- W3040891851 abstract "PURPOSE: To cross-validate PPAQ, a valididated physical activity (PA) recall questionnaire, for the Chinese college students. METHODS: 166 (99 males & 67 females; Age = 18.6 ± 1.1 yr., Height = 170.6 ± 8.4 cm, Weight = 63.3 ± 12.4 kg, BMI = 21.6 ± 3.1) Chinese college students’ 7-day energy expenditure (EE) data were estimated using ActiGraph wGT3X-BT accelerometers. They were also asked to recall their PA using PPAQ before and after the accelerometer data collection. Total EE, walking steps, light, moderate, vigorous, very vigorous and moderate-to-vigorous PA (MVPA) time, estimated by ActiGraph were compared with EE derived from PPAQ and test-retest reliability was computed also for PPAQ. RESULTS: All subjects wore the accelerometer for at least 10 hr. a day and over 4 days in one week. The correlation between the accelerometer total EE and that reported by PPAQ is 0.308 (p<0.001), accelerometer walking and that reported by PPAQ is 0.361(p<0.001), which were low, but consistent with the validity reported for the questionnaire method. The test-retest reliability coefficient of PPAQ is 0.761. In average, the Chinese college student’ PA are: Weekly Total EE =1778.41 ± 1003.76 (kcals), Daily EE =142.93 ± 85.85 (kcals),Weekly walking Steps = 38730.02 ± 15506.72 (steps), Weekly total MVPA = 347.2 ± 144.4 (minutes), Daily MVPA 28.06 ± 14.71 (minutes), Weekly Average PA intensity METs = 1.14 ± 0.07(METs), according to the ActiGraph. CONCLUSION: Similar validity and reliability of PPAQ were confirmed for the Chinese college student sample and they met the PA guideline." @default.
