目的睡眠磨牙症是一种严重危害口腔健康的主要睡眠障碍，被认为是一种多因素疾病。吸烟会引起睡眠磨牙症，这也会对睡眠质量产生不利影响。本研究的目的是阐明睡眠磨牙症、睡眠质量和二手烟暴露之间的关系。方法为了评估睡眠磨牙症、睡眠质量和二手烟暴露的患病率，我们对日本大学生进行了口腔检查和自我报告问卷调查。使用日本版匹兹堡睡眠质量指数（PSQI）和第三版睡眠障碍国际分类（ICSD-3）对睡眠磨牙症和质量进行筛查。纳入标准为年龄在 18 至 19 岁之间的成年人、不吸烟者和不饮酒者。排除标准是未能完整填写问卷。结果我们总共分析了 1781 名日本年轻人。接触过二手烟的年轻女性的睡眠质量比没有接触过的女性要差 (p = 0.019)。睡眠质量较差的年轻成年女性比睡眠质量较好的女性更容易出现睡眠磨牙症 (p = 0.034)。使用结构方程模型，确定了年轻成年女性的二手烟暴露与睡眠质量差（标准化系数，0.153；p = 0.008）以及睡眠磨牙症和睡眠质量差（标准化系数，0.187；p = 0.022）之间的直接关联。然而，在年轻成年男性中没有发现关联。 结论 日本年轻成年女性的睡眠质量差，导致二手烟暴露与睡眠磨牙症间接相关。
ObjectiveSleep bruxism, a major sleep disorder that causes serious harm to oral health, is considered a multifactorial disease. Sleep bruxism can be induced by smoking, which also adversely affects sleep quality. The objective of present study was to clarify the associations between sleep bruxism, sleep quality, and exposure to secondhand smoke (SHS).MethodsTo assess the prevalence of sleep bruxism, sleep quality, and SHS exposure, we conducted oral examinations and self-report questionnaires on university students in Japan. Sleep bruxism and quality were screened using the Japanese version of the Pittsburgh Sleep Quality Index (PSQI) and the third edition of the International Classification of Sleep Disorders (ICSD-3). The inclusion criteria were adults aged between 18 and 19 years, non-smokers and non-alcohol drinkers. The exclusion criteria was failing to complete the questionnaire in full.ResultsWe analyzed a total of 1781 Japanese young adults. Young adult females who had been exposed to SHS had worse sleep quality (p = 0.019) than those who had not. Young adult female with worse sleep quality showed a higher prevalence of sleep bruxism (p = 0.034) than those with better sleep quality. Using structural equation modeling, direct associations were identified between SHS exposure and poor sleep quality (standardized coefficients, 0.153; p = 0.008) and between sleep bruxism and poor sleep quality (standardized coefficients, 0.187; p = 0.022) in young adult females. However, no association was found among young adult males.ConclusionSHS exposure is indirectly associated with sleep bruxism through poor sleep quality in Japanese young adult females.
