What this trial studies

This pilot randomized controlled trial aims to evaluate the effects of donor human milk (DHM) compared to formula supplementation on the gut microbiome of full-term infants born via cesarean section. The study will also assess health outcomes related to sleep and growth, as well as maternal outcomes such as depression and breastfeeding self-efficacy. By randomizing infants requiring supplementation, the study seeks to establish causal relationships between feeding type and microbiome development, enhancing the potential for implementing DHM in clinical practice. Conducted in a postpartum hospital setting, this research aims to provide pragmatic insights into the benefits of DHM for both infants and mothers.

Who should consider this trial

Good fit: Ideal candidates are full-term infants born via cesarean section whose mothers intend to breastfeed.

Not a fit: Patients who do not intend to breastfeed or have significant congenital malformations may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve the gut health and overall well-being of infants born via cesarean section.

How similar studies have performed: While the use of donor human milk is gaining attention, this specific approach in cesarean-born infants is novel and has not been extensively tested.
