Objective: To investigate the relationship between stroke and ankle-brachial index (ABI), pulse wave velocity (PWV) in Han, Uighur, and Kazakh populations of Xinjiang.
Methods: Data was from the investigation of cardiovascular risk survey (CRS) program among different nationalities in Xinjiang from October 2007 to March 2010. A total of 14 618 samples aged over 35 with complete data dimension were surveyed.
Results: (1) There were 633 patients with stroke, including 258 Hans (4.48%), 247 Uighurs (5.18%), and 128 Kazakhs (3.13%). The incidence of stroke was significant different in the three ethnic groups (P < 0.001). (2) Compared to the Han population, the incidence of stroke was higher (OR = 1.304) in Uighur but lower (OR = 0.794) in Kazakh. (3) PWV was significant different between stroke and non-stroke patients. After adjustment for age, body mass index, systolic blood pressure, triglyceride, total cholesterol and other risk factors, the difference remained significant, indicating that PWV (OR = 1.001, P < 0.001) might associate with the occurrence of stroke.
Conclusion: The results of this study showed that the incidence of stroke was significantly different in the three ethnic groups. PWV might associate with the occurrence of stroke.
