CHAMPS = Community healthy activities model program for seniors. ^†IQR = interquartile range. ^‡Caloric expenditure scores include (1) all activities defined as the total kilocalories expended during activities of any intensity during a typical week and (2) moderate-intensity defined as the total kilocalories expended during activities of at least moderate intensity (MET value ≥ 3.0) during a typical week. ^§Frequency scores include (3) all activities defined as the number of activities of any intensity during a typical week and (4) moderate intensity defined as the number of activities of at least moderate intensity (MET value ≥ 3.0) during a typical week.
