Table 1. Inclusion and exclusion criteria.

	Criteria	Justification
Inclusion	Interventions with and without a control group Participants fall within the specified age range of 10-19 Digital interventions including smartphone applications, websites, text messaging, social media, email and PDA use Studies that measure a diet or PA outcome at two or more time points, and where one measurement is a baseline measure Any setting Any population of adolescents	While lack of a control increases bias, excluding these papers would result in a less comprehensive review This review is focused on adolescents This review aims to determine the effectiveness of digital interventions specifically This review is looking at interventions that effect a change, so baseline and follow-up measures are required In order to be as comprehensive as possible, inclusion is not limited by setting or population group
Exclusion	Observational studies Studies that do not report change in any dietary or PA outcomes Interventions that do not include a digital component Papers published in a language other than English Interventions that aimed to treat disordered eating	This is a review of interventions Change in diet and PA are the primary outcome measures This review aims to determine the effectiveness of digital interventions Translation resources are not available Promotion of healthy diet and adequate levels of physical activity requires different strategies to what would be appropriate for the treatment of an eating disorder
