β coefficients and 95% CI represent median difference in LPA, MPA, VPA, MVPA (min/day) and SB (hours/day) compared with participants with no diabetes as the reference. Significant results (p<0.05) are marked with*.
*Model 1: Multivariable regression model adjusted for age and sex.
†Model 2: Multivariable regression model adjusted for age, sex, and BMI.
‡Model 3: Multivariable regression model adjusted for age, sex, BMI, comorbidities, stress, mental well-being, and chronic pain.
BMI, body mass index; LPA, light physical activity; MPA, moderate physical activity; MVPA, moderate to vigorous physical activity; SB, sedentary behavior; VPA, vigorous physical activity.
