Functional score***−0.932−3.798−3.798
  • Fat mass and distribution was assessed with DXA performed with GE Lunar iDXA version 15. ALT, alanine aminotransferase; GGT, γ-glutamyl transferase; IGT, impaired glucose tolerance; NA, not available; NAFLD, nonalcoholic fatty liver disease; PCOS, polycystic ovary syndrome; T2DM, type 2 diabetes mellitus.

  • **Predicted body fat = (1.48 × BMI) − 7.

  • ¶Yes or no indicates the presence or absence of either condition.

  • §Yes or no indicates the presence or absence of this syndrome.

  • #Yes indicates NAFLD as confirmed by ultrasound and magnetic resonance spectroscopy.
