Abstract

|

Background: The purpose of this study was to compare the Physical Activity Recall (Stanford 7-days physical activity recall) with the Triaxial accelerometer (RT3) to assess physical activity in young adults.
Methods: Thirty-seven subjects wore the RT3 for 24 hours and then completed the physical activity recall. The Stanford 7-Day Recall records hours of sleep, light-, moderate-, hard- and very hard levels of physical activity.
Results: The total energy expenditure per day for the Stanford 7-day recall and RT3 was 2381.29⁑594.93 kcal/day and 2232.97⁑398.32 kcal/day, respectively, and showed high correlation (r=0.821). The activity energy expenditure per day for the Stanford 7-day recall and RT3 was 836.21⁑290.5 9 kcal/day and 509.83⁑181.57 kcal/day, respectively, and showed less high but significant correlation (r=0.327). When compared by sex, the total energy expenditure was significantly correlated in men (r=0.572) and the activity energy expenditure in women (r=0.484).
Conclusion: The Stanford 7-day recall and the RT3 was highly correlated in the total energy expenditure and significantly correlated in the activity energy expenditure. Therefore, it may be used reciprocally to assess physical activity. (J Korean Acad Fam Med 2005; 26:74-80)
