OBJECTIVE: To investigate the prevalence and distribution pattern of hypertension in Xinjiang adult population. METHODS: A total of 15,061 adults at 35 years old or over were surveyed. Four-stage selected random sampling was employed to analyze the prevalence and distribution pattern of self-reported congestive hypertension in different groups of nationality, age and gender. The sampled adult population was collected from 7 localities (Urumqi, Ke lamayi, Fukang, Turfan Basin, Hetian, Altay, Yili Hazakh autonomous prefecture) in 23 municipalities and 5 autonomous counties in Xinjiang. The proportion of male to female was 50% each. RESULTS: The prevalence of hypertension was 36.21% (male: 38.70% vs female: 34.22%). The Prevalence of hypertension was 33.42%, 28.50% and 48.69% in Han, Uygur and Hazakh populations respectively. The prevalence of hypertension was higher in Hazakh than Han people (χ2=29.36, P<0.01). The males had a higher frequency of hypertension than the females (χ2=20.01, P<0.01). The risk of hypertension increased substantially with age. The analysis of multiple logistic regression revealed that age (OR=1.06), alcohol consumption, obesity (OR=3.12) and levels of triglyceride (OR=1.30) and cholesterol (OR=1.32) and serum glucose (OR=1.41) were risk factors of hypertension. The corresponding relative hazards were age, alcohol consumption, obesity and levels of triglyceride and cholesterol and serum glucose for Han; the risk factors were similar in Uygur except serum glucose. Age, obesity and levels of triglyceride were only for Hazakh. CONCLUSION: There is still a higher prevalence of hypertension in Xinjiang. The prevalence of hypertension increases substantially with age and there is difference between different nationalities.
