Determine the incidence of first-ever stroke and its clinical subtypes in an adult population using standardized diagnostic criteria.
Monitored first-ever stroke cases from 1976 through 1978 using a population-based stroke registry covering 75,000 residents with an estimated referral sensitivity exceeding 85%.
Applied World Health Organization diagnostic criteria, requiring in-person clinical examinations by staff physicians for all living suspected cases.
Average annual incidence among residents aged ≥20 years was 2.61 per 1,000 overall, with higher rates in males (3.42 per 1,000) than females (1.88 per 1,000), reflecting a 2:1 male-to-female ratio.
Annual subtype-specific incidence rates were 1.51 per 1,000 for cerebral infarction, 0.61 per 1,000 for cerebral hemorrhage, and 0.20 per 1,000 for subarachnoid hemorrhage.
Stroke incidence increased progressively with age, displaying the strongest association for cerebral infarction, while no subarachnoid hemorrhages occurred in residents aged ≥70 years.

Implication

Population-based registry study reveals higher stroke incidence in males and distinct subtype patterns, indicating pronounced sex differences in cerebrovascular risk.
