阻塞型睡眠呼吸中止症候群（Obstructive Sleep Apnea-Hypopnea Syndrome, OSA）的患者，睡眠時會因呼吸中止而缺氧，近年來中醫治療本病，均認為應對證下藥，其關鍵在於患者體質之確診。以往中醫診斷主要依據臨床經驗及主觀判斷，本研究使用病人自填式問卷調查作為輔助，期能有較客觀的依據。研究團隊於2011 年4 月至6 月間，於睡眠中心門診進行調查，累積確診為中重度OSA的患者共40 例。患者主要年齡分佈介於30 至60 歲之間；OSA患者治療前之體質，最常見者為痰濕（77.5%）、氣虛（75%）、陰虛（52.5%）、濕熱（42.5%）等類型；同時可看出具有偏頗體質的受訪者，具有較高的「睡眠呼吸暫停- 低通氣指數」（Apnea-Hypopnea Index, AHI）與「身體質量指數」（Body Mass Index, BMI）。The obstructive sleep apnea syndrome (OSA) patients would get episodes of breathing cessation or absence of respiratory airflow. In recent years, the TCM treatments of OSA were according to the patients’ patterns. The key point is diagnosis of patients’ constitutional patterns. In past, the diagnosis patterns of OSA were according to the doctors’ clinical experience and subjective diagnosis. In order to get more objective basis, this study use the Patient self -assessment questionnaire of Wang’s TCM constitution scale. We have surveyed 40 middle-to-severe OSA patients at the clinic in the sleep center from April to June, 2011. The main distribution of ages was among 30 to 60 years old. The main constitutional patterns are Phlegm-Dampness (77.5%), Qi-deficiency (75.0%), Yin-deficiency (52.5%), Dampness- Heat (42.5%). At the same time, we also observed that the patient having the biased constitution were with higher Apnea-Hypopnea Index and Body Mass Index.
