title: [The prevalence and status of pre-hospital treatments of risk factors among patients with stroke in China].
abstract: OBJECTIVE
  To analyze the distribution and treatment of risk factors in hospitalized stroke patients before stroke onset.
  
  
  METHODS
  This was a multi-center cross-sectional study. Patients with acute stroke were collected from 41 hospitals in 25 provinces in China from January to May in 2011.
  
  
  RESULTS
  A total of 20 570 stoke patients (13 062 men, 7 508 women) aged (63.0 ± 12.9) years were enrolled and analyzed in this study. Among them, 15 329 were first-onset stroke, and 17 052 were ischemic stroke. (1) Of all the subjects, 75.5% were with hypertension, 53.5% with elevated LDL-C, 37.3% with diabetes, and 6.5% with atrial fibrillation. 75.2% of them had two or more above risk factors and 43.0% had three or more risk factors. (2) According to the current definition, 53.3% of the first-onset stroke patients were classified as at high risk and 25.9% were classified as at low risk. Noticeably, 42.1% of the patients below 65 years old were at low risk by the same definition. (3) The awareness rate of hypertension was 70.3% in the first-onset stroke patients. However, only 20.1% of the patients reached the target of blood pressure control in the treatment. Although the awareness rate of hypertension and diabetes among recurrent stroke patients were relatively high, the treatment and control rates of these risk factors were still low. Compared with the other two risk factors, the awareness, treatment and control rates of elevated LDL-C were much lower.
  
  
  CONCLUSIONS
  Majority of the stroke patients are complicated with multiple risk factors before stroke onset, suggesting a great needs for improving the primary and secondary prevention of stroke in China. In addition, the definition for risk classification of stroke may need to be modified for subjects under 65 years old.
