Insights
Preterm infants with chronic lung disease (CLD) show low vitamin A levels. Feeding practices significantly impact vitamin A levels, suggesting a link between nutrition and CLD in neonates.
Area of Science:
- Neonatology
- Nutritional Science
- Pediatric Pulmonology
Background:
- Infants with chronic lung disease (CLD) exhibit lower vitamin A levels.
- Vitamin A deficiency is a concern in preterm infants.
Purpose of the Study:
- To investigate factors influencing the association between CLD and low vitamin A levels in preterm infants.
- To assess the role of feeding practices in this relationship.
Main Methods:
- Determined vitamin A levels in preterm infants (<32 weeks gestational age) with and without CLD.
- Correlated vitamin A levels with feeding practices, mechanical ventilation, and parenteral nutrition duration.
Main Results:
- Infants with CLD had significantly lower vitamin A levels from day 21 onwards.
- Median vitamin A levels in infants with CLD were below 60% of the minimum acceptable level after day 11.
- Infants with CLD required longer mechanical ventilation and parenteral nutrition, with a strong positive correlation between these durations (r = 0.83).
- Infants with CLD received less vitamin A supplementation compared to controls.
Conclusions:
- Feeding practices appear to be a key factor explaining the association between CLD and vitamin A deficiency in preterm infants.
- Optimizing vitamin A supplementation and nutritional support is crucial for infants with CLD.
Abstract:
Infants with chronic lung disease (CLD) have been demonstrated to have low vitamin A levels. The aim of this study was to assess factors which influenced this association. Vitamin A levels of infants born at less than 32 weeks gestational age with and without CLD were determined and related to feeding practice. The infants with CLD had statistically significantly lower vitamin A levels on days 21 to 30 and days 31 to 40. From day 11 onwards, the median Vitamin A levels were less than 60% of the minimum acceptable level for a healthy child or adult. Infants with CLD required significantly longer mechanical ventilation and parenteral nutrition than controls and there was a significant positive correlation between duration of mechanical ventilation and parenteral nutrition (r = 0.83). Infants with CLD received significantly less vitamin A supplementation than the infants without CLD. Our results thus suggest that feeding practice explains the association of CLD and vitamin A deficiency in preterm infants.
