a, MetS were defined based on World Health Organization (WHO) (Laaksonen et al., 2002), National Cholesterol Education Program Adults Treatment Panel III (NCEP ATP III) (Grundy et al., 2005) and International Diabetes Federation (IDF) criteria (Alberti et al, 2006) criteria; b, Chi-square using IDF criteria; c, Chi-square using NCEP ATP III criteria; d, Chi-square using modified WHO criteria. WC, waist circumference; BMI, body mass index; FBG, fasting blood glucose; HDL, high density lipoprotein; TG, triglyceride; BP, blood pressure.
