A newly published study led by researchers at Mount Sinai has identified a significant association between exposure to per- and polyfluoroalkyl substances (PFAS) and an increased risk of developing type 2 diabetes. The findings, released in the peer-reviewed journal eBioMedicine, contribute to growing scientific concern over the long-term health impacts of these persistent environmental chemicals. PFAS, often referred to as “forever chemicals,” are synthetic compounds widely used in the production of nonstick cookware, waterproof clothing, stain-resistant textiles, and various industrial applications.
Known for their resistance to degradation, PFAS can remain in the environment and the human body for extended periods. Mount Sinai researchers examined whether elevated PFAS levels in blood samples were linked to a higher likelihood of developing type 2 diabetes over time. The study used a nested case-control design within BioMe, a large-scale, electronic health record-linked biobank that has compiled medical and demographic information from more than 70,000 patients who received care at Mount Sinai Hospital in New York since 2007.
Researchers selected 180 individuals who were recently diagnosed with type 2 diabetes and matched them with 180 control subjects without diabetes. Matching was based on age, sex, and ancestry to ensure a consistent comparison across key demographic variables. Blood samples from all 360 participants were analyzed to determine their PFAS exposure levels. The study found that individuals with higher concentrations of PFAS in their blood had a significantly increased risk of developing type 2 diabetes.
PFAS exposure shows strong correlation with diabetes onset
Specifically, each incremental increase in PFAS exposure range was associated with a 31 percent higher risk of diabetes onset, highlighting a strong and measurable correlation between chemical exposure and disease development. In addition to quantifying risk, the research explored potential biological mechanisms that could explain the observed relationship. The findings suggest that PFAS exposure may interfere with metabolic functions, particularly those involved in amino acid biosynthesis and drug metabolism.
These disruptions may impair the body’s ability to regulate blood glucose levels, contributing to the onset of insulin resistance and eventually leading to type 2 diabetes. The researchers emphasized that preventing exposure to PFAS should be a public health priority. They noted that while further research is needed to confirm causality and explore dose-response relationships, the evidence supports the importance of minimizing contact with these chemicals in both occupational and consumer settings.
This includes evaluating alternatives to PFAS-containing products and implementing stricter environmental and manufacturing controls. The study adds to a growing body of evidence linking PFAS to chronic health conditions, including hormonal disruption, immune system impairment, and certain cancers. With the global prevalence of type 2 diabetes continuing to rise, identifying environmental risk factors such as PFAS is essential for developing comprehensive prevention strategies and informing future regulatory policies. – By Content Syndication Services.
