The involvement of young people in school- and community-based noncommunicable disease prevention interventions: a scoping review of designs and outcomes.

There are very few published studies on the effectiveness of interventions based on children's involvement in school- and community-based NCD prevention programmes. However, interventions with these characteristics show potential benefits, and the merits of complex multi-setting approaches should be further explored through intervention-based studies assessing their effectiveness and identifying which components contribute to the observed outcomes.
