title: [Study on the prevalence rate of hypertension in Guangxi Hei Yi Zhuang population].
abstract: OBJECTIVE
  To study the prevalence rate of hypertension and the risk factors in Guangxi Hei Yi Zhuang population.
  
  
  METHODS
  A total of 1068 people of Hei Yi Zhuang nationality aged 20 and over were surveyed. Blood pressure, height, weight, serum lipid and apolipoprotein levels were measured ,and both body surface areas and body mass index were calculated. Results were compared with those in 933 people of Han nationality living in the same district.
  
  
  RESULTS
  The prevalence rates of hypertension in Hei Yi Zhuang population were significantly higher than that in Han population (25.2% vs. 17.3%, P < 0.001) ,as well as the isolated systolic hypertension (12.5% vs. 3.9%, P < 0.001). The mean levels of systolic pressure and pulse pressure in Hei Yi Zhuang population were significantly higher than those in Han population (125.20 +/- 18.62 vs. 121.88 +/- 15.99 mm Hg, P < 0.001 and 48.64 +/- 14.75 vs. 44.98 +/- 11.12 mm Hg, P <.001; respectively). The prevalence rate of hypertension in Hei Yi Zhuang population was positively correlated with triglyceride, sex and age whereas the prevalence rate of hypertension in Han population was positively correlated with total cholesterol, sex, age, and alcohol consumption. Rates of awareness on hypertension in Hei Yi Zhuang and Han population were 8.6% vs. 21.1% (P <.001), patients with treatment rate of established hypertension were 4.5 vs. 15.5 (P < 0.001) with the control rates as 1.9 vs. 10.6 (P < 0.001).
  
  
  CONCLUSIONS
  The prevalence rate of hypertension in Guangxi Hei Yi Zhuang population was significantly higher than that in Han ethnic group. The causes of high prevalence rate of hypertension might be ascribed to special geographical surroundings, unhealthy life style, high sodium intake, low education, and possibly genetic factors. The rates on awareness, treatment and control of hypertension were still under satisfaction.
