摘 要：Purpose To compare physical activity and sedentary behavior between four commonly used subjective and objective meas-ures:the 7-day Physical Activity Recall (7DPAR),International Physical Activity Questionnaire (IPAQ),pedometer,and *** A total of 130 college students completed four measures for the same 7 *** composition was measured using a bioelectric impedance *** signed rank tests and Spearman correlations were performed to compare estimates between activity *** Spearman correlations between different activity measures were further examined separately for the higher and the lower body fat *** Compared with accelerometer-derived data,both the 7DPAR and the IPAQ overestimated light physical activity(P 0.001) while underestimated sedentary behavior (P 0.001).Across comparisons,the highest correlation was found between accelerometers and pedometers on steps/day (r =0.72,P 0.001).The 7DPAR and the IPAQ were correlated with each other for all physical activity variables and sedentary behavior (r =0.37-0.45).There were low correlations (r=0.20-0.47) between the 7DPAR,the IPAQ,and accelerometers in sedentary behavior,light physical activity,and vigorous physical *** correlations between different activity modalities were observed among individuals with lower body fat(r=0.41-0.80) than among those with higher body fat (r=0.31-0.65).Conclusions The 7DPAR and the IPAQ yielded comparable estimation of moderate physical activity relative to *** were significant differences in sedentary time across activity *** compositions should be considered when comparing the estimates of activity levels between subjective and objective instruments.
