Development and Cross-Validation of Anthropometric Predictive Equations to Estimate Total Body Fat Percentage in Adult Women in Sri Lanka

Table 4

Equations developed to estimate TBFP of middle-aged women in Group A (n = 175).

Step	Basis of equation	Equation			R^2	SEE
1	Circumferences	TBFP1	32.484 + 0.464 (HC) − 28.385 (height)	0.81	0.66	3.12
2	SFTs	TBFP2	44.623 + 0.154 (age) + 0.207 (weight) − 24.118 (height) + 0.163 (ThSFT) + 0.092 (SISFT) + 0.141 (BSFT)	0.85	0.71	2.84
3	Circumferences and SFTs	TBFP3	23.286 + 0.259 (HC) − 15.449 (height) + 0.172 (ThSFT) + 0.123 (age) + 0.074 (SISFT) − 0.27 (CaC) + 0.137 (BSFT) + 0.112 (ThC)	0.87	0.76	2.65
4	Highly significant circumferences and SFTs	TBFP4	23.657 + 0.297 (HC) − 19.261 (height) + 0.175 (ThSFT) + 0.113 (age) + 0.065 (SISFT)	0.86	0.73	2.76

TBFP = total body fat percentage; SFT = skinfold thickness; HC = hip circumference; CaC = calf circumference; ThC = thigh circumference; BSFT = biceps skinfold thickness; ThSFT = thigh skinfold thickness; SISFT = suprailiac skinfold thickness. r = correlation coefficient, R² = determination coefficient, and SEE = standard error of estimate. Weight in kg, height in m, circumference in cm, and SFT in mm. Correlations were significant at <0.001 level.
