气候变化直接和间接地影响着人类和社会。例如，阿拉斯加的变暖速度是全球平均速度的两倍，研究人员开始努力解决气候变化影响那里人民的各种相互关联的方式。随着气候变化导致阿拉斯加野火数量的增加，哮喘病例的数量也在增加，这是由于暴露于小颗粒物质所致。然而，目前尚不清楚野火产生的烟雾会在多远的距离内影响健康。在这项研究中，我们希望建立一个接近野火和哮喘的直接PM2.5measurements的位置之间的关系是不容易accomplished.MethodsIn这项研究中，我们研究了是否接近野火暴露与区域计数的成人哮喘，计算使用行为风险因素监测系统（BRFSS）的调查数据和美国人口普查数据。我们分配“热点”周围的人口中心与各种距离的野火在Alaska.ResultsWe发现，野火与哮喘的患病率，并在25英里的fires.ConclusionsThis研究强调了这样一个事实，即接近野火有可能作为一个简单的代理实际测量的野火烟雾，这对野火管理机构和必须解决与野火有关的健康问题的政策制定者，特别是在农村地区，具有重要意义。
BackgroundClimate change impacts humans and society both directly and indirectly. Alaska, for example, is warming twice as fast as the global mean, and researchers are starting to grapple with the varied and inter-connected ways in which climate change affects the people there. With the number of wildfires increasing in Alaska as a result of climate change, the number of asthma cases has increased, driven by exposure to small particulate matter. However, it is not clear how far away smoke from wildfires can affect health. In this study, we hope to establish a relationship between proximity to wildfires and asthma in locations where direct PM2.5measurement is not easily accomplished.MethodsIn this study, we examined whether proximity to wildfire exposure is associated with regional counts of adults with asthma, calculated using Behavioral Risk Factor Surveillance System (BRFSS) survey data and US Census data. We assigned “hotspots” around population centers with a range of various distances to wildfires in Alaska.ResultsWe found that wildfires are associated with asthma prevalence, and the association is strongest within 25 miles of fires.ConclusionsThis study highlights the fact that proximity to wildfires has potential as a simple proxy for actual measured wildfire smoke, which has important implications for wildfire management agencies and for policy makers who must address health issues associated with wildfires, especially in rural areas.
