Assessing PFAS Exposure for Better Health

The goal of this observational study is to determine whether a personalized PFAS (per- and polyfluoroalkyl substances) blood test and educational report-back can improve environmental health literacy (EHL), empower exposure reduction behaviors, and promote cardiovascular wellness among rural adults. The main questions it aims to answer are: Does receiving a personalized PFAS test result and educational report-back increase environmental health literacy among rural participants and healthcare providers? Does increased EHL lead to greater readiness and actions to reduce PFAS exposure and improve wellness outcomes (e.g., reduced stress, improved sleep, increased sense of control) Researchers will compare changes from pre- to post-intervention among participants who receive the personalized PFAS report-back to see if there are measurable improvements in knowledge, behavior, and wellbeing. Participants will: Provide a mail-in blood spot sample for PFAS testing using a validated laboratory method (Relentless Health). Complete online surveys before and after receiving results to assess PFAS knowledge, exposure behaviors, and wellness outcomes. Receive a personalized PFAS report-back summarizing individual results, exposure sources, and tailored strategies for exposure reduction. Participate in focus groups or interviews (subset only) to provide feedback on report clarity, usability, and communication preferences. This study focuses on rural adult residents of Nevada, including underserved populations who may face limited access to PFAS testing or environmental health education. Insights from this Phase I project will guide a future randomized controlled trial evaluating the intervention's broader impact on cardiovascular health and rural health equity.
