Abstract

Objective: Although obesity is associated with metabolic changes, not all obese patients are characterized by the metabolic syndrome (MS). The goal of this study was to determine the prevalence of the MS, its characteristics, and the associated demographic factors in a large cohort of severely obese patients presenting for potential bariatric surgery. Methods: A total of 256 obese patients (68.7% female, 41.9 +/- 11.6 years, BMI 49 +/- 9.1 kg/m(2)) were evaluated using the harmonized criteria of the MS. Results: In this cohort, the prevalence of MS was 78.1% with no gender difference. The prevalence did not correlate with BMI, body weight, or waist circumference;however, the presence of MS and numbers of MS criteria met correlated with age. The prevalence of individual criteria varied considerably (central obesity [100%], hypertension [86.7%], elevated glucose (58.6%), low HDL-cholesterol [50%], and hypertriglyceridemia [43.7%]). On average, 3.4 +/- 1.1 criteria were met, 3.5% fulfilled only one criterion (central obesity), and 16.4% met all 5 criteria. After adjusting for age and gender, hypertriglyceridemia and hypertension were more common in diabetic than in non-diabetic patients. Similarly, low HDL and elevated glucose were more common in hypertriglyceridemic individuals. Conclusion: In severely obese patients, the prevalence of the MS and the number of criteria met was high. However, over 20% of severely obese individuals have no MS and thus may be at lower risk for cardiovascular complications of obesity. It is currently unclear whether treatment strategies with respect to obesity should differ between severely obese individuals with and without the MS.
