ObjectivesThe aim of the manuscript is to provide evidence-based or expert consensus-based recommendations for growth assessment and nutritional management of preterm-born infants during the post-discharge period.MethodsThe search was conducted in Pubmed, MEDLINE, EMBASE, and Cochrane Database of Systematic Reviews using the MESH terms: infant, preterm infant, low birth weight, infant food, nutritional status, nutrients, breast feeding, infant formula, human milk, dietary supplements, vitamins, iron, vitamin D, minerals, energy intake, weaning, and baby led. Overall, 402 papers were identified and screened, from which 101 publications were included in the present position paper. In the absence of evidence, recommendations reflect the authors' combined expert opinion. Final consensus was obtained through multiple e-mail exchanges and meetings with the Committee of Nutrition of the European Society for Paediatric Gastroenterology, Hepatology, and Nutrition.ResultsContinuous growth monitoring through measurements of weight, length, and HC post-discharge is recommended to identify growth faltering (GF) or undernutrition. To prevent disproportionate growth, weight-for-length z-scores should be included in the assessment when term equivalent age is reached. Infants discharged with a significant drop in weight and length, exceeding a -2 standard deviation loss, require tailored nutritional support to address long-term growth challenges and to support recovery to normal growth rates. Breastfeeding is highly recommended for all infants when feasible. Infants needing to catch up in growth should be given supplements, such as HMF For those fed with formula, an adequate protein: energy ratio, minerals, and trace elements should be supplied to facilitate catch-up growth. The start of solid foods should coincide with the infant's neurological developmental milestones, rather than adhering strictly to a set age. Vitamin D and iron supplementation (with regular ferritin monitoring) is recommended through at least 12 months CA.ConclusionFor preterm infants, close monitoring of growth after discharge and nutritional assessment is essential to identify those at high risk for GF or undernutrition and to provide individualized nutritional support when needed. These patients should either be referred to a specialized center for pediatric nutritional care or, alternatively, their general pediatrician should receive appropriate training on the subject.
