Data shows mean ± SD or n (%). IADL, Instrumental Activity of Daily Living; MoCA, Montreal Cognitive Assessment; PSQI, Pittsburgh Sleep Quality Index; LPA, Light Physical Activity; MVPA, Moderate to Vigorous Physical Activity. Bouted MVPA was defined as ≥ 10 consecutive min, with an allowance for up to 2 min out of 10 to drop below the MVPA intensity threshold. Sporadic MVPA was defined as any MVPA accumulated in < 10 min. |
