Background Information

The first few months and years of a child’s life are essential in shaping the intestinal microbiome, which rapidly develops during this time. An individual’s intestinal microbiome reaches a relative stability by toddlerhood that generally lasts into adulthood. Hence, this early period may be critical for shaping future health and preventing the development of many diseases.

Premature infants are at increased risk of an imbalance in gut bacteria and delayed or disturbed gut colonization for many reasons, including an immature gut and immune system, increased exposure to antibiotics, and delayed feeding. They are also at increased risk of many disorders associated with gut bacteria imbalance compared to infants who are born full term.

At Inova Children’s Hospital, we are conducting a microbiome study of babies born prematurely who spend time in the neonatal intensive care unit (NICU). We follow them into early childhood to examine why and how disturbances in gut bacteria develop and how they may lead to early childhood health problems such as necrotizing enterocolitis, obesity and allergies. Using the latest technology, we hope to gain better insight into how disturbances of the microbiota are associated with disease. This knowledge is essential to enable future possible microbiota manipulation in childhood, which could help prevent disease.
