DDT exposure may affect three generations of women with increased health risks: study

  TORONTO Young women today whose grandmothers were exposed to the pesticide DDT may face increased health risks, including those linked to breast cancer and diabetes, a new U.S. study has found. The study from the Public Health Institute’s Child Health and Development Studies (CHDS) and the University of California at Davis is the very first of its kind to examine the health effects of exposure to a toxic environmental chemical over three generations. The study, published in Cancer Epidemiology, Biomarkers and Prevention, a journal from the American Association for Cancer Research, found that granddaughters whose grandmothers were exposed to the pesticide DDT have higher rates of obesity and earlier first menstrual periods – which may increase their risk for breast cancer, high blood pressure, diabetes and other cardiometabolic diseases.
