Objective: To understand the effects of standardized community-based management of hypertension in urban and rural areas in China and related influencing factors.
Methods: The study subjects were the hypertension patients aged ≥35 years who were recruited in 2011 from the participants of 2010 national chronic and non-communicable disease surveillance project. The hypertension patients were diagnosed in community health centers or higher level hospitals and included in community based hypertension management project. By face-to-face questionnaire survey and health examination, the information of the subjects' demographic characteristics, risk factors, complications, involvement in community-based management of hypertension, anti-hypertension treatment, blood pressure, body height, waistline and body weight were collected. In this study, Rao-Scott χ(2) test was used to compare the variations among sub-groups. Taylor series linearization method was used to estimate the prevalence rate. The complex sampling and unconditional multivariate logistics regression analysis was conducted to identify the influencing factors for the control of hypertension.
Results: A total of 5 120 subjects were recruited in the analysis. The proportion of those receiving management for more than two years was 36.57%, and it was higher in urban area(44.56%)than in rural area(31.79%, P<0.05); In the past 12 months, 6.17% and 14.46% of the patients received no blood pressure measurement and drug therapy advice respectively, but there were no significant differences between urban group and rural group(P>0.05); In the past 12 months, the proportions of the patients receiving diet and physical activity advice were 84.25% and 84.90% respectively, and the proportions were higher in urban group than in rural group(P<0.05); In the past 12 months, the proportions of the subjects receiving tobacco and alcohol use advice were 78.41% and 77.80% respectively, and the proportions were higher in rural group than in urban group(P<0.05). In urban area, the subjects receiving standardized management had lower SBP(142.79±17.39)mmHg, lower DBP(84.26±9.49)mmHg and higher blood pressure control rate(49.77%)than those receiving no standardized management(P<0.05); while in rural area, no difference was found in BP control between the patients receiving and receiving no standardized management(P>0.05). In urban area, the influencing factors for BP control among the subjects receiving community based management were educational level, annual income, body weight, hypertension management mode, times of receiving BP measurement, times of receiving antihypertensive medicine advice and receiving physical activity advice; while in rural area, the influencing factors for BP control among the subjects receiving community based management were annual income, body weight, family history of hypertension, antihypertensive medicine awareness, times of receiving antihypertensive medicine advice and receiving diet advice.
Conclusion: The effects of community-based standardized management of hypertension were better in urban area than in rural area, and the quality of the services of community-based hypertension management was lower in rural area than in urban area.
