Implication

Prospective register reports TIA incidence in Oxfordshire, highlighting age and gender disparities.

Key Points

  • To determine the incidence of transient ischemic attacks (TIAs) in a defined population in Oxfordshire, England.
  • Conducted a prospective register of new stroke and TIA cases from November 1981 to October 1986.
  • Recorded TIA presentations from general practitioners and hospitals in a population of 105,000 residents.
  • Calculated crude and age-standardized TIA incidence rates. including data on distribution patterns.
  • The crude annual incidence rate of TIA was 0.35 per 1,000, with a standardized rate of 0.42 per 1,000.
  • Approximately 21,000 new TIA cases are estimated annually in England and Wales, with a notable increase among those over 70.
  • Men in middle age showed significantly higher TIA occurrence with an odds ratio of 2.6 compared to women.
