Diabetes prevalence and risk-score accuracy
Hindustani Surinamese had ~26% diabetes prevalence; a clinical risk score showed moderate-to-good AUCs (~0.74–0.80) across ethnic groups.

Diabetes prevalence and risk-score accuracy
These passages occur verbatim in the stored paper text. They support the points listed below; they do not verify every statement in the explanation.
Hindustani DM prevalence 25.6%.
Overall, Hindustani Surinamese had the highest prevalence of DM 25.6%, followed by African Surinamese 12.7% and Dutch 6.8%. T
AUC 0.74/0.80/0.78 by ethnicity.
Application of the risk score (set 4) resulted in a moderate to good diagnostic accuracy: the AUC was 0.74 (0.70–0.79) for the Hindustani Surinamese, 0.80 (0.75–0.85) for the African Surinamese, and 0.78 (0.73–0.85) for the Dutch, with a NNS of 3 among the Hindustani Surinamese, 5 among the African Surinamese, and 7 among the Dutch. Trend
What they did
Cross-sectional population sample compared known/new diabetes prevalence among Hindustani Surinamese, African Surinamese, and Dutch adults and tested screening criteria including a risk score.
What they found
Prevalence was 25.6%, 12.7%, and 6.8% respectively. Risk-score AUCs were 0.74, 0.80, and 0.78 with NNS 3, 5, and 7.
The limits
What it doesn't show
Cross-sectional Amsterdam-based sample may not generalise globally; score cut-offs trade sensitivity vs workload.
