A Thesis submitted to The University of Arizona College of Medicine - Phoenix in partial fulfillment of the requirements for the Degree of Doctor of Medicine. / Importance: This study proposed a new radiographic measure of obesity that is a better
predictive indicator of obesity‐related risk: Fat/Bone Ratio. Primary Objective: Does the
Fat/Bone Ratio correlate with obesity. Secondary Objective: Does the Fat/Bone Ratio correlate
more closely with the comorbidities of obesity as compared to BMI. Design: Retrospective
review of 2703 upright posterior‐anterior (PA) and lateral chest radiographs obtained from June
2013 through May 2014. The soft tissue height overlying the acromioclavicular joint was
calculated and divided by the mid‐clavicle width to determine the Fat/Bone Ratio.
Comorbidities of obesity were determined through chart review. Setting: Adult community
emergency department. Participants: All adults (age greater than 18). Main Outcomes and
Measures: BMI, Fat/Bone Ratio, comorbidities: hypertension, obstructive sleep apnea,
osteoarthritis, hyperlipidemia, atherosclerosis, coronary artery disease, cerebrovascular
accident, and myocardial infarction. Results: Fat‐to‐Bone ratio and BMI were both significantly
associated with hypertension, diabetes, hyperlipidemia, obstructive sleep apnea, and
osteoarthritis (P < .05). However, only Fat/Bone Ratio is associated with atherosclerosis (p =
0.02), coronary artery disease (p = 0.001), myocardial infarction (p = 0.002), and peripheral
vascular disease (p = 0.01); BMI is not associated with these comorbidities (p = 0.90, 0.42, 0.25, and 0.50, respectively). Conclusions and Relevance: Findings suggest that Fat/Bone Ratio is an improved measure of obesity as compared to BMI.
