[Study on the epidemiology and risk factors on dysphagia after ischemic stroke in Chengdu City, China].

OBJECTIVE

To study the incidence and the risk factors of dysphagia after ischemic stroke in Chengdu City, China.

METHODS

Review was made with unified questionnaire on dysphagia after ischemic stroke in 563 patients from four hospitals, from January to December 2005. Over 20 risk factors related to dysphagia after ischemic stroke were analyzed by logistic regression.

RESULTS

The total incidence of dysphagia after ischemic stroke was 13.3% in Chengdu. Data from logistic regression analysis indicated that gender, morbidity frequency, basal nuclei, periventricular lesion, hypertension, pneumonia, hyperlipemia, cervical spondylosisi, internal carotid artherosclerosis were closely related to dysphagia after ischemic stroke,with OR values as 0.416, 0.489, 0.327, 0.454, 2.187, 2.146, 0.352, 0.242 and 0.273 respectively.

CONCLUSION

The total incidence was lower than literature published from home and abroad. Gender, morbidity frequency, basal nuclei, periventricular lesion, hypertension, pneumonia, hyperlipemia, cervical spondylosisi and internal carotid artherosclerosis seemed to be risk factors to dysphagia after ischemic stroke.
