Anxiety disorders are among the most common mental health concerns today. While numerous factors are known to affect anxiety disorders, the ways in which environmental factors aggravate or mitigate anxiety are not fully understood.
Baidu is the most widely used search engine in China, and a large amount of data on internet behavior indicates that anxiety is a growing concern. We reviewed the annual Baidu Indices of anxiety-related keywords for cities in China from 2013 to 2018 and constructed anxiety indices. We then employed a two-way fixed effect (FE) model to analyze the relationship between PM exposure and anxiety at the prefectural level.
The results indicated that there was a significant positive association between PM and anxiety index. The anxiety index increased by 0.1565258 for every unit increase in the PM level (P < 0.05), which suggested that current PM levels in China pose a considerable risk to mental health.
The enormous impact of PM exposure indicates that the macroscopic environment can shape individual mentality and social behavior, and that it can be extremely destructive in terms of societal mindset.
焦虑症是当今最常见的心理健康问题之一。尽管有许多已知的因素会影响焦虑症，但环境因素加剧或减轻焦虑的方式仍未被完全理解。
百度是中国使用最广泛的搜索引擎，大量的互联网行为数据表明焦虑是一个日益严重的问题。我们回顾了 2013 年至 2018 年中国城市的年度与焦虑相关的百度指数关键词，并构建了焦虑指数。然后，我们采用双向固定效应（FE）模型来分析地级市层面 PM 暴露与焦虑之间的关系。
结果表明，PM 与焦虑指数之间存在显著的正相关关系。PM 水平每增加一个单位，焦虑指数增加 0.1565258（P<0.05），这表明中国目前的 PM 水平对心理健康构成了相当大的风险。
PM 暴露的巨大影响表明宏观环境可以塑造个体的心态和社会行为，并且它可能对社会心态具有极强的破坏性。
