: To examine the potential impact of the World Trade Center (WTC) attacks on asthma-related emergency department visits (AREDV) in the New York City borough of the Bronx. We obtained daily nitrogen dioxide (NO), sulfur dioxide (SO) and ozone (O) values from the National Climatic Data Center's collection station in the Bronx from 1999 and 2002, a year before and after the WTC attacks. We compared daily AREDV and pollutant levels between 1999 and 2002 using the Wilcoxon signed rank sum test. We considered each season separately due to seasonal variations of AREDV and pollutants. We then used multiple linear regression models to assess the relationships between the changes in AREDV and the changes in pollutants from 1999 to 2002 in each season. : There were statistically significant increases from 1999 to 2002 in the daily NO in the summer. Significant increases for daily SO and O values from 1999 to 2002 occurred in all seasons. Significant increases occurred in daily AREDV values in the spring and fall. Multiple linear regression analyses showed that increases in the daily O values were significantly associated with increases in AREDV from 1999 to 2002 in the summer season. : We observed a possible association between the WTC attacks and significant increases in O and SO for all seasons, and NO for the summer. AREDV significantly increased following the WTC attacks. Increases in daily O values were significantly associated with increases in AREDV in the summer season.
为研究世界贸易中心（WTC）袭击事件对纽约市布朗克斯区哮喘相关急诊就诊量（AREDV）的潜在影响。我们获取了1999年至2002年（WTC袭击事件发生前一年和后一年）位于布朗克斯区的国家气候数据中心采集站的每日二氧化氮（NO）、二氧化硫（SO）和臭氧（O）值。我们使用威尔科克森符号秩和检验比较了1999年和2002年的每日AREDV和污染物水平。由于AREDV和污染物存在季节性变化，我们对每个季节分别进行了考虑。然后，我们使用多元线性回归模型评估了每个季节1999年至2002年AREDV变化与污染物变化之间的关系。1999年至2002年夏季每日NO有统计学意义的增加。1999年至2002年所有季节每日SO和O值均有显著增加。春季和秋季每日AREDV值有显著增加。多元线性回归分析表明，夏季每日O值的增加与1999年至2002年AREDV的增加显著相关。我们观察到WTC袭击事件与所有季节的O和SO以及夏季的NO显著增加之间可能存在关联。WTC袭击事件后AREDV显著增加。夏季每日O值的增加与AREDV的增加显著相关。
