Insights
This study developed the Baby Eating Behaviour Questionnaire (BEBQ) to measure infant appetite during milk feeding. The BEBQ identifies key appetite traits in infants, aiding in understanding susceptibility to excess weight gain.
Area of Science:
- Pediatrics
- Developmental Psychology
- Nutritional Science
Background:
- Infant appetite regulation is crucial for healthy growth.
- Existing measures do not adequately capture appetite in exclusively milk-fed infants.
- Early identification of appetite traits may help prevent future weight issues.
Purpose of the Study:
- To develop and validate the Baby Eating Behaviour Questionnaire (BEBQ) for assessing infant appetite.
- To characterize appetitive traits in infants during exclusive milk feeding.
- To provide a standardized tool for researchers and clinicians.
Main Methods:
- Adapted items from the Children's Eating Behaviour Questionnaire.
- Conducted cognitive interviews with mothers for item refinement.
- Assessed the factor structure and reliability of the 18-item BEBQ in a large twin cohort (n=2402).
Main Results:
- Principal Component Analysis identified four reliable appetite constructs: enjoyment of food, food responsiveness, slowness in eating, and satiety responsiveness.
- All constructs demonstrated good internal reliability (Cronbach's α > 0.73).
- A general appetite item correlated significantly with all identified constructs.
Conclusions:
- The Baby Eating Behaviour Questionnaire (BEBQ) is a valid and reliable measure of infant appetite.
- It is the first standardized tool to assess infant appetitive traits during milk feeding.
- The BEBQ can help identify infants at risk for developing excess weight gain.
Abstract:
The objective of this study was to develop a parent-report psychometric measure of infant appetite during the period of exclusive milk-feeding. Constructs and items for the Baby Eating Behaviour Questionnaire (BEBQ) were derived from an existing psychometric measure validated for older ages, the Children's Eating Behaviour Questionnaire, supplemented by a review of the literature on milk-feeding behaviours. Cognitive interviewing with a sample of mothers (n=10) was used to refine the questions. The factor structure of the 18-item BEBQ was assessed in infants (one per family) from the Gemini twin birth cohort (n=2402 families). Principal Component Analysis identified four distinct appetitive constructs, all of which had good internal reliability: 'enjoyment of food' (Cronbach's α=0.81), 'food responsiveness' (α=0.79), 'slowness in eating' (α=0.76), and 'satiety responsiveness' (α=0.73). A single item assessing 'general appetite' correlated with all of the constructs. The BEBQ is the first standardised measure of infant appetite designed to characterise appetitive traits that might confer susceptibility to excess weight gain.
