在许多国家，哮喘加重的发病率一直在上升。环境因素可能在这一趋势中发挥重要作用。我们的目的是调查天气条件和空气污染与哮喘显著加重的关系。方法：通过2005年1月1日至12月31日东京都消防局的急救记录，收集每日哮喘救护车就诊次数。我们还收集了同一时期东京的每日空气污染水平和气象数据。气象资料包括最低气温、最高气压、最高相对湿度和降水。测量的空气污染物包括二氧化硫、一氧化二氮、氮氧化物、悬浮颗粒物和一氧化碳。我们使用多变量调整自回归综合移动平均模型进行了时间序列分析。该分析分别在成人和儿童中进行(
Introduction: The incidence of asthma exacerbation has been increasing in many countries. Environmental factors may play an important role in this trend. We aimed to investigate the relationship of weather conditions and air pollution to significant exacerbation of asthma.Methods: The daily number of emergency department (ED) visits by ambulance for asthma was collected through records of the Tokyo Fire Department from January 1 to December 31, 2005. We also collected daily air pollution levels and meteorological data for Tokyo during the same period. Meteorological data included minimum temperature, maximum barometric pressure, maximum relative humidity, and precipitation. Measured air pollutants included sulfur dioxide, nitrogen monoxide, nitrogen oxides, suspended particulate matter, and carbon monoxide. We performed a time series analysis using multivariable-adjusted autoregressive integrated moving average model. The analysis was conducted separately among adults and among children (
