TABLE 4.

Final equations for predicting 5C %BF in healthy adults.

Full model
 %BFNew = 6.083 + (0.143 × SSnew) − (12.058 × sex) − (0.150 × age) − (0.233 × BMI) + (0.256 × WC) + (0.162 × sex × age)
Reduced models
 Male
  %BFNew = − 5.975 + (0.143 × SSnew) − (0.312 × Age) − (0.233 × BMI) + (0.256 × WC)
 Female
  %BFNew = 6.083 + (0.143 × SSnew) − (0.150 × Age) − (0.233 × BMI) + (0.256 × WC)

SSnew, sum of thigh, midaxillary, and triceps skinfolds, in mm; Sex, coded as 0 = female, 1 = male; Age, in years; BMI, body mass index in kg·m−2; WC, waist circumference in cm. Note: sex-specific equations were derived by substituting the “sex” variable for either 0 (female) or 1 (male) in the full model and then combining like terms.
