Nutritional Status as a Severity Predictor in Critical Pediatric Patients With COVID-19

Area of Science:

• Pediatric critical care medicine
• Infectious diseases
• Nutritional science

Background:

• Nutritional status significantly impacts children's health and disease outcomes.
• COVID-19 presents unique challenges for critically ill pediatric patients.

Purpose of the Study:

• To assess the influence of nutritional status on clinical outcomes in critically ill children with COVID-19.
• To identify specific nutritional factors associated with severe COVID-19 in pediatrics.

Main Methods:

• Observational, longitudinal, multicentric study in 36 Brazilian Pediatric Intensive Care Units (PICUs).
• Included 432 children (1 month-18 years) with confirmed COVID-19.
• Nutritional status assessed using z-scores (BMI/A, W/A, S/A); outcomes included ARDS, IMV, prolonged LOS, and mortality.

Main Results:

• Underweight children (12.5%) showed an independent association with ARDS (RR 2.12), need for IMV (RR 1.8), prolonged LOS (RR 1.5), and mortality (RR 8).
• Overweight children (17.6%) and short stature (23%) were also noted.
• The study included a significant proportion of patients under 24 months (46.3%).

Conclusions:

• Low weight in pediatric COVID-19 patients admitted to PICUs is independently associated with adverse outcomes.
• Underweight status correlates with increased risk of ARDS, IMV, prolonged hospital stay, and mortality.
• Highlights the critical role of nutritional assessment and intervention in pediatric COVID-19 critical care.
