APPENDIX INFORMATION: RTH FORMULA

To calculate the ratio of waist circumference to hip circumference, simply divide the waist circumference by the hip circumference . The ratio should not exceed 0.8 for women and 1 for men . For example, for the woman if her waist circumference is 70 cm and her hip circumference is 90 cm, the ratio will be 0.77 which is a correct value. For information, the waist circumference is measured with a measuring tape, passing by the navel (that is to say by the widest part of the trunk normally).
