Chemical exposure linked to lower vitamin D levels
Endocrine-disrupting chemicals may alter active form of vitamin in body
The Endocrine Society
Exposure to bisphenol A (BPA) and other endocrine-disrupting chemicals (EDCs) may reduce levels of vitamin D in the bloodstream, according to a new study published in the Endocrine Society's Journal of Clinical Endocrinology & Metabolism.
The study is the first to find an association between EDC exposure and vitamin D levels in a large group of U.S. adults.
EDCs are chemicals or mixtures of chemicals that can cause adverse health effects by interfering with hormones in the body. The Society's Scientific Statement on EDCs examined more than 1,300 studies that found links between chemical exposure and health problems, including infertility, obesity, diabetes, neurological problems and hormone-related cancers.
"Nearly every person on the planet is exposed to BPA and another class of endocrine-disrupting chemicals called phthalates, so the possibility that these chemicals may even slightly reduce vitamin D levels has widespread implications for public health," said the study's first author, Lauren Johns, MPH, a PhD candidate at the University of Michigan School of Public Health in Ann Arbor, MI. "Vitamin D plays a broad role in maintaining bone and muscle health. In addition, low vitamin D levels have been implicated in outcomes of numerous conditions such as cardiovascular disease, diabetes and cancer."
EDCs are found in everyday products and throughout the environment. There are more than 85,000 manufactured chemicals, of which thousands may be EDCs. BPA, a known EDC, is often found in plastics and other consumer products. Another group of chemicals linked to hormone disruption, phthalates, are found in personal care products such as cosmetics, children's products, food packaging and medical tubing.
