Area of Science:

  • Epidemiology
  • Neurology
  • Public Health

Background:

  • Stroke incidence and outcomes vary globally.
  • Understanding regional variations is crucial for targeted public health interventions.
  • The Sino-MONICA-Beijing study aimed to provide comprehensive stroke data for Beijing.

Purpose of the Study:

  • To determine the incidence and case fatality rates of stroke in Beijing.
  • To compare Beijing's stroke rates with international data.
  • To investigate sex-based differences in stroke incidence, outcomes, and healthcare utilization.

Main Methods:

  • Prospective population-based study of 700,000 residents aged 25-74 in Beijing (1984-1986).
  • Adherence to WHO Collaborative Study criteria for comparability.

  • Analysis of 2,593 registered stroke events, including computerized tomography confirmation for a subset.

    • Main Results:

    • Overall stroke incidence was 189.5/100,000, with first stroke incidence at 133.6/100,000.
    • Men exhibited higher stroke incidence rates than women (OR=1.32 for all strokes).
    • Beijing showed higher age-adjusted stroke incidence, particularly hemorrhagic stroke, compared to other countries. Women had a higher 4-week case fatality rate (39.5% vs. 32.8% for men).
    • Men had higher hospitalization rates; women were more frequently treated at home.

    Conclusions:

    • Stroke incidence in Beijing was higher than in many international regions, with a notable proportion of hemorrhagic strokes.
    • Despite higher incidence, men had better survival rates post-stroke compared to women.
    • Disparities in hospitalization and home treatment suggest potential differences in healthcare access or utilization by sex.
