Data published in EBioMedicine indicated that increased maternal alpha diversity during pregnancy was associated with a reduction in internalizing symptoms in children at two years of age.
In addition, researchers reported that butyrate-producing families of bacteria called Lachnospiraceae and Ruminococcaceae were more abundant in moms of kids with “normative behavior”.
“This is the first human study to investigate the relationship between maternal fecal microbiota during pregnancy and behavioral outcomes in children,” wrote the researchers, led by Professor Peter Vuillermina from Deakin University in Australia.
“Our findings support the evidence from animal studies and suggest that there may be a developmental window during pregnancy where aspects of the maternal prenatal gut microbiota influence fetal brain development, and in turn, behavior in offspring,” they added.
Study details
Prof Vuillermina and his co-workers analyzed data from 213 mothers and 215 children participating in the Barwon Infant Study (BIS), and behavioral outcomes of the children were assessed at two years of age using the Childhood Behavior Checklist.
The data indicated an association between the alpha diversity of the mother’s fecal microbiota during the third trimester and reduced internalizing behavior in the child. However, there was no evidence of a link between prenatal alpha diversity and externalizing behaviors, said the researchers.
In addition, an association was observed between a higher maternal abundance of Lachnospiraceae and Ruminococcaceae families of the Clostridia class and normative behavior in the children.
