Abbreviations: BMI body mass index, WC waist circumference, SBP systolic blood pressure, DBP diastolic blood pressure, TC total cholesterol, TG triglycerides, HDL-C high-density lipoprotein cholesterol, LDL-C low-density lipoprotein cholesterol, FBG Fasting blood glucose, HOMA-IR homeostatic model assessment of insulin resistance. Data are expressed as mean ± SD. #Skewed distributions were logarithmically transformed for one-way ANOVA. Values in the same row with different superscript letters are significantly different, with P < 0.05, that is, difference groups with the same superscript letter in the same row are no statistical significant.
