MedicalResearch.com Interview with: Albert Roh MD Radiology Resident Maricopa Integrated Health System MedicalResearch.com: What is the background for this study? Dr. Roh: Obesity is well documented to be associated with many medical conditions.  Currently, obesity is defined as body mass index (BMI) over 30 kg/m^2.  Although simple to calculate and relatively accurate, BMI has its limitations.  BMI does not factor in the subject’s body type or fat distribution pattern.  For example, a muscular subject and a fatty subject may both have BMI of 30 and be considered obese, although the muscular subject would not be predisposed to the comorbidities associated with obesity.  Similarly, two subjects may have the same BMI but have different fat distribution patterns: “apple” with fat distributed primarily on the chest/abdomen and “pear” with fat distributed on the hips.  The “apple” fat distribution correlates better with the comorbidities associated with obesity.
