Abstract
A recent study reported that mortality from stroke in children and adolescents decreased by 58% from 1979 to 1998, although it wasn't clear if the case fatality or the incidence of stroke in this age group is decreasing. We report trends of stroke incidence and case fatality in children and adolescents within a large biracial population. The study involved collection of all strokes in the study population between January 1, 1988 and December 31, 1989, July 1, 1993 and June 30, 1994, and January 1, 1999 and December 31, 1999, at all of the regional hospitals serving the Greater Cincinnati/Northern Kentucky population (only the children's hospital in 1988). Study nurses reviewed the medical records of all inpatients with stroke-related discharge diagnoses and abstracted relevant data. A study physician reviewed each abstract to determine whether a stroke or transient ischemic attack had occurred. A total of 54 strokes occurred in children or adolescents younger than 20 years during the three study periods (30% African American, 70% Caucasian, and 56% female). The overall incidence rate of all strokes in children younger than 15 years was 6.4/100,000 in 1999, a nonsignificant increase when compared to 1988. The 30-day case-fatality rates were 18% in 1988—1989, 9% in 1993—1994, and 9% in 1999. We found that the incidence of strokes in children has been stable over the past 10 years. The previously reported nationwide decrease in overall stroke mortality in children might be due to decreasing case fatality after stroke and not decreasing stroke incidence. Based on our data, we conservatively estimated that approximately 3000 children less than 20 years old would have a stroke in the United States in 2004.
