Stress is discussed as a potential factor in the development of sleep bruxism (SB). The aim of this study was to investigate whether specific stress-factors correlate with SB-activity.
Sixty-nine subjects, of which 48 were SB-patients, completed three German questionnaires assessing different stress-parameters and stress-coping-strategies: Short questionnaire for recognition of stress-factors (Kurzer Fragebogen zur Erfassung von Belastungen, KFB), Questionnaire for recuperation and strain (Erholungs-Belastungs-Fragebogen, EBF-24 A/3) and the stress-coping questionnaire (Stressverarbeitungsfragebogen-78, SVF-78). The diagnosis of SB was based on the clinical criteria of the American Academy of Sleep Medicine (AASM). The degree of SB-activity was measured by the Bruxcore-Bruxism-Monitoring-Device (BBMD, Bruxcore, Boston, USA), worn for five consecutive nights and analyzed using a computer-based method. Non-parametric Spearman correlation coefficients, rho, were calculated between the psychometric data and the amount of SB-activity measured by a pixel score of the BBMD.
Significant correlations were found for 'daily problems' (r = 0.461, p < 0.01), 'trouble at work' (r = 0.293), 'fatigue' (r = 0.288), 'physical problems' (r = 0.288) and the coping-strategy 'escape' (r = 0.295) (all p < 0.05).
Within the limitations of this study it could be shown that subjects with high SB-activity tend to feel more stressed at work and in their daily life, which in turn might influence their physical state. These subjects also seem to deal with stress in a negative way. However, due to the rather low to almost moderate correlation coefficients and the descriptive character of the study, further investigations are necessary to examine a possible causal relationship.
压力被认为是导致睡眠磨牙症（SB）的一个潜在因素。本研究旨在调查特定的压力因素是否与 SB 活动相关。
69 名受试者，其中 48 名是 SB 患者，完成了三个评估不同压力参数和压力应对策略的德语问卷：短问卷识别压力因素（Kurzer Fragebogen zur Erfassung von Belastungen，KFB）、恢复和应变问卷（Erholungs-Belastungs-Fragebogen，EBF-24 A/3）和压力应对问卷（Stressverarbeitungsfragebogen-78，SVF-78）。SB 的诊断基于美国睡眠医学学会（AASM）的临床标准。SB 活动程度通过 Bruxcore-Bruxism-Monitoring-Device（BBMD，Bruxcore，Boston，USA）测量，佩戴五个连续晚上，并使用基于计算机的方法进行分析。非参数 Spearman 相关系数，rho，在心理测量数据和 BBMD 的像素评分测量的 SB 活动量之间进行计算。
发现“日常问题”（r = 0.461，p < 0.01）、“工作问题”（r = 0.293）、“疲劳”（r = 0.288）、“身体问题”（r = 0.288）和应对策略“逃避”（r = 0.295）（均 p < 0.05）之间存在显著相关性。
在本研究的限制范围内，可以表明 SB 活动水平较高的受试者在工作和日常生活中往往感到压力更大，这反过来可能影响他们的身体状况。这些受试者似乎也以消极的方式应对压力。然而，由于相关系数较低且研究具有描述性，需要进一步研究以检查可能的因果关系。
