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.

Prevalence of diabetes mellitus and the performance of a risk score among Hindustani Surinamese, African Surinamese and ethnic Dutch: a cross-sectional population-based study
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.
