OBJECTIVE This cross-sectional clinical study evaluated the associations between sociodemographic, occupational, clinical conditions, psychological and sleep quality variables on definite sleep bruxism (SB). METHODS All records obtained from adults (aged 20-60 years) and the elderly (aged >60 years) who had undergone polysomnography (PSG) at a private medical outpatients' clinic from July 2017 to February 2018 were reviewed. Data from a questionnaire, based on the criteria of the American Academy of Sleep Medicine (AASM), were also gathered. Definite SB data pattern distribution was analyzed, and multivariate Poisson regression with robust variance was used to assess the associations between definite SB diagnosis, determined via PSG recordings, and the independent variables. A significance level of 5% was adopted. RESULTS A total of 240 individuals were included in the study and the SB prevalence was 7.08% (n = 17). The adjusted Poisson regression analysis revealed association between definitive SB and individuals with respiratory allergy (PR = 3.63; 95% CI:1.01-13; P = 0.047) and restless sleep (PR = 2.97; 95% CI:1.04-8.50; P = 0.042). CONCLUSION This study found associations between definite SB and clinical conditions (respiratory allergy) and sleep behavior (restless sleep). Knowledge regarding factors associated with definite SB can contribute to decision making in the clinical setting and management strategies involving a multidisciplinary approach.

呼吸道过敏和不安定睡眠对明确睡眠磨牙症的影响：一项横断面临床研究。

目的这项横断面临床研究评估了社会人口统计学，职业，临床状况，心理和睡眠质量变量与确定性睡眠磨牙症（SB）之间的关系。方法对2017年7月至2018年2月在私人门诊接受多导睡眠图（PSG）的成年人（20-60岁）和老年人（60岁以上）的所有记录进行回顾。还根据美国睡眠医学学会（AASM）的标准从问卷中收集了数据。分析了确定的SB数据模式分布，并使用具有鲁棒方差的多元Poisson回归来评估通过PSG记录确定的确定的SB诊断与独立变量之间的关联。显着性水平为5％。结果研究共纳入240个人，SB患病率为7.08％（n = 17）。调整后的Poisson回归分析显示，确定性SB与患有呼吸道过敏（PR = 3.63; 95％CI：1.01-13; P = 0.047）和不安定睡眠（PR = 2.97; 95％CI：1.04-8.50; P = 0.042）。结论本研究发现了确定的SB与临床状况（呼吸道过敏）和睡眠行为（不安定睡眠）之间的关联。有关与确定性SB相关的因素的知识可以有助于涉及多学科方法的临床环境和管理策略中的决策。调整后的Poisson回归分析显示，确定性SB与患有呼吸道过敏（PR = 3.63; 95％CI：1.01-13; P = 0.047）和不安定睡眠（PR = 2.97; 95％CI：1.04-8.50; P = 0.042）。结论本研究发现了确定的SB与临床状况（呼吸道过敏）和睡眠行为（不安定睡眠）之间的关联。有关与确定性SB相关的因素的知识可以有助于涉及多学科方法的临床环境和管理策略中的决策。调整后的Poisson回归分析显示，确定性SB与患有呼吸道过敏（PR = 3.63; 95％CI：1.01-13; P = 0.047）和不安定睡眠（PR = 2.97; 95％CI：1.04-8.50; P = 0.042）。结论本研究发现了确定的SB与临床状况（呼吸道过敏）和睡眠行为（不安定睡眠）之间的关联。有关与确定性SB相关的因素的知识可以有助于涉及多学科方法的临床环境和管理策略中的决策。
