![]() The researchers asked mothers to recall abuse, neglect or other maltreatment they experienced during childhood, and mothers were screened for anxiety during the second trimester of pregnancy. The study investigated the consequences of maltreatment to mothers during their childhoods, anxiety while pregnant and their children's exposure to stressful life events in 450 mother-child pairs in Singapore when the children were 2 years old. And while it was known that the effects of prenatal stress on rodent microbiomes persist into adulthood, scientists did not yet know how long after birth the disturbances remain in humans, or whether they affected the next generation. ![]() ![]() Previous research in humans has shown that shortly after birth, stress experienced by the infant while in the womb and the mother's own psychological distress influence the infant microbiome. Because babies acquire their first gut microbes passing through their mother's birth canal, mothers' microbiomes form the basis of their offspring's. The study, which is published in Proceedings of the National Academy of Sciences, builds on previous research in rodents, which has shown that that prenatal stress disrupts maternal vaginal and gut microbiomes. The research is the first to document the transgenerational effects of adversity on the human gut microbiome.Ī growing body of evidence links the gut microbiome to brain and immune functioning, and according to the researchers, changes to that community of microorganisms is likely among the ways that hardship affects children's socioemotional development. ![]() The researchers found small to medium changes in the children's microbiomes. ![]()
