ISLAMABAD: Exposure to certain common chemicals called endocrine-disrupting chemicals found in several consumer products, including plastic bottles, may reduce levels of vitamin D in the bloodstream, said a study.
Endocrine-disrupting chemicals (EDC) are found in everyday products and throughout the environment.
Bisphenol A (BPA), a known EDC, is often found in plastics and other consumer products.
“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 from the University of Michigan School of Public Health.
The study examined data from 4,667 US adults who participated in the National Health and Nutrition Examination Survey (NHANES) between 2005 and 2010.
The participants provided blood samples so their vitamin D levels could be measured.
To measure EDC exposure, the participants had their urine analysed for substances left behind after the body metabolised phthalates and BPA, Medical Xpress reported.
The study, found people who were exposed to larger amounts of phthalates were more likely to have low levels of vitamin D in the bloodstream than the participants who were exposed to smaller amounts of the EDCs. The link was strongest in women.
There also was an association between exposure to higher levels of BPA and reduced vitamin D levels in women, although the relationship was not statistically significant in men.-APP
