Introduction: Health literacy (HL) is correlated with the risk of mortality and readmission during cardiac rehabilitation. However, the correlation between HL and utility-based health-related quality of life (HRQOL) scores has been poorly documented. Therefore, we examined the correlation between HL and utility-based HRQOL scores in participants undergoing cardiac rehabilitation. Methods: The data of 448 participants undergoing cardiac rehabilitation from the Kobe-Cardiac Rehabilitation Project for People Around the World (K-CREW) clinical trial were analyzed. Participants were divided into low and high HL cohorts. We used the 14-item Health Literacy Scale (HLS-14) to assess HL and the EuroQol 5-Dimension 5-Level (EQ-5D-5L) questionnaire to assess HRQOL at discharge. The utility scores of the EQ-5D-5L questionnaire were calculated. The median age was 71.0 [61.0–78.0] years, 75.7% of participants were male, and 60% had a low HL. Results: Median utility score was 0.88 [0.75–1.00]. Regarding the dimensions of the EQ-5D-5L questionnaire, more than 60% of participants responded positively to the severity level of "no problem." In the comparative analysis, the low HL cohort had a statistically significantly lower utility score than that of the high HL cohort (p-value = 0.03). The multivariate analysis revealed that the HLS-14 scores were not statistically significantly correlated with the utility scores. Conclusion: Participants with low HL had lower HRQOL in the comparative analysis. However, multivariate analysis revealed that HL was not statistically significantly correlated with utility-based HRQOL scores. Future studies should explore the influence of confounding or intermediate variables on the correlation between HL and HRQOL. [ABSTRACT FROM AUTHOR]
