Association between health literacy and diabetes outcomes and self-management behaviors among older US adults
Methods: The sample consisted of 1063 participants who were age 55 years and older AND diagnosed with DM by self-report or through bio-marker laboratory testing. A proxy HL score was derived from four demographic variables. Logistic regressions, multiple and multivariate linear regressions were performed to test the hypotheses and the strength of the relationship between the proxy HL scores and dependent variables.
Conclusion: The novel approach for measuring HL enlisted in this study has potential for advancing our understanding of the association between HL and diabetes outcomes and self-management behaviors. To date, previous research is inconclusive, though none have analyzed data obtained from a national probability sample. This approach allows researchers the opportunity to measure HL at a population level and to contribute to the limited body of knowledge.

Analyze the relationship between diabetes biomarkers (hemoglobin A1c, two-hour glucose tolerance test, and fasting glucose) and poor health literacy using a novel imputed measure of health literacy known as the Demographic Assessment for Health Literacy or DAHL; (respondents are classified into three groups: adequate, marginal, and inadequate health literacy. We also evaluate whether DAHL status is associated with known indicators of proper diabetes self-management such as recommended physical activity requirement, diabetes education, medication adherence, regular physician follow-up, achieving target blood pressure and LDL levels. We conducted secondary analysis on two variables: (v) foot exam and (vi) eyes exam; these variables are also indicators of proper diabetes self-management behaviors by the American Diabetes Association but have been shown in previous literature to be of small association to health literacy.
