Abstract

Background: Sex-specific differences exist in morbidity and growth yet little is known about other nutritional outcomes in preterm very low birth-weight (VLBW) infants. This is important because providing optimal nutrition is essential to promote growth and reduce neurodevelopmental impairment.

Purpose: To determine the effect of sex on days to full enteral feedings and other nutritional outcomes.

Methods: This was a longitudinal 2-group cohort study using secondary analysis of existing data of 313 infants born ≤32 weeks gestation and weighing ≤1500 g. Information regarding nutritional outcomes was obtained from the infant's electronic medical records.

Results: While not statistically significant, male infants reached full feeds nearly 3 days later (18.1 vs 15.2; P = .89), required parenteral nutrition for nearly an additional 4 days (18.3 vs 14.1; P = .37), and had a central line for 3 days longer (19.6 vs 15.7; P = .65) than female infants. Males had higher direct bilirubin levels (P = .02), more emesis (P = .003), and more late-onset sepsis (P = .03). Birth weight for males was higher at birth but not at 6 weeks and while the slope of weight increase over the 6 weeks was higher in males (P = .04), growth velocity was similar between sexes yet tended to be higher in females.

Implications for practice and research: Nurses are essential in ensuring preterm infants in the neonatal intensive care unit receive optimal nutrition. This study supports nurses should consider sex-specific differences in nutritional outcomes among VLBW infants in precision based nutritional support.

期刊介绍： Advances in Neonatal Care takes a unique and dynamic approach to the original research and clinical practice articles it publishes. Addressing the practice challenges faced every day—caring for the 40,000-plus low-birth-weight infants in Level II and Level III NICUs each year—the journal promotes evidence-based care and improved outcomes for the tiniest patients and their families. Peer-reviewed editorial includes unique and detailed visual and teaching aids, such as Family Teaching Toolbox, Research to Practice, Cultivating Clinical Expertise, and Online Features. Each issue offers Continuing Education (CE) articles in both print and online formats.
