Table 3.
Obesity classification using different anthropometric measures. Obesity was defined as BMI (by height or arm span) > 30 kg/m2, abdominal girth > 102 cm in males or > 88 cm in females, or by DXA trunk fat % ≥ 30% in males or ≥ 35% in females. Overweight was defined as BMI > 25 kg/m2 or abdominal girth > 94 cm in males or > 80 cm in females. No accepted overweight standard value for DXA trunk fat percent is available. Statistical significance relative to conventional BMI (by height) was calculated using McNemar test.
