Objectives: The study examines whether adult literacy skills predict self-rated health status beyond educational credentials in 17 developed countries using a cross-national survey, the Programme for the International Assessment of Adult Competencies (PIAAC). Methods:
The study uses linear regression models with country-level fixed effects to predict self-rated health to account the unobserved country-level heterogeneity. A total of 73,806 respondents aged 25 to 65 were included in the analysis. Results: Although adult literacy is positively associated
with better self-rated health in general, the strength of the relationship varies across nations. The literacy-related health inequalities are less severe in countries with the higher public share of health expenditures that may better address the needs of individuals with limited cognitive
abilities. Curriculum standardization also contributes to reducing the literacy gradients in health by decreasing variations in skills obtained in school across individuals with different social origins. Conclusions: Overall, this study reveals that promoting equity in adult literacy
skills is an important way to improve a population's health. Country-level differences in the strength of the relationship between literacy and self-rated health are systematically related to between-country differences in health financing and educational systems.
