目的:目的是确定睡眠磨牙症(SB)的患病率和危险因素,并调查SB发作之间的关系。唤醒,阻塞性睡眠呼吸暂停(OSA)成人的呼吸事件。
方法:这项前瞻性研究包括914名患有OSA的成年人(305名女性,609名男性;年龄=53岁[四分位距=17];呼吸暂停低通气指数=13.9事件/h[四分位距=21])。根据完整的多导睡眠记录,当节律性咀嚼肌活动(RMMA)指数至少为2次/小时睡眠时,就可以诊断为SB。采用二元Logistic回归分析确定SB的危险因素。进行了网络分析,以确定RMMA之间的关系,呼吸事件,睡眠唤醒,和其他因素。Further,计算与觉醒相关的RMMA时间百分比.
结果:成人OSA中SB的患病率为49.7%。男性,较低的体重指数,和更高的N1睡眠百分比增加了SB的几率(比值比分别为1.425、0.951和1.032;所有P<.05)。网络分析显示RMMA与呼吸暂停低通气指数无直接关联,也不在RMMA和唤醒之间,尽管85.7%的RMMA与唤醒时间相关。
结论:将近一半的OSA成年人患有共病SB。男性,较低的体重指数,轻度睡眠的比例越高,患SB的风险就会增加。尽管RMMA与呼吸事件和觉醒没有直接关系,大多数RMMA与OSA成人的觉醒时间相关。

The aim was to determine the prevalence and risk factors of sleep bruxism (SB) and to investigate the relationships between SB episodes, arousals, and respiratory events in adults with obstructive sleep apnea (OSA).
This prospective study included 914 adults with OSA (305 females, 609 males; age = 53 years [interquartile range = 17]; apnea-hypopnea index = 13.9 events/h [interquartile range = 21]). The diagnosis of SB was made when the rhythmic masticatory muscle activity (RMMA) index was at least 2 episodes/h of sleep based on a full polysomnographic recording. Binary logistic regression was performed to identify risk factors for SB. Network analysis was performed to determine the relations between RMMA, respiratory event, sleep arousal, and other factors. Further, the percentage of RMMA time-related to arousal was calculated.
The prevalence of SB in adults with OSA was 49.7%. Male sex, lower body mass index, and higher percentage of N1 sleep increased the odds of having SB (odds ratios = 1.425, 0.951, and 1.032, respectively; all P < .05). Network analysis showed that there were no direct associations between RMMA and apnea-hypopnea index, nor between RMMA and arousal, although 85.7% of RMMA was time-related to arousals.
Nearly half of adults with OSA have comorbid SB. Male sex, lower body mass index, and a higher percentage of light sleep increase the risk of having SB. Although RMMAs do not directly correlate with respiratory events and arousals, most RMMAs are time-related to arousals in adults with OSA.
