The Disparities of Hypertension Control Rate and Risk Factors among Hypertensive Residing in High-altitude and Plain in Sichuan Province

  •   Objective  To explore the disparities of hypertension control rate and its affecting factors between plateau and plain regions in Sichuan province.
      Methods  The cross-sectional study was conducted from May to September 2017. We recruited 231 subjects in Jinyang and Chenghua community health service center in Chengdu and 220 subjects in Jiulong County in Ganzi Autonomous Prefecture, Sichuan Province. Demographic characteristics, medical history, family history, lifestyle, cognitive function and medication compliance were collected using a structured questionnaire. Blood pressure and electrocardiogram were measured, and blood samples were collected among participants included in the study. Bivariate logistic regression analysis was used to investigate the affecting factors of hypertension control rate. All the statistical analyses were stratified by plateau and plain regions.
      Results  Hypertension control rate in the plain group was higher than the plateau group (19.05% vs. 8.64%). The logistic regression model showed that the control rate of hypertension was higher among the participants who were 70-80 years old than 40-50 years old in the plain group (OR=4.037, 95%CI: 1.269-12.848). Central obesity (OR=0.480, 95%CI: 0.233-0.987) and high uric acids (OR=0.994, 95%CI: 0.989-0.998) were the risk factors of control rate. In the plateau group, high medication compliance (OR=4.793, 95%CI: 1.407-16.326) and high uric acids (OR=1.008, 95%CI: 1.003-1.012) were the protective factors, and low cognitive function (OR=0.234,95%CI: 0.071-0.767) was risk factor.
      Conclusion  The control rate of hypertension in the plain is higher than that in the plateau. In the plain, the risk factors are central obesity and high uric acids, and aged 40-50 years. In the plateau, the risk factors are poor medication compliance and low cognitive function.
