Abstract
Objective
To update evidence on the impact of multi-strategy nutrition education interventions
on adolescents' health and nutrition outcomes and behaviors.
Design
Systematic review of randomized controlled studies of multi-strategy interventions
encompassing nutrition education published from 2000 to 2014 guided by the Preferred
Reported Items for Systematic Reviews and Meta-analyses statement.
Setting
Secondary schools in developed countries.
Participants
Adolescents aged 10–18 years.
Main Outcome Measures
Anthropometric and dietary intake.
Analysis
Systematic search of 7,009 unduplicated articles and review of 11 studies (13 articles)
meeting inclusion criteria using qualitative comparison.
Results
Four studies reported significant changes in anthropometric measures and 9 showed
significant changes in dietary intake. Type of nutrition education varied. Components
of the interventions that showed statistically significant changes in anthropometric
and dietary intake included facilitation of the programs by school staff and teachers,
parental involvement, and using theoretical models to guide the intervention's development.
Changes in canteens, food supply, and vending machines were associated with significant
changes in dietary intake.
Conclusions and Implications
Multi-strategy interventions can have significant impacts on nutrition of adolescents
when the nutrition education is theoretically based and facilitated by school staff
in conjunction with parents and families, and includes changes to the school food
environment.
