The impact of nutritional intervention by a nutrition support team on extrauterine growth restriction in very low birth weight infants in Korea: a retrospective cohort study: Seung Yun Lee, Hye Su Hwang, Waonsun Im, Hyojoung Kim, Mi Lim Chung; Ann Clin Nutr Metab 2024;16(3):149-157.

Abstract PDF ePub: Purpose: Achieving proper weight gain through adequate nutrition is critically important in very low birth weight (VLBW) infants. Despite recent active nutritional interventions, growth restriction is still common in VLBW infants. We aimed to determine whether nutritional intervention by a nutrition support team (NST) mitigated extrauterine growth restriction (EUGR) in VLBW infants.
Methods: We retrospectively reviewed the medical records of VLBW infants admitted to Haeundae Paik Hospital between March 2010 and February 2024. EUGR was defined as a decrease in the weight-for-age-z-score>1.2 from birth to the postconceptional age of 36 weeks, using Fenton growth charts.
Results: Among the 603 enrolled VLBW infants, 434 (72.0%) were diagnosed with EUGR. When comparing the control and nutritional intervention groups, the incidence of EUGR was significantly lower in infants in the intervention group (80.6% vs. 62.8%, P<0.00). Intervention group infants started enteral feeding earlier and reached half and full enteral feeding earlier (P<0.05). In addition, intravenous protein and lipid supply started sooner, increased at a faster rate, and reached peak concentrations sooner in the intervention group (P<0.05).
Conclusion: Nutritional intervention by an NST resulted in a significant decrease in the development of EUGR in VLBW infants.

Effect of Nutritional Intervention by the Nutrition Support Team on Postnatal Growth in Preterm Infants: So Jin Yoon, Joo Hee Lim, Soon Min Lee, Sun Jung Kim, Sun Kyung Lee, Soo Min Lee; J Clin Nutr 2020;12(2):26-33. Published online December 31, 2020; DOI: https://doi.org/10.15747/jcn.2020.12.2.26

Abstract PDF ePub: Purpose: Nutritional intervention by an interdisciplinary nutrition support team (NST) can potentially improve postnatal growth outcomes in preterm infants. This study aimed to measure the growth impact of a nutritional intervention package performed by an NST in a quality improvement effort in a neonatal intensive care unit (NICU).
Methods: Fifty-two infants born below 2,000 g and admitted to NICU participated in the Quality Improvement (QI) program between March 2016 and February 2017. The nutritional intervention was applied according to newly established nutritional guidelines on parenteral and enteral nutrition, and an NST performed a weekly nutritional assessment. The Z-scores of weight, height, and head circumference were calculated according to the gestational age and sex. The clinical impact on postnatal growth was compared between the QI and pre-QI groups. The pre-QI group included 69 infants admitted in the same NICU between 2014 and 2015.
Results: The time to the initiation of enteral nutrition decreased significantly (P<0.001). Changes in weight (P=0.027), head circumference (P=0.003), Z-scores between birth, and 40 weeks postconceptional age (PCA) were significantly larger in the QI than the pre-QI group. The percentage of infants weighing below the 10th percentile at one month after birth and at 40 weeks PCA was higher in the pre-QI than the QI group.
Conclusion: The implementation of evidence-based best practices for preterm nutrition resulted in significant improvements in the growth outcomes in preterm infants.
