This paper aims to understand the blood pressure control status for hypertension patients, and discuss the relationship between social support, medication compliance and blood pressure for hypertensive patients. The survey objective was the hypertensive patients in chronic disease management system in Xinxiang city. The survey was conducted as the questionnaire survey filled by objectives. Social support rating scale and medication therapy compliance questionnaire was utilized to evaluate the patients’ social support and medication therapy compliance. 1095 patients in medication were investigated, the blood pressure of 66.6% investigated objectives was controlled at target levels (<140/90 mmHg), 70.0% investigated objectives have good medication therapy compliance; the overall social support score for hypertensive patients in medication was (40.01±6.54) points, the subjective support score, objective support score and support utilization degree score were respectively (24.43±4.61) points, (8.59±2.59) points and (7.00±2.06) points; Rank correlation coefficient of Spearman illustrated that the support utilization rating evaluation was apparently correlated to medication therapy compliance (rs=0.88, P<0.01); multivariate analysis proved that the protective factors for medication therapy compliance were the high support utilization rate (OR 1.62; 95%CI 1.19~2.05), long hypertensive duration (5~10 years: OR 2.01, 95%CI 1.42~2.73; more than 10 years: OR 1.46, 95%CI .01~1.99) and high average monthly household income (OR 2.03, 95%CI 1.45~2.69); Risk factor for blood pressure control were male (OR 0.61, 95% CI 0.47~0.79) and high hypertensive grade (OR 0.31, 95%CI 0.19~0.44); The protective factors for blood pressure control was good medication therapy compliance (OR 1.54, 95%CI 1.22~1.89), (average P<0.05). It required to build effective social support system, increase patients’ social support utilization degree, emphasized the intervention on low average monthly household incomes, male higher rate, higher hypertensive degree, and further improve the medication therapy compliance and hypertensive control rate of hypertensive patients.
