Objective To investigate the prevalence of hypertension in the middle-age and elderly people among the Uygur and Han nationality residents in Xinjiang, and to provide the basis for further control. Methods Adopting a multistage stratified random cluster sampling approaches to survey the residents from 6 areas such as Bazhou Yanqi country and surrounding seven countries and townships, Hotan region Moyu and Hotan country town and the surrounding six townships in southern Xinjiang ; Turpan region southwest of the county town and surrounding nine rural towns in Eastern Xinjiang, the northern suburbs Bole area, the suburbs of the city, a total of 31 urban and townships Changji Hui Autonomous region of Changji city and surrounding village, Urumqi City Community, and analysis middle-age and elder Uygur and Han people older than 50-year-old suffered from hypertension in totally 8583 individuals. Results 1. The prevalence of hypertension among population over age 50 in Xinjiang was 50.55% (49.57%), the prevalence of hypertension increases with age. 2. In which, the prevalence of male hypertension were 48.85% (47.40%), 52.07% (51.67%) for females, a statistically significant difference is showed between men and women (χ2= 8.862, P <0.05). 3. the prevalence of hypertension in Uygur was 49.53 % (48.62%), and 51.93% (50.95%) in Han nationality, The hypertensive ratio of Han nationality is higher than Uygur (χ2 =4.829, P <0.05). 4.the Uygur men were 46.56% (45.40%) and women were 52.44%(51.82%), a statistically significant difference is showed between the Uygur men and women (χ2=17.103, P<0.01); the Han men were 52.35% (50.51%) and women were 51.61% (51.45%), there is no difference between the Han men and women(χ2=0.201, P>0.05). 5.the Uygur men have lower prevalence than the Han men(χ2=12.961, P<0.01); there is no difference between the Han and Uygur in females(χ2=0.317, P>0.05). 6.

Conclusions The results of this study showed that the higher prevalence of hypertension in Xinjiang. Strengthing the prevention and treatment of hypertension among high-risk population and using proper measures of intervention to decrease the prevalence of hypertension among population is necessary.
