Objectives1. To estimate sex- and race-specific incidence of pediatric stroke by age group 2. To describe trends in pediatric stroke incidence in New York(NY) from 2006 to 2016 MethodsInternational Classification of Disease codes were used to retrospectively to identify all acute ischemic stroke (AIS), intracerebral hemorrhage (ICH), subarachnoid hemorrhage (SAH), and cerebral venous thrombosis (CVT) admissions in pediatric patients (0-19 years old [yo]) in the 2006-2016 NY State Inpatients Database (SID; total N=4,083). Incident counts were combined with annual US Census data to compute age- and sex-specific incidence. Joinpoint regression was used to evaluate trends in incidence over time. ResultsAcross the study period, 52% of all pediatric strokes were AIS, 23% ICH, 11% SAH, and 14% CVT. Total stroke incidence/100,000 population was 47.8 and the age-standardized incidence in >=1yo was 4.8. Incidence differed by age (1-4yo4.4, 5-9yo3.6, 10-14yo4.5, and 15-19yo6.7), but not by sex. Age-standardized incidence of strokes in >=1yo also differed by race (Blacks 5.9, Whites 4.0, Hispanics 3.3, Asians/Pacific Islanders 3.1). While there was no change in overall stroke, AIS, or SAH incidence, ICH (annualized percentage change [APC] 4.3%, 95%CI 1.7-6.9) and CVT (APC 4.1, 95%CI 1.22-6.25%) increased over time. When stratified by age, overall stroke incidence increased over time in 15-19 yo (APC 1.3%, 95%CI 0.27-2.35, p=0.019), but not in other age groups. ConclusionWe observed increasing incidence in pediatric ICH, CVT, and overall stroke in 15-19 yo in the state of NY. Pediatric stroke incidence in NY is disproportionately higher in blacks compared to other races. Further investigation is warranted to determine the association of these changes with risk factors, lifestyle and systems of care.
