THURSDAY, June 23 (HealthDay News) -- New research suggests that
the adverse effects of pre-term birth can extend well into
The latest findings, from a University of Rhode Island study
that has followed more than 200 premature infants for 21 years,
revealed that preemies grow up to be less healthy, struggle more
socially and face a greater risk of heart problems compared to
those born full-term.
One reason for this, explained study author Mary C. Sullivan,
professor of nursing at the University of Rhode Island and adjunct
professor of pediatrics at the Alpert Medical School at Brown
University, is that extremely low birth weight, repeated blood
draws, surgery and breathing issues can affect stress levels among
She pointed out these stressors produce higher levels of the
hormone cortisol, which is involved in the regulation of
metabolism, immune response and vascular tone.
Among Sullivan's findings:
The outlook isn't entirely bleak for premature infants, however.
Infants who are born too soon are often resilient and have a strong
will to succeed as they get older, the researchers found. And there
are also certain "protective factors" that can help preemies
overcome the negative issues associated with pre-term birth.
Sullivan said that supportive parents and a nurturing school
environment can mitigate the effects of premature birth.
The researchers concluded the ongoing monitoring of adults born
prematurely is justified, and would also help scientists understand
the impact of prematurity on adult health, particularly
"These findings are important for parents, nurses in the neo-natal intensive care units, teachers and staff in the schools, disability services offices in colleges and primary care providers," Sullivan said. "By identifying the issues pre-term babies face in childhood, adolescence and through adulthood, we can all be better prepared to take steps to mitigate their effects."
The study's findings were slated for presentation in September
at the 27th Congress meeting of the European Group of Pediatric
Work Physiology in Exeter, England.
Because this study is to be presented at a medical meeting, the
data and conclusions should be viewed as preliminary until
published in a peer-reviewed journal.
