Nutritional status and neurodevelopmental levels in infants at high risk of cerebral palsy

Abstract

ABSTRACT Importance Nutrition is associated with neurodevelopment. Infants at high risk of cerebral palsy (CP) usually suffer from undernutrition, yet the relationship between nutritional status and neurodevelopmental levels is unclear. Objective To describe the nutritional status characteristics of infants at high risk of CP, and to explore the relationship between neurodevelopmental levels and nutritional status. Methods This single‐center cross‐sectional study enrolled infants at high risk of CP, with corrected age from 0 days to 12 months. Weight and height were measured and calculated into z‐scores, which were used to classify the nutritional status based on the World Health Organization growth charts and American Society for Parenteral and Enteral Nutrition standards. The Bayley Scales of Infant and Toddler Development were used to evaluate the developmental levels of gross motor, fine motor, cognition, receptive communication, and expressive communication. Results A total of 479 infants at high risk of CP were recruited, with 43.4% classified as undernutrition. Compared to those with normal neurodevelopment, the odds of moderate and severe undernutrition were about 1.8 and 3.9 times higher in gross motor delay, 2.2 and 3.1 times higher in fine motor delay, 2.5 and 9.4 times higher in cognition delay, 2.2 and 3.9 times higher in receptive communication delay, and 3.0 and 5.6 times higher in expressive communication delay. There were significant positive correlations between nutritional status and neurodevelopmental levels (P < 0.001). Interpretation Undernutrition and neurodevelopmental delays are prevalent among infants at high risk of CP. Worse nutritional status was correlated with lower neurodevelopmental levels.
