Underestimation of Energy Intake Using 24-Hour Recall by Korean Urban Elders

To investigate the underreporting of total energy intake, we analyzed the one-day dietary intake data collected by 24-hour recall method from 381 Seoul- and Ansung-dwelling older adults (≥60y) in Korea. Underreporting was addressed by computing the ratio of energy intake (EI) to the estimated basal metabolic rate (BMRest) from age- and gender-specific equations of Schofield. EI:BMRest ratio was found to be 1.41 for men and 1.22 for women, with about 12 percent of men and 19 percent of women classified as under reporters. Underreporting of energy intake was higher in men who were trying to lose weight, smokers, women who consumed alcohol, and in both sexes who were in poor health or had suffered from depression in the last year. For men, the most significant variables to predict the ratio of energy intake to estimated basal metabolic rate (EI: BMRest) were age and attempts to lose weight, whereas smoking, weight status, and education were most significant for women.
