Abstract

BACKGROUND AND OBJECTIVES
This study was performed to elucidate the relationship between body mass index (BMI) and snoring time (ST) in patients with obstructive sleep apnea (OSA) using a portable sleep monitoring device.
SUBJECTS AND METHOD
From May 2011 to December 2015, 492 patients whose apnea-hypopnea index (AHI) was more than 5 were enrolled. Subjects were classified into 3 groups on the basis of the AHI (mild=5≤AHI<15; moderate=15≤AHI<30; severe=30≤AHI). Using the multiple linear regression analysis, the relationship between ST and other variables (BMI, arousal index, O2 desaturation events, age and AHI) were measured in each group.
RESULTS
There was significant association between ST and BMI, especially in the severe group (p=0.005).
CONCLUSION
In the severe group, reducing BMI is important to improve ST.
