The comprehensive physical activities for the
past 7 days, including leisure time, indoor and outdoor
work and transportation related activities were
measured by using IPAQ. Information about frequencies
and duration of each activity were collected and
scores summated to reflect the total physical activities
conducted. Test-retest correlation coefficient for
1-week intervals was 0.65 and Spearman’s reliability
coefficient was 0.76 (Ainsworth et al., 2000)
