This Evidence Check found digital health promotion interventions targeting parents can significantly improve parents’ and children’s dietary intake.  It aimed to identify healthy lunchbox websites and apps; how users engage with these; how effective they are as health promotion tools; and the indicators used to measure their effectiveness, reach and impact. The review found parents wanted both informative and interactive features that parents and children could engage with. While there was evidence for improved dietary intake, the evidence for increasing physical activity was mixed. The researchers note key areas for consideration in evaluating digital health interventions and recommend a range of indicators to measure reach, impact and effectiveness.
