Abstract：
OBJECTIVE: To investigate the prevalence of sleep bruxism (SB) in Thai obstructive sleep apnea (OSA) patients and to identify demographic characteristics and specific sleep parameters associated with SB.
METHODS: A total of 119 medical records, each containing full-night type I polysomnography from Thai patients with OSA, were included. SB was detected using surface electromyography of the masseter muscle. SB was diagnosed when the SB index reached at least two episodes per hour of sleep. The differences in demographic characteristics and sleep parameters between SB and non-SB groups were analysed. Multivariate logistic regression analysis was performed to determine the associated factors for SB.
RESULTS: Among Thai patients diagnosed with OSA, 50.4% concurrently experienced SB, predominantly of the tonic type. The study revealed a higher prevalence of SB in males compared to females. The SB group demonstrated significantly higher values in the apnea-hypopnea index (AHI), Epworth Sleepiness Scale (ESS), Arousal Index (AI), and Respiratory Arousal Index (RAI) compared to the non-SB group. Multivariate logistic regression analysis indicated that a lower body mass index (BMI), higher ESS, and increased severity of AHI were significantly associated with SB.
CONCLUSIONS: The study revealed that half of Thai patients diagnosed with OSA also exhibited SB. Male, AHI, ESS, AI, and RAI appeared to be potential correlates for the presence of SB. Lower BMI, higher ESS, and elevated AHI can be factors associated with SB in Thai OSA patients.
CONCLUSIONS: The prevalence of SB among Thai patients diagnosed with OSA and the factors associated with its occurrence were investigated.

摘要：
目的：调查泰国阻塞性睡眠呼吸暂停（OSA）患者中睡眠磨牙症（SB）的患病率，并确定与SB相关的人口统计学特征和特定睡眠参数。
方法：共119份病历，每个包含来自泰国OSA患者的全夜I型多导睡眠图，包括在内。使用咬肌的表面肌电图检测SB。当SB指数达到每小时睡眠至少两次发作时，就诊断出了SB。分析SB组和非SB组之间人口学特征和睡眠参数的差异。采用多因素logistic回归分析确定SB的相关因素。
结果：在诊断为OSA的泰国患者中，50.4%同时经历SB，主要是补品型。研究表明，男性的SB患病率高于女性。SB组的呼吸暂停低通气指数（AHI）明显较高，Epworth嗜睡量表（ESS），觉醒指数(AI)，和呼吸觉醒指数（RAI）与非SB组比较。多因素logistic回归分析表明，较低的体重指数（BMI），较高的ESS，AHI严重程度增加与SB显著相关。
结论：研究显示，一半被诊断为OSA的泰国患者也表现出SB。男性,AHI,ESS,AI,RAI似乎是SB存在的潜在相关因素。较低的BMI,较高的ESS，AHI升高可能是与泰国OSA患者SB相关的因素。
结论：调查了泰国OSA患者中SB的患病率及其发生的相关因素。
