Sagittal abdominal diameter: comparison with waist circumference and its prediction of metabolic syndrome

Background  

For an “in the field” estimate of visceral adiposity, simple, inexpensive, non-invasive and highly repetitive methods are needed. The anthropometric measurement most commonly used as an indicator for visceral fat deposits is waist circumference (W). Nevertheless, there are some doubts with regard to the anatomic landmark points where the evaluation needs to be carried out. Sagittal abdominal diameter (SAD) is another anthropometric measurement that has been proposed for the estimation of visceral fat.
