title: [Performance of 3 diabetes screening questionnaires for a rural sample in China].
abstract: OBJECTIVE
  To evaluate 3 published questionnaires for screening diabetes for rural samples in China.
  
  
  METHODS
  Three screening questionnaires (Finnish Diabetes Risk Score, Danish Diabetes Risk Score, and Chinese Diabetes Risk Score) were selected through literature review, and were employed in a rural community sample in Wangcheng, Changsha.
  
  
  RESULTS
  Sensitivity of these risk scores was 63.72%, 56.64% and 82.30%; the specificity was 79.75%, 62.64% and 46.90%. The area under the receiver operating characteristic curve (AUC) was 0.78 (95% CI: 0.73-0.83), 0.65 (95% CI: 0.60-0.70) and 0.68 (95% CI: 0.63-0.73).
  
  
  CONCLUSIONS
  The 3 screening questionnaires show a lower validity than originally described when applied to rural samples in the study. Difference in population characteristics is a possible reason. F-DRS is better than the other two, suggesting that F-DRS is more suitable for diabetes screening in China rural areas.
