Summary

The Danish diabetes screening protocol demonstrated similar effectiveness in both Danish and Australian populations. This risk score is a valuable tool for identifying individuals at high risk of undiagnosed type 2 diabetes.

Area of Science:

  • Endocrinology
  • Public Health
  • Epidemiology

Background:

  • Type 2 diabetes screening protocols require validation across diverse populations.
  • The Danish diabetes risk score was developed for a Caucasian population in Denmark.

Purpose of the Study:

  • To evaluate the performance of the Danish diabetes screening protocol in an Australian population.
  • To compare its efficacy between Danish and Australian cohorts.

Main Methods:

  • Utilized data from the Danish Inter99 (n=6270) and Australian AusDiab (n=7079) studies.
  • Both studies included individuals aged 30-60 without known diabetes, undergoing oral glucose tolerance tests (OGTT).
  • Screening involved a Danish risk score followed by fasting plasma glucose (FPG) measurement.

Main Results:

  • Overall screening performance was comparable: Area Under Receiver Operator Characteristic (ROC) curve 0.75 (Australia) vs. 0.77 (Denmark).
  • Sensitivity was 71% (Australia) vs. 76% (Denmark); Positive Predictive Value (PPV) was 6% (Australia) vs. 9% (Denmark).
  • Specificity and the proportion requiring further testing showed minor but significant differences between populations.

Conclusions:

  • The Danish risk score is effective for screening undiagnosed diabetes in a geographically distinct Caucasian population.
  • It serves as a suitable tool for identifying individuals at high risk of type 2 diabetes.
