Global school-based childhood obesity interventions: a review

Area of Science:

• Public Health
• Pediatrics
• Health Promotion

Background:

• Childhood overweight and obesity represent a significant global public health challenge.
• School-based interventions are a primary strategy for addressing this growing concern.
• Effective strategies for childhood obesity prevention in schools require careful examination.

Purpose of the Study:

• To systematically compare and contrast school-based obesity prevention interventions implemented in the U.S. and internationally.
• To identify and highlight efficacious strategies for combating childhood obesity within school settings.

Main Methods:

• A systematic literature review was conducted across five databases.
• Inclusion criteria focused on primary research of school-based obesity prevention interventions published in English between 2002-2013, reporting outcome data.
• Interventions could include parents and target children of any age.

Main Results:

• Twenty interventions met the criteria, with ten from the U.S. and ten international.
• International interventions focused on elementary students, were less likely to target low-income populations, and less frequently implemented long-term.
• International interventions were more likely to incorporate environmental components compared to U.S. interventions.

Conclusions:

• Both U.S. and international school-based interventions successfully improved student Body Mass Index (BMI).
• Varying approaches demonstrate that a universal strategy is not required for childhood obesity intervention.
• Future interventions should integrate culturally specific strategies, environmental components, and parental involvement for sustained efficacy.
