Abstract
Background
Stroke has become a major burden and public health problem in rural China. We aimed to comprehensively assess the current status of stroke burden as well as the associated risk factors in rural northeast China.
Methods
This population-based, cross-sectional study was conducted in 10,926 adults (response rate 85.3%) aged ≥40 years residing in rural northeast China. A multistage cluster sampling method was used to select the representative sample. The prevalent stroke cases were considered as stroke survivors on 31 August 2017. Stroke was diagnosed according to the World Health Organization’s recommendations and was classified as ischemic stroke and hemorrhagic stroke based on the results of computed tomography or magnetic resonance imaging. The status of related risk factors was also evaluated.
Results
Of the 10,926 participants, 731 were diagnosed with stroke (602 patients with ischemic stroke, 151 with hemorrhage stroke, and 22 with both ischemic stroke and hemorrhage stroke). The crude prevalence of overall stroke, ischemic stroke, and hemorrhage stroke was 6690.5, 5509.8, and 1382.0 per 100,000 people, respectively, and the age-standardized rate was 4903.8, 4041.7, and 990.9 per 100,000 people. Among the overall stroke population, 13.4% were living with consequences of stroke. Hypertension (86.7%), dyslipidemia (37.2%), and diabetes (24.5%) were highly prevalent in stroke participants. However, most of those comorbidities remained uncontrolled (93.7, 44.7, and 88.9%, respectively).
Conclusion
The burden of stroke in rural northeast China was substantial, with a high prevalence of stroke, recurrence, and disabilities. Uncontrolled comorbidities will likely contribute to recurrence and worsening disabilities in the coming decades. Strategies of long-term management of stroke and related risk factors are urgently required in rural northeast China.
