In the ongoing Northern Manhattan Study, metabolic syndrome was the culprit in 35% of strokes in Hispanics, 8% of strokes in blacks, and 4% of strokes in whites. The study was funded by the National Institute of Neurological Disorders and Stroke.
"A better understanding of race/ethnic differences in the impact of metabolic syndrome will help effectively target populations at increased risk of stroke," said Dr. Boden-Albala of the Neurological Institute at Columbia University, New York.
For the study, which began in 1990, Dr. Boden-Albala and her associates obtained a medical history, blood pressure, anthropometric measures, and fasting plasma glucose levels from 3,298 stroke-free residents of Northern Manhattan.
The study participants were followed annually by telephone to track outcomes, including stroke, myocardial infarction, or death. Those participants who reported having had a stroke or MI were evaluated in person by investigators.
At baseline, the mean age of the participants was 69 years. More than half (63%) were women, 21% were white, 25% were black, and 54% were Hispanic, said Dr. Boden-Albala, the study's research director.
