Regression logistic models* analyzing the effect of AVF, adiponectin and FFA on insulin resistance prevalence

	Normal AVF		High AVF
	Normal ADIPO	Low ADIPO	Normal ADIPO	Low ADIPO	Interaction p
Women	1	3.7(2.1-6.6)	3.4(2.0-5.7)	7.6(4.2-13.8)	0.6
Men	1	1.9(1.0-3.6)	2.5(1.4-4.3)	4.1(2.6-7.2)	0.7
	Normal AVF		High AVF
	Normal FFA	High FFA	Normal FFA	High FFA
Women	1	2.2(1.1-4.1)	2.8(1.7-4.6)	4.5(2.3-8.8)	0.5
Men	1	0.8(0.4-1.8)	2.1(1.3-3.4)	2.3(1.2-4.2)	0.6

*Age, body mass index, high sensitive C-reactive protein, physical activity, total caloric intake, and FFA or adiponectin levels were included as co-variables (similar results were obtained after including triglycerides, HDL-C and glucose plasma levels in the model). AVF = Abdominal visceral fat; FFA = Free fatty acids; ADIPO = Adiponectin; HDL-C = High density lipoprotein cholesterol. Cut-off values are defined in material method section.
