- This meta-analysis aimed to determine the effect of interventions targeting multiple modifiable health behaviors (i.e., physical activity/sedentary behaviors, nutrition/diet, sleep, substance use) on depression and anxiety in young people.
- Adolescent obesity is a powerful predictor of morbidity and mortality, yet amenable to modifiable behaviors. To accurately summarize the effects of behavioral interventions on changes in adolescent body mass index and/or weight status, we assessed existing systematic reviews for reporting transparency and methodological quality.
- To determine the effectiveness of social media-based interventions in promoting positive changes in nutrition behaviors amongst adolescents, and identify the behavior change technique(s) (BCT(s)) that were used in effective interventions.
- Many adolescents have poor diet and physical activity behaviors, which can lead to the development of noncommunicable diseases in later life. Digital platforms offer inexpensive means of delivering health interventions, but little is known about their effectiveness. This systematic review was conducted to synthesize evidence on the effectiveness of digital interventions to improve diet quality and increase physical activity in adolescents, to effective intervention components and to assess the cost-effectiveness of these interventions.
