Insights
Behaviour change technique (BCT) taxonomies help understand childhood obesity prevention. This review found varied application and reporting of BCTs, highlighting a need for better guidance in childhood obesity interventions.
Area of Science:
- Public Health
- Behavioral Science
- Pediatrics
Background:
- Childhood obesity is a complex public health issue requiring effective prevention strategies.
- Behaviour Change Technique (BCT) taxonomies offer a framework to analyze and design interventions.
- Understanding how BCTs are applied in childhood obesity prevention is crucial for intervention development.
Purpose of the Study:
- To systematically review the application of BCT taxonomies in childhood obesity prevention interventions.
- To examine how BCT taxonomies have been used to design (prospectively) and assess (retrospectively) interventions.
- To identify challenges and inform best practices in reporting BCT application for childhood obesity prevention.
Main Methods:
- Systematic scoping review of multiple databases (Medline, Embase, PsycINFO, etc.) up to February 2021.
- Inclusion of studies evaluating behavioral childhood obesity prevention interventions for children aged 12 or under and/or their caregivers.
- Analysis of how BCT taxonomies were applied (prospectively, retrospectively, or both).
Main Results:
- 54 discrete studies were included, with 32 applying BCT taxonomies prospectively and 23 retrospectively.
- Significant variation was observed in the methods used to apply BCT taxonomies and report findings.
- A lack of detailed reporting on BCT selection was noted in studies using taxonomies prospectively.
Conclusions:
- BCT taxonomies are utilized in childhood obesity prevention, but their application and reporting vary considerably.
- There is a need for standardized methods and improved reporting guidelines for using BCT taxonomies in this field.
- Enhanced clarity in BCT application will strengthen the design and evaluation of childhood obesity prevention interventions.
Abstract:
Behaviour change technique (BCT) taxonomies provide one approach to unpack the complexity of childhood obesity prevention interventions. This scoping review sought to examine how BCT taxonomies have been applied to understand childhood obesity prevention interventions targeting children aged 12 years or under and/or their caregivers. A systematic search was conducted in Medline, Embase, PsycINFO, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, CINAHL and PROSPERO, to capture all eligible research up to February 2021. No limits were placed on country, language, publication dates, or full text availability. Eligible studies included any study design that applied a BCT taxonomy and evaluated behavioural childhood obesity prevention interventions targeting children aged 12 years or under and/or their parents or caregivers. Sixty-three records, describing 54 discrete studies were included; 32 applied a BCT taxonomy prospectively (i.e., to design interventions) and 23 retrospectively (i.e., to assess interventions), 1 study did both. There was substantial variation in the methods used to apply BCT taxonomies and to report BCT-related methods and results. There was a paucity of detail reported in how BCTs were selected in studies applying BCT taxonomies prospectively. Our review provides important insight into the application of BCT taxonomies in childhood obesity prevention and several ongoing challenges, pointing to the need for best practice reporting guidance.
