INTRODUCTION: Obese people are at higher cardiovascular risk than people with normal body weight. The objective of this study was to establish the relationship between obesity, body fat distribution and cardiovascular risk factors. METHODS: Body mass index (BMI), waist-hip ratio (WHR) systolic (SBP) and diastolic blood pressure (DBP), plasma cholesterol, triglycerides and glucose levels were determined in a population of 499 overweight and obese patients (432F/67M; age 39±12.9y). RESULTS: High prevalence of abnormal glucose tolerance or diabetes (21.8%), hypercholesterolenemia (49.1%), hypertri glyceridemia (21.3%) and hypertension (43.8%) were found in this population. The prevalence of hypertension increased from 23% in patients with BMI 25-29.9 kg/m2 to 67.1% (p 40kg/m2 and also from 35.7% in patients with WHR between 0.73 and 0.88 to 66.6% in those with WHR >0.97 (p 40kg/m2, (p<0.05). CONCLUSION: Our data reinforce the association between obesity and high cardiovascular risk. In addition, our findings suggested a role for body fat distribution in the development of hypertension in obese patients.
