Background & Aim: Anorexia nervosa (AN) is a kind of mental disorder which is mortal in the serious case mainly seen among young adults. Anorexia nervosa is classified into anorexia nervosa restricting type (ANr) and binge eating/purging type (ANbp). Patients need to have counseling by registered dietitians for nutrient intake. The assessment of their food intake is based on basal energy expenditure (BEE). In this study, we tried to obtain the value of BEE calculated by equation which is most accurate to estimate BEE in AN patients. Method: Exhalation analyses were conducted by the apparatus (CHESTAK, C-8800, Chest M. I. Inc., Japan) in the patients of AN, ANr (n=13) and ANbp (n=10). The values of BEE evaluated by exhalation analysis were compared with the values calculated by Harris- Benedict equation and also compared with the values calculated by equation indicated in Dietary Reference Intakes 2010 in Japan (DRI), kcal/kg/day�?�?body weight. Two-tailed studentâ�?�?s t-test, followed by the F-test checking variance was performed and p<0.05 was considered significantly different. Results: In ANr (n=13), the values of BEE measured by exhalation analysis was 737�?±210 kcal/day, the values calculated by Harris- Benedict equation was 1.177�?±132 kcal/day (p<0.05). In ANbp (n=10), 815�?±136 kcal/day and 1.088�?±30 kcal/day (p<0.05), respectively. On the other hand, the value of BEE calculated by the equation in DRI was 794�?±167 kcal/day in ANr and 735�?±62 kcal/day in ANbp and there was no significant difference to the values measured by exhalation analysis. Conclusion: The values of BEE in AN patients can be estimated by those calculated by the equation in DRI, which will be more useful and reliable to support AN patients in counseling on nutrient intakes.
