目的:根据睡眠磨牙症(SB)和阻塞性睡眠呼吸暂停(OSA)的严重程度,估计其统计学和流行病学关联。并描述所分析人群中的睡眠数据结果。
方法:对有和没有OSA的受试者进行病例对照研究(N=37)。所有受试者都在圣卡洛斯大学医院的睡眠室(临床神经生理学系)进行了通宵多导睡眠图记录。使用ICSD-3和AASM-2.6评分确定OSA的诊断和严重程度。明确的SB诊断是通过自我报告测试获得的,体检,和PSG录音。用于研究这两种情况之间的关联的变量包括呼吸暂停和呼吸不足发作,呼吸暂停低通气指数(AHI),每晚SB发作的次数,还有磨牙症指数.Chi2,相关性,并计算方差分析。使用OR计算流行病学关联。
结果:SB显示与OSA有流行病学关联,OR为0.15(0.036-0.68),这表明它可以被认为是一个保护因素(p<0.05)。OSA患者的平均SB发作(6.8±12.31)比非OSA患者(25.08±31.68)少。SB发作与AHI和呼吸不足的数量呈负相关(p<0.05)。轻度OSA患者的SB平均发作次数明显高于重度OSA患者。
结论:在这个亚临床和轻度OSA患者样本中,SB可以作为保护因素。然而,用更大的样本量来确认这些结果是必要的。
OBJECTIVE: To estimate the statistical and epidemiological association between Sleep bruxism (SB) and Obstructive sleep apnea (OSA) based on OSA severity, and to describe sleep data findings within the analyzed population.
METHODS: A
case-control study (N = 37) was conducted on subjects with and without OSA. All subjects underwent a full-night polysomnographic recording at the Sleep Unit (Clinical Neurophysiology Department) of San Carlos University Hospital. The diagnosis and severity of OSA were determined using ICSD-3 and AASM-2.6 scoring. The definitive SB diagnosis was obtained through a self-report test, physical examination, and PSG recordings. Variables used to study the association between both conditions included the apnea and hypopnea episodes, the Apnea-hypopnea index (AHI), the number of SB episodes per night, and the bruxism index. Chi2, correlations, and ANOVA were calculated. The epidemiological association was calculated using the OR.
RESULTS: SB showed an epidemiological association with OSA, with an OR of 0.15 (0.036-0.68), suggesting it could be considered a protective factor (p < 0.05). OSA patients presented fewer average SB episodes (6.8 ± 12.31) than non-OSA patients (25.08 ± 31.68). SB episodes correlated negatively (p < 0.05) with the AHI and the number of hypopneas (p < 0.05). The average number of SB episodes was significantly higher in patients with mild OSA compared to those with severe OSA.
CONCLUSIONS: In this sample of patients with subclinical and mild OSA, SB may act as a protective factor. However, confirmation of these results with a larger sample size is necessary.
