摘要

与结构性种族主义、剥夺公民权、贫困和其他持续的不平等来源相关的因素与脆弱性和暴露于环境危害有关。许多研究者利用与环境灾害易损性相关的社会、人口和环境因素来编制灾害易损性指数。在准备华盛顿州的气候变化健康风险评估时,我们比较了用于支持环境健康风险评估的六个指标的方法和结果。这些指数的产生因考虑的变量数量、计算复杂性和局部因果途径的暴露而异。这些指数的结果通常非常相似,特别是在脆弱性的最高十分位数,除了环境健康差距指数,它是唯一一个考虑危害暴露的指数。一些指数使用了隐藏因果关系的方法。那些暴露因果途径的研究限制了模型结构。结果表明,更简单的索引可能更适合用于决策支持工具,因为它们需要较少的数据更新和场景分析开销,而其他方法可能为索引生成提供更有用的框架。

A Comparison of Hazard Vulnerability Indexes for Washington State
Abstract Factors associated with structural racism, disenfranchisement, poverty, and other persistent sources of inequity are associated with vulnerability and exposure to environmental hazards. Social, demographic, and environmental factors associated with vulnerability to environmental hazards have been used by many researchers to produce indexes of hazard vulnerability. In preparation for a climate change health risk assessment for Washington state, we compared methods and results from six indexes designed to support environmental health risk assessment. Production of these indexes varies in the number of variables considered, calculation complexity, and exposure of local causal pathways. Results for these indexes are generally very similar, especially at the highest decile of vulnerability, the exception being the Environmental Health Disparities index, the only one to consider hazard exposure. Some indexes used methods that hide causal pathways. Those that exposed causal pathways limited model structure. Results indicate that simpler indexes may be more appropriate for use in decision support tools as they require less overhead for data updates and scenario analysis and that other methodologies may provide a more useful framework for index generation.
