BMI: body mass index, WC: waist circumference, SBP: systolic blood pressure, DBP: diastolic blood pressure, HOMA-IR: homeostasis model assessment of insulin resistance, HDL-C: high density lipoprotein cholesterol, LDL-C: low density lipoprotein cholesterol, hs-CRP: high sensitivity C-reactive protein, IGF-1: insulin-like growth factor-1, and Carotid IMT: carotid intima media thickness. To converte lipid concentration from mg/dl into mmol/L; for total, HDL, and LDL cholesterol divide mg/dL by 38.6 and for triglycerides divide mg/dL by 88.57. Data are expressed as mean ± standard deviation; *P is significant if <0.05.
