NIH STUDY REVEALS POTENTIAL LINK BETWEEN PREGNANCY COMPLICATIONS AND SLOWER INFANT DEVELOPMENT

DURHAM, N.C., Feb. 24, 2023 /PRNewswire/ -- Gestational diabetes and preeclampsia may be linked to slower biological development in infants, according to a new study funded by the Environmental influences on Child Health Outcomes Program (ECHO) at the National Institutes of Health.

The study found that newborns who were exposed to these two pregnancy complications were biologically younger than their chronologic gestational age—an effect that was most noticeable in female infants. The results provide an important clue about how these common pregnancy complications may affect infants and health outcomes later in childhood.

"In the future, we plan to continue our research with a larger sample of participants and investigate whether these biological changes detected at birth are linked to health outcomes later in childhood," said Carrie Breton, ScD, MPH, an ECHO Program investigator at the University of Southern California. "If so, doctors and researchers could use that knowledge to develop targeted interventions that can reduce the adverse effects of preeclampsia and gestational diabetes on children's health."

During the study, ECHO researchers collected DNA samples from 1,801 newborns from 12 ECHO cohorts across the United States. They used these samples to evaluate each infant's epigenetic age. Epigenetic age is a pattern of chemicals in the blood that reflects biological age rather than just chronological age. Researchers then compared the epigenetic age to the infant's chronological age at birth (measured in pregnancy weeks).

Dr. Breton and Christine Ladd-Acosta, PhD, an ECHO Program investigator from Johns Hopkins Bloomberg School of Public Health, led this collaborative ECHO research published in JAMA Network Open.
