Validation of the Finnish Diabetes Risk Score (FINDRISC) questionnaire for undiagnosed type 2 diabetes screening in the Slovenian working population

• We studied undiagnosed type 2 diabetes screening in the Slovenian working population.
• Optimal FINDRISC cut-off value was 7 for men and 13 for women.
• The FINDRISC cut-off value should be substantially reduced in working-age Slovenians.

We performed a cross-sectional population-based study on 632 participants, aged 20–65, who were screened using the Finnish Diabetes Risk Score (FINDRISC) questionnaire. Optimal results for men were achieved at FINDRISC ⩾ 7 (100.0% sensitivity and 0.78 AUC) and for women at FINDRISC ⩾ 13 (60.0% sensitivity and 0.78 AUC).
