Long-Term Health of Cesarean Babies

According to the March of Dimes, nearly a third of live births in the United States are by Cesarean section (C-section), posing increased risks of health problems such as obesity, Type 2 diabetes, asthma and allergies. Scientists suspect that the lack of exposure to the microorganisms in the mother’s vagina during birth may be the reason. Vaginal seeding by wiping a newborn’s skin, nose and mouth with the mother’s vaginal microbes can make the skin and gut microbiome of C-section infants more similar to vaginally delivered babies, but the long-term impacts on health have not been determined.
A study on mice published in the journal Cell may be the first evidence of the positive effect of vaginal seeding on metabolic health. The researchers found that mice that received fecal transplants from babies exposed to vaginal seeding had more diverse microbiomes a few weeks after the transplant. In addition, male mice that received fecal transplants from babies exposed to vaginal seeding had less abdominal fat than male mice with transplants from babies not exposed to vaginal seeding. Increased abdominal fat has been linked to increased risks of obesity, Type 2 diabetes and heart disease.
