The Analysis of Activity Energy, Total Energy, and Estimated Energy Expenditures in 5th and 6th Grade Primary School Students: Mi Jeong Kim, Hyeon Ju Na, Youngnam Kim; Korean J Community Nutr 2011;16(2):195-205. Published online April 30, 2011; DOI: https://doi.org/10.5720/kjcn.2011.16.2.195

This study was conducted to investigate the time spent, activity coefficient and energy expenditure on 7 different types of activity. Total of 386 5th and 6th grade primary school boys and girls in Seoul participated in this study. The participants spent 8 hrs for rest, 4 hrs for out of school study, 3 hrs for leisure, 1 hr 45 mins. for hygiene, 1 hr for commute, and 15 mins. for house choir activity in the day of 6 class hours. The average activity coefficient of 1 day for boys and girls were 1.69 and 1.64, respectively. The TEEs were 2,382 kcal and 2,050 kcal for boys and girls, respectively. The energy cost for study related activity (in school and study activities) was 40% of the TEE, and for rest 20%, for commute 9%, and for hygiene 10% of the TEE. The energy cost for house choir was only about 2% of TEE. The 91.2% participant's EER was higher than the EER shown in the table of 2010 DRI for Koreans. When the participant's EER was compared with the energy allowance calculated by the method in 2000 RDA for Korean, 81.6% was in the range of +/- 5%, and the correlation coefficients between the 2 values were 0.981 for boys and 0.978 for girls, which means high agreements.

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.
