Abstract:
Objectives: To monitor stroke morbidity and mortality in 2 rural communities of Shanghai and to provide a reference for stroke prevention and epidemiological study. Methods: A modified cluster-sampling method was used to extract about 100 000 natural populations in the 2 communities of Fengxian District, Shanghai. The demographic data were collected annually. In the monitored populations, the tertiary monitoring network was established to investigate the morbidity and mortality of stroke, and to analyze and monitor the morbidity and mortality and the distribution of clinical types of stroke in the populations from 2008 to 2010. The morbidity and mortality of stroke were adjusted by the National Population Sample Survey 2009. Results: Circled digit oneA total of 100 622 subjects were monitored from 2008, and 304 306 person times were monitored cumulatively up to 2010. A total of 585 subjects had first attack of strokes and 313 died. The morbidity in the 3 years was 275.3/100 000, 173.5/100 000 and 129.3/100 000, respectively, and the average annual stroke morbidity was 192.2/100 000; the standardized morbidity was 180.7/100 000, 115.3/100 000 and 81.7/100 000, respectively. The stroke mortality was 113.3/100 000, 102.1/100 000 and 93.3/100 000, respectively. The average annual stroke mortality was 102.9/100 000; the standardized mortality was 73.5/100 000, 67.5/100 000 and 57.2/100 000, respectively. Circled digit twoIn the <45, <45 to 64 and ≥65 age groups, the average annual morbidity was 4.9/100 000, 122.8/100 000 and 913.8/100 000, respectively, and the average annual mortality was 2.8/100 000, 22.6/100 000 and 591.8/100 000, respectively. The differences were statistically significant (P < 0.01). Circled digit threeThere was no significant difference in the average annual morbidity and mortality between the genders. In the 45 to 64 age group, the average annual morbidity and mortality were 156.7/100 000 and 32.0/100 000 in males; while the average annual morbidity and mortality were 90.4/100 000 and 13.6/100 000 in females. The differences were statistically significances (P < 0.01). Circled digit fourThe constituent ratios of intracerebral hemorrhage, cerebral infarction, subarachnoid hemorrhage and unclassified stroke were 22.6%, 75.7%, 0.9% and 0. 9%, respectively. Conclusion: The stroke morbidity and mortality in the rural communities of Shanghai are 192.2/100 000 and 102.9/100 000. The morbidity and mortality increased with age. The stroke morbidity and mortality in males is higher than those in females in the 45 to 64 age group. The proportion of patients with cerebral infarction is significantly higher than intracerebral hemorrhage.
