阻塞性睡眠呼吸暂停病人的能量代谢特点及饮食疗法

Energy metabolism and diet therapy in OSA patients

目的：研究中、重度阻塞性睡眠呼吸暂停（OSA）病人经鼻面罩持续正压通气（CPAP）治疗前、后能量代谢的变化，提出OSA病人控制体重的独特方法。方法：30例中、重度OSA病人分别于cPAP治疗前后测量1—2期睡眠时的静息能量消耗（REE）及体重。随机选取性别、年龄、身高、体质指数均与之相当的我院健康职工为对照组。结果：OSA病人1～2期睡眠时的REE较对照组增高，经CPAP治疗后下降（P〈0．01）。结论：OSA病人的机体代谢率增高，高代谢促使摄食量增多，体重进一步增加。建议OSA病人减轻体重在cPAP治疗基础上控制饮食。

Objective：To study the characteristic of energy metabolism in moderate and severe OSA before and after CPAP. Methods ： The REE was measured before and after 5-8 week treatment by CPAP in OSA patients. Health staff of single obesity in the hospital were as control. Results ： During sleep, the enengy-metabolism was increased significantly in OSA patients. After treatment by CPAP, it was decreased （P 〈 0.01 ）. Conclusion：The OSA patients are on high metabolism, then resulting in over feeding and the increase of body weight . So we suggest that the OSA patient should control diet on the CPAP treatment.
