文本框: RESTING ENERGY EXPENDITURE IN PATIENTS WITH OBSTRUCTIVE SLEEP APNOEA Li A M, Yin J, Fok T F Department of Paediatrics, Prince of Wales Hospital, Shatin, Hong Kong, SAR, China Objective: To determine how resting energy expenditure (REE) is affected in the patients with obstructive sleep apnoea (OSA). Methods: Patients with confirmed OSA secondary to adeno-tonsillary hypertrophy and control subjects matched for age, sex and ideal weight for body height were recruited from the Paediatric Chest clinic. All subjects underwent REE measurement by open-circuit indirect calorimetry using a metabolic cart and canopy system (Sensor Medic 2900Z, Sensor Medics Corp., Yorba Cinda, Calif.). The measurements were taken during slow-wave sleep. Results: Twenty-four cases with OSA (Apnoea-hypopnoea index > 5) and twenty-three control subjects were studied. Their mean age was 9.4 years (SD 3.9). REE corrected for body weight for the cases and the control group were 44.83 (SD 10.49) Kcal/day and 40.71 (SD 10.60) Kcal/day respectively (p > 0.05). REE was not found to be associated with the severity of OSA (Pearson correlation r=0.34, p=0.27). Conclusion: REE was greater in OSA patients than controls but the difference was not statistically significant. 1927
