Study links vaginal microbiome patterns with selected psychological traits
Researchers in Italy studied 105 women of reproductive age at the University of Bologna, comparing vaginal microbes with answers to psychological questionnaires.
They found some microbiome patterns were associated with reward responsiveness, motivation and behavioral inhibition.
The vaginal microbiome can change with factors such as hormones, smoking, infections and antibiotic use, but how it relates to psychological health is not well understood.
An exploratory analysis suggested metabolites may statistically account for some of these associations, but the study does not show that microbes cause psychological traits.
The study was cross-sectional, so it captured a snapshot rather than tracking changes over time, and its participants met specific eligibility criteria.
Larger longitudinal studies are needed to see whether the patterns hold and to better understand any connection with psychological health.
A cross-sectional study of 105 women found associations between vaginal microbiome community types and selected psychological traits.
The traits included reward responsiveness, motivational drive and behavioral inhibition.
Exploratory analyses suggested that metabolites may statistically account for some of these associations.
The study was published in Scientific Reports.
The researchers said larger longitudinal studies are needed to test the findings and clarify possible links with psychological health.
