Table 2 Relationships of health literacy with random blood glucose and HbA1c

From: Health literacy and blood glucose among Guyanese emergency department patients without diagnosed diabetes: a cross-sectional study

Logistic regression Unadjusted OR (95% CI) Adjusted model OR (95% CI)**
HbA1c ≥ 48mmol 2.0 (1.2 to 3.3), p = 0.005 2.2 (1.2 to 3.8), p = 0.007
Linear regression Unadjusted Beta (95% CI) Adjusted Model Beta (95% CI)*
RBG, mmol/l 0.28 (0.04, 0.53), p = 0.02 0.20 (-0.05, 0.46), p = 0.12
HbA1c, mmol/mol 0.61 (-0.07, 1.28), p = 0.08 0.66 (-0.04, 1.36), p = 0.07
  1. * per point increase in the Single Item Literacy Screener (SILS), where higher SILS indicates lower health literacy ; **adjusted for age, gender, BMI (body mass index, kg/m2), ethnicity, and education.
