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). CONCLUSION: 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.
