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

Table 4 Performance of sets of selective screening criteria for the identification of newly detected diabetes mellitus among participants in SUNSET^c

		*Source*	Hindustani Surinamese *N = 269* AUC (bCI)	African Surinamese *N = 534* AUC (bCI)	ethnic Dutch n = 467 AUC (bCI)
1	age ≥ 45 years	DCGP	0.53 (0.50–0.61)	0.59 (0.51–0.69)	0.61 (0.54–0.68)
2	age ≥ 45 and BMI > 25 kg/m2	ADA	0.61 (0.54–0.70)	0.69 (0.62–0.78)	0.72 (0.65–0.82)
3	criteria 2, and have additional risk factors, as follows^a	ADA extended	0.69 (0.64–0.83)	0.87 (0.83–0.95)	0.80 (0.74–0.91)
4	tailored risk score^b	present study	0.70 (0.66–0.83)	0.87 (0.83–0.93)	0.78 (0.73–0.90)

^a physically inactive or 1st-degree relative with DM or high risk ethnic group (Hindustani Surinamese, i.e. South Asian) or hypertensive or reduced high density lipoprotein and/or elevated triglyceride or history of cardiovascular disease.
^b optimal screening criteria identified from multivariate analysis (ethnic groups, age, BMI, waist circumference, resting heart rate, first-degree relative with DM, hypertension, history of cardiovascular disease)
^c Persons with known DM were excluded from the analysis. Data are area under the curve (AUC) and a 'confidence interval' (bCI), based on the 2.5 and 97.5 percentiles estimated via a bootstrapping procedure [20].
DM = diabetes mellitus (fasting plasma glucose ≥ 7.0 mmol/l and/or self-reported), DCPG = Dutch College of General Practitioners, ADA = American Diabetes Association
