Abstract

Evidence regarding the cognitive effects of air pollution is inconsistent. This study aimed to quantitatively analyze the relationship between air pollutants and cognitive abilities using the Mini-Mental State Examination (MMSE). We systematically searched for studies published until July 1, 2023, and assessed heterogeneity with Cochran's Q test and I² statistics, while publication bias was evaluated using Funnel plots and Egger's test. Out of 380 studies, 17 were included in the meta-analysis. Results demonstrated significant relationship among long-term exposure to PM_2.5, O₃, and cognitive decline. The pooled RR of cognitive impairment per 10μg/m³ increase were 1.17 for PM_2.5 and 1.07 for PM₁₀. Furthermore, there was a significant association between cognitive decline and long-term exposure to PM_2.5 (β = -0.30; I² = 95.30%) and PM₁₀ (β = -0.15; I² = 87.50%). Our research suggests that long-term exposure to air pollution, especially PM_2.5, is a risk factor for cognitive impairment.

基于最低精神状态检查的空气污染暴露与认知功能：系统回顾与荟萃分析。

有关空气污染对认知能力影响的证据并不一致。本研究旨在使用迷你精神状态检查（MMSE）定量分析空气污染物与认知能力之间的关系。我们系统地检索了 2023 年 7 月 1 日前发表的研究，并使用 Cochran's Q 检验和 I² 统计量评估了异质性，同时使用 Funnel 图和 Egger 检验评估了发表偏倚。在 380 项研究中，有 17 项纳入了荟萃分析。结果表明，长期暴露于 PM2.5、O3 与认知能力下降之间存在明显关系。PM2.5和PM10每增加10微克/立方米，认知障碍的总RR分别为1.17和1.07。此外，认知能力下降与长期暴露于PM2.5（β = -0.30；I2 = 95.30%）和PM10（β = -0.15；I2 = 87.50%）之间存在明显关联。我们的研究表明，长期暴露于空气污染，尤其是 PM2.5，是导致认知障碍的一个风险因素。

期刊介绍： International Journal of Environmental Health Research ( IJEHR ) is devoted to the rapid publication of research in environmental health, acting as a link between the diverse research communities and practitioners in environmental health. Published articles encompass original research papers, technical notes and review articles. IJEHR publishes articles on all aspects of the interaction between the environment and human health. This interaction can broadly be divided into three areas: the natural environment and health – health implications and monitoring of air, water and soil pollutants and pollution and health improvements and air, water and soil quality standards; the built environment and health – occupational health and safety, exposure limits, monitoring and control of pollutants in the workplace, and standards of health; and communicable diseases – disease spread, control and prevention, food hygiene and control, and health aspects of rodents and insects. IJEHR is published in association with the International Federation of Environmental Health and includes news from the Federation of international meetings, courses and environmental health issues.
