) 20-59 years old. Phenotype was defined by triglycerides concentration (TGL) 150 mg/dl and waist circumference (WC) >= 80 cm in females and 90 cm in males. All the analyses were adjusted according to the study design and pondered by gender, age and schooling. A descriptive analysis was performed through averages and ratios; their respective confidence intervals were herein presented (CI 95%). The prevalence of cardiometabolic changes due to the presence of HW and to gender was calculated and compared by means of Pearson's chi-square test. Statistic significance level was 0.05. The probability of coronary event risk was estimated in 10 years and calculated from Framinghan score, using Kernel density graph. Results: no difference in phenotype prevalence between genders was observed. Higher averages in all the cardiometabolic risk factors analyzed and higher probability of evolving to a cardiovascular event in 10 years were observed in individuals with the HW phenotype. Lower HDL values were only verified in this group. Conclusion: the HW phenotype is an important cardiovascular risk sign and allows the premature identification of individuals with higher risk, so that its use in clinical practice must be encouraged, mainly because it is a simple low cost asset.
