title: [Survey on the situation of normal blood pressure and prevalence and risk factors of prehypertension in Han, Uygur and Hazakh population of Xinjiang Uygur autonomous region].
abstract: OBJECTIVE
  To investigate the situation of normal blood pressure and prevalence and risk factors of prehypertension in Han, Uygur and Hazakh population ≥ 35 years old of Xinjiang Uygur autonomous region.
  
  
  METHODS
  Random samples were used to analyze the incidence of normal blood pressure and prehypertension in 3 nationalities based on data from Han, Uygur and Hazakh residents living in 7 areas (Urumqi, Ke lamayi, Fukang, the Turfan Basin locality, Hetian locality, Altay locality, and Yili Hazakh autonomous prefecture) in Xinjiang Uygur autonomous region.
  
  
  RESULTS
  A total of 16 460 subjects were selected with cluster sampling, and eligible data of 14 618 subjects were actually analyzed in Han, Uygur and Hazakh population ≥ 35 years old of Xinjiang Uygur autonomous region. Incidence of normal blood pressure was 24.9% and the prevalence of prehypertension was 34.24% (35.6% fro male and 31.5% for female, P < 0.01) in Han, Uygur and Hazakh population ≥ 35 years old in Xinjiang Uygur autonomous region. The prevalence of prehypertension was 37.34%, 32.95% and 30.62% in Han, Uygur and Hazakh population, respectively. The prevalence of prehypertension decreased with increasing age in Han and Uygur population ≥ 45 years old, and in Hazakh population ≥ 35 years old (all P < 0.05). Multiple logistic regression analysis revealed that hypertriglyceridemia ≥ 1.7 mmol/L, age ≥ 45 years old, fasting plasma glucose ≥ 7.0 mmol/L and body mass index ≥ 24.0 kg/m(2) were risk factors while the female was a protective factor of prehypertension.
  
  
  CONCLUSIONS
  The people with normal blood pressure is few and the prevalence of prehypertension is high in Han, Uygur and Hazakh population ≥ 35 years old of Xinjiang Uygur autonomous region, and it is associated with many risk factors.
