Combination patterns of cardiovascular risks and sequelae at different stage of hypertension in natural hypertensive population in Beijing.

To investigate combination patterns of cardiovascular risks and sequelae at different stages of hypertension, all 6176 newly or previously diagnosed hypertensives were selected from a randomized sampling surveillance data to perform a multiple correspondence analysis. Short duration hypertensives are characterized by relatively young age, less physical exercise, normal fruits and vegetable intakes, high salt diet, and nearly normal blood lipid and glucose. Middle duration hypertensives begin to pursue more physical exercise and less salt, although increasing physiological disorders are found.

[The application of a systematic-dynamic model to study the computer simulation of severe acute respiratory syndrome transmission and the impact of control measures].

Objective: (1) Building a macroscopical systematic-dynamic model of severe acute respiratory syndrome (SARS) transmission and disease control process. (2) To determine key variables on the control of SARS epidemic through computer simulation methodology, especially to analyze the effect of "screening for fever" practice during the epidemics. (3) To provide evidence for related decision-making.

[A prospective study of relationship between blood pressure and 10-year cardiovascular risk in a Chinese cohort aged 35-64 years].

Objective: To provide epidemiological data for the revision of The National Guideline for Prevention and Treatment of Hypertension through the analysis of the association between blood pressure (BP) and the risk of cardiovascular diseases (CVD) in a cohort aged 35-64 years.

Methods: A prospective study was carried out in 11 provinces from 1992 to 2002. The association between BP and CVD (CHD and stroke) was analyzed in 31728 subjects aged 35 - 64 years.

Objective: To estimate the knowledge level and clinical ability of hypertension treatment among physicians in district and community hospitals in big and moderate cities.

Methods: 43 district and community hospitals were selected by non-random sampling in Beijing and Baotou inner-Mongolia municipality. A total of 754 physicians in those hospitals were investigated, through an examination.

[Study on the influence of knowledge about hypertension and clinical management competence among physicians treating hypertensives in district and community hospitals].

Objective: To analyze the influence of knowledge about hypertension and clinical competence among physicians in district and community hospitals on management of hypertensives.

Methods: Questionnaire investigation was used in 9 district and community hospitals in Chaoyang and Haidian district, including 181 physicians and 204 patients with hypertension.
