The purpose of this study was to assess health-related responses to wildfire smoke on social media. We examined whether seasonal wildfire smoke is an active topic on Twitter, the correlation between fine particulate matter (PM ) and Twitter search terms, and dimensions of community-level expression to wildfire smoke through tweets.
Search terms were identified using a conceptual model developed and refined by healthcare providers and public health experts. Wildfire-related tweets were downloaded from Twitter users in Spokane, Washington during the 2017 and 2018 wildfire seasons. PM data were correlated with the search terms. A subset of tweets was deductively and then inductively coded to identify perceptions and behavioral responses to wildfire smoke.
Seasonal wildfire smoke is an active topic on Twitter. The term "smoke" was strongly correlated with poor air quality and "unhealthy" was moderately correlated. Deductive analyses revealed a multidimensional response to wildfire smoke. Inductive analysis identified new areas of concern, such as pet and animal health.
Social media is a lens through which public health professionals can assess and respond to local community needs. Findings will be used to broaden the conceptual model, enhance ongoing surveillance of community-identified health risks, and communicate protective actions.
本研究旨在评估社交媒体上与野火烟雾相关的健康反应。我们考察了季节性野火烟雾是否是 Twitter 上的一个活跃话题、细颗粒物 (PM ) 与 Twitter 搜索词之间的相关性，以及通过推文表达的社区层面对野火烟雾的维度。
使用医疗保健提供者和公共卫生专家制定和完善的概念模型来确定搜索词。在 2017 年和 2018 年野火季节，从华盛顿州斯波坎的 Twitter 用户那里下载与野火相关的推文。将 PM 数据与搜索词相关联。从推文中提取出一个子集，然后进行演绎和归纳编码，以确定对野火烟雾的看法和行为反应。
季节性野火烟雾是 Twitter 上的一个活跃话题。“烟雾”一词与空气质量差呈强相关，“不健康”呈中度相关。演绎分析揭示了对野火烟雾的多维反应。归纳分析确定了新的关注点，如宠物和动物健康。
社交媒体是公共卫生专业人员评估和应对当地社区需求的一个视角。研究结果将用于扩展概念模型，加强对社区确定的健康风险的持续监测，并传达保护措施。
