Self-reported Health Literacy Among North Carolina Adults and Associations with Health Status and Chronic Health Conditions

BACKGROUND Low health literacy is a recognized contributor to health disparities. Significant proportions of the adult population, especially the underserved, have low health literacy. The purpose of this study was to examine health literacy and its associations with health status and chronic health conditions among North Carolina adults. METHODS The 2016 North Carolina Behavioral Risk Factor Surveillance System included health literacy questions that focused on accessing and understanding health information. Using these self-reported data, we estimated the prevalence of low health literacy and assessed its associations with general health status and chronic health conditions after adjusting for sociodemographic characteristics and health care access. RESULTS Overall, 4.8% of adults reported having difficulty getting health information or advice, 7.5% understanding oral information from health professionals, and 8.3% understanding written health information; 14.8% reported having difficulty with at least one of these tasks. The adjusted odds of low health literacy were moderately higher for those who had been diagnosed with the following conditions compared to those not diagnosed: heart attack, coronary heart disease, or stroke (AOR = 1.81, 95% CI=1.33, 2.47); COPD (AOR = 1.67, 95% CI = 1.19, 2.34); arthritis (AOR = 1.68, 95% CI = 1.32, 2.15); depression (AOR = 1.95, 95% CI=1.52, 2.50); and kidney disease (AOR = 1.62, 95% CI = 1.02, 2.60). LIMITATIONS All data were self-reported. CONCLUSIONS A notable segment of the North Carolina adult population has low health literacy, and those who do are particularly vulnerable to adverse health status. Targeted efforts are needed to identify strategies to improve health literacy and decrease health disparities.
