Summary

A population-level study found a significant association between marine microplastic levels and the prevalence of heart and metabolic diseases like diabetes in U.S. coastal counties. While this does not prove microplastics directly cause these conditions, the correlation is notable and warrants further investigation at the individual level. The findings add to growing evidence that microplastic pollution may be linked to cardiovascular and metabolic health problems in humans.

Marine microplastic levels were significantly associated with the prevalence of cardiometabolic diseases in coastal counties. Comprehensive studies at an individual level are needed to further investigate the health impacts of microplastic pollution.
