Inadequate health literacy has been associated with poorer health behaviors and outcomes in individuals with diabetes or depression. This study was conducted to examine the associations between inadequate health literacy and behavioral and cardiometabolic parameters in individuals with type 2 diabetes and to explore whether these associations are affected by concurrent depression. The authors used cross-sectional data from a study of 343 predominantly African Americans with type 2 diabetes. Inadequate health literacy was significantly and modestly associated with diabetes knowledge (r = -0.34) but weakly associated with self-efficacy (r = 0.16) and depressive symptoms (r = 0.24). In multivariate regression models, there were no associations between health literacy and A1c, blood pressure, or body mass index or control of any of these parameters. There was no evidence that depression was an effect-modifier of the associations between health literacy and outcomes. Although inadequate health literacy was modestly associated with worse knowledge and weakly associated with self-efficacy, it was not associated with any of the cardiometabolic parameters the authors studied. Because this study showed no association between health literacy and behavioral and cardiometabolic outcomes, it is unseemly and premature to embark on trials or controlled interventions to improve health literacy for the purposes of improving patient-related outcomes in diabetes.
