Experts: Vitamin D May Explain The Association
http://www.koat.com/health/30352727/detail.htmlPeople who live in areas with the least amount of sunlight may have a greater risk for stroke, according to findings presented at the American Stroke Association's International Stroke Conference in New Orleans this week.Strokes occur when blood and oxygen is cut off from the brain due to a blood clot or a burst blood vessel. Stroke is the fourth leading cause of death in the United States and the number one cause of disability, according to the American Stroke Association.What's unique about this study, explained professor Leslie A. McClure, a biostatistician from the University of Alabama at Birmingham, is that her team used NASA satellite and ground monitor data to determine sunlight and temperature exposure and how it corresponded with the stroke risk of study participants.When the different factors were compared, McClure said they found that people who had less than the midpoint level of sun exposure were at 60% increased risk for stroke. The study also confirmed previous findings that both hot and cold temperature exposure is associated with higher stroke incidence.The UAB researchers used data from the REGARDS (REasons for Geographic and Racial Differences in Stroke) project, a long term study that includes more than 30,000 Caucasian and African American participants, age 45 and older. The study is funded by the National Institutes of Health.
