The validity of the Stanford Seven-Day Physical Activity Recall in young adults.
PURPOSE To evaluate the criterion validity of the 7-Day Physical Activity Recall ( 7D-PAR ) and factors associated with reporting error , in a sample of moderately overweight , young adult men and women . METHODS Average total daily energy expenditure ( TDEE ) and physical activity energy expenditure ( PAEE ) from the 7D-PAR were compared with the same parameters assessed by doubly labeled water in 17 men , age = 23.9 + /- 3.8 yr , and 29 women , age = 23.3 + /- 4.6 yr , who volunteered to participate in a 16-month supervised aerobic exercise trial .  PAEE was estimated from the 7D-PAR and from DLW [ 0.9 * TDEE -resting metabolic rate ( RMR ) ( indirect calorimetry ) ] . In addition , peak oxygen uptake and percent body fat were obtained . RESULTS No significant differences in TDEE ( kJ.d-1 ) were noted between the 7D-PAR ( 11825 + /- 1779 ) and DLW ( 11922 + /- 2516 ) for the complete sample ( N = 46 ) or for men ( 7D-PAR = 13198 + /- 1638 , DLW = 13885 + /- 2754 ) or women ( 7D-PAR = 11018 + /- 1323 , DLW = 10771 + /- 1457 . The mean PAEE from the 7D-PAR was not different from DLW in the total sample ( 7D-PAR = 3286 + /- 502 , DLW = 3508 + /- 1863 ) as well as in men ( 7D-PAR = 3650 + /- 490 , DLW = 3989 + /- 2461 ) and women ( 3073 + /- 377 , DLW = 3223 + /- 1360 ) . In a regression model , PAEE , peak oxygen uptake , gender and percent fat accounted for 86 % of the reporting error in total daily energy expenditure when using the 7D-PAR . CONCLUSION The 7D-PAR provided a reasonable estimate of both the mean TDEE and PAEE in this sample ; however , estimates of energy expenditure on an individual basis using the PAR were subject to considerable error
