“…Physical activity level: The CHARLS questionnaire divides the physical activity of the elderly into three levels: high, moderate, and low intensities, including the number and duration of physical activity of different intensities per week [ 28 ]. More than 3 h of physical activity were recorded per day at different intensities to “180 minutes.” Only the physical activity of different intensity types were allowed and quantified at a maximum of 21 h per week to avoid misclassification of the samples into the high-intensity physical-activity group Based on the assigned metabolic equivalents (METs), different types of physical activity were observed at various intensity levels in the Summary of Physical Activity (8.0 for high-intensity physical activity, 4.0 for moderate-intensity physical activity, and 3.3 for low-intensity physical activity) [ 29 ]. One week of physical activity energy expenditure was obtained using the formula (1 week of physical activity energy expenditure = metabolic equivalent of physical activity corresponding to the type of intensity *number of days of physical activity corresponding to intensity per week* time) [ 30 ].…”
