Abstract

The study was conducted to assess the energy expenditure of 102 elementary school children. Body weight and height were measured and one-day activity diaries were collected by interviewing with children. The children spent about 9 hours 14 minutes sleeping ; 3 hours 40 minutes resting. They spent 86.4% of 24 hours (one day) in 'very light activities' and 13.3% in 'light activities'. Activity coefficient (1.41$\pm$0.11) of boys was significantly higher than that of girls(1.35$\pm$0.07). Activity coefficient (1.41$\pm$0.11) of 4th grade elementary school children was higher than those of 2nd and 6th grade school children(p<0.05). Resting energy expenditure estimated by Harris-Benedict formula, formula based on body surface area and DRI formula for Koreans were 1240.9$\pm$147.4kcal/day, 1386.5$\pm$206.9kcal/day and 1284.5$\pm$199.8 kcal/day. And daily energy expenditure by using Harris-Benedict formula, body surface area formula and DRI formula were 1708.4$\pm$258.8kcal, 1909.8$\pm$341.8kcal and 1771.1$\pm$341.9kcal/day. These results suggested that nutrition and exercise program to increase the energy expenditures of primary school children should be developed.
