Youth exposed to early adversity have lower tissue iron accumulation in the basal ganglia, but this is moderated by some microbiome features.

Early caregiving-related adversities exert lasting effects on the gut microbiome that are dependent on age. However, adversity-exposed youth consuming high-fiber, low-sugar diets have higher abundance of gut microorganisms that are potentially beneficial for mental health.

Preconception stress experienced by the mother, as well as prenatal and postnatal stress exert lasting impacts on children’s gut-microbiome-brain axis, with potential relevance for children’s psychiatric health.
Flash Talk, Goodman-Luskin Microbiome Center Symposium, Los Angeles, California
Caregiving adversity is associated with several differences in gut microbiome functional pathways in youth ages 6-16. Additionally, adversity significantly moderates the associations between several pathways and internalizing symptoms, as well as transdiagnostic physical symptoms (e.g. fatigue).

Caregiving adversity moderates the association between oral microbiome richness and hair cortisol levels in youth ages 6-16. The main effects of caregiving adversity on oral microbiome composition are small but significant. Associations between oral microbiome composition and internalizing symptoms are limited.

Caregiving adversity moderates curvilinear associations between age and gut microbiome composition in youth ages 1-18. Some of these microbiome characteristics are also associated with internalizing symptoms, including bacteria thought to contribute to short-chain fatty acid fermentation.

Gut microbiome composition is associated with caregiving adversity in youth. Additionally, NAcc-vmPFC resting-state Functional Connectivity (rs-FC) was quadratically associated with age. However, there was not a significant relationship between NAcc-vmPFC rs-FC and microbiome characteristics.

We found that youth with a history of early adversity (specifically, a history of adoption and/or foster care) had slightly but significantly different oral microbiomes than did youth with low adversity, and that the microbiomes of youth with early adversity were less strongly associated with cortisol. However, the oral microbiome was not significantly associated with mental health in our sample.

Our preliminary data revealed that electrogastrography has potential to be an informative signal in affective research, but data loss to artifacts was a major concern in our study design.

Salivary cortisol is positively associated with characteristics of the oral microbiome, some of which may indicate increased health risk.
