Preemie Girls Feed Sooner Than Boys, Study Finds

Their eating timetable affects release date from hospital

TUESDAY, May 5, 2015 (HealthDay News) -- New research supports the theory that girls born prematurely fare better than preemie boys in the first weeks of life.

The study of 2,700 premature infants found that females were able to breast-feed or bottle-feed one day earlier than males. This is an important measurement because preemies need feeding tubes if they can't suck, swallow and breathe at the same time. Infants can't go home until they can eat without a feeding tube.

On average, premature infants learned to eat independently at the equivalent of a gestational age of 36 weeks and four days, the researchers said.

But babies born by C-section tended to take longer to learn to feed by mouth than those born vaginally. And babies born with severe complications also experienced feeding delays, the study found.

"This study gives us insight into the factors that influence when an infant is likely to eat independently without complications," said senior study author Dr. Jonathan Muraskas, co-medical director of the neonatal intensive care unit at Loyola University Health System in Maywood, Ill.

The infants evaluated were born before 37 weeks of pregnancy and treated at a neonatal intensive care unit between 1978 and 2013.

The findings were published in the Journal of Neonatal-Perinatal Medicine.

"This information will allow parents and the health care team to better plan for when the infant will go home from the hospital," said Muraskas in a Loyola news release.

The majority of preterm newborns can be safely discharged three to four weeks before their due date, the researchers concluded.
