Introduction

Climate change is leading to increasingly severe wildfires across the United States. Over the past several years, these events have led to extreme, persistent smoke events in several urban areas across the western U.S. However, the health impacts of smoke events on urban communities are not well understood. Impacts to physical activity, including active transportation, may be a useful proxy to understand physical and mental health effects of these events. We aimed to examine the impact of wildfire smoke events, determined by fine particulate matter concentrations and administrative reporting, on physical activity, measured by pedestrian and bicycle counts at eight city counters in Seattle, WA, USA.

Methods

We assessed for differences in daily average bicycle and pedestrian counts between pre-, during- and post-wildfire smoke periods for two wildfire smoke events in Seattle in the summers of 2017 and 2018.

Results

The 2018 wildfire smoke event significantly decreased daily average bicycle counts by 14.6–36.0% across the 8 counters, and 31.7%–45.2% across the two pedestrian counters. There were no significant changes in use during the 2017 event, with the exception of a significant decrease in counts at one pedestrian counter.

Conclusions

Urban physical activity and active transportation may be significantly impacted by future wildfire smoke events, with cascading public health consequences. Differences in impacts across the 2017 and 2018 events may be related to increased intensity of smoke, and/or to enhanced public health messaging by state and local agencies. Additional research is needed to better understand the impact of wildfire smoke on physical activity in urban communities, and to assess and inform public health risk communication campaigns to change behavior during these events.

华盛顿州西雅图市野火烟雾事件对城市自行车和行人活动的影响

介绍

气候变化正在导致全美国范围内越来越严重的野火。在过去的几年中,这些事件在美国西部的多个城市地区导致了极端的持续性烟雾事件。但是,人们对烟雾事件对城市社区的健康影响知之甚少。对身体活动的影响,包括主动运输,可能是了解这些事件对身体和心理健康的影响的有用替代。我们旨在检查由细颗粒物浓度和行政报告确定的野火烟雾事件对体育活动的影响,该运动由美国华盛顿州西雅图市的八个城市柜台的行人和自行车计数来衡量。

方法

我们评估了2017年和2018年夏季在西雅图发生的两次野火烟雾事件的野火前后,期间和之后的每日平均自行车和行人计数之间的差异。

结果

2018年的野火烟雾事件在8个柜台中使每日平均自行车计数显着减少了14.6–36.0%,在两个行人柜台中显着减少了31.7%–45.2%。在2017年的活动中,除了一个行人柜台的计数显着减少之外,使用方面没有任何重大变化。

结论

未来的野火烟雾事件可能会严重影响城市的体育活动和积极的交通,并给公共健康带来一系列后果。2017年和2018年事件的影响差异可能与吸烟强度增加和/或州和地方机构加强公共卫生信息传递有关。需要进行更多的研究,以更好地了解野火烟雾对城市社区体育活动的影响,并评估和告知公众健康风险交流活动,以改变这些事件期间的行为。
