What this study found
Results: Among 1,915 lunchbox observations, mean energy in lunchboxes did not differ significantly between lunchbox intervention and controls at follow-up (−118.39 kJ; 95% CI −307.08 to 70.30; p=0.22). Mean lunchbox energy from recommended foods increased by 79.21 kJ (95% CI 1.99 to 156.43; p=0.04). Percentage energy from recommended foods rose by 4.57 percentage points (95% CI −0.52 to 9.66; p=0.08). App engagement included 71% of parents aware of the intervention, 55% reporting healthier swaps, and 84% finding pushed content helpful; pushed messages ranged from 387 to 1,550 views per week…
