[Study on the relationship between hypertension management and the risk of stroke at community level].

Objective: To observe whether the community-based management for patients with hypertension can reduce the incidence of stroke.

Methods: Sample of this study included 36 863 people aged 35 years or more who came from a cohort consisting three communities from Tiantan Hospital, Puren Hospital and the Gymnasium Road Hospital in Beijing, based on the surveys on the Integrated Community Intervention Measures of Cerebro-vascular Diseases. Some patients with hypertension in this cohort were followed up and under management.

[Evaluation on a community-based intervention program among people with different risk factors of stroke].

Objective: To evaluate the effect of a long-term community-based intervention program on risk factors of stroke among people with different risk factors.

Methods: In 1987,2 geographically separated communities with 10 000 registered residents of each, were selected as either intervention or control communities in Beijing and Changsha. A cohort containing 2700 subjects at the age of 35 years or older,and free of stroke were sampled from each community.

Incidence and trends of stroke and its subtypes in China: results from three large cities.

Background And Purpose: To examine the incidence and trends of stroke and its major subtypes during the 1990s in 3 cities in China.

Methods: Stroke cases registered between 1991 to 2000 were initially identified through the stroke surveillance networks established in Beijing, Shanghai, and Changsha, and then confirmed by neurologists.

Results: The age-standardized incidence rates per 100,000 person years of overall first-ever stroke were 135.

Effects of urban community intervention on 3-year survival and recurrence after first-ever stroke.

Background And Purpose: For the past 2 decades, stroke has been a principal cause of death in China, and stroke incidence tends to increase with the increase of stroke-related risk factors. The purpose of this study was to evaluate the effects of urban community-based intervention on 3-year survival and recurrence after first-ever stroke.

Methods: Two communities with a registered population of approximately 50 000 each were selected as either intervention or control communities in Beijing during 1991 to 2000.

[Community intervention on hypertension and stroke].

Objective: To evaluate the community-based intervention on reduction of hypertension and stroke in different age groups and subtypes hypertension.

Methods: In 6 cities, 2 geographically separated communities with a registered population about 10 000 of each were selected as either intervention or control communities. A cohort containing 2 700 subjects, 35 years or older, and free of stroke were sampled from each community.
