| Crohn’s disease (n=12, 8M/4F) | Anorexia nervosa (n=19, 0M/19F) | p Value | |
| Age (y) | 13.8 (1.7) | 15.6 (4.2) | 0.0057 |

| Weight (kg) | 37.5 (5.9) | 41.6 (5.9) | 0.07 |
| REE (kcal/day) | 1254 (210) | 1021 (117) | 0.003 |
| REE (%predicted) | 97.8 (11.4) | 77.8 (11.8) | 0.0001 |
| REE/LBM | 38.5 (4.3) | 28.2 (5.2) | 0.00001 |
Values are expressed as mean (SD).
IBW, ideal body weight; REE, resting energy expenditure; LBM, lean body mass.
LBM was determined from H2 18O dilution.
