摘要

空气污染,尤其是直径小于 2.5 微米的细颗粒物(PM2.5)会导致呼吸系统和心血管疾病,并在全球范围内构成重大公共健康风险。本研究评估了 PM2.5 对心血管和呼吸系统疾病入院率的短期影响,并根据地区特征进行了额外分析,以确定易感人群。本研究分析了韩国 249 个社区在 2006 年至 2021 年期间的数据。每天因心血管和呼吸系统疾病入院的数据来自国民健康保险服务。PM2.5 浓度数据来自空气质量模型。我们还收集了有关地区特征的其他数据,包括地区贫困指数、老年居民比例、教育水平和绿化水平。我们使用病例时间序列分析法评估了 PM2.5 浓度与心血管疾病和呼吸系统疾病入院人数之间的关联,并通过分层分析探讨了区域特征对效果的影响。每天因心血管疾病和呼吸系统疾病入院的平均人数分别为 5.68 ± 5.46 和 6.46 ± 8.03。PM2.5 的平均浓度为 23.58 ± 13.66 μg/m3。PM2.5日浓度每增加10微克/立方米,心血管和呼吸系统住院率分别增加0.94%(95% CI:0.84%,1.04%)和1.43%(95% CI:1.34%,1.52%)。地区特征分析表明,在贫困程度较低和绿化程度较低的地区,入院风险较高。这项研究强调了 PM2.5 对韩国社区呼吸道和心血管疾病入院率的重大短期健康影响。研究结果强调了地区和人口因素在调节这些影响方面的关键作用,指出社会经济地区、人口年龄结构、较低的教育水平和低绿化率是关键的脆弱性因素。

Spatial associations of daily PM2.5 concentration with cardiovascular and pulmonary morbidity in Korea
Air pollution, particularly fine particulate matter less than 2.5 μm in diameter (PM2.5), contributes to respiratory and cardiovascular diseases and poses significant public health risks worldwide. This study evaluated the short-term effects of PM2.5 on hospital admissions for cardiovascular and respiratory diseases, with additional analyses to identify vulnerable populations based on regional characteristics.
The present study analyzed data from 249 Korean communities between 2006 and 2021. Data on daily hospital admissions for cardiovascular and respiratory diseases were obtained from the National Health Insurance Service. Data on PM2.5 concentrations were sourced from air quality modeling. Additional data on regional characteristics, including the regional deprivation index, proportion of elderly residents, education levels, and greenness levels, were also collected. We used case time series analysis to assess the associations between PM2.5 concentrations and hospital admissions for cardiovascular and respiratory diseases and explored effect modification by regional characteristics with stratified analyses.
The mean numbers of daily cardiovascular admissions and respiratory admissions were 5.68 ± 5.46 and 6.46 ± 8.03, respectively. The mean PM2.5 concentrations were 23.58 ± 13.66 μg/m3. A10 μg/m³ increment in daily PM2.5 concentration was associated with increase of cardiovascular and respiratory hospitalization by 0.94% (95% CI: 0.84%, 1.04%) and 1.43% (95% CI: 1.34%, 1.52%), respectively. Regional characteristics analysis showed significant disparities, with higher risks for hospital admissions in areas with lower deprivation and low greenness.
This study highlights the significant short-term health impacts of PM2.5 on respiratory and cardiovascular hospital admissions in Korean communities. The findings underscore the critical role of regional and demographic factors in modulating these effects, identifying socio-economic areas, age structure of the population, lower education levels, and low greenness as key vulnerability factors.
