Circulating adiponectin levels were higher in women compared to men (30.72 ± 6.32 μg/mL versus 11.26 ± 3.49 μg/mL, P = 0.016), but no other differences were observed with regard to age, BMI, fasting insulin and glucose plasma levels, insulin resistance as assessed by HOMA-IR index, or plasma resistin, TNF-α and IL-6 proteins between men and women (Table 1). This evidence concerns the gene TNF and Insulin resistance.
