American Indian communities suffer from a greater burden of diabetes and cardiovascular disease than other race/ethnicities in the United States. Individuals in many of these communities are often also exposed to higher concentrations of environmental toxicants via drinking water from unregulated private wells, proximity to legacy mining sites, or traditional diets. The Strong Heart Study is the largest study of cardiovascular disease among American Indians in the Southwest and the Northern Plains, ongoing since 1989. Key findings from the SHS have identified arsenic, cadmium and lead as critical determinants of cardiovascular disease and diabetes. Our work has sought to enhance this knowledge through the application of epigenetic aging and epigenetic biomarkers of exposure. In a study on epigenetic age acceleration, we found that Cd was associated with increased epigenetic age acceleration across all clocks and while mixtures analysis suggested nonlinear associations between Se and DunedinPACE, GrimAge, and PhenoAge acceleration. We also found that epigenetic biomarkers of lead were associated with cardiovascular disease mortality. We continue to expand this work with studies through the Superfund Research Program examining additional epigenetic biomarkers and microRNAs.
