San Diego, CA, May 3, 2013- Postmenopausal women who increase their physical activity may reduce their risk of kidney stones, according to a new study at the 108th Annual Scientific Meeting of the American Urological Association (AUA). The study will be presented to the media during a special press conference on Saturday, May 4 at 11:30 a.m. at the San Diego Convention Center.

Kidney stones are a significant health concern with more than three million people visiting a health care provider and more than half a million visiting emergency rooms each year. While obesity is known to be a strong risk factor for kidney stone development, the role of physical activity and dietary energy intake in lowering this risk remains inadequately understood. Researchers from several leading institutions including University of California, San Francisco Medical Center, Georgetown University and University of Washington School of Medicine, conducted a study designed to evaluate the relationship between kidney stone formation and physical activity, dietary energy intake and body mass index (BMI).  

Researchers used data from the Women’s Health Initiative Observational Study and identified 85,225 postmenopausal women as participants. Adjusting for age, race, region, and dietary water, sodium, animal protein and calcium intake, data suggests:

“Kidney stones are a very common health condition, and as with most health conditions, prevention is key," said AUA spokesperson Kevin T. McVary, MD. “While we know diet is one of several factors that can promote or inhibit kidney stone development, this study shows lifestyle changes such as exercise can also help prevent stones from forming in postmenopausal women. Further research is needed to understand if this observation is accurate for other demographics.”
