title: Metabolic syndrome in patients with high blood pressure in Cuiabá-Mato Grosso State: prevalence and associated factors.
abstract: 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.
  
  
  METHODS
  This was a cross-sectional study (May to November 2007) in a sample of 120 patients with high blood pressure (aged > or = 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 > or = 140 mmHg and/or diastolic blood pressure > or = 90 mmHg; 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 > or = 25 kg/m(2), insulin resistance and family history of high blood pressure.
  
  
  CONCLUSIONS
  A high prevalence of MS was observed among patients with high blood pressure living in Cuiabá, with a significant association with BMI > or = 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.
