Measurements The height, BW, waist circumference (WC), and blood pressure (BP) of all patients were measured. The body mass index (BMI) was calculated as the BW in kilograms divided by the square of the height in meters. After overnight fasting, blood was collected for analyzing the fasting plasma glucose (FPG), TG, and high-density lipoprotein cholesterol (HDL-C) levels. Under manufacture's guide, fasting TG, FPG, and HDL-C levels were measured using an automated system (Roche Cobas C501).
