Study: Proximity to fast-food restaurants linked to stroke risk

A person's risk of stroke is associated with the number of fast-food restaurants near their residence, according to a study presented Thursday at a stroke conference in San Diego, California.

Researchers led by Dr. Lewis B. Morgenstern at the University of Michigan in Ann Arbor counted 1,247 strokes caused by blood clots in 64 census tracts in Nueces County, Texas, which includes Corpus Christi, from January 2000 through June 2003. "The association suggested that the risk of stroke in a neighborhood increased by 1 percent for every fast-food restaurant," the authors wrote in a poster presented at the American Stroke Association's International Stroke Conference.

Residents of neighborhoods in the 75th percentile of fast-food restaurants had a 6 percent increased risk of stroke compared with residents of the 25th percentile of such eateries, according to the study, which was paid for by the National Institute of Neurological Disorders and Stroke.
