1 Background Fiji has a high prevalence of childhood overweight and obesity (World Obesity Federation 2019, 2023), with rates expected to rise annually by 4.3% between 2020 and 2035. Although nearly 90% of children in Fiji meet physical activity recommendations, only two thirds meet the sedentary recreational screen time (ST) recommendations, and only half meet both the physical activity (PA) and ST recommendations (Ryan et al. 2025).
