Translating the Recommended Multicomponent Intervention for Childhood Overweight and Obesity into Practice: Implementation Challenges.

A multicomponent, family-based intervention with ≥ 26 contact hours is recommended for the treatment of childhood overweight and obesity. This intervention utilizes behavioral strategies to improve diet, physical activity, and sedentary behaviors. The evidence-based recommendations for this treatment have predominantly come from randomized trials in which the intervention is implemented by research-trained staff in academic research settings, with the intervention delivered to fairly homogeneous samples that are limited in being inclusive of those experiencing health disparities. Thus, there are challenges in implementing the recommended intervention into practice. In particular, there are implementation challenges related to providers, contact time, and settings that impact all children. Specifically, the structure of the intervention may diminish its ability to be delivered by many types of providers in different settings, limiting overall accessibility. There are implementation challenges affecting children who experience health disparities, as it is not clear how efficacious the recommended intervention is for African American or Latinx children, or children from households with low income. Several strategies to reduce identified implementation challenges, such as reducing contact time and intensity of the dietary intervention, are discussed. However, use of these strategies may reduce the effect size of the weight improvements commonly seen with the recommended intervention. Suggestions for future research regarding implementation, specifically using study designs that enhance the ability to create cost-efficient and adaptive interventions that can generalize to many different children and families, are provided.
