Association of general and abdominal obesity with age, endocrine and metabolic factors in Asian men

Figures & data

Table 1. Distribution of men with general obesity (PBF ≥ 25%) and with abdominal obesity (PAbdF ≥ 25%).

	PAbdF < 25%, n = 457	PAbdF ≥ 25%, n = 25
PBF < 25%, n = 451	427	24
PBF ≥ 25%, n = 31	30	1

Table 2. Sensitivity and 1-Specificity for W, W/H and W/Ht when the cut-off value for abdominal obesity was set at a percent abdominal fat (PAbdF) of 25%.

	Cut-off value when Sensitivity = 100%	1-Specificity
W (cm)	86.5	0.638
W/H	0.887	0.534
W/Ht	0.511	0.655
