Validation of estimated energy requirement equations in adults 40 years and older using resting energy expenditure and physical activity level

초록/요약 도움말

Objectives: This study evaluate total energy expenditure(TEE) of Korean adults in their 40s and older using an indirect calorimeter and physical activity classification table and compare it with the estimated energy needs of these people as suggested by Dietary Reference Intakes for Koreans(KDRI). Methods: A total of 74 (male 40, female 38) adults and older were incuded. Resting energy expenditure(REE) was measured by indirect calorimetry. A 24-hour physical activity diary was kept for three days (two days during the week and one day on the weekend). PAL was calculated from the physical activity classification table (PACT). Results: The mean age of the study participants was 55.7 ±7.0 years. Also there was difference between men and women of REE using indirect calorimetry, that of men was 1,575.9±167.5kcal/day and women was 1,251.2±106.9kcal/day. Man (EER 2,606.7±386.9 kcal/day; TEE 2,656.4±500.0 kcal/day) and women (EER 2,027.1±217.3 kcal/day; TEE 2,092.2±288.3kcal/day) were significantly higher in women. The KDRI equations for EER underestimated TEE by 11.1% and 24.0% in man and women. The percentages of accurate predictions among subjects were 76.3% in men and 53.7% in women. Conclusion: The finding of this study suggest that the KDRI’s equation for EER result in the underestimating and overestimating the adults in their 40s and older woman. Future studies including different population should be carried out to develop KDRI’s EER accurate predictive equations for Korean adults.
