Caregiving Adversity and the Oral Microbiome

April 04, 2024

Conference Poster, Goodman-Luskin Microbiome Center Symposium, Los Angeles, California

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.

Associaitons of the Gut Microbiome with Caregiving Adversity and Internalizing Symptoms in Youth

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 Dysregulation and Reward Circuitry in Youth Exposed to Early Adversity

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.

Early Adversity is Associated with Altered Oral Microbiome Composition and a Blunted Correlation Between Cortisol and Microbiome Richness in Youth

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.

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