Insights
Stroke type distribution in China shows ischemic stroke is more common overall. Prevention strategies should target hemorrhagic stroke in older adults and ischemic stroke in younger individuals.
Area of Science:
- Neurology
- Epidemiology
- Public Health
Context:
- Stroke is a leading cause of death and disability globally.
- Understanding stroke type distribution is crucial for effective prevention and treatment.
- China faces a significant burden of stroke, necessitating localized epidemiological data.
Purpose:
- To analyze the distribution characteristics of stroke types in China.
- To identify demographic variations in stroke type prevalence.
- To evaluate the impact of intervention strategies on stroke incidence.
Summary:
- A prospective study in urban Chinese communities (300,000 people) analyzed 2,570 first-time stroke cases.
- Results indicated ischemic stroke (62.3%) was more prevalent than hemorrhagic stroke (37.1%).
- Hemorrhagic stroke predominated in individuals under 50, while incidence rates were lower in intervention areas.
Impact:
- Findings inform targeted stroke prevention, emphasizing hemorrhagic stroke for those over 50 and ischemic stroke for those under 50.
- The study highlights the potential effectiveness of community-based interventions in reducing stroke incidence.
- This research provides critical data for public health policies and clinical practice in China and similar populations.
Objective:
To analyze the distribution characteristics of types of stroke in china.
Methods:
A prospective study and comprehensive prevention were conducted in urban communities with 300 000 people in Changsha, Beijing and Shanghai, and 2 570 case of stroke at their first occurance were selected with established typing diagnosis (r).
Results:
Hemmorrhagic, ischemic, and unclassified stroke accounted for 37.1%, 62.3%, and 0.6% respectively. The proportion of hemmorrhagic stroke was more than 50 percent among persons under 50. The average yearly incidence of stroke was 142.3/100 thousand in the intervention areas and was 187.0/100 thousand in the control areas.
Conclusion:
Prevention should be focused on hemorrhagic stroke for those aged over 50 and on ischemic stroke for those aged less than 50. The average incidence rates of hemmorrhagic and of ischemic stroke were lower in the intervention area than in the control area.
