Weight measurements and disease-specific growth charts to predict clinical outcomes in children with cerebral palsy | Praveen Goday | DMCN Spanish

Dr. Praveen Godet, pediatric gastroenterologist and nutrition expert at Nationwide Children's Hospital, presents findings from a retrospective study published in Developmental Medicine and Child Neurology, examining the predictive value of weight percentiles on disease-specific growth charts for children with moderate to severe cerebral palsy (GMFCS levels 3–5). The study analyzes data from 127 children aged 3–20 years (2016–2022), focusing on whether falling below the 20th percentile for weight on cerebral palsy-specific growth charts predicts adverse clinical outcomes. Results show that children below the 20th percentile had 122% more emergency department visits, longer ICU stays (median 12 vs. 6.5 days), and a stark mortality rate of 28.6% compared to 4.4% in those above the threshold—though the latter did not reach statistical significance. Weight percentiles remained stable over time, suggesting no spontaneous recovery and underscoring the need for early nutritional intervention. The study supports the 20th percentile as a clinically relevant marker, though it remains unclear whether low weight is a cause or a symptom of disease severity. The findings advocate for integrating these growth charts into clinical practice to guide early, targeted interventions. The episode emphasizes the limitations of standard growth curves for children with cerebral palsy due to differences in body composition, mobility, and energy expenditure. Alternative measurements like height are often unreliable due to scoliosis or limb discrepancies, making weight the most practical metric. While the 2011-developed cerebral palsy-specific growth charts have been used informally with the 20th percentile as a benchmark, this study provides empirical evidence of its clinical relevance. The author calls for further prospective research to confirm the causal relationship between nutrition and outcomes, but argues that current data already justify using the 20th percentile as a clinical target. The talk concludes with gratitude to the research team and a note that the full article is available in the January 2026 issue of the journal.
