Children with phenylketonuria (PKU) exhibit more behavioral feeding issues, including poor appetite and picky eating, compared to healthy peers. These feeding challenges necessitate careful consideration within PKU dietary management strategies.

Area of Science:

  • Pediatric Nutrition
  • Metabolic Disorders
  • Behavioral Science

Background:

  • Phenylketonuria (PKU) is a rare genetic disorder requiring strict dietary management.
  • Dietary interventions in PKU can potentially impact a child's feeding behavior and development.
  • Understanding feeding behaviors in PKU is crucial for optimizing therapeutic outcomes.

Purpose of the Study:

  • To investigate and compare behavioral feeding problems in young children with PKU versus non-PKU controls.
  • To identify specific feeding difficulties experienced by children with PKU.

Main Methods:

  • A comparative study involving 15 children diagnosed with PKU (aged 1-5 years) and a control group of non-PKU children.
  • Parental reporting and observation of feeding behaviors, appetite, food variety, and gastrointestinal symptoms.

Main Results:

  • PKU children demonstrated significantly poorer appetites (p < 0.01).
  • A more limited range of consumed foods and increased gastrointestinal issues like vomiting and constipation were reported in PKU children (p < 0.03).
  • PKU children exhibited slower feeding times, a dislike for sweet foods, and some ate separately from the family (p < 0.03).

Conclusions:

  • Young children with PKU present with a higher prevalence of behavioral feeding problems.
  • These feeding challenges, including appetite, food acceptance, and mealtime behaviors, require consideration in the management of PKU.
  • The findings underscore the importance of addressing feeding behaviors alongside dietary therapy in pediatric PKU management.
