Cardiovascular disease risk heightened by Pesticide exposure

heartThe harmful impact of Pesticides is not only confined to environmental exposure but harms the body’s metabolic response by increasing cardiovascular disease and in premenopausal women. The study was published in the Endocrine Society’s Journal of Clinical Endocrinology & and investigated the impact of exposure to polychlorinated pesticides such as DDT.

Although DDT has been banned in the U.S. the lingers due to the cumulative exposure of these pesticides and it remains widespread in the environment and supply. DDT was one of the first chemicals recognized as a hormone disrupting chemical interfering with the . DDT and related pesticides are known as environmental estrogens because they can mimic and interfere with the function of the hormone estrogen.

The study population consisted of 121 obese women who underwent bariatric surgery at S. João Hospital in Porto. Among the participants, 73 were classified as premenopausal and 48 were postmenopausal, and the study analyzed the amount of endocrine-disrupting chemicals in fat tissue and .

“After the body breaks down DDT along with similar pesticides, chemical remnants called metabolites accumulate in women’s fat tissue,” said one of the study’s authors, Diana Teixeira, PhD student of the Faculty of Medicine, University of Porto in Porto, Portugal. “When higher amounts of these environmental estrogens collect in the fat tissue, it can compromise the protective effect the body’s natural estrogen has on a premenopausal woman’s heart . This leaves women at increased of developing cardiovascular disease and .”

The study findings revealed that among premenopausal women, women with higher concentrations of environmental estrogens in their visceral fat tissue from the belly were more likely to have higher average . Among premenopausal women, those with higher levels of environmental estrogens in their blood tended to have more and faced a greater .

“Our findings show that endocrine-disrupting chemicals tend to aggravate complications of obesity, including and cardiovascular disease , in premenopausal women,” Teixeira said. “Measuring environmental estrogen levels may help physicians identify women who are at of developing cardiovascular and metabolic disease so they can take preventative action.”
