Obesity was employed as a surrogate for the waist circumference criterion given the limitations of chart review data. Criterion estimates are based on a restricted sample of those with the requisite laboratory or vital sign data. The extended sample metabolic syndrome estimate utilized patients with at least three of the following measures available: body mass index, blood pressure, fasting triglycerides, fasting HDL or fasting glucose. The restricted sample utilized only those patients for whom all of these measures were available.
Obesity rate 95% C.I. (40.2–55.5%) significantly exceeds NHANES 2005–2006 general population estimate, accounting for sample gender proportions.
Hypertriglyceridemia rate 95% C.I. (36.9–59.3%) significantly exceeds and low HDL rate (18.6–31.2%) is significantly lower than NHANES 1999–2000 general population estimates. Metabolic syndrome 95% C.I. from extended sample rate (28.1–44.7%) and restricted sample (40.8–65.4%) also exceed general population estimates.
