Annual Change of the Prevalence of asthma is related to Air-pollution in Fukuoka Japan
Abstract
Background: It is reported that air pollution of suspended particulate material(SPM) and NO2 are related to the prevalence of the exacerbation and admission of asthma. However the relationship between the annual changes of the prevalence of asthma and concentrations of these pollutants is not so reported. It is reported the concentration of SPM is high in Fukuoka city Japan. The prevalence of asthma in this city is known to be high. However there has been no report about the relationship between these two items. Aim: we have studied the prevalence of asthma in the same 5 elementary school children in these 15 years in Fukuoka city. Fukuoka city studied the concentration of air-pollutants in these 15years, and open these data. We studied the relationship between the concentration of NO2 or SPM and the prevalence of asthma and allergic diseases. This study was approved by the ethical committee of Fukuoka Hospital. Results: There was the statistical significant correlationship between the concentration of NO2 or SPM and the prevalence of asthma in children.\u3000Concentration was evaluated as annual average of the 98% of average value per day, the year average, and the highest value of 1 hour value per day of these air pollutants. These tendency was higher in male children compared to female children. Discussion: Recent decrease of asthma prevalence in Japan might be related to the decreasing tendency of air pollutants concentration. Conclusion: The annual asthma prevalence was related to the concentration of air pollutant (NO2 and SPM, especially male children in Fukuoka city Japan. .
