The relationships between body fat percent and bone mineral density in girls at the ages of 12 to 18 years

Values are regression coefficient.

BMD: bone mineral density, METs · min: metabolic equivalent-minutes.

^*P < 0.05. ^**P < 0.01. ^†Adjusted for age, menarche status, height, weight, serum 25-OH vitamin D, physical activity (METs · min/wk), energy intake, and calcium intake using linear regression analysis with complex sampling design. ^‡Adjusted for age, menarche status, height, bone mass-free lean mass of whole body, serum 25-OH vitamin D, physical activity (METs · min/wk), energy intake, and calcium intake using linear regression analysis with complex sampling design.
