In the health metrics world, BMI, or Body Mass Index, has traditionally been the preferred measure for evaluating obesity. However, there is a new metric emerging called Body Roundness Index, or BRI, which some believe offers a more precise way to assess obesity and its health implications.
BMI is a common measurement that uses a weight/height ratio to determine obesity. However, one of its limitations is that it can misidentify someone as obese because it does not distinguish between muscle or fat in the thighs and hips from the more dangerous visceral fat around the abdominal organs.
Dr. Zeena Al-Rufaie, a pediatrician and obesity specialist, explains that BMI may not provide a complete picture of body composition, whereas the Body Roundness Index can offer a more accurate indication of body shape and fat distribution, which may be better correlated with metabolic risks and mortality as it increases. The BRI focuses on waist circumference and height, without factoring in weight, which allows for a more accurate assessment of visceral fat that is associated with conditions like high blood pressure, heart disease, diabetes, and certain cancers.
While BRI is still relatively new and not widely used in clinical practice, especially in pediatrics, it may provide additional insights when used alongside BMI. Dr. Al-Rufaie suggests that both indices should be part of a comprehensive health assessment rather than relied upon individually as diagnostic tools. If you are unsure about the BMI results provided by your healthcare provider, it may be helpful to inquire about your Body Roundness Index or waist circumference to gain a more comprehensive understanding of your overall health status.
