The Effect of Interventions That Target Multiple Modifiable Health Behaviors on Symptoms of Anxiety and Depression in Young People: A Meta-Analysis of Randomized Controlled Trials.

Abstract

PURPOSE: 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. METHODS: A search of electronic databases from inception until May 2020 was conducted. Randomized controlled trials (RCTs) that explicitly targeted at least two modifiable health behaviors, measured anxiety or depression at baseline and after intervention using a validated instrument, and included participants with an average age between 12 and 25 years were included. The effect of interventions was synthesized using random effects meta-analysis. ..
