Logistic regression for having a fasting blood test in the past 3 years

	All Adults
	NHANES 2005–2010
	OR	95% CI^c
Individual Screening Criteria^a
BMI≥25	1.40	1.25, 1.57
Age≥45	1.68	1.49, 1.90
Relative w/ DM	1.54	1.40, 1.70
Hypertension	1.67	1.48, 1.88
A1c≥5.7%	1.28	1.15, 1.42
CVD	1.23	1.00, 1.51
Each Additional Screening Criteria^b	1.51	1.45, 1.57

Model includes only screening criteria variables that were significant (p<0.05) after backwards step-wise elimination; initial model included BMI≥25, Age≥45, Relative with diabetes, non-Hispanic black or Hispanic race/ethnicity, Hypertension, HDL≤35mg/dL, A1c≥5.7%, history of CVD

Multiple criteria includes: BMI≥25, Age≥45, Relative with diabetes, Hypertension, A1c≥5.7%, CVD; OR indicates the likelihood of having a screening test in the past 3 years for the presence of any additional screening criteria (i.e., participants are 51% more likely to be screened for diabetes in the past 3 years if they have 2 vs. 1 [or 4 vs. 3] of the above screening criteria).

95% CI=Confidence Interval

Study population includes adults age ≥20 years without a previous diagnosis of diabetes
