‡, the highest AUC for every CMRF in each sex and age group. a, significant when compared with BMI; b, significant when compared with WHtR; c, significant when compared with ABSI; d, significant when compared with ABSI-adolescents. BMI, body mass index; WHtR, waist-to-height ratio; ABSI, a body shape index; ABSI-adolescents, ABSI for adolescents; BRI, body roundness index; CMRF, cardio-metabolic risk factor. Clustered CMRFs: in the four items of hypertension, dyslipidemia, IFG and abdominal obesity, meet three or more.
