Note. BHLS = Brief Health Literacy Screen; BMI = body mass index; DNT-5 = Diabetes Numeracy Test; PRIDE, Partnering to Improve Diabetes Education; SD = standard deviation; SNS = Subjective Numeracy Scale; S-TOFHLA = Short Test of Functional Health Literacy in Adults.
One-way analysis of variance was used to compare differences in age, BMI, sex, mean hemoglobin A1C, and scores for DNT-5, SNS, BHLS, and S-TOFHLA across racial/ethnic subgroups.
Chi-square test was used to compare differences in the highest level of education completed and income across racial/ethnic subgroups.
