Abstract
BACKGROUND: Stroke has been emerging as the major public health challenge in China. In the present study, we sought to comprehensively estimate of stroke burden in urban northeast China. METHODS: We conducted the cross-sectional study in 5424 adults aged ≥ 40 years (response rate was 85.3%) living in urban northeast China. A multi-stage cluster sampling method was employed to ensure the population was representative. The prevalent stroke patients were defined as survivors on 31 March 2018. Stroke was defined based on the WHO criteria and was classified into ischemic stroke (IS) and hemorrhage stroke (HS) according to the imaging results. RESULTS: A total of 292 stroke cases were confirmed (IS-260, 35-HS, and IS concomitant HS-3). Crude prevalence of overall stroke, IS and HS were 5.4%, 4.8% and 0.6%, respectively, and the age-standardized prevalence was 3.8%, 3.4% and 0.5%, respectively. The prevalence of stroke was significantly higher in men compared to women. Among stroke population, 4.5% had disabilities and lived with consequences of stroke. Hypertension, dyslipidemia and diabetes were highly prevalent, accounting for 80.5%, 59.7% and 39.3%, respectively, in stroke population. However, the control rates of those comorbidities were unacceptably low (13.2%, 8.1% and 40.4%, respectively). CONCLUSION: The considerable stroke burden was observed in urban northeast China with high proportion of stroke and related risk factors. Poorly controlled comorbidities are likely to contribute to the substantial burden in the future. Long-term primary and secondary prevention should be highlighted in urban northeast China.
