Promoting maternal interaction improves growth, weight gain in preemies

An intervention to teach mothers of preterm infants how to interact with their babies more effectively results in better weight gain and growth for the infants, according to a study funded in part by the National Institutes of Health.
A subsequent study showed that infants who had the benefit of a major component of this intervention more rapidly developed the muscle control needed for feeding successfully from a bottle. The initial findings were published online in the Journal of Perinatology and the subsequent study in Advances in Neonatal Care.
Briefly, the intervention involved teaching mothers to recognize and respond to the subtle cues their preterm infants were hungry — far less pronounced than term infants. Mothers were also taught how to provide appropriate social and physical stimulation — such as soothing talk, and gentle massages — to spur their infants’ neurological development.
Infants born preterm often are not developed enough to feed on their own. Typically, the muscle control needed for infants to feed unassisted does not completely develop until the 34th week of pregnancy. Infants born before this time usually are fed through a nasogastric tube — a line passed through the nose and down the throat into the stomach. The study authors developed the intervention to help mothers stimulate their infant’s alertness before feeding so that the infants would be better able to feed by mouth. The intervention also sought to spur the infants’ social behaviors, such as keeping alert and looking at the mother, and neurological development, in hopes of offsetting at least some of the developmental delays often seen in preterm infants.
“Preterm infants who fail to gain sufficient weight are at a higher risk for delays and even impairments in cognitive ability and motor skills,” said Valerie Maholmes, Ph.D “We are hopeful that this intervention will prove to be an important tool in safeguarding the long-term health of an extremely vulnerable group of infants.”
