Stroke incidence fell 33% overall but not in those <65; leaves open targeted prevention needs and generalizability.
Altogether, 456 and 413 first-ever stroke patients were identified during the earlier and later time periods respectively. The age- and sex-standardized stroke incidence rates decreased from 246 (95% CI 224-270) to 165 (95% CI 149-182) per 100,000 people. However, incidence remained unaltered among those <65 years. Early case-fatality decreased from 14 to 11% (p = 0.165). -Conclusion: First-ever stroke incidence in southern Sweden has decreased with 33% since the beginning of this millenni-um. Incidence rates have decreased among the elderly but remain unchanged among younger age groups. Our findings warrant further studies on trends in risk factor profiles and effects of prevention strategies, and heightened focus on stroke in the young.
