Abstract

CONTEXT:
The use of social marketing to modify lifestyle choices could be helpful in reducing youth obesity. Some or all of the 8 domains of the National Social Marketing Centre's social marketing benchmark criteria (SMBC) are often used but not always defined in intervention studies.
OBJECTIVE:
The aim of this review is to assess the effectiveness of European school-based interventions to prevent obesity relative to the inclusion of SMBC domains in the intervention.
DATA SOURCES:
The PubMed, Cochrane, and ERIC databases were used.
STUDY SELECTION:
Nonrandomized and randomized controlled trials conducted from 1990 to April 2014 in participants aged 5 to 17 years were included.
DATA EXTRACTION:
After the study selection, the 8 domains of the SMBC were assessed in each included study.
RESULTS:
Thirty-eight publications were included in the systematic review. For the meta-analysis, randomized controlled trials (RCTs) reporting body mass index or prevalence of overweight and obesity were considered. Eighteen RCTs with a total of 8681 participants included at least 5 SMBC. The meta-analysis showed a small standardized mean difference in body mass index of -0.25 (95%CI, -0.45 to -0.04) and a prevalence of overweight and obesity odds ratio of 0.72 (95%CI, 0.5-0.97).
CONCLUSION:
Current evidence indicates that the inclusion of at least 5 SMBC domains in school-based interventions could benefit efforts to prevent obesity in young people. PROSPERO registration number: CRD42014007297.
