Comparison of Predicted and Measured Resting Energy Expenditure in Overweight and Obese Korean Women: Ji Sook Park, Jung Eun Yim; Korean J Community Nutr 2018;23(5):424-430. Published online October 31, 2018; DOI: https://doi.org/10.5720/kjcn.2018.23.5.424

OBJECTIVES
The purpose of this study was to compare predictions and measurements of the resting energy expenditure (REE) of overweight and obese adult women in Korea.
METHODS
The subjects included 65 overweight or obese adult women ranging in age from 20~60 with a recorded body mass index (BMI) of 23 or higher. Their height, weight, waist-hip ratio, and blood pressure were measured. The investigator also measured their body fat, body fat percentage, and body composition of total weight without fat using Dual energy X-ray absorptiometry (DXA) and measured resting energy expenditure by indirect calorimetry. Measured resting energy expenditures were compared with predictions from six methods: Harris-Benedict, Mifflin, Owen, WHO-WH, Henry-WH, and KDRI.
RESULTS
Harris-Benedict predictions showed the smallest differences from measured resting energy expenditure at an accurate prediction rate of 70%. The study analyzed regression between measured resting energy expenditure and body measurements including height, weight and age. The formula proposed by this research is as follows: Proposed REE equation for overweight and obese Korean women = 721 âˆ’ (1.5 Ã— age) + (0.4 Ã— height) + (9.9 Ã— weight).
CONCLUSIONS
These findings suggest that age is a significant variable when predicting resting energy expenditure in overweight and obese women. Therefore, prediction of resting energy expenditure should consider age when determining energy requirements in overweight and obese women.

A Comparison of Energy Intake and Energy Expenditure in Normal-Weight and Over-Weight Korean Adults: Jung A Park, Ki Jin Kim, Jin Sook Yoon; Korean J Community Nutr 2004;9(3):285-291. Published online June 30, 2004

Abstract PDF: The purpose of this study was to compare the energy expenditure and energy intake of normal-weight and overweight Korean adults. We recruited 242 adults to determine resting energy expenditure, physical activity and energy intake. Resting energy expenditure was measured by indirect calorimetry. Energy intake for consecutive two days was assessed by 24 hour recall method. Daily activity pattern for 24 hour was collected from each subject. Body weight, lean body mass and percentage body fat were measured by INBODY 3.0. The subjects were divided into normal (20 < or = BMI < 25) and overweight (BMI > or = 25) groups by BMI. There was no significant difference in intake of energy between two groups. Energy intake of each group was lower than the 7th Korean RDA of energy. Overweight subjects showed significantly lower REE/kg body weight. However, REE/kg lean body mass (LBM) did not differ between the two groups. Total activity energy was significantly higher in the overweight group compared to the normal group. Daily activity coefficient of overweight group in male was lower than that of normal group. Daily activity coefficient was almost same in two female groups. LBM was highly correlated with REE and total energy expenditure. We concluded that the overweight group consumed more energy than the normal group due to the heavier body weight.

A Comparison of the Resting Energy Expenditure of Korean Adults Using Indirect Calorimetry: Jung A Park, Ki Jin Kim, Joung Hee Kim, Young Sook Park, Jaeok Koo, Jin Sook Yoon; Korean J Community Nutr 2003;8(6):993-1000. Published online December 31, 2003

Abstract PDF: The purpose of this study was to provide baseline data for revising the recommended energy intake for Korean adults. We recruited 290 adults so as to determine their resting energy expenditure (REE) and energy intake. The REE was measured by indirect calorimetry. We also calculated the REE from prediction equations formulated by World Health Organization (WHO). The energy intake for two consecutive days was assessed using the 24 hour recall method. The body weight, lean body mass (LBM) and percentage body fat were measured using the INBODY 3.0 system. We compared the results of three age groups; 20 to 29 years, 30 to 49 years and 50 years or more. The average energy intake of each age group was below the 7th Korean Recommended Dietary Allowances (RDA). The average energy intake was lower in the older age groups. However, no difference was observed among the age groups when the energy intake as a percentage of the Korean RDA was compared. Our measurement of the REE was higher than the REE calculated by the WHO's method. Correlation coefficients between the measured and the calculated values of REE for all age groups showed significant correlations (r = 0.475-0.672). As the ages of all the subjects increased, the REE/kg of body weight decreased. There were no significant differences in the REE / kg of the LBM between the different age groups; however, the REE/kg of the LBM was higher in the female group than in the male group. Negative correlations of the REE with the age (r = -0.242) and body fat ratio (r = -0.313) were observed; positive correlations of the REE with the BMI (r = 0.265), height (r = 0.570), weight (r = 0.562) and LBM (r = 0.586) were also found (p < 0.01).
