Adequate nutrition is important in maintaining optimal health. Malnutrition can expose individual to increased risks of morbidity and mortality. The purposes of this study were to determine the basal energy expenditure (BEE) of Korean healthy subjects and TPN patients using Bioelectrical Impedance Analysis (BIA) method and to compare these values with those predicted by Harris-Benedict equation (H-B). BEE values measured by BIA were compared with predicted BEE values by the H-B formula in 59 clinically stable TPN patients and 65 healthy volunteers. In healthy volunteers and TPN patients, statistically significant differences were not shown between the BEE values measured by BIA (1392.5 Kcal and 1325.9 Kcal) and those predicted by H-B formula (1384.1 Kcal and 1270.1 Kcal). In male volunteers, statistically significant differences were not shown between BEE values measured by BIA (1670.7 Kcal) and the H-B formula (1550.9 Kcal), but in female volunteers, statistically significant differences were shown between BEE values measured by BIA (1194.8 Kcal) and the H-B formula (1265.6 Kcal). In male TPN patients, statistically significant differences were shown between BEE values measured by BIA (1453.5 Kcal) and the H-B formula (1335.9 Kcal), but in female TPN patients, statistically significant differences were not shown between BEE values measured by BIA (1126.4 Kcal) and the H-B formula (1167.2 Kcal). In normal healthy volunteers, of BEE values measured by BIA and in TPN patients of BEE values measured by BIA were within of BEE values predicted by the H-B formula in non-obese subjects. In conclusion, BEE values predicted by H-B formula or measured by BIA can be applied to non-obese Koreans. However, these values should be confirmed with Indirect calorimetry for Koreans.
