Limited literacy and poor health: the role of social mobility in Germany and the United States.

The Organization for Economic Cooperation and Development (OECD) implemented the Program for the International Assessment of Adult Competencies (PIAAC) to provide policymakers with nationally representative profiles of knowledge, skills, and competencies. Results among participating countries indicate that the United States and Germany stand out as having the strongest relationship between literacy skills and self-reported health. Our analysis addresses factors that could mediate the particularly strong link between low literacy and poor health in these two countries and possible remedies for the problem. In particular, PIACC results also reveal that the United States and Germany share the most entrenched multigenerational literacy problem among the countries in the PIAAC survey. In spite of the many social differences that currently distinguish Germany and the United States, these countries share the lowest level of social mobility for education. Promoting social mobility by making higher education more accessible for those whose parents did not have the chance to access it might thus not only promote literacy and social capital, but indirectly also promote public health. Given the PIACC findings, the concept of social mobility and opportunities to dissolve the educational stratification merit more attention in public health research.
