Rate of acute ischemic stroke hospitalizations up in those aged 5 to 44 years but down in older adults
WEDNESDAY, Feb. 9 (HealthDay News) -- Hospitalizations for acute ischemic stroke decreased between 1994 and 2007 among men and women aged 45 years and older but significantly increased among those aged 5 to 44 years, according to research presented at the American Stroke Association's International Stroke Conference 2011, held from Feb. 9 to 11 in Los Angeles.
Xin Tong, M.P.H., of the U.S. Centers for Disease Control and Prevention's Division for Heart Disease and Stroke Prevention in Atlanta, and colleagues evaluated 1994 to 2007 hospitalizations from the Nationwide Inpatient Sample of the Healthcare Cost and Utilization Project to provide population-based estimates of trends in acute ischemic stroke hospitalizations by age and gender.
Between 1994 and 2007, the rate of hospitalizations decreased by 51 percent in girls aged 0 to 4 years, 25 percent in men aged 45 and older, and 29 percent in women aged 45 and older. The investigators also found that the number of acute ischemic stroke hospitalizations increased 51 percent among males aged 15 to 34 years and 17 percent among their female counterparts. In addition, the number of acute ischemic stroke hospitalizations increased 31 percent in boys and 36 percent in girls aged 5 to 14 years. The investigators also found that the rate of hospitalizations increased 47 percent among men and 36 percent among women aged 35 to 44 years. All trends were statistically significant.
"Our results from national surveillance data punctuate the need to further investigate socio-demographic, clinical, and health care factors associated with the recent increase in acute ischemic stroke hospitalizations among the younger population," the authors write.
