Equation of Huston Presley et al for Fat Mass in a Pregnant Woman at 30 Weeks of Gestation

 

Patient selection: pregnant woman to 30 weeks gestation (predominantly white)

 

Parameters:

(1) body weight in kilograms

(2) triceps skinfold thickness in mm

(3) subscapular skinfold thickness in mm

(4) suprailiac skinfold thickness in mm

 

fat mass in kilograms =

= (0.33529 * (body weight)) + (0.65664 * (triceps skinfold)) – (0.4373 * (subscapular skinfold)) + (0.43461 (suprailiac skinfold)) – 13.0538

 

Limitations:

• The skinfold measurements have to be taken very carefully, else methodologic variation can influence the results.
