  1. BMI: body mass index, WC: waist circumference. BMI classification according to the classification of the Asia-Pacific perspective redefining obesity in adult Asian were: underweight < 18.5 kg/m2, normal 18.5-22.9 kg/m2; overweight at risk 23-24.9 kg/m2; obese I 25-29.9 kg/m2; obese II ≥ 30 kg/m2 [17]. Abdominal obesity was based on waist circumference if ≥ 90 cm in male or ≥ 80 cm in female [17]. All p-values were calculated using the Chi-square test.
