Assessing implementation science outcomes for pediatric overweight and obesity interventions in Latin America and the Caribbean for children ages 6–12 years old using the RE-AIM framework: a systematic review

Childhood obesity disproportionately affects children in Latin America and the Caribbean (LAC), yet most research originates from the Global North. Limited evidence exists on available interventions and their dissemination in LAC, and reporting of external validity indicators remains insufficient. This systematic review examined family-based pediatric weight management interventions linked to healthcare providers or systems for children aged 6–12 years in LAC, using the Reach, Efficacy/Effectiveness, Adoption, Implementation, Maintenance (RE-AIM) Framework. Following PRISMA guidelines, we conducted a literature search from January 2007 to January 2024 using Ovid MEDLINE, Embase, VHL Regional Portal, Scopus, and Cochrane Library to identify eligible studies. Of the 4,216 screened records, 62 underwent full-text review, and five met the inclusion criteria. The most frequently reported RE-AIM dimensions were Reach (56%), Efficacy/Effectiveness (57%), and Implementation (43%), while Adoption (40%) and Maintenance (7%) were reported least frequently. Greater attention to external validity is essential to enhance scalability, sustainability, and dissemination of pediatric obesity interventions in LAC. Not Applicable.
