ObjectiveTo identify the prevalence, distribution, current status of awareness and control of hypertension in Chinese adult population.MethodsA cross-sectional survey was conducted in mainland of China in 2000 - 2001 as a part of work coordinated with InterASIA Program. A total of 15,838 nationally representative subjects aged 35 to 74 were selected with multistage cluster sampling. Measurement of blood pressure was taken for all of them with three readings in a mercuric-column sphygmomanometer after resting for five minutes. Standard structured questionnaire was used to collect their histories and treatment and prevention for hypertension. A case of hypertension was defined as any person with systolic blood pressure equal to or greater than 140 mmHg, or with diastolic blood pressure equal to or greater than 90 mmHg, or being administered with antihypertensive agents.ResultsA total of 15,838 adults aged 35 - 74 years were included in this survey. Overall, the prevalence of hypertension was 27.2%, representing 130 million persons with hypertension nationwide as estimated. Age-specific prevalence of hypertension was 10.7%, 26.8%, 38.9% and 50.2% for women and 17.4%, 28.2%, 40.7% and 47.3% for men aged 35 - 44, 45 - 54, 55 - 64 and 65 - 74 years, respectively. Among hypertensive patients, 44.7% were aware of their high blood pressure, 28.2% were taking antihypertensive medication, and 8.1% achieved their blood pressure under control (< 140/90 mm Hg). All these data indicated that percentages of awareness, treatment and control of hypertension increased by 86.2%, 92.6% and 145.4%, respectively in the past ten years, as compared with the data in 1991.ConclusionsIn the past ten years, percentages of awareness, treatment and control of hypertension in Chinese adults increased significantly, who had a relatively high prevalence of hypertension, but lower awareness and much lower percentages of treatment and control of hypertension. It is urgently needed to improve prevention, detection and treatment for hypertension in adults.
