Insights
Children on home total parenteral nutrition (TPN) showed average intelligence but often had perceptual-motor deficits. Medical complications, not TPN itself, impacted cognitive and motor skills, with social class affecting intelligence.
Area of Science:
- Pediatric Nutrition
- Developmental Psychology
- Neurodevelopmental Disorders
Background:
- Prolonged home total parenteral nutrition (TPN) is a critical intervention for children with gastrointestinal failure.
- The long-term neurodevelopmental outcomes of children receiving home TPN require further investigation.
- Understanding factors influencing cognitive and perceptual-motor development in this population is essential.
Purpose of the Study:
- To assess intellectual and perceptual-motor functioning in children on long-term home TPN.
- To explore the relationship between TPN parameters (onset, duration) and neurodevelopmental outcomes.
- To identify medical and social factors associated with cognitive and perceptual-motor performance.
Main Methods:
- Evaluated 12 children (ages 4-7) receiving home TPN using standardized intelligence (WPPSI/WISC-R) and perceptual-motor (Beery VMI) assessments.
- Collected data on TPN onset and duration, medical complications, and socioeconomic status.
- Correlated TPN variables, medical history, and social class with cognitive and perceptual-motor test results.
Main Results:
- All children demonstrated average intellectual functioning.
- A majority exhibited deficits in perceptual-motor integration, more pronounced in older children (≥6 years).
- Home TPN duration and onset were not correlated with outcomes; however, frequent hospitalizations due to medical complications were linked to lower nonverbal intelligence and poorer perceptual-motor skills. Social class correlated with verbal and nonverbal intelligence.
Conclusions:
- Children on home TPN generally maintain average intelligence but may experience perceptual-motor challenges.
- Non-TPN-related medical complications and socioeconomic factors appear more influential on neurodevelopmental outcomes than TPN parameters.
- Further research is needed to elucidate the complex interplay of factors affecting development in children requiring long-term TPN.
Abstract:
Intellectual and perceptual-motor functioning was studied in 12 children receiving prolonged home total parenteral nutrition. Children were between the ages of 4 years 2 months and 7 years 9 months. Average duration of total parenteral nutrition was 52.25 months (SD 15.55) with an average onset of 10.67 months (SD 8.99). Total parenteral nutrition was begun for eight of the children prior to or at approximately their first birthdate. Intelligence was assessed with the Wechsler Preschool and Primary Scale of Intelligence or the Wechsler Intelligence Scale for Children--Revised. Perceptual-motor functioning was measured by the Beery Buktenica Developmental Test of Visual-Motor Integration. All children functioned within the average range of intelligence, but the majority of children evidenced some deficits in perceptual-motor performance. This was particularly true for the older children (greater than or equal to 6 years). Home total parenteral nutrition onset and duration were unrelated to outcome. Medical complications, unrelated to home total parenteral nutrition, requiring lengthy and frequent hospitalizations were highly related to nonverbal intelligence and to perceptual-motor functioning. Although unrelated to perceptual-motor deficits, social class was highly associated with verbal and nonverbal intelligence.
