Weight programs usually focus on decreasing weight, even though abdominal fat distribution is more associated with diabetic/heart disease risks. Magnetic resonance imaging (MRI) is ideal for quantification of visceral fat depot; but, it is limited by expense and accessibility. Stereovision imaging was evaluated as a tool to promote management of abdominal adiposity in 60 men. Waist/hip circumferences, regional/total body volumes, fat mass, and central obesity depth (COD) [via stereovision imaging] were measured after a 4‐hr fast. Abdominal muscle and visceral/subcutaneous fat volumes were determined at the umbilicus as scanned by MRI. Greater central obesity depths were observed for overweight and obese subjects, as compared to healthy weights (p < 0.05). Visceral fat volume tertiles within same BMI categories and mean differences of COD were assessed, with Bonferroni corrections for post‐hoc analyses. For those with healthy weights, COD varied significantly between low and high, as well as middle and high, visceral fat tertiles (p < 0.05). This validates the ability of COD to differentiate between high/low risk individuals, even within same BMI categories. Similar trends were observed for overweight. Thus, COD measured via stereovision imaging is a strong predictor to evaluate central obesity, which can assist programs targeting abdominal adiposity. NIH 3R21DK081206‐02S1
