Trunk:Peripheral fat ratio = DXA trunk fat mass/[DXA arm fat mass + DXA leg fat mass].

All independent variables were entered in the multiple regression. Independent variables were from Exam 2 except that physical activity and energy values for Exam 1 and 2 were averaged to increase reliability. Adjusted R² = 29%.
