Abstract

OBJECTIVES
This study assessed the accuracy of the 24-hour diet recall method for estimating the energy intake of elderly men using the doubly labeled water as a reference method.
METHODS
Seventeen subjects (mean age 72.5 ± 3.9 years), who maintained the same body weight during the two weeks study period, were included in this study. Three 24-hour diet recalls (two weekdays and one weekend) were obtained over a 14 day period to estimate the mean energy intake. The total energy expenditure was measured over the same 14 days using the doubly labeled water method. The total energy intake and total energy expenditure were compared by paired t-test.
RESULTS
The total energy intake from the 24-hour diet recalls method was 2536.7 ± 350.6 kcal/day, and the total energy expenditure from the doubly labeled water method was 2659.8 ± 306.8 kcal/day. The total energy intake was slightly under-reported by −123.2 ± 260.8 kcal/day (−4.4%). On the other hand, no significant difference was observed between the total energy intake and total energy expenditure of the subjects (p=0.069). The percentage of accurate predictions was 64.7%. The correlation between the total energy intake and total energy expenditure was statistically significant (r=0.697, p < 0.005).
CONCLUSIONS
The present study supports the use of the 24-hour diet recall method to estimate the mean energy intake in elderly men group. More studies are needed to assess the validity of 24-hour diet recall method in other population groups, including elderly women, adults and children.
