Environmental health agencies are critical sources of information for communities affected by chemical contamination. Impacted residents and their healthcare providers often turn to federal and state agency webpages, fact sheets, and other documents to weigh exposure risks and interventions.
This commentary briefly reviews scientific evidence concerning per- and polyfluoroalkyl substances (PFAS) for health outcomes that concern members of affected communities and that have compelling or substantial yet differing degree of scientific evidence. It then features official documents in their own language to illustrate communication gaps, as well as divergence from scientific evidence and from best health communication practice. We found official health communications mostly do not distinguish between the needs of heavily contaminated communities characterized by high body burdens and the larger population with ubiquitous but substantially smaller exposures. Most health communications do not distinguish levels of evidence for health outcomes and overemphasize uncertainty, dismissing legitimate reasons for concern in affected communities. Critically, few emphasize helpful approaches to interventions. We also provide examples that can be templates for improvement.
Immediate action should be undertaken to review and improve official health communications intended to inform the public and health providers about the risks of PFAS exposure and guide community and medical decisions.
环境健康机构是受化学污染影响社区的重要信息来源。受影响的居民及其医疗保健提供者通常会转向联邦和州机构的网页、情况说明书和其他文件,以权衡暴露风险和干预措施。
本评论简要回顾了有关对受影响社区成员健康结果有影响的全氟和多氟烷基物质(PFAS)的科学证据,这些健康结果具有令人信服或实质性但程度不同的科学证据。然后,它以原文形式展示了官方文件,以说明沟通差距,以及与科学证据和最佳健康沟通实践的背离。我们发现,官方卫生通讯大多没有区分身体负担沉重的高度污染社区的需求与暴露程度普遍较高但明显较小的更大人群的需求。大多数卫生通讯没有区分健康结果的证据水平,过分强调不确定性,无视受影响社区中合理的担忧理由。至关重要的是,很少有人强调干预的有益方法。我们还提供了可以作为改进模板的示例。
应立即采取行动,审查和改进旨在告知公众和卫生提供者有关 PFAS 暴露风险并指导社区和医疗决策的官方卫生通讯。
