Objective To examine the prevalence and related risk factors of stroke among urban residents in Liaoning province and to provide evidences for developing effective measures on stroke prevention and management.
Methods Using stratified random cluster sampling, we conducted a survey on stroke and its associates among 6 349 residents aged ≥ 40 years in three urban districts of two municipalities of Liaoning province between March 2018 and February 2019. The survey included questionnaire interviews, physical examinations and laboratory detections.
Results Among 5 424 residents completing the survey, 292 stroke patients were identified and the crude stroke prevalence rate was 5.4%, with a significantly higher prevalence in the male participants than in the female participants (7.2% vs. 4.4%, P < 0.001), and the standardized prevalence of stroke was 3.8% (4.8% for male and 3.4% for female participants). Multivariate logistic regression analysis revealed that male gender (odds ratio OR = 2.25, 95% confidence interval 95% CI: 1.75 – 2.97), overweight or obesity (OR = 1.35, 95% CI: 1.03 – 1.77), lack of physical exercise (OR = 1.858, 95% CI: 1.31 – 12.65), hypertension (OR = 2.84, 95% CI: 2.08 – 3.89), diabetes (OR = 1.93, 95% CI: 1.49 – 2.50), and family history of stroke (OR = 2.13, 95% CI: 1.64 – 2.78) were major risk factors for stroke.
Conclusion The prevalence of stroke was high among urban residents at ages of 40 years and above in Liaoning province, suggesting that comprehensive and effective interventions on risk factors of stroke should be promoted in the population.
