Unlike subcutaneous and visceral adipose tissue depots which are low in AN, MAT levels are paradoxically elevated and are inversely associated with BMD.
We divided our population into 5 groups with different phenotypes characterizing the severity of the disease and/or the severity of bone involvement: 1 - Normal BMD and body mass index (BMI): recovery from AN; 2 - Osteopenia (-2<Z-score<-1) and BMI>17kg/m<sup>2</sup>; 3 - Osteopenia and BMI≤17kg/m<sup>2</sup>; 4 - Osteoporosis (Z-score≤-2) and BMI>17kg/m<sup>2</sup>; 5 - Osteoporosis and BMI≤17kg/m<sup>2</sup>.
