Family Shopping Basket Intervention: A Strategy to Reduce Obesity in Prepubertal Children.

Background/Objectives: The goal of childhood obesity treatment is to benefit the physical and mental health of children who suffer from it and to prevent complications, improving their quality of life and ensuring adequate development. Family-based interventions are demonstrating positive results, especially in prepubertal children. The aim of our study was to evaluate the effectiveness of a family grocery basket intervention for the treatment of childhood obesity in a Spanish primary care office. Methods: A randomized controlled trial comparing a family grocery basket intervention through the analysis of unhealthy products included in the grocery receipts that families bring to the primary care office, in comparison with the usual interventions. Results: Ninety-one children participated in the study (intervention group: n = 60, control group: n = 31). After one year of follow-up, a relevant weight loss with a decrease of ≥0.5 SDS in the z-IMC was obtained in 60.6% of the total sample. In the intervention group, there was a significant decrease in the number of unhealthy products in the family grocery basket and a lower percentage of hypertension and severe obesity than in the control group. In families in which there was a significant decrease in the consumption of unhealthy products, a higher percentage of weight loss was observed. Conclusions: Intervention in the family grocery basket through receipts is an original, simple and effective tool for family-based treatment in childhood obesity.
