Occupational medicine type 2 diabetes screening in Luxembourg.

Background: Type 2 diabetes, accounting for 90% of diabetes cases, is often diagnosed several years after its onset, once the complications are already present, resulting in considerable economic loss. Early and effective detection should avoid or delay the consequences it may have.
Aims: This study aims to optimize diabetes screening in the Grand Duchy of Luxembourg, among the active population on the labor market.
Methods: A cross-sectional descriptive study was conducted using a participatory survey, which included workers between the ages of 18 and 65, who have never been diagnosed with diabetes. Employees responded to the FINDRISC questionnaire and had a measurement of capillary blood glucose and an glycated hemoglobin (HbA1c) assay. The aim was to establish the level of predictability and reliability of the FINDRISC questionnaire and the correlation with capillary blood glucose and HbA1c.
Results: The univariable model of the FINDRISC score (threshold >= 10) seems to be the most suitable for the detection of dysglycemia in an occupational medicine setting.
Conclusions: Employees with a FINDRISC score <10 will be re-evaluated at the next periodical examination, those with a FINDRISC score> = 10 and a low-risk job position will be referred for follow-up to their family physicians; in addition, for those with FINDRISC score> = 10 and a high-risk job position an HbA1c assay will be performed at the occupational medicine clinic.
