Overview
At birth, the infant's weight was measured daily to assess the adequacy of nutritional intake. This indicator can be influenced by various factors related to the mother, her pregnancy, as well as medical interventions during the pre-delivery phase, such as pre-partum maternal fluid intakes, and the subsequent feeding method chosen for the newborn infant. This study aimed at exploring the association between maternal vascular fluid loading during labor in the pre-partum period and neonatal weight loss in the first two days of life. The study focuses on infants fedded with infant formula.
This observational, retrospective, single-center study was carried out at the Amiens University Hospital Center. The participants were mothers aged 18 and older, hospitalized in the maternity ward following full-term delivery (\> 37 weeks of gestation). Data were collected through the medical records of the patient and their newborn.
The investigators hypothesize that a relationship may exist between maternal pre-partum vascular fluid loading and neonatal weight loss in the first two days of life, in infants fed with infant formula. These results could raise awareness and help adapt medical and parental approaches to neonatal weight loss.
