Analysis of risk factors of acute ischemic stroke for different ethnic groups in Changde.

The aim of our study was to explore the risk factors of acute ischemic stroke (AIS) for different ethnic groups in Changde city (a multi-ethnic residence inhabited mainly by Han and Tujia), Hunan Province, China.A multicenter study was performed and the demography data, etiology data and clinical features of 5338 AIS patients from 17 hospitals in Changde city were collected from January 2011 through December 2011.Student's t-test and Chi2-test were used to compare the differences between the Han and Tujia ethnic group in the AIS.In Changde, the incidence of AIS in the Tujia ethnic group was higher than that in the Han ethnic group (233.14 per million vs. 84.38 million, respectively). We found statistically significant differences between the Tujia and Han ethnicities in demographic, etiology and clinical data (eg, sex, living environment, diet, smoking, payment methods, cerebral hemorrhage and transient ischemic attack [P < .05]). In addition, compared with the Han population, the Tujia patients had a higher rate of the incidence of the anterior circulation infarction, partial anterior circulation infarction, lacunar infarction and cerebral hemorrhage.Our results indicate that lifestyle choices (eg, diet, smoking cigarettes), location, family heritage, and sex are associated with AIS and is useful for informing AIS rates and treatment for AIS.
