The prevalence of habitual snoring has been extensively explored in paediatric populations. Although exposure to cigarette smoke increases the risk of habitual snoring in a dose-dependent fashion, the potential contribution of air quality to habitual snoring remains unclear. 6000 questionnaires were distributed to 6- to 12-year-old children attending public schools in five distinct neighbourhoods within the city of Tehran, Iran, that were preselected based on air quality measures. Habitual snoring was defined as loud snoring ≥3 nights per week. Information regarding clinical and family-related habitual snoring risk factors was also obtained. Descriptive statistics followed by adjusted risk assessments were conducted. Among the 4322 (72%) completed datasets, the prevalence of habitual snoring was 11.6%. Partition of habitual snoring rates according to neighbourhood air quality characteristics revealed significantly higher habitual snoring frequencies among children residing in neighbourhoods with greatest pollution (24.5% and 12.1% in South and Central neighbourhoods versus 7.0% and 7.7% in North and East neighbourhoods, respectively). The regional variance in habitual snoring was primarily accounted for by an integrated measure of air quality, even after controlling for other risk factors. Environmental air quality emerges as a significant and potentially modifiable contributor to the risk for developing habitual snoring during childhood.

习惯性打鼾的患病率已在儿科人群中得到广泛探讨。尽管暴露于香烟烟雾会以剂量依赖的方式增加习惯性打鼾的风险,但空气质量对习惯性打鼾的潜在贡献仍不清楚。向伊朗德黑兰市五个不同社区的公立学校就读的6至12岁儿童分发了6000份问卷,这些问卷是根据空气质量指标预先选择的。习惯性打鼾被定义为每周大声打鼾 ≥ 3晚。还获得了有关临床和家庭相关的习惯性打鼾危险因素的信息。进行描述性统计,然后进行调整后的风险评估。在4322 (72%) 完成的数据集中,习惯性打鼾的患病率为11.6%。根据邻里空气质量特征对习惯性打鼾率的划分表明,居住在污染最大的社区中的儿童习惯性打鼾频率明显更高 (南部和中部分别为24.5% 和12.1%,北部和东部分别为7.0% 和7.7%)。即使在控制了其他危险因素之后,习惯性打鼾的区域差异也主要是通过对空气质量的综合衡量来解释的。环境空气质量成为导致儿童时期习惯性打鼾风险的重要且潜在的可改变因素。
