Notes. BMI= Body Mass Index, WC= Waist Circumference, SA= Subcutaneous adipose tissue, VAT= Visceral adipose tissue. Statistically significant results are p ≤ 0.05 and are presented in bold.

^aModels for WC, SAT, and VAT were analyzed separately where each model was adjusted for age, height, physical activity index (PAI), current smoking and menopausal status (in women alone)
