Can a Preemie's first diet protect their heart for life?
NCT ID NCT04413994
First seen Sep 18, 2026 · Last updated Sep 18, 2026
Summary
Researchers are studying whether feeding extremely preterm infants an exclusive human milk diet, with a fortifier made from human milk, affects early signs of blood vessel aging. The trial enrolls about 200 preterm babies weighing 500 to 1250 grams at birth and compares them with term-born children. The team measures blood sugar, blood pressure, and the flexibility of the aorta at ages one, two, and five to see if the type of milk fortifier used in the newborn period makes a lasting difference for heart health.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- an exclusive human milk diet with a human milk-based fortifier
- What this could lead to
- If it works, this could show that the first diet a preterm baby receives shapes heart and blood vessel health years later, giving hospitals a clear feeding choice to lower long-term cardiovascular risk.
- What could go wrong
- The trial follows children to age five, so any differences may be small or fade over time, and feeding choices in the NICU are only one of many factors that affect later heart health. Preterm infants face many other health challenges that could outweigh the effect of diet alone.
