Insights
This study develops a standardized core outcome set for infant feeding interventions to combat childhood obesity. Standardized outcomes will improve the evaluation of interventions aimed at preventing obesity in young children.
Area of Science:
- Public Health
- Pediatrics
- Nutrition Science
Background:
- Childhood obesity is a global health crisis affecting 1 in 5 children.
- Infant feeding practices are key factors in the development of childhood obesity.
- Current infant feeding intervention trials lack standardized outcome reporting, hindering analysis.
Framework:
- Develop a core outcome set (COS) for infant feeding in children up to 1 year old.
- Utilize a multi-stage methodology for robust outcome set development.
- Incorporate diverse stakeholder perspectives, including health professionals, researchers, and parents.
Implementation:
- Systematic literature review to identify potential outcomes.
- Delphi technique with expert panels for outcome prioritization.
- Nominal group technique (NGT) consensus meeting for final COS agreement.
Implications:
- Standardized outcomes will enable consistent evaluation of infant feeding interventions.
- Improved synthesis of research findings will enhance childhood obesity prevention strategies.
- This core outcome set will guide future research and clinical practice in infant nutrition and obesity prevention.
Background:
Childhood obesity is a significant public health challenge that affects approximately one in five children worldwide. Infant feeding practices are implicated in the aetiology of childhood obesity. Infant feeding interventions for childhood obesity are increasingly popular but outcome reporting is inconsistent across trials. Lack of standardisation limits examination of intervention effects and mechanisms of change. The aim of the current project is to develop a core set of infant feeding outcomes for children ≤ 1 year old, to be evaluated in childhood obesity intervention trials.
Methods:
This project will use similar methodology to previous core outcome development research. An infant feeding core outcome set (COS) will be developed in four stages: (1) a systematic review of the literature, (2) discussion and clarification of outcomes in a meeting involving multiple stakeholder perspectives, (3) prioritisation of outcomes using the Delphi technique with an expert panel of stakeholders, and (4) achieving consensus on the COS using the nominal group technique (NGT) consensus meeting. An online Delphi survey will be conducted following the NGT meeting to prioritise outcomes identified in the systematic review. An NGT meeting will be conducted with groups of health professionals, non-clinician researchers, and parents of infants ≤ 1 year old, to achieve final consensus on the infant feeding COS.
Discussion:
This study aims to develop a core outcome set of infant feeding outcomes for randomised infant feeding studies to prevent childhood obesity. This research will improve examination and syntheses of the outcomes of such studies to prevent and reduce childhood obesity.
