Study published in JAMA indicates link between proximity to golf courses or shared water supply with them, and the increased risk of developing Parkinson’s Disease, noting heavy pesticide use of golf courses.
Spoiler: it’s the pesticides. Researchers found that those living within a mile of golf courses have 126 percent higher risk of developing Parkinson’s disease than those who live more than six miles away, according to a new study published in the Journal of the American Medical Association (JAMA).
Areas that shared drinking water supplies with water used near golf courses were the most greatly impacted, the study shows. Researchers believe this shows that the pesticides used on golf courses could contribute to the amount of Parkinson’s cases.
“The odds of PD were relatively constant within close proximity to a golf course and decreased linearly as distance increased; individuals living farther from a golf course had reduced odds of PD, decreasing relative to the distance from the nearest golf course,” the study explained.
Previous studies have already linked chemicals found in pesticides including paraquat and rotenone to neurodegeneration, according to the study.
“This isn’t about golf,” said Dr. Michael Okun, national medical adviser for the Parkinson’s Foundation. “It’s about pesticides, environmental exposures, and preventable risks hiding in plain sight.”
