ELGAN (Extremely Low Gestational Age Newborns)
The tiniest of babies making the biggest difference.
Each child enrolled in the ELGAN Study between 2002-2004 provides key information and holds an important piece of the puzzle that together will help us to learn what we can do to promote healthier and more content lives in those born very prematurely. Check out our progress over the years.
Participants were enrolled at birth and followed up until 2 years of age

ECHO Phase 2 underway!
The ELGAN ECHO Study at the University of North Carolina at Chapel Hill has been renewed by the National Institutes of Health for an additional 7 years. For more information, email julie.rollins@unc.edu.
The ELGAN Study is conducted in three regions of the country: New England, North Carolina, and the Lake Michigan Area. There are 12 research sites within these three regions.
Find the hospital in your location and contact your local study coordinator.
We Celebrate and Thank All of Our Participants
Check out stories from our participants, who have overcome huge adversities, and let’s celebrate all of their achievements during the past 21 years!


The NIH selected ELGAN, along with similar studies in the United States, to join in a study of about 50,000 children to learn about Environmental influences on Child Health Outcomes (ECHO). Read more about ECHO.

About the ELGAN ECHO Study
ELGAN researchers have followed over one thousand children born at least 3 months early between 2002 and 2004 at 14 different hospitals in five states. We assessed these premature babies at birth, two, ten, and 15 years of age. We are in the midst of collecting and analyzing data collected when study participants are 17-21 years of age.

ELGAN Investigators Awards and Accolades

Dr. Jean A. Frazier
ELGAN Site Principal Investigator at the University of Massachusetts Chan Medical School site
Dr. Frazier received the American Academy of Child and Adolescent Psychiatry (AACAP) 2023 Norbert and Charlotte Rieger Award for Scientific Achievement. This award recognizes the most outstanding scientific paper published in the Journal of the American Academy of Child and Adolescent Psychiatry (JAACAP) from July 2022 – June 2023. Our ELGAN article, “Psychiatric Outcomes, Functioning, and Participation in Extremely Low Gestational Age Newborns at Age 15 Years,” will be highlighted in the Editor’s column of JAACAP in the December 2023 issue of the Journal. Established in 1988, the award is supported by the Norbert and Charlotte Rieger Foundation.

Dr. Michael E. Msall
Site Principal Investigator at the University of Chicago ELGAN site
Dr. Msall received the 2023 C. Anderson Aldrich Award for Lifetime Achievement in Developmental and Behavioral Pediatrics. This award was given at the American Academy of Pediatrics National Conference and Exhibition Meeting in Washington DC on October 21,2023. The American Academy of Pediatrics (AAP) Section on Developmental and Behavioral Pediatrics (SODBP) sponsored the award which recognizes a physician who has made outstanding contributions to the field of developmental and behavioral pediatrics based on national leadership, extensive scholarly activity, record of mentorship, and expertise. Dr. Msalls’ expertise includes life-course outcomes, measuring function, partnerships with families, and advocacy to promote supports that optimize resiliency for children with neurodevelopmental disabilities. This award was established in 1964 to honor Dr. Aldrich, a founder of the AAP, who made substantial contributions toward understanding infant feeding.

Dr. Anisha Gerber
Anisha Gerber, a pediatrician training in the subspecialty of pediatric kidney disease at the University of North Carolina, is analyzing the relationship between advanced cellular age in placenta and teenagers’ blood pressure using data from the ELGAN-ECHO Study. Remarkably, she has found that advanced aging in placenta is predictive of higher blood pressure in male participants in the ELGAN Study, but not in female participants. For this project she was mentored by Keia Sanderson, a pediatric kidney specialist at the University of North Carolina.
