摘要

本研究旨在探讨广州市儿童呼吸道合胞病毒感染住院与气候、空气质量等因素的关系。我们收集了中国广州某三级医院2017年1月至2023年10月的RSV感染病例，收集了包括气温和相对湿度在内的每日气象数据以及包括PM2.5、PM10、SO2、CO、O3和NO2在内的空气污染物数据。最后，我们建立了分布滞后非线性模型（DLNM）来探讨RSV感染住院与气象因素和空气质量的关系。在收集到的1922例RSV感染报告中，96.31%的感染者为5岁以下儿童。我们的研究揭示了空气温度和相对湿度的降低与呼吸道合胞病毒感染引起的住院率上升之间的相关性。在空气质量方面，PM2.5、O3、NO2浓度高会增加RSV感染的风险，且相对风险随污染物浓度的增加而增加。此外，暴露于中等浓度PM2.5 (17-23 μg/m3) 3周也会增加RSV感染的风险。对于其他空气污染物，没有发现明显的规律。

Effects of climate and air quality on RSV infection hospitalization among children in Guangzhou from 2017 to 2023

This study aimed to explore the link between hospitalizations due to RSV infection and factors such as climate and air quality among children in Guangzhou. We included RSV infection cases from January 2017 to October 2023 in a tertiary hospital in Guangzhou, China, and then collected daily meteorological data including air temperature and relative humidity as well as air pollutant data including PM_2.5, PM₁₀, SO₂, CO, O₃, and NO₂. Finally, we established a distributional lag nonlinear model (DLNM) to investigate the association of hospitalization for RSV infection with meteorological factors and air quality. Of the 1922 reports of RSV infection collected, 96.31 % of the infections were under 5 years of age. Our study revealed a correlation between reductions in air temperature and relative humidity and the rise in hospitalizations due to RSV infection. With respect to air quality, high concentrations of PM_2.5, O₃, and NO₂ increase the risk of RSV infection, with the relative risk increasing with pollutant concentration. In addition, a 3-week exposure to moderate concentrations of PM_2.5 (17-23

μ g / m^{3}

) also increased the risk of RSV infection. For other air pollutants, there is no obvious pattern found.

期刊介绍： Atmospheric Environment has an open access mirror journal Atmospheric Environment: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. Atmospheric Environment is the international journal for scientists in different disciplines related to atmospheric composition and its impacts. The journal publishes scientific articles with atmospheric relevance of emissions and depositions of gaseous and particulate compounds, chemical processes and physical effects in the atmosphere, as well as impacts of the changing atmospheric composition on human health, air quality, climate change, and ecosystems.
