To determine whether adiposity assessed by dual-energy X-ray absorptiometry (DXA) compared to simple anthropometric assessments, are more predictive of abdominal aortic calcification (AAC), a risk factor for atherosclerosis. A cross-sectional study of 312 participants (60.3 % female) aged 70.6 ± 5.6 years was conducted in 2010-2011. AAC was assessed by radiography. Adiposity was estimated for whole body, trunk, android, gynoid and visceral regions using DXA in addition to body mass index (BMI), waist circumference (WC) and waist to hip ratio (WHR). WHR [tertile 1 as reference, OR (95 % CI) for tertile 3: 3.62 (1.35-9.72)] and android to gynoid fat ratio [tertile 3: 2.87 (1.03-8.01)] were ind..View full abstract
