(Ginsburg AS et al., Scientific Reports 2023;13:14128 [https://www.nature.com/articles/s41598-023-39773-4]) In a study funded by the Bill and Melinda Gates Foundation, investigators compared weight trajectories in the first 5 days after birth among newborns born in a low- and middle-income countries (LMIC) cohort with those used to develop NEWT. Between April 2019 and March 2020, a convenience sample […]

The Newborn Weight Tool (NeWT), developed by Dr. Ian Paul, a pediatrician and professor of pediatrics and public health sciences at Penn State College of Medicine, is enjoying a good measure of online celebrity.. The tool allows providers to compare a newborn’s weight loss against data from more than 160,000 infants. It has earned 2 million […]

The use of NEWT has been included in the Academy of Breastfeeding Medicine Clinical Protocol #3: Supplementary Feedings in the Healthy Term Breastfed Neonate, Revised 2017. In this protocol, clinicians are encouraged to utilize NEWT to determine the weight loss range for a newborn when considering the need for supplementary feedings. Download the Report (PDF)

Even though doctors often tell parents that newborns will regain weight lost after birth within a week or two, many infants take much longer to achieve this milestone, a U.S. study suggests.

Clinicians expect newborns to surpass birth weight by age 10 to 14 days, yet few studies have examined the natural history of weight change in the weeks after birth. We sought to determine the distribution of weight loss and subsequent regain during the first month, the proportion not surpassing birth weight by 14 and 21 […]

Nomograms that show hour-by-hour percentiles of weight loss during the birth hospitalization were recently developed to aid clinical care of breastfeeding newborns. The nomograms for breastfed neonates were based on a sample of 108,907 newborns delivered at 14 Kaiser Permanente medical centers in Northern California (United States). The objective of this study was to externally […]

The majority of newborns are exclusively breastfed during the birth hospitalization, and weight loss is nearly universal for these neonates. The amount of weight lost varies substantially among newborns with higher amounts of weight loss increasing risk for morbidity. No hour-by-hour newborn weight loss nomogram exists to assist in early identification of those on a […]

Data regarding delivery mode, race/ethnicity, feeding type, and weights were extracted from electronic medical records of the birth hospitalization at 14 Kaiser Permanente Northern California hospitals between 2009 and 2013. Newborns whose first feeding was formula from a cohort of 161471 healthy, term, singleton neonates born at ≥36 weeks’ gestation between 2009 and 2013 were […]

Online tool is first to help parents and pediatricians assess newborn weight loss Using weights obtained from over 100,000 Northern California babies, a new study is the first to detail the weight loss patterns of exclusively breastfed newborns. The results show that some breastfed babies lose weight faster and for a longer period than was previously […]
