The Finnish Diabetes Risk Score (FINDRISC) is widely used for risk stratification in Type 2 diabetes prevention programmes. Estimates of ß-cell function vary widely in people without diabetes and reduced insulin secretion has been described in people at risk for diabetes. The aim of this analysis was to evaluate FINDRISC as a tool to characterize reduced ß-cell function in individuals without known diabetes.
In this population-based cohort from the Hoorn municipal registry, subjects received an oral glucose tolerance test and a meal tolerance test on separate days, in random order, within 2 weeks. One hundred and eighty-six subjects, age 41-66 years, with no known Type 2 diabetes were included. Of those, 163 (87.6%) had normal glucose metabolism and 23 (12.4%) had abnormal glucose metabolism (19 with impaired glucose metabolism; four with newly diagnosed Type 2 diabetes based on study results). Insulin sensitivity and ß-cell function (classical: insulinogenic index; ratio of areas under insulin/glucose curves; model-based: glucose sensitivity; rate sensitivity; potentiation) estimates were calculated from oral glucose tolerance test and meal tolerance test data.
FINDRISC was associated with insulin sensitivity (r = -0.41, P
