Abstract
Childhood overweight and obesity are rising across the former Yugoslav states, driven by rapid nutrition transitions, changing lifestyles and ongoing socioeconomic disparities. Schools are among the few settings that can consistently reach children at scale, and recent WHO guidelines highlight their potential to promote healthier eating and more active daily routines. However, despite this policy momentum, the evidence base for school-based nutrition interventions in the region has not been systematically reviewed. This scoping review aims to synthesize peer-reviewed studies that implemented school-based nutrition interventions in Slovenia, Croatia, Bosnia and Herzegovina, Serbia, Montenegro, North Macedonia or Kosovo.
