I came across this article and found it very interesting and want to share it. According to a new study at Washington University School of Medicine in St. Louis, women whose bodies have high levels of chemicals found in every day use of plastics, personal-care products, common household items and the environment experience menopause two to four years earlier than women with lower levels of these chemicals have been linked to an early decline in ovarian function. The findings are reported online Jan. 28 in the journal PLOS ONE.
Researchers looked at levels in blood and urine of 111 chemicals that are suspected of interfering with the natural production and distribution of hormones in the body. While several smaller studies have examined the link between so-called endocrine-disrupting chemicals and menopause, the new research is the first to broadly explore the association between menopause and individual chemicals on a large scale, using a nationally representative sample of patients across the United States.
“Chemicals linked to earlier menopause may lead to an early decline in ovarian function, and our results suggest we as a society should be concerned,” said senior author Amber Cooper, MD, an assistant professor of obstetrics and gynecology.
When there is a decline in ovarian function, it not only can adversely affect fertility but can lead to earlier development of heart disease, osteoporosis and other health problems which are already linked to the chemicals including certain cancers, metabolic syndrome and, in younger females, early puberty.
Many of these chemical exposures are beyond our control because they are in the soil, water and air. It is very important to educate ourselves about our day-to-day chemical exposures and become more aware of the plastics and other household products we use.
To better protect ourselves, it is recommended that people microwave food in glass or paper containers instead of in plastic and styrofoam cups and other products. We also need to learn more about the ingredients contained in cosmetics, personal-care products and food packaging we use every day.
Although many of the chemicals included in the study have been banned from U.S. production because of their negative health effects, they still are produced globally and are damaging to the environment.
In the study, data was taken from 31,575 people, including 1,442 menopausal women who had been tested for levels of endocrine-disrupting chemicals. It is important to know that the average age of these women was 61. None were using estrogen-replacement therapies or had had surgery to remove their ovaries.
This survey was designed so that the women who had undergone chemical testing would represent a population of almost 9 million menopausal women. The women’s blood and urine samples were analyzed for exposures to 111 mostly man-made chemicals, which included known reproductive toxins and/or those that take more than a year to break down. Chemicals from the following categories were analyzed in the survey: dioxins/furans (industrial combustion byproducts); phthalates (found in plastics, common household items, pharmaceuticals and personal-care products including lotions, perfumes, makeup, nail polish, liquid soap and hair spray); phytoestrogens (plant-derived estrogens); polychlorinated biphenyls (PCBs, coolants); phenolic derivatives (phenols, industrial pollutants); organophosphate pesticides; surfactants; and polycyclic aromatic hydrocarbons (combustion products).
The researchers identified 15 chemicals — nine PCBs, three pesticides, two phthalates and a furan (a toxic chemical) — that warrant closer evaluation because they were significantly associated with earlier ages of menopause and potentially have detrimental effects on ovarian function.
Earlier menopause can alter the quality of a woman’s life and has profound implications for fertility, health and our society. Understanding how the environment affects health is complex. Even though this study doesn’t prove causation, the associations do raise a red flag and supports the need for future research.
We need to do all we can to improve our products and prevent women suffering from actually using the toxic products on the market.
