Sagittal abdominal diameter (sad) in comparison with other anthropometric methods and its correlation with insulin resistance in pre-diabetes
Background: The likelihood of future progression to diabetes mellitus can be assessed using various indicators of insulin resistance. Waist circumference, body mass index (BMI) and waist hip ratio are routinely employed in estimating obesity, which in turn contributes to insulin resistance. Sagittal abdominal diameter (SAD), is measured with the patient in supine position, causing the subcutaneous fat to fall down towards either side, and hence leaving the harder visceral fat to be measured by SAD. Waist circumference, however, measures both subcutaneous and visceral fat.
