Comparing two different family-based childhood obesity treatment programmes in a medically underserved region: Effectiveness, engagement and implementation outcomes from a randomized controlled trial.

Neither intervention yielded significant improvements in child BMI z-score or parent BMI, yet both were delivered with high fidelity. Relative to iChoose, descriptive data indicated higher retention, better engagement, and lower costs for Family Connections-suggesting that a lower intensity and parent-focused programme may better fit the intended audience's context.
