Awareness, Treatment, and Control Rates of Hypertension in Adults Aged 35–75 Years in Three Provinces of Central China

Abstract

Abstract Background To describe the status of hypertension awareness, treatment, and control rates and their relationships with individual characteristics in Henan, Hubei, and Hunan provinces in central China, and to describe the patterns of antihypertensive drug use in this region. Methods The awareness, treatment, and control rates of hypertension in this area were identified through analysis of the data from China Patient-Centered Evaluative Assessment of Cardiac Events (PEACE) Million Persons Project in three provinces (Henan, Hubei, and Hunan) of central China. The patterns of antihypertensive drug use were also examined. The mixed model was used to analyze the relationship between the awareness, treatment, and control rates and individual characteristics at the patient level. Results A total of 268,461 subjects were enrolled with 37.9% male and an average age of (56.3 ± 9.7) years. Among them, 129,099 (48.1%) had hypertension, of which 49.5% were aware of hypertension, 42.9% received antihypertensive drugs, and 11.5% had blood pressure under control. Calcium channel antagonists (54.6%) were the most widely used among all antihypertensive drugs. Of the patients whose blood pressure were not controlled, 25,482 patients (86.4%) took only one antihypertensive drug. In addition, the rate of awareness, treatment, and control of hypertension varied significantly among different populations: the rates were higher among the older, as well as among subjects with higher annual family income, higher educational status, and history of myocardial infarction, stroke, and diabetes (all P < 0.05). Conclusions The awareness, treatment, and control rates of hypertension in adult patients of central China require further improvement. Meanwhile the proportion of combination drug therapy is low.
