Clinical Scorecard: AAP, NASPGHAN Issue Guidance on Faltering Weight in Children
At a Glance
Category
Detail
Condition
Faltering weight (previously termed failure to thrive) in children aged 0-5 years
Key Mechanisms
Poor weight gain defined by anthropometric z scores and weight gain velocity thresholds
Target Population
Children aged 0 to 5 years in high-income countries
Care Setting
Pediatric clinical care with multidisciplinary involvement
Key Highlights
Faltering weight defined by weight-for-length or BMI-for-age below −1.65 z score, weight gain velocity below −2 z score in children under 2 years, or a decline of ≥1 z score in weight measures.
Routine diagnostic testing and endoscopy are discouraged without concerning clinical features due to low diagnostic yield and potential risks.
Nutritional interventions, including increased caloric intake, oral supplementation, and feeding therapy, are central to management.
Guideline-Based Recommendations
Diagnosis
Use standardized anthropometric z score criteria for diagnosis.
Begin evaluation with detailed history, physical exam, and feeding/developmental assessment.
Avoid routine laboratory or imaging studies in absence of concerning features.
Reserve targeted diagnostic testing for persistent faltering weight or specific clinical concerns.
Do not use socioeconomic status as a diagnostic risk factor.
Management
Increase caloric intake to improve growth outcomes.
Consider oral nutritional supplementation to enhance weight gain.
Implement feeding therapy for children with feeding difficulties.
Utilize multidisciplinary programs to support growth and development.
Monitoring & Follow-up
Monitor growth using accurate anthropometric measurements and z scores.
Integrate growth data into electronic health records for tracking.
Tailor care individually based on patient and family needs.
Risks
Avoid endoscopy as initial evaluation due to low yield and risks including anesthesia complications (4.8%) and procedure-related adverse events (1.2%).
Be cautious with unnecessary diagnostic testing given low diagnostic yield (0.8% to 14%).
Patient & Prescribing Data
Children aged 0 to 5 years with faltering weight
Oral nutritional supplementation increases weight gain (~17.8 g/day) and energy intake; feeding therapy improves growth and developmental outcomes; multidisciplinary care yields better weight gain than standard care.
Clinical Best Practices
Use standardized z score thresholds for diagnosis rather than subjective criteria.
Prioritize detailed clinical assessment before ordering diagnostic tests.
Focus on nutritional interventions as first-line management.
Reserve invasive procedures like endoscopy for persistent or specific indications.
Consider co-occurring gastrointestinal, pulmonary, neurologic, and congenital conditions based on clinical findings.
Incorporate social determinants of health in care planning without using socioeconomic status as a diagnostic criterion.
Ensure accurate anthropometric measurement and documentation.
Adopt multidisciplinary approaches to optimize growth and developmental outcomes.
