The majority of adults, 53 percent, had Intermediate
health literacy (figure 2-1).An additional 22 percent
of adults had Basic health literacy, 14 percent had
Below Basic health literacy, and 12 percent had
Proficient health literacy. The distribution of adults
among the different health literacy levels is similar,
although not identical, to the distribution of adults
among the levels of the prose, document, and quantitative scales (Kutner et al. 2005).
