Data are shown as odds ratios (95%CIs) that Pre-frailty and Frailty compared to the Robust in each model using multinomial logistic regression. LPA, Light Physical Activity; MVPA, Moderate-to-Vigorous Physical Activity. Model 1, adjusted for age, sex, education, living alone, drink and smoke status, polypharmacy, MoCA score, PSQI score, IADL, and wear time. |
Model 2, a, additional adjusted total MVPA time |
b, additional adjusted total sedentary time |
c, additional adjusted bouted MVPA and sporadic MVPA. |
