Today, UCLA Health reports on a recent study – published by UCLA Brain and Body Lab (BABLab) researchers – that found that youths who experienced caregiving adversity (mistreated or in foster care) had less variety and more disease-causing bacteria in their oral microbiome, compared to those who lived with their biological families. Also, for youths facing caregiving adversity, their microbes seemed less responsive to stress, suggesting that high stress levels could alter the oral microbiome towards decreased richness.

The lead author of the publication is psychology Ph.D. student Naomi Gancz and the senior author is Dr. Bridget Callaghan, an assistant professor of psychology and director of the BABLab.
