Background: Understanding the trends of stroke incidence and how those strokes are distributed across race is a critical step to implement trials programs decrease burden caused by nationally. In 2015, we reported that decreasing in both Black White adults. We investigated continued 2020. Methods: this population-based surveillance study, all cases within 5-county population surrounding Cincinnati adults aged ≥20 years were ascertained during full year every 5 from 1993 Cases abstracted study nurses adjudicated trained physicians. Temporal evaluated age, (Black or White), subtype (ischemic (IS), intracranial hemorrhage (ICH), subarachnoid (SAH)). Stroke rates per 100,000 individuals 2020 calculated using US Census data age-, race-, sex-standardized as appropriate. Trends linear regression. Disparities risk ratios with 95% CIs. Results: 2020, identified 2280 first-ever strokes. Of these, 23% (N=524) 52% (N=1,177) female. The overall annual was 203/100,000. Table 1 reports temporal for For races, any increased between 2015 (p=0.003, driven largely an increase adults), while trend since no longer declining. Ischemic also (pairwise comparison, p=0.011) races. Figure shows rate (any subtype) over time. ratio incident RR 1.84 (1.66, 2.02; p-value 0.022). Conclusions: Compared our analysis after time decreasing. Between observed increasing population. first 27-year period report significant incidence, mostly ischemic whites. ICH/SAH stably higher blacks compared More work needs be done investigate possible association COVID other traditional factors address racial disparities burden.
