한국 성인 남성에서 체질량지수를 이용한 현재의 비만 기준과 중증 수면무호흡과의 상관관계

Background and Objectives: We tried to assess the effect of body mass index (BMI) on obstructive sleep apnea (OSA) in Korean male patients by using portable polysomnography. Materials and Methods: We evaluated 796 patients whose Apnea+hypopnea index (AHI) were over 5 as the result of overnight portable polysomnography from September 2011 to December 2016. The subjects were classified into 2 groups on basis of the AHI severity : A group : 5≤AHI<30 ; B group : 30≤AHI. The subjects were classified into 3 groups on basis of the BMI : X group : BMI<25 ; Y group : 25≤BMI<27.7 ; Z group: 27.7≤BMI. By multiple logistic regression analysis, we studied the relationship of AHI as dependent variable to BMI and age in each group. Results: There was significant correlation between 30≤AHI group and 27.7≤BMI group (odds ratio, 3.443 ; p< 0.01). Conclusions: Weight reduction is more needed in the 27.7≤BMI group due to the risk of 30≤AHI in Korean male OSA patients. (J Clinical Otolaryngol 2018;29:53-56)
