Abstract 4189: Gender Difference in Inflammatory Markers: What is the Contribution of Visceral Adiposity?

TL;DRAbstract

Several studies have reported a gender difference in inflammatory markers associated with obesity. Indeed, whereas C-reactive protein (CRP) concentrations have been found to be higher in pre-menopausal women compared to men, interleukin (IL)-6 and tumor necrosis factor (TNF)-α levels have been found to be lower in women than in men because of the inhibitory effect of estrogens on the expression of inflammatory genes. Since body fat distribution is very different between men and pre-menopausal women, the contribution of visceral adipose tissue (VAT) to the gender difference in inflammatory markers is a question of clinical relevance. To examine this issue, plasma CRP, IL-6 and TNF-α levels were measured in a sample of 195 healthy men (age: 41.7±14.9 years) and 139 healthy women (age: 36.6±11.2 years). Pre-menopausal women were characterized by lower plasma TNF-α levels (1.57±0.59 pg/mL vs.1.85±0.99 pg/mL, p=0.001) and higher CRP concentrations (1.91±1.77 mg/L vs. 1.65±1.78 mg/L, p=0.04)
