(B) Waist Circumference (cm) with knots ranging from 60 to 140 by 10 unit intervals and the reference point of 90 cm. (C) Waist to hip ratio (WHR): using knots ranging from 0.7 to 1.4 with 0.1 unit intervals and the reference point of 0.9. (D) Waist to height ratio (WHT): using knots ranging from 0.4 to 0.9 with 0.1 unit intervals and the reference point of 0.6.
