Use of certain personal care products during pregnancy may impact maternal hormone levels, according to a new Rutgers study. Personal care and beauty products contain several ingredients that often include a wide range of endocrine-disrupting chemicals like phthalates, parabens, phenols and toxic metals. These chemicals interact with hormone systems, influencing synthesis, regulation, transport, metabolism and hormone reception, which are all especially vulnerable during pregnancy. The National Institute of Environmental Health Sciences and National Institutes of Health-funded study, published in Environmental Research, examined the association between personal care product use and the levels of sex steroid hormones, including estrogens and progesterone and thyroid hormones among pregnant women. The researchers also explored how demographic factors impact the use of certain personal care products. To read the full story.
