Precisión de la prueba de riesgo del ADA y la prueba de riesgo peruana como cribado para prediabetes

Introduction: Prediabetes in great majority will develop into diabetes mellitus; therefore, early detection through screening tests is important. Objective: To estimate the accuracy of the ADA Risk Test and the Peruvian Risk Test as a screening for prediabetes. Methods: Cross-sectional study of diagnostic tests. For the diagnosis of prediabetes, fasting glucose was extracted as the reference test. To evaluate the discriminative diagnostic performance, the graph of the receiver's operating characteristic curves was produced, which was presented with the area under the curve, and the sensitivity was taken into account to determine the cut-off point. Confidence intervals at 95% are calculated. We worked with a total of 441 subjects. Results: The prevalence of prediabetes was 14.29%. The cut-off point of the ADA Risk Test was 4. This had an area under the curve of 0.79 (CI95%: 0.75 – 0.83) and a sensitivity of 93.7% (CI95%: 84.5 – 98.2). While for the Peruvian Risk Test a cutoff of 2 was chosen. The area under the curve was 0.72 (CI95%: 0.67 – 0.78) and the sensitivity was 79.4 (CI95%: 67.3 – 88.5). Conclusions: The ADA Risk Test, with a cut-off point of 4, outperforms the Peruvian Risk Test as a screening method for prediabetes. If these results are confirmed in other prospective studies, its use can be recommended in areas where there is little access to laboratory analysis.
