Background: Metabolic Syndrome (MS) is a cluster of predisposing factors for cardiovascular diseases and diabetes
mellitus, whose epidemiological characteristics are poorly known at regional and national levels.
Objective: To estimate the prevalence of MS and its associated factors in a sample of patients with high blood
pressure in the urban area of Cuiabá, Mato Grosso State.
Metods: This was a cross-sectional study (May to November 2007) in a sample of 120 patients with high blood pressure
(aged ≥ 20 years), paired by gender and selected by the systematic sampling of a source population of 567 patients with
high blood pressure in Cuiabá. All patients answered to home inquiries to provide sociodemographic and life habits
data. The following measurements were taken: blood pressure; body mass index (BMI); waist and hip circumferences;
plasma glucose, insulin, and lipid levels; homeostasis model assessment-estimated insulin resistance (HOMA); C-
reactive protein, uric acid and fibrinogen levels. High blood pressure criterion: average systolic blood pressure ≥
140mmHg and/or diastolic blood pressure ≥ 90mmHg; and Metabolic Syndrome diagnosis according to the I Brazilian
Directive for Metabolic Syndrome and the NCEP-ATP III criteria.
Results: 120 patients (60 women), with high blood pressure and an average age of 58.3 ± 12.6 years, were analyzed. We
found a MS prevalence of 70.8% (95%CI 61.8 to 78.8), predominantly among women (81.7% vs. 60.0%; p=0.009), with
no difference between adults (71.4%) and elderly patients (70.2%). The multiple regression analysis showed a positive
association between MS and BMI ≥ 25 kg/m 2 , insulin resistance and family history of high blood pressure.
Conclusion: A high prevalence of MS was observed among patients with high blood pressure living in Cuiabá, with a
significant association with BMI > 25 kg/m 2 , insulin resistance (HOMA index) and, especially, a family history of high blood
pressure. These results suggest the need for deeper studies on this subject.
