中国中年人群高血压患病率及知晓率、治疗率、控制率的演变趋势

目的 了解中年人群高血压患病率及知晓率、治疗率和控制率的演变趋势。方法 利用国家“八五”(1992～1994年)和“九五”(1998年)期间年龄在35～59岁的13组可比人群资料进行分析。结果 高血压的标化患病率有小幅增加,“九五”期间达到24.0％。城市的增幅要大于乡村。高血压知晓率“九五”期间较“八五”期间增加了5.3％,达到42.6％;治疗率“八五”期间27.3％、“九五”期间为31.1％;控制率“九五”期间较“八五”期间增加了近50％,但也只有6.0％。在接受治疗的高血压患者中,不同时期的控制率分别为12.7％、19.9％,为同期整体控制率的3倍多。无论患病率、知晓率、治疗率和控制率,城乡之间、性别之间都存在差异。结论 不断上升的高血压患病率和低水平的知晓率、治疗率、控制率仍是高血压防治面临的主要现状。必须认真开展有效的措施以降低高血压的患病率,提高治疗率和控制率。

Trends in prevalence, awareness, treatment and control of hypertension in middle-aged Chinese population

OBJECTIVE: To analyze the trends in prevalence, awareness, treatment, control of hypertension among middle-aged Chinese. METHODS: The study comprised two cross-sectional surveys including urban and rural residents, manual workers, farmers and fishermen in different southern and northern parts of China. There were 13 populations under research with comparable data. 18 746 (in 1992 - 1994) and 13 504 (in 1998) participants, aged 35 through 59 years, equal number of men and women, were examined in each of the surveys, on blood pressure measurement, in 1992 - 1994 and in 1998. Hypertension was defined as systolic pressure >/= 140 mm Hg, and/or diastolic pressure >/= 90 mm Hg, and/or reported treatment with antihypertensive medications. Awareness and treatment on hypertension were assessed with standardized questions. Hypertension control was defined as measured blood pressure of less than 140/90 mm Hg. Awareness, treatment and control of hypertension were standardized according to the WHO world standard population. RESULTS: In 1998, 24.0% of participants had hypertension, an increase of 2.3% from 1992 - 1994. Prevalence of hypertension was higher in urban area (25.4%), increasing with age, and higher in men among the younger groups and lower in women among the older groups. Overall, in 1998, 42.6% were aware of their hypertensive status (increase of 5.3%), 31.3% were treated (increase of 3.8%), and the rate under control was 6.0% (increase of 2.6%). The rates of awareness, treatment and control, which tended to increase with age except those aged above 55 years, which were higher in urban areas and women compared with rural areas and men. For people with treated hypertension, the rates of those under control were ranged from 12.7% in 1992 - 1994, to 19.9% in 1998. CONCLUSION: Prevalence of hypertension was increasing in China, while the rates of control, although improving, continued to be low. This implied that effective public measures needed to be developed to enhance the awareness and rates of treatment.
