Cultural Adaptation for Ethnic Diversity: A Review of Obesity Interventions for Preschool Children.

Obesity disproportionately affects U.S. ethnic minority preschool children, placing them at risk for obesity related co-morbidities and premature death. Effective culturally appropriate interventions are needed to improve health behaviors and reduce obesity in young high-risk minority children, while their behaviors are still developing. All known obesity intervention studies (e.g., diet and physical activity) since 2000 targeting U.S. ethnic minority preschool children were reviewed. Five electronic databases and eight published literature reviews were used to identify the studies. Intervention studies without identified ethnic minority participants were excluded. Ten obesity interventions studies met the review criteria. Published cultural adaptation guidelines were used to develop a mechanism to analyze, score, and rank the intervention adaptations. Cultural adaptations varied widely in rigor, depth, and breadth. Results indicated a relative absence of appropriately adapted obesity interventions for ethnic minority groups, suggesting a need for more rigorous cultural adaptation guidelines when designing obesity interventions for diverse ethnicities. Culturally appropriate adaptations appeared to enhance intervention relevance, effectiveness, and feasibility. The purpose of this literature review was to evaluate 1) the type and extent of cultural adaptations strategies applied to the interventions, and 2) how these adaptations related to the study outcomes.
