Abbreviations: BMI body mass index, WC waist circumference, WHR waist-hip ratio, WHtR waist-height ratio, TRSKF triceps skinfold thickness
BMI was classified into underweight/normal weight group vs overweight/obese group; WC, WHR, WHtR, and TRSKF were dichotomized by the median values
P: *P < 0.05
P values were calculated by Chi-square test
