TUESDAY, Aug. 13 (HealthDay News) -- Stroke rates in older white
and Mexican Americans declined over the past decade but remain
higher in Mexican Americans, researchers have found.
The study looked at the incidence of ischemic stroke -- which is
the most common type of stroke and is caused by a clot in the blood
vessels of the brain -- among people aged 45 and older who lived in
Corpus Christi, Texas, between 2000 and 2010.
During that time, more than 4,600 people in the study group
experienced an ischemic stroke (2,604 Mexican-Americans and 2,042
whites). There was a 36 percent decline in the overall ischemic
stroke rate in both groups during the study period, but it was
limited to people 60 and older.
The researchers also found that Mexican-Americans aged 45 to 74
were still 34 percent more likely than whites to suffer an ischemic
stroke, according to the study published Aug. 13 in the journal
Annals of Neurology.
"The dramatic decline in stroke rates during the last decade is encouraging," lead author Dr. Lewis Morgenstern, of the University of Michigan Medical School in Ann Arbor, said in a journal news release. "However, the ongoing disparity among younger patients emphasizes the need for further interventions to prevent stroke, particularly among young Mexican-Americans."
Morgenstern noted that Mexican-Americans are one of the largest
and fastest growing minority groups in the United States.
"In minority groups, stroke occurs at much younger ages, often resulting in greater disability and significantly higher costs," Morgenstern said.
The cost of stroke in the first half of this century in the
United States could be more than $1.5 trillion, according to
Based on U.S. Census estimates, Hispanics/Latinos currently
account for 17 percent of the U.S. population and that is projected
to increase to more than 30 percent by 2050.
