[The prevalence, awareness, and control of hypertension in Xianghe county of Hebei province].

OBJECTIVE: To investigate the prevalence, awareness, control status and associated risk factors of hypertension in a rural population in Xianghe county in North China. METHODS: A total of 830 adults (aged ≥ 35) from Xianghe county were examined during July to August, 2011. Blood pressure was obtained using a standardized sphygmomanometer after a 5-minute sitting rest. Information on gender, age, education level, marital status, smoking, drinking, income, family history of hypertension and use of antihypertensive medications was obtained. RESULTS: A total of 42.4% of all subjects had hypertension. Among those with hypertension, the awareness rate was 54.8% and 50.0% of the patients were taking antihypertensive medication with the control rate of 11.9% [BP < 140/90 mm Hg (1 mm Hg = 0.133 kPa)]. Lower age and education level, lower body mass index, negative family history of hypertension were associated with poor awareness of hypertension and worse compliance with the treatment. Older age, positive family history and alcohol consumption were associated with poor blood pressure control. CONCLUSIONS: Hypertension is highly prevalent in Xianghe rural area. The awareness, treatment and control rate are all low. There is an urgent need for comprehensive strategies to improve prevention, screening, and treatment of hypertension in rural China.

[Risk factors and prevalence of cardiovascular disease of rural residents in Xianghe of Hebei province].

OBJECTIVE: To observe the risk factors and prevalence of cardiovascular disease, and predict the 10-year risk of ischemic cardiovascular disease (ICVD) of a rural residents in Xianghe of Hebei province. METHODS: Two thousand five hundred and thirty two adults ( ≥ 35 years old) were surveyed at internal medicine outpatient department of Xianghe asthma hospital in Hebei province by face-to-face interview, physical examination and biochemical test. Subjects aged 35 to 59 were also evaluated using the National 10-year Risk Assessment for ICVD. RESULTS: The prevalence of stroke and coronary heart disease was 2.2% (56/2532) and 6.9% (176/2532) respectively, the age- and sex-standardized prevalence was 1.3% and 5.9% respectively. The prevalence of hypertension, diabetes, dyslipidemia, overweight, obese and central obesity was 59.9% (1516/2532), 26.9% (682/2532), 68.5% (1735/2532), 40.9% (1038/2532), 14.8% (374/2532) and 49.5% (1254/2532) respectively, the age- and sex-standardized prevalence was 43.8%, 19.9%, 56.5%, 35.1%, 15.6%, 41.9%, respectively. Ten-year ICVD risk was higher than 10% in 14.1% (188/1336) residents aged between 35 to 59 years. CONCLUSIONS: Risk factors and prevalence of cardiovascular disease as well as 10-year risk of ICVD are high in this rural population in Xianghe of Hebei province. Intensive prevention and therapy strategies are urgently needed to attenuate the ICVD risk factors and treat ICVD in rural area of China.
