'Forever Chemicals' May Be Weakening The Bones of Children, Study Warns
A new study warns that 'forever chemicals,' or PFAS, may be weakening children's bones, adding to growing health concerns. Researchers analyzed health data from 218 children, finding an association between perfluorooctanoic acid (PFOA) and lower forearm bone density at age 12, with a stronger link observed in females. These findings suggest early-life PFAS exposure could have long-term health consequences, potentially increasing bone fracture risk by 30%. Experts emphasize the need to reduce contamination in drinking water and consumer products to protect children's developing skeletons.
A recent study has raised alarms about the impact of 'forever chemicals,' or per- and polyfluoroalkyl substances (PFAS), on children's bone health, linking certain types to weakened bones. PFAS are notorious for their environmental persistence and widespread use in industries, making them nearly impossible to avoid. Researchers from the US and Canada conducted an observational study, analyzing health data and blood PFAS levels (including PFHxS, PFOS, PFOA, and PFNA) of 218 children, cross-referencing these with bone density measurements at different ages.The study specifically found an association between PFOA levels and lower forearm bone density in children at age 12. The researchers also noted that the association with bone density varied depending on exposure time, suggesting age is a crucial factor. Epidemiologist Jessie Buckley from the University of North Carolina highlighted that these findings reinforce existing evidence of early-life PFAS exposure leading to long-term health issues, emphasizing the need to reduce contamination. A notable discovery was the stronger link between higher PFAS levels and lower bone density in females, a finding slated for future investigation. Although observational, the study's connections are significant, indicating a potential 30 percent higher chance of bone fracture at the highest PFAS exposure levels. The researchers point to vitamin D disruption as a possible mechanism, crucial for bone development. PFOA, despite a global ban under the Stockholm Convention due to its known harms, remains prevalent in the environment. This research underscores the urgency for continued studies into adulthood and efforts to mitigate PFAS exposure during critical developmental stages.
