New BPA Study Finds Links to Adverse Effects in Older Women

Another study has found links between the controversial chemical hardener <"">Bisphenol A (BPA) and adverse health effects. Environmental Health News wrote that menopausal women tend to be likelier to suffer BPA-related health effects, such as inflammation and oxidative stress over women who are still menstruating and men.

The study looked at 259 Korean adult men, 92 premenopausal women, and 134 post-menopausal women and was the first study of its kind to link the conditions in people to BPA, said Environmental Health News, which added that the study suggests women in menopause could be more susceptible to the estrogen-mimicking effects in BPA that prompt this type of cell damage. Environmental Health News noted that oxidative stress could occur with “aging, cancer, and other disease states.”

Yesterday we wrote that another new study found that BPA might “impair” female reproductive cell growth and function, according to the University of Illinois. Last month we wrote that research conducted by the North Carolina State University and the National Institute of Environmental Health Sciences (NIEHS), found BPA to significantly affect reproductive health at levels that are either the same or even lower that those believed not to cause adverse effects, citing Science Daily.

BPA is a ubiquitous hormone interrupting chemical that can be found in baby bottles, sippy cups, water bottles, canned foods, and countless other products.

The Korean study team looked at inflammation and oxidative stress markers in the participants’ blood and compared them BPA in their urine. Medical, lifestyle, exposure, and demographic information was collected said Environmental Health News. BPA was found in the urine of 76 percent of the participants, said Environmental Health News. The links between BPA levels and oxidative stress and inflammation were only seen in postmenopausal women, with oxidative stress levels higher in older women who also had higher levels of BPA. BPA exposure in men and premenopausal women did not correlate to inflammation or oxidative stress markers, said Environmental Health News.

Most disturbing was that the Korean participants were less exposed to BPA than U.S. and Japanese adults in prior studies, with BPA levels in the participants lower that seen in U.S. adults and Japanese women, said Environmental Health News. This points to an issue with an increased risk of inflammation and oxidative stress in the U.S. and Japan.

Environmental Health News explained that BPA’s negative health effects relate to its ability to mimic estrogens, hormones critical to “female development, fertility, menopause, cardiovascular disease, and breast cancer”; estrogens are also important for men. Oxidative stress is believed to contribute to aging and cancer, and oxidative stress and inflammation are linked to diabetes, cardiovascular disease, and the spread of cancer, said Environmental Health News.

BPA has been connected to a wide variety of adverse effects, namely: Increased risks of brain, reproductive, cardiac, and immune system diseases and disorders; problems with liver function testing; interruptions in chemotherapy treatment; links with serious health problems based on over 200 studies which found it to have negative effects at doses lower than the FDA’s current standards; retention in the body longer than was previously believed; leeching into liquids being held in containers regardless of whether the containers are or are not heated; and longer lasting damage, which can also be passed to future generations.
