Keywords: Prediabetic state, diabetes mellitus, screening, primary prevention, Peru


Objective: To evaluate the validity of the risk test of the American Diabetes Association (ADA Test) as a screening for hyperglycemia in a sample of workers in Lima, Peru. Methods: Cross-sectional study of diagnostic tests. Secondary analysis of the data generated by the electronic health record of an occupational polyclinic, carried out in January and February 2020. The sample was made up of workers from different areas who attended for their occupational medical evaluation. Prediabetes was considered with a fasting glucose ≥ 100 mg / dl but less than 126 mg / dl. Results: 397 subjects were evaluated. The prevalence of hyperglycemia was 29% (115/397). With a cutoff ≥ 3 points, the ADA Test presented an area under the curve of 0.868, a sensitivity of 94.8%, and a specificity of 51.8%. The PPV was 44.5% and the NPV was 96.1%. Finally, the positive likelihood coefficient calculated was 1.96, and the negative was 0.101. Conclusion: The ADA test, with a 3-point cutoff, proves to be a simple pragmatic screening tool for undiagnosed cases of prediabetes. If current results are confirmed in future research, due to its simplicity, it can facilitate various initiatives aimed at introducing and expanding early prevention and management strategies based on this trial.
