title: [Evaluation of effectiveness of intervention on risk factors for cerebrovascular disease in three cities of China].
abstract: OBJECTIVE
  To evaluate the effects of community intervention on risk factors of cerebrovascular disease.
  
  
  METHODS
  With cluster sampling, 2,586 and 2,723 women and men aged 35 to 74 were selected randomly as intervention cohort and control cohort, respectively, from about 300 thousand community population in Beijing, Shanghai and Changsha, during 1997 to 2000. Their blood pressure, levels of blood lipid, body mass index (BMI) were measured and status of smoking and alcohol consumption were surveyed as indices of evaluation. Health education for smoking quit, alcohol consumption restriction and reinforced treatment for diabetic and hypertensive patients were implemented in the intervention communities. And, 2,544 and 2,533 persons in the two cohorts responded three years after intervention, and then all the indices mentioned above were measure again for them.
  
  
  RESULTS
  Average reduction in systolic blood pressure by 3.21 mm Hg and serum level of total cholesterol by 0.58 mmol/L was achieved in intervention cohort after intervention, but with 0.48 mmol/L increase in triglyceride. Average blood levels of both high density lipoprotein-cholesterol (HDL-C) and glucose increased in the two cohorts after intervention, but with 0.30 mmol/L net increase of blood glucose in control cohort. There was no significant difference in average increase of HDL-C between the two cohorts. BMI increased by 0.56 in control cohort, and no significant change in intervention cohort. Proportion of smoking decreased by 5.4% in men and 2.4% in women of intervention cohort, and no change in control cohort.
  
  
  CONCLUSIONS
  Level of risk factors for cerebrovascular disease reduced significantly with community intervention.
