Arsenic Exposure Linked to Diabetes
Monday, September 8th, 2008(Beyond Pesticides, September 8, 2008) Inorganic arsenic may increase the risk of developing type 2 diabetes, according to a study published in the Journal of the American Medical Association by researchers at the Johns Hopkins Bloomberg School of Public Health. Common sources of inorganic arsenic exposure include dietary exposure, drinking water pollution, and contamination associated with arsenic wood preservatives such as sawdust, smoke, direct contact, and hazardous waste sites. The study found that individuals with diabetes have higher levels of arsenic in the urine compared to individuals without diabetes. Researchers examined randomly selected urine samples taken from 788 U.S. adults 20 years or older that participated in a 2003-2004 National Health and Nutrition Examination Survey. The results were adjusted for diabetes risk factors, including body mass index and for organic arsenic compounds found in seafood. “Our findings suggest that low levels of exposure to inorganic arsenic may play a role in diabetes,” said Ana Navas-Acien, MD, PhD, lead author of the study and assistant professor with the Bloomberg School’s Department of Environmental Health Sciences. “While prospective studies are needed to establish whether this association is causal, these findings add to the existing concerns about the long-term health consequences of low […]
