Happy Teeth for Hopi Tots: Cultural Adaptation of an Oral Health Entertainment-Education Intervention to Prevent Early Childhood Caries Among American Indian Children

Early childhood caries (ECC), or the presence of one or more decayed, missing, or filled teeth in children age 5 or younger, is the most chronic childhood disease though it is largely preventable. ECC is most prevalent among American Indian and Alaskan Native (AI/AN) children, with nearly 60% experiencing decay by the age of 3 and over 75% by the age of 5. Oral health is a significant indicator of overall well-being, health, and quality of life, and can have grave impacts on children and their families when disease is not addressed.

Dental decay in primary (baby) teeth can cause pain, damage to the permanent teeth, infection of the head and neck, and difficulty chewing. Severe decay can interfere with intellectual and social development, cause poor speech articulation, embarrassment, low self-esteem, missed days at school, and social isolation. In addition to the physical, psychosocial, and developmental toll on children and their families, treatment for ECC is costly, particularly when hospitalization and general anesthesia are required, which is often the case with severe decay. Because ECC is preventable and can progress quickly, early intervention is a key strategy in reducing its prevalence, particularly in high risk populations.

Interventions utilizing a variety of approaches to address ECC among AI/AN populations have produced mixed results, but few have explored the effect of creative cultural adaptation of oral health education materials on parental knowledge, attitudes, and behaviors regarding the oral health of their children. The use of Entertainment Education (E-E) and specific cultural adaptation of intervention materials have shown success in improving health behaviors of minority and disadvantaged populations. This project will utilize an experimental design using a convenience sample of Hopi parents/caregivers living off Tribal lands, who will be randomized into either the intervention group receiving a culturally adapted children's book celebrating tribal culture with an embedded oral health message, or the control group receiving a standard educational brochure developed by the National Institutes for Health (NIH) for AI/AN. The children's book has electronic book (eBook) and audio narration options for multi-media use and/or those with limited literacy and was illustrated and narrated by Tribal members. Formative assessment data from an ongoing NIH clinical trial involving AI mothers/caregivers and their children in the prevention of ECC (NCT04556175), including Hopi Tribal Community Advisory Board (CAB) meetings, and a review of current literature informed the development of intervention materials (children's book) for this study. The aim of this study is to test the impact of a culturally adapted oral health E-E intervention on the knowledge, attitudes and behaviors of American Indian parents/caregivers related to their child(ren)'s oral health.

The purpose of this research is to identify effective interdisciplinary avenues to reduce the incidence of ECC among AI/AN children. The objective of this study is to compare the effect of a culturally adapted Entertainment-Education intervention on AI parents' knowledge, attitudes, and behaviors pertaining to their children's oral health, to a standard educational brochure developed by the NIH for AI/AN parents.

The main outcome variables will be mean changes from baseline to follow-up in oral health knowledge, beliefs, and behaviors in the intervention group compared to the control group. Post-hoc analyses will be utilized to determine which specific outcome variables (i.e., knowledge, beliefs, or behavior) differed between the groups (primary outcomes).
