CHAMPAIGN, Ill. — The chronic stress of living in neighborhoods with high rates of violence and poverty alters gene activity in immune cells, according to a new study of low-income single Black mothers on the South Side of Chicago.

 The changes in stress-related gene expression reflect the body’s “hunker down” response to long-term threat, a physiological strategy for lying low and considering new actions rather than launching an immediate “fight-or-flight” response. This has implications for health outcomes in communities of color and other marginalized populations, said researchers at the University of Illinois Urbana-Champaign and collaborators at the University of Kentucky and UCLA. The researchers published the study in the journal Psychoneuroendocrinology.
