Limited health literacy (LHL) is thought to occur at or below an eighth-grade reading level. However, health literacy not only involves reading and writing skills, but also listening and verbal communication skills and computational or numeracy skills required for such tasks as pill counting or insulin dosing. Language barriers also contribute to LHL, and the number of foreign-born, older adults in the United States who have limited English proficiency is growing (see Chapter 78, “Unique Needs of Older Immigrants”). Health literacy is also affected by the health care environment, which places a heavy burden on patients to manage their own complex disease processes and health care benefits.
