Evidence-based treatment for childhood obesity exists, yet a fundamental knowledge-to-action gap has significantly limited the uptake of recommendations into clinical practice, particularly in low-income settings. Persistence of this gap represents a large-scale public health threat, as the earliest generation of children living through the obesity epidemic now enters adulthood, they are the first in US history to have a shorter life expectancy than their parents, mainly due to rising rates of obesity-related cancers and cardiovascular disease. A central challenge in delivering recommended treatment is the intensity; ≥26 hours of face-to-face contact are necessary to achieve health benefits and risk reduction. The objective of the proposed project is to develop and test an implementation strategy that pairs primary care pediatric clinics with the municipal Parks and Recreation (P&R) centers to deliver the current treatment recommendations with high fidelity, while allowing while allowing crucial adaptations for the local and cultural context. Using the Fit Together model, the clinical partner provides standard medical treatment for pediatric obesity, while the community partner (typically parks and recreation) provides space facilitating the activity/nutrition sessions specifically for children referred from the clinic, along with their families. Fit Together will be implemented in two new communities in North Carolina, and investigators will study implementation outcomes as well as 12-month patient outcomes. A local cohort has been added in Durham, North Carolina, where their local Fit Together model has re-started their community activity program, and investigators will look at 6-month patient outcomes.
