[An epidemiology study on hypertension in the Zhuang nationality village from the Guangxi Zhuang Autonomous Region].

OBJECTIVE

To observe the risk factors and prevalence status of hypertension at the Guangxi Zhuang-rural region.

METHODS

Through cross-sectional survey, Xinlan village (Ethnic-Zhuang tribe village) in Liangqing District of Nanning was chosen as survey site. Select Zhuang-ethnic villagers (age ≥ 18 years, living time ≥ 6 months per year) as survey subjects. Questionnaire survey and examinations including blood pressure measurement, blood tests, and urine test were made by trained medical professionals. Multivariate logistic regression analysis was used to analyze the risk factors of hypertension.

RESULTS

Complete data were obtained in 2036 residents. The hypertension prevalence rate was 11.6% (237/2036) [12.5% (110/883) for male, 11.0% (127/1153) for female], adjusted prevalence rate was 10.7% (11.3% for male, 10.4% for female) based on the population of Guangxi in 2010. Hypertension awareness rate was 36.3% (86/237) , therapy rate was 22.8% (54/237) , and control rate was 11.0% (26/237) . Multivariate logistic regression analysis showed that age (OR = 1.06, 95%CI:1.05-1.08, P < 0.01), alcohol drinking habit (OR = 1.92, 95%CI:1.25-2.95, P < 0.01), high salt diet(OR = 1.48, 95%CI:1.04-2.10, P < 0.05), diabetes(OR = 7.03, 95%CI:1.94-25.44, P < 0.01), obesity(OR = 1.20, 95%CI: 1.15-1.25, P < 0.01) and hypertriglyceridemia(OR = 1.12, 95%CI:1.03-1.22, P < 0.01) were risk factors for hypertension in this cohort.

CONCLUSIONS

Prevalence rate is slightly lower in adult of the Guangxi Zhuang-rural areas than national or Guangxi Zhuang Autonomous Region levels, but hypertension awareness, therapy and control rates in this cohort are not satisfactory. Targeted strategies are needed to improve the prevention and therapy of hypertension in this region.
