The aim of this study was to evaluate the association between respiratory disorders and sleep bruxism, with an evaluation of demographic/socioeconomic factors and childhood stress as confounding variables.
A cross-sectional study was performed in the city of Diamantina, Brazil, with 448 randomly selected schoolchildren aged 8 to 11 years. The schoolchildren underwent an oral examination for the evaluation of bruxism. Parents/caregivers answered a questionnaire for the assessment of sleep bruxism; socioeconomic-demographic factors; and respiratory disorders, such as rhinitis, sinusitis, and bronchitis. The schoolchildren filled out the Children's Stress Scale. Poisson regression models were constructed separately for each respiratory disorder to determine prevalence ratios (PRs) and 95% confidence intervals (CIs).
Sleep bruxism was more prevalent among children with rhinitis (PR = 1.45; 95%CI 1.08-1.93; p = 0.012) and sinusitis (PR = 1.58; 95%CI 1.06-2.36; p = 0.023). No significant association was found between sleep bruxism and bronchitis. A greater frequency of sleep bruxism was found among children whose mothers had a higher level of schooling and those who reported stress in the resistance/exhaustion phase.
Rhinitis and sinusitis were associated with sleep bruxism. Moreover, sleep bruxism was more prevalent among children whose mothers had a higher level of schooling and those with higher degrees of stress.
本研究旨在评估呼吸系统疾病与睡眠磨牙症之间的关联，并将人口统计学/社会经济因素和童年压力作为混杂变量进行评估。
在巴西迪亚曼蒂纳市进行了一项横断面研究，随机选取了448名8至11岁的学童。这些学童接受了口腔检查以评估磨牙症情况。家长/照顾者回答了一份关于睡眠磨牙症、社会经济人口因素以及鼻炎、鼻窦炎和支气管炎等呼吸系统疾病的问卷。学童填写了儿童压力量表。针对每种呼吸系统疾病分别构建泊松回归模型，以确定患病率比值（PRs）和95%置信区间（CIs）。
鼻炎患儿（PR = 1.45；95%CI 1.08 - 1.93；p = 0.012）和鼻窦炎患儿（PR = 1.58；95%CI 1.06 - 2.36；p = 0.023）中睡眠磨牙症更为普遍。未发现睡眠磨牙症与支气管炎之间存在显著关联。母亲受教育程度较高的儿童以及在抵抗/疲惫阶段报告有压力的儿童中，睡眠磨牙症的发生率更高。
鼻炎和鼻窦炎与睡眠磨牙症有关。此外，母亲受教育程度较高的儿童以及压力较大的儿童中，睡眠磨牙症更为普遍。
