Eating behaviours are different in youth with obesity and severe obesity.

The study purposes were to: (i) Investigate eating behaviours among patients in a paediatric weight management clinical practice and (ii) Compare eating behaviour phenotypes between children with severe obesity and obesity. This was a retrospective cross-sectional study using data collected during clinical encounters. Participants were included if they were 2-12 years old, had a body mass index ≥95th percentile and if a parent or guardian completed the Child Eating Behaviour Questionnaire (CEBQ). Participants (n = 149) were children with severe obesity (n = 108) and obesity (n = 41). The mean Satiety Responsiveness score was significantly lower for children with severe obesity than for children with obesity. Girls with severe obesity had significantly higher Enjoyment of Food and significantly lower Satiety Responsiveness and Slowness in Eating than girls with obesity. The findings demonstrate the potential clinical utility of the CEBQ for informing tailored treatment strategies through identifying eating behaviour phenotypes.
