(Note: Levene’s Test showed the variances were statistically equal between groups (p < 0.05) for each variable, one-way ANOVA was adopted to examine the difference between groups; Abbreviation: BMI = body mass index; WHR = waist-hip-ratio; TC = total cholesterol; TG = triglyceride; HDL-C = high density lipoprotein cholesterol; LDL-C = low density lipoprotein cholesterol; FPG = fasting plasma glucose; OGTT 2 h PG = OGTT 2 hour plasma glucose; SBP = systolic blood pressure; DBP = diastolic blood pressure).
