Objectives : We sought to determine whether literacy mediates the relationship between education and glycemic control among diabetes patients. Methods : We measured educational attainment, literacy using the Short Test of Functional Health Literacy in Adults (s-TOFHLA), and glycemic control (HbA1c) in 395 diabetes patients at a U.S. public hospital. We performed path analysis to compare two competing models to explain glycemic control. The direct effects model estimated how education was related to HbA1c ; the mediational model estimated the strength of the direct relationship when the additional pathway from education to literacy to HbA1c was added. Results : Both the model with a direct effect of education on HbA1c and the model with literacy as a mediator were supported by good fit to observed data. The mediational model, however, was a significant improvement, with the additional path from literacy to HbA1c reducing the discrepancy from observed data (p
