Objective and Subjective Physical Activity Measurement

The daily behavior domain employed two methods to assess DB patterns regarding physical activity and had 30 points, with daily step counts accounting for 25 and self-reported PA accounting for the remaining 5 points. An objective method used pedometers to count steps, and a subjective method used a self-administered question on how many days a person engages in PA (MVPA) for 60 min per week. Daily steps were measured using Yamax DigiWalker SW-200 pedometers (Yamax Corporation, Tokyo, Japan). The participants were given pedometers to wear over their right side hip bone, fastened to the waistband of their trousers (pants for boys and shalwar for girls) for seven consecutive days. The first day the children received their pedometers was designated as a “practice day”. For the following seven days, except for the day used for practice, kids or parents recorded their daily step count before turning it in for the night. They recorded the entire time the pedometer was removed throughout the day on the log sheet. Moderate to vigorous physical activity (MVPA) was measured with one item from the CAPL-2 questionnaire. Participants self-reported the number of days they engaged in MVPA for at least 60 min per week [31 ,46 (link)].
