  1. Values are mean (95% CI)
  2. Model 1 adjusted for age and gender
  3. Model 2 additionally adjusted for delivery organization, baseline mobility, number of chronic conditions, education, and BMI (measured)
  4. * Significant difference between age groups at specified time point
  5. Significant differences between time points bolded
  6. Note: Physical activity as measured by the CHAMPS physical activity questionnaire; SPPB, short performance physical battery
