Although there are many findings about the effects of fine particulate matter (PM) and sleep deprivation on health respectively, the association between PM and chronic sleep deprivation has rarely been investigated. Thus, we aimed to investigate this association using a nationwide survey in South Korea.
We examined the association between long-term exposure to PM and chronic sleep deprivation using a national cross-sectional health survey covering the entire 226 districts in inland South Korea from 2008 to 2018, with a machine learning-based national air pollution prediction model with 1 km spatial resolution.
Chronic sleep deprivation was positively associated with PM in the total population (odds ratio (OR): 1.09, 95% confidence interval (CI): 1.05-1.13) and sub-population (low, middle, high population density areas with OR: 1.127, 1.09, and 1.059, respectively). The association was consistently observed in both sexes (males with OR: 1.09, females with OR: 1.09)) and was more pronounced in the elderly population (OR: 1.12) than in the middle-aged (OR: 1.07) and young (OR: 1.09) populations.
Our results are consistent with the hypothesis regarding the relationship between long-term PM exposure and chronic sleep deprivation, and the study provides quantitative evidence for public health interventions to improve air quality that can affect chronic sleep conditions.
尽管已有大量研究分别探讨了细颗粒物（PM）和睡眠剥夺对健康的影响，但 PM 与慢性睡眠剥夺之间的关联却鲜有研究。因此，我们旨在通过在韩国进行的一项全国性调查来研究这种关联。
我们利用一个基于机器学习的全国空气污染预测模型，该模型具有 1km 的空间分辨率，调查了 2008 年至 2018 年韩国内陆 226 个地区的全国性横断面健康调查中 PM 长期暴露与慢性睡眠剥夺之间的关联。
在总人口（比值比（OR）：1.09，95%置信区间（CI）：1.05-1.13）和子人群（低、中、高人口密度地区，OR 分别为 1.127、1.09 和 1.059）中，慢性睡眠剥夺与 PM 呈正相关。这种关联在两性（男性 OR：1.09，女性 OR：1.09）中均得到一致观察，在老年人群（OR：1.12）中比中年人群（OR：1.07）和青年人群（OR：1.09）更为明显。
我们的结果与长期 PM 暴露与慢性睡眠剥夺之间关系的假设一致，并为改善空气质量的公共卫生干预措施提供了定量证据，这些措施可能会影响慢性睡眠状况。
