  1. Note:* P < 0.05.
  2. 1Individual attendance = individual-level intervention attendance rate.
  3. 2Community partnership = average community partnership score.
  4. 3. Models were adjusted by covariates including gender, years of education, annual income, age, body mass index (BMI), sarcopenia status, and chronic diseases.
  5. 4. Adjusted p-values (Adj. p) and adjusted confidential intervals (Adj. CI) account for multiple comparisons using the Šidák correction method.
