OBJECTIVE: To investigate the percentages of awareness, treatment and control and the prevalence of hypertension in north rural China.
METHODS: An epidemiological study was conducted by stratified cluster random sampling in March 2013 within 4 out of 20 regions in north China. At least 1 250 residents aged over 35 years were recruited and there were 625 males and 625 females from 4 villages randomly selected from each region. The risk factors for hypertension such as blood pressure (BP), height, weight and past history of illness were collected.From 4 575 valid samples, there were 2 062 males and 2 513 females.Hypertension was defined as any subject with mean systolic blood pressure ≥ 140 mmHg, diastolic blood pressure ≥ 90 mmHg or use of antihypertensive medication. All the relevant rates were standardized by gender and age group according to the figures of Third National Population Census.
RESULTS: The standardized rates of hypertension in population aged over 35 years were 41.2% in Shunyi District, Beijing, 26.0% in Yuzhong County, Gansu Province, 25.2% in Jingyu County, Jilin Province and 22.8% in Dongfeng County, Jilin Province respectively. And significant differences existed among different regions (P < 0.001). The prevalence of hypertension in males was higher than that in females. The overall rates of awareness, treatment, control and control under treatment were 46.9%, 30.5%, 12.8% and 41.5% respectively in males versus 64.2%, 48.9%, 20.4% and 38.4% respectively in females. These rates were significantly higher in people with a family history of hypertension than those without one (P < 0.05). The prevalence of hypertension and the rates of awareness, treatment increased with the increase of BMI (P < 0.05) other than the rates of control and control with drugs.
CONCLUSION: The prevalence of hypertension was of great difference between different rural areas in north China. The rates of awareness, treatment and control have remained at a low level.
