A Personalized Approach to Determining the Caloric Needs of Children with Prader-Willi Syndrome Treated with Growth...

Area of Science:

• Pediatrics
• Genetics
• Endocrinology

Background:

• Prader-Willi Syndrome (PWS) is a genetic disorder frequently causing obesity.
• Children with PWS typically require 20-40% fewer calories than healthy children.
• Growth hormone (GH) treatment, approved in 2000, impacts body composition and energy needs in PWS.

Purpose of the Study:

• To analyze caloric intake in children with PWS undergoing GH treatment.
• To compare actual caloric intake with recommended intake for healthy children.
• To inform revised dietary guidelines for children with PWS on GH therapy.

Main Methods:

• Retrospective cross-sectional study of 25 children (6 months to 12 years) with PWS on GH treatment.
• Caloric intake assessed via parent-recorded dietary data.
• Comparison with age, sex, height, weight, and activity-adjusted recommendations for healthy children.

Main Results:

• Mean daily energy intake was 1208 ± 186 kcal/d.
• This intake represented 96.83% ± 18.66 of recommended calories for healthy children.
• Caloric intake in PWS children on GH was similar to healthy children's recommendations.

Conclusions:

• Children with PWS receiving growth hormone treatment may not require significantly fewer calories than healthy children.
• Current dietary recommendations for children with PWS may need re-evaluation.
• Further research is warranted to refine nutritional management for PWS patients on GH therapy.
