  3. aEstimates correspond to differences in means of the sPPF associated with a 1-SD difference in the device-based activity pattern metric (SDs same as reported in Table 2). Models included adjustment for awake wear time, age, gender, race/ethnicity, education, body mass index, osteoarthritis, depressive symptoms, Charlson comorbidity index, and MVPA, and incorporated weighting to account for selection into the analytic sample. Bolded results indicate a significant interaction (p < 0.05) by age, gender, or quartiles of MVPA, respectively
