3种糖尿病筛查问卷在农村居民中应用的效果评价

Performance of 3 diabetes screening questionnaires for a rural sample in China

目的：评估不同糖尿病筛查问卷在中国农村应用的效果。方法：选择有代表性的芬兰糖尿病问卷、丹麦糖尿病问卷、中国糖尿病问卷，应用于长沙市望城县的一个农村样本，评价其筛查效果。结果：利用原始文献报告的切点，3种问卷的灵敏度分别为63．72％，56．64％，82．30％；特异度分别为79．75％，62．64％，46．90％；曲线下面积（AUC）分别为0．78（95％CI：O．73～0．83），0．65（95％CI：O．60～0．70），0．68（95％CI：0．63～0．73）。结论：3种问卷应用于中国农村人群时，其效果均低于原文献报道的水平，可能与不同的人群特征有关。芬兰问卷的筛查效果优于其他两种问卷，更适用于中国农村人群的糖尿病筛查。

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 stud~ 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.
