THE DETERMINATION OF HUMAN BODY SURFACE AREA ON THE BASIS OF BODY MASS, HEIGHT AND WAIST CIRCUMFERENCE VALUES

Objective - to increase the accuracy of calculating the body surface area (BSA) on the basis of increased number of anthropometric parameters registered. Material and methods. The known formulas for the determination of human BSA based on body mass and length, were analyzed. The data obtained from the study of 59 men and 59 women, were used for a correlation-regression analysis of the dependence of BSA, calculated by the Mosteller formula, on the value of the generalized parameter equal to the body mass divided by body length and multiplied by the waist circumference. Results. It was shown that the formulas for determining BSA using only body mass and length can not reflect its dependence on the individual features of the body shape. The formulas for determining BSA of men and women using the measured values of body mass, length and waist circumference are proposed. Conclusions. The values of BSA, calculated from the formulas proposed, coincide with those determined from known formulas using only mass and length, only with standard ratios of mass, height and waist circumference. When human body parameters deviate from the accepted criteria of the norm, the proposed formulas give BSA values adequately reflecting these deviations.
