External validation of Finnish Diabetes Risk Score (FINDRISC) and Latin American FINDRISC for screening of undiagnosed dysglycemia: analysis in a Peruvian hospital health care workers sample.

AimsTo evaluate the external validity of Finnish diabetes risk score (FINDRISC) and Latin American FINDRISC (LAFINDRISC) for undiagnosed dysglycemia in hospital health care workers. MethodsWe carried out a cross-sectional study on health workers without a prior history of diabetes mellitus (DM). Undiagnosed dysglycemia (prediabetes or diabetes mellitus) was defined using fasting glucose and two-hour oral glucose tolerance test. LAFINDRISC is an adapted version of FINDRISC with different waist circumference cut-off points. We calculated the area under the receptor operational characteristic curve (AUROC) and explored the best cut-off point. ResultsWe included 549 participants in the analysis. The frequency of undiagnosed dysglycemia was 17.8%. The AUROC of LAFINDRISC and FINDRISC were 71.5% and 69.2%; p=0.007, respectively. The optimal cut-off for undiagnosed dysglycemiaaccording to Index Youden was [≥] 11 in LAFINDRISC (Sensitivity: 78.6%; Specificity: 51.7%) and [≥]12 in FINDRISC (Sensitivity: 70.4%; Specificity: 53.9%) ConclusionThe discriminative capacity of both questionnaires is good for the diagnosis of dysglycemia in the healthcare personnel of the Maria Auxiliadora hospital. The LAFINDRISC presented a small statistical difference, nontheless clinically similar, since there was no difference by age or sex. Further studies in the general population are required to validate these results.
