This study was performed to investigate the relationship between the hospitalization rate for asthma and the ambient carbon monoxide (CO) by examining regional variation of the hospitalization rates for asthma in Korea and its factors. The hospital inpatient claims for asthma were acquired from the National Health Insurance database in 2015. A multivariate linear regression was performed with the hospitalization rate for asthma as a dependent variable. The annual ambient concentration of CO showed a negative association with the hospitalization rates for asthma while that of sulfur dioxide showed a positive association. The number of primary care physicians showed a negative association with the hospitalization rates for asthma while the number of beds in hospitals with less than 300 beds showed a positive association. The negative association of the ambient concentration of CO with the hospitalization rates for asthma showed results upon further investigation.
本研究旨在通过考察韩国哮喘住院率的地域差异及其影响因素，探讨哮喘住院率与环境一氧化碳（CO）之间的关系。2015 年，从国家健康保险数据库中获取哮喘住院患者的住院费用。以哮喘住院率为因变量进行多元线性回归分析。CO 的年环境浓度与哮喘住院率呈负相关，而二氧化硫的年环境浓度与哮喘住院率呈正相关。初级保健医生人数与哮喘住院率呈负相关，而少于 300 张床位的医院的床位数量与哮喘住院率呈正相关。进一步调查显示，CO 环境浓度与哮喘住院率呈负相关。
