  1. All models were adjusted for age in years, race/ethnicity, calcium supplement intake, smoking status, alcohol drinking, milk consumption, and at least 15 min sun exposure a day, plus postmenopausal in females
  2. Note: BMI = Body mass index; Fat mass = whole body fat mass; % Fat = percent of body fat
  3. Regular exercise: “no regular exercise” as the reference group; b = regression parameter estimates
  4. * < 0.05. ** < 0.01 *** < 0.001
