Abstract

Background: There is little information about air pollution and epilepsy attacks. The aim of this study was to investigate the relation between air pollution and epilepsy admission in Kerman, Iran.Methods: This was an ecological study, in which the concentrations of ambient air pollutants and meteorological data were inquired from the Kerman Environmental Protection Agency and the Kerman Meteorology Organization respectively, and epilepsy admission data were obtained from Kerman’s Shafa hospital Epilepsy Registry. Generalized Additive Models (GAM) with lags up to 7 days were used for estimating the Relative Risks (RR).Results: During 2008 until 2020, 894 epilepsy admission occurred in Kerman which 498 (55.7%) were male. The strongest relation between epilepsy admission was seen in the over 59 years group for CO in lag 0 (RR = 2.1455, 95% CI: 1.5823–2.9091), for NO2 in lag 0 (RR =1.0409, 95% CI: 1.0282–1.0537), and for PM2.5 in lag 5 (RR =1.0157, 95% CI: 1.0062–1.0252). Also for PM10 in the under 18 year's group in lag 2 (RR =1.0064, 95% CI: 1.0029–1.0098), for O3 in lag 0 (RR =0.9671, 95% CI: 0.9581–0.9761) and for SO2 in lag 5 (RR = 0.9937, 95% CI: 0.9891–0.9983).Conclusion: The findings of this study showed that CO, NO2, PM2.5, and PM10 air pollutants might be risk factors for epilepsy admission in Kerman.

伊朗克尔曼的空气污染与癫痫住院

背景：关于空气污染和癫痫发作的信息很少。本研究旨在调查伊朗克尔曼的空气污染与癫痫入院之间的关系。方法：这是一项生态学研究，分别向克尔曼环境保护局和克尔曼气象组织询问了环境空气污染物浓度和气象数据，癫痫入院数据来自Kerman’s Shafa医院癫痫登记处。结果：2008年至2020年，克尔曼共有894例癫痫患者入院，其中498例（55.7%）为男性。在59岁以上组中，滞后0的CO（RR=2.1455，95%CI:1.5823–2.9091）、滞后0的NO2（RR=1.0409，95%CI:1.0282–1.0537）和滞后5的PM2.5（RR=1.0157，95%CI:1.0062–1.0252）与癫痫入院之间的关系最强。同样，滞后2的18岁以下组的PM10（RR=1.064，95%CI:11.0029–1.0098），O3在滞后0（RR=0.9671，95%CI:0.9581–0.9761）和SO2在滞后5（RR=0.9937，95%CI:0.09891–0.9983）。结论：本研究结果表明，CO、NO2、PM2.5和PM10空气污染物可能是克尔曼癫痫入院的危险因素。
