Per- and polyfluoroalkyl substances (PFAS), widely termed “forever chemicals” due to their environmental persistence and bioaccumulation, are now under scrutiny for their impact on skeletal development. While their presence in non-stick cookware and waterproof textiles is well-documented, a recent study in the Journal of the Endocrine Society suggests these compounds may actively undermine bone mineral density during critical growth windows in early life.
The study
Researchers analysed blood samples from 218 adolescents who were part of a long term pregnancy and birth cohort. Researchers measured PFAS levels at multiple points, including at birth and at ages 3, 8, and 12. Bone density was then assessed when participants reached age 12.
Key findings
PFOA and Bone density The results revealed that adolescents with higher levels of perfluorooctanoic acid (PFOA), one of the most widely studied PFAS compounds, tended to have lower bone density in the forearm.
Window of exposure For other PFAS compounds, the relationship with bone density depended on when the exposure occurred. The pattern suggests that certain stages of childhood development may be more sensitive to these chemicals.
Gender predilection The link between PFAS and reduced bone density was also stronger in females in comparison to the males.
These findings add to growing evidence that PFAS exposure during early life may carry long-term health consequences, underscoring the importance of efforts to reduce contamination in drinking water and consumer products.
With the presence of forever chemicals in almost every sphere of our life, the question that remains; is the escape even possible?
