To assess the frequency of reported masticatory muscles activity during wakefulness (i.e., awake bruxism [AB]), levels of anxiety, depression, stress, and the oral health-related quality of life (OHRQoL) in college preparatory students.
Sixty-nine college preparatory students participated in the study. AB was evaluated by the Oral Behaviors Checklist (OBC) and a smartphone-based ecological momentary assessment (EMA; [Bruxapp®]). Anxiety and depression were measured by the Hospital Anxiety and Depression Scale, stress was evaluated by the Perceived Stress Scale, and OHRQoL was obtained by The Oral Health Impact Profile-14. Data were analyzed by Pearson's correlation coefficient (α = 0.05).
The average EMA-reported frequency of AB behaviors was 38.4%. Significant correlations were found between AB and the OBC, anxiety, depression, stress, and OHRQoL (p < 0.001).
College preparatory students demonstrated moderate frequency of AB, which was significantly correlated with psychosocial factors.
评估大学预科学生清醒时咀嚼肌活动（即清醒性磨牙症[AB]）的报告频率、焦虑水平、抑郁水平、压力水平以及口腔健康相关生活质量（OHRQoL）。
69名大学预科学生参与了本研究。通过口腔行为检查表（OBC）和基于智能手机的生态瞬时评估（EMA；[Bruxapp®]）对AB进行评估。采用医院焦虑抑郁量表测量焦虑和抑郁，通过感知压力量表评估压力，并通过口腔健康影响程度量表-14获取OHRQoL。数据采用Pearson相关系数进行分析（α = 0.05）。
EMA报告的AB行为平均频率为38.4%。发现AB与OBC、焦虑、抑郁、压力和OHRQoL之间存在显著相关性（p < 0.001）。
大学预科学生表现出中等频率的AB，且与心理社会因素显著相关。
