Children with more exposure to per- and polyfluoroalkyl substances, or PFAs, had lower forearm density by age 12 and could face greater fracture risk, researchers found, with girls apparently more vulnerable than boys.

Reducing PFAS Exposure

According to lead author Jessie P. Buckley, professor of epidemiology at the University of North Carolina, adolescence is a key period for building strong bones, and achieving optimal bone mass during this time can reduce lifelong risks of fractures and osteoporosis. Buckley stated that reducing PFAS exposure during key developmental windows could support healthier bones throughout life.

PFAs are a class of fluorinated compounds used in industrial and consumer products for their stain- and water-resistant properties. People are exposed to these chemicals through consumer products, indoor air, dust, drinking water, seafood, and proximity to contaminated areas. PFAs are persistent in the environment and take years to diminish once inside the body.

A key exposure window seems to be during pregnancy. The UNC researchers compared the amount of PFA compounds in infants’ umbilical blood and at ages 3, 8, and 12 years, to bone density measurements taken at age 12.

Choosing cookware without PFAs and filtering drinking water might help reduce exposure. Standard carbon filter pitchers won’t cut it, according to information from the Colorado Department of Public Health and Environment. Look for manufacturers that have demonstrated that the water filter can remove PFAs to nondetectable levels.
