[FINDRISC as screening for detection of prediabetes and unknown type 2 diabetes]

It is fundamental to put into practice preventive and early population diagnosis actions to detect people at risk for developing Type 2 diabetes (T2D). The aim of this study was to evaluate the FINDRISC score performance as screening method to detect prediabetes and unknown T2D in municipal workers.

descriptive epidemiological and crosssectional study from 10/21 to 03/22. People suffering from a severe illness, pregnant or were already receiving drugs that modify blood glucose, were excluded. Participants completed the FINDRISC and performed an oral glucose tolerance test (OGTT). The performance of the FINDRISC was determined by calculating sensitivity, specificity, and area under the curve (AUC-ROC). The Youden's J statistic index was used to define the optimal cutoff point.

148 subjects between the ages of 18-65 were admitted, with a mean age of 42,9 ± 11,8, the 69% being males. The frequency of unknown T2D was of 3.3% (n = 5) and frequency of prediabetes was of 12.2% (n = 18). The mean of FINDRISC score was of 10.0 ± 4.8. The optimal cutoff point was ≥ 13 (sensitivity = 65.2%, Specificity = 74.4%) and the AUC-ROC 0.76 (IC95%: 0.66-0.86).

The FINDRISC proved to be an effective method for identifying people with undiagnosed T2D and prediabetes with a cut-off point of 13 in the population, place, and study period.
