Background: As children are at high dehydration risk, caregivers must have access to understandable and actionable educational resources. Purpose: This study assessed usability, accessibility, complexity and readability of diverse pediatric dehydration educational materials. Methods: Over-the-counter (OTC) electrolyte replacement solution labeling, internet-based OTC electrolyte replacement solution content features and YouTube™ dehydration management videos were reviewed and evaluated for adherence to health literacy guidelines. Results: Reading demands ([approximately equal to] 8th-9th grade) and text point sizes of OTC usage and instruction labels did not meet health literacy formatting guidelines. Just one electrolyte replacement solution included both English- and Spanish-language information labeling. All (n = 5) brand name electrolyte replacement solutions provided supplemental internet-based product-related resources. Unique YouTube™ dehydration management videos (n = 9), uploaded between February 16, 2015 and June 30, 2020, had view ranges from 3413 to 202 945. Discussion: The scope of pediatric childhood dehydration educational materials should be expanded upon to include multilingual options adhering to evidence-based health literacy formatting guidelines. Translation to Health Education Practice: There is need for health educators to be cognizant of communication components -- literacy levels, language, culture -- when designing health education materials and familiarize themselves with validated evidence-based tools to assess suitability of communication aids and materials.
