Objectives: This study was conducted to identify the effects of PM10 and PM2.5 on hospital visits in the Incheon area over the period of 2016-2018.
Methods: We applied correlation analysis and Poisson regression to perform the analysis using cardiovascular disease and respiratory disease data from the National Health Insurance Service and the daily average PM10 and PM2.5 from the Korea Environment Corporation adjusting for time lag.
Results: When the daily average PM10 concentration increased by 10 μg/m3 , the number of cardiovascular disease patients were 1.002 times higher (95% CI [Confidence Interval]; 1.000-1004) in Ganghwa County. As the daily average PM2.5 concentration increased by 10 μg/m3 , the number of cardiovascular disease patients were 1.012 times higher (95% CI; 1.008-1.016) in Ganghwa County. As the daily average PM10 concentration increased by 10 μg/m3 , the respiratory disease patients were 1.003 times (95% CI; 1.002-1.004) higher in Gyeyang and Michuhol Counties. As the PM2.5 concentration increased by 10 μg/m3 , the respiratory disease patients were 1.003 times higher (95% CI; 1.002-1.005) in Bupyeong County.
Conclusions: In some parts of the Incheon area there was a correlation between the number of patients with respiratory and cardiovascular conditions and the concentration of PM10 and PM2.5.
