Health Literacy and Child Health Outcomes: A Systematic Review of the Literature

To review the relationship between parent and child literacy and child health outcomes and interventions designed to improve child health outcomes for children or parents with low literacy skills.

We searched Medline and the Cumulative Index to Nursing and Allied Health Literature (CINAHL) for articles published from 1980 through 2008 and included studies that reported original data, measured literacy and >or=1 health outcome, and assessed the relationship between literacy and health outcomes. Health outcomes included health knowledge, health behaviors, use of health care resources, intermediate markers of disease status, and measures of morbidity. Two abstractors reviewed each study for inclusion. Included studies were abstracted into evidence tables and were assessed by using an 11-item quality scale.
