Silvestre MP, et al. – The physicians conducted this work to determine the adequacy of a high (≥12) Finnish diabetes risk (FINDRISC) score in distinguishing undiagnosed prediabetes and type 2 diabetes (T2D) in an New Zealand population of overweight and obese individuals, across a variety of ethnic groups. The FINDRISC questionnaire was considered as a feasible and efficacious screening tool to distinguish unknown prediabetes and T2D in overweight New Zealanders, particularly in Maori individuals.

Methods

• Researchers computed the adequacy of elevated FINDRISC scores in predicting prediabetes and T2D in 424 overweight adults with no prior diagnosis recruited for the PREVention of diabetes through lifestyle Interventions in Europe and Worldwide (PREVIEW) study.
• Moreover, all participants who completed the FINDRISC questionnaire during a pre–screening phase with a score of ≥12 were then screened using a 2 h oral glucose tolerance test (2h–OGTT) to distinguish undiagnosed dysglycaemia.

Results

• In this analysis, of the 424 participants, 65% (n = 280) were pre–diabetic and 7% (n = 32) had undiagnosed T2D.
• The data showed that a higher FINDRISC score was significantly correlated with prediabetes and T2D (P = 0.02).
• A significant correlation was found between ethnicity and glycaemic status (normal vs prediabetes/T2D, P = 0.02).
• They observed that increasing the FINDRISC cut–off to ≥15 resulted in a non–significant increase in the proportion of participants correctly categorized with dysglycaemia.
• In this analysis, ROC–AUC = 0.6 with sensitivity = 0.6026 (95% CI: 0.5459–0.6573) and specificity = 0.5536 (95% CI: 0.4567–0.6476).
• The obtained data indicate that isolated impaired fasting glucose (IFG) was more efficient in predicting dysglycaemia than isolated impaired glucose tolerance (IGT) .
