Notes: Data presented as mean ± standard deviation unless stated otherwise. The criteria of ADL score: 100 (independence), 75–95 (mild dependence), 50–70 (moderate dependence), 25–45 (heavy dependence), and 0–20 (total dependence). IPAQ2: categorical score – three levels of physical activity are proposed: 1) low (no activity is reported OR, some activity is reported but not enough to meet Categories 2 or 3). 2) Moderate (either of the following three criteria, ≥3 or more days of vigorous activity of at least 20 minutes per day OR, ≥5 or more days of moderate-intensity activity and/or walking of at least 30 minutes per day, or ≥5 or more days of any combination of walking, moderate-intensity or vigorous-intensity activities achieving a minimum of at least 600 MET-min/wk). 3) High (any one of the following two criteria, vigorous-intensity activity on at least 3 days and accumulating at least 3 days and accumulating at least 1,500 MET-min/wk OR ≥7 or more days of any combination of walking, moderate- or vigorous-intensity activities accumulating at least 3,000 MET-min/wk).
