How maternal health affects infant gut bacteria and growth

Official title: Vertical Microbiome Transmission: Implications for Infant Growth

Funded at Johns Hopkins University · NIH-11193959 · Data updated 2026-11-12

This study is looking at how the bacteria in a mom's gut during pregnancy can affect her baby's growth and risk of becoming overweight, especially focusing on Latino and Black children.

Who could benefit from this research

Could help

Ideal candidates for this research include infants aged 0-3 years, particularly those born via cesarean section or exposed to antibiotics, and whose mothers have varying weight statuses.

Less likely to help

Patients who are older than 3 years or those without any history of cesarean delivery or antibiotic exposure may not benefit from this research.

What this research studies

This research investigates how the gut microbiome, which is influenced by maternal health factors like weight and delivery method, affects the growth and obesity risk in infants. By analyzing data from two ongoing studies, the researchers will explore how changes in the maternal gut microbiome during pregnancy can impact the types of bacteria passed to infants. The study aims to identify specific patterns of microbiome transmission that may contribute to childhood obesity, particularly in Latino and Black children. This research will utilize advanced techniques to analyze the microbiome and its relationship with infant growth outcomes.

Why it matters

Potential benefit: If successful, this research could lead to new strategies for preventing obesity in children by understanding the role of maternal health and microbiome transmission.

How similar studies have gone: Previous research has shown promising results in understanding the link between the microbiome and obesity, suggesting that this approach could yield valuable insights.
