ABSTRACT
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.
ABSTRACT
<p><b>OBJECTIVE</b>To investigate the prevalence and distributing feature of chronic heart failure (CHF) in adult population of Xinjiang.</p><p><b>METHODS</b>Four-stage random sampling method was used to analyze the prevalence and distributing feature of self-reported congestive heart failure among different nationalities in adult (35 years and over) population of Xinjiang. Sampling was collected from 6 localities (Urumqi, Kelamayi, Fukang, Turfan Basin, Hetian, Yili Hazakh).</p><p><b>RESULTS</b>A total of 8459 adults were surveyed. The prevalence of CHF was 1.26% in this cohort. The prevalence of CHF was 0.89%, 1.11% and 2.14%(*) in Han, Uygur and Hazakh population, respectively ((*)P < 0.05 vs. Han and Uygur). The risk of CHF was higher in the males than in the females (1.61% vs. 0.93%, u = 2.79, P < 0.05). The prevalence of CHF increased in proportion with aging and was 0.29%, 0.60%, 1.32%, 2.55% and 4.10% in 35 - 44, 45 - 54, 55 - 64, 65 - 74, 75 years and over age groups, respectively. Common complications of CHF were hypertension (63.55%), coronary heart disease (42.99%), diabetes (18.69%), valvular heart disease (5.61%) and atrial fibrillation (4.67%).</p><p><b>CONCLUSION</b>The prevalence of CHF in Xinjiang was higher than the average level in China (0.9%) and was the highest in the Hazakh population.</p>
