Résumé : Monitoring parameters for anorexia nervosa include clinical, biological and psychological factors. Many research groups are currently trying to identify parameters more likely to predict the severity or the evolution of the illness. Body composition has been proposed as one of those parameters. The aim of the present study is to demonstrate that measures of body composition are more accurate and efficient than the use of body composition index (BMI). We also aim to show that body composition could be used as a prognostic factor in the long-term evolution of patients with anorexia nervosa. It's a retrospective study investigating body composition and BMI in 44 patients treated in a specialized unit for eating disorder. Measures of body composition and BMI were gathered at the time of admission and again 3 months after refeeding onset. Data was correlated to the EDI-2 questionnaire scores. BMI and %FM where found to be increased (P < 0.05) between admission and after 3 months refeeding. The double objective of reaching a BMI value ≥ 20 kg/m2 and a %FM value ≥ 24% was achieved by 22% of patients. No significant correlation was found between EDI-2 scores and measures of BMI and %FM either on admission or after the 3 months refeeding period. In conclusion, results of our study don't allow concluding for a prognostic superiority of %FM. Nonetheless, BMI currently used as a reference for the monitoring of eating disorders patients seems to lack sensitivity where measures of body composition seem more informative regarding nutritional status. Furthermore, fat mass plays an important role in other clinical manifestations. In addition, measures of body composition should allow more individualised therapeutic support.
