Uhl finds association between PFCs and osteoarthritis in women
In what researchers are calling a first, a new analysis suggests that the greater a woman's exposure to a type of common chemical compound called PFCs, the greater her risk for developing osteoarthritis.
Researchers did not find a similar risk among men regarding these chemicals, which are now found in everything from nonstick cookware to take-out containers and carpeting.
Osteoarthritis, the most common type of arthritis, causes pain and stiffness and involves degeneration of the cartilage in the joints.
And the study authors stressed that while their investigation identified a robust link between osteoarthritis and exposure to two specific PFC chemicals -- known as PFOA and PFOS -- for now the finding can only be described as an association, rather than a cause-and-effect relationship.
"But we did find a clear and strong association between exposure to [these] compounds and osteoarthritis, which is a very painful chronic disease," said study lead author Sarah Uhl, who conducted the study while working as a researcher at the Yale School of Forestry and Environmental Studies in New Haven, Conn.
"This adds to the body of information that we have suggesting that these highly persistent synthetic chemicals are of concern when it comes to the public health," she said.
The new study appears in the Feb. 14 online issue of Environmental Health Perspectives
