How childhood stress may speed up aging through changes in cell energy
Childhood Adversity and Biological Mechanisms of Accelerated Aging
This project looks at whether traumatic or stressful experiences in childhood change mitochondria (the cell's energy centers) and lead to faster biological aging in people who had early-life adversity.

What this research studies
You and others who experienced childhood maltreatment would be represented in a long-term study that has health information and stored biological samples collected over years. Researchers will measure mitochondrial DNA and mitochondrial function along with established markers of biological aging, and link those lab results to health behaviors like sleep, diet, and activity. Animal experiments and lab work will be used to help explain how cellular changes could produce the patterns seen in people. The team will use these combined data to see whether early stress creates lasting biological signs that raise risk for heart disease and other age-related conditions.
Who could benefit from this research
Good fit: People with documented or suspected childhood maltreatment or severe early-life stress who can provide health histories and biological samples (or are already part of the longitudinal cohort) would be the ideal candidates.
Not a fit: People without a history of childhood adversity or whose health problems are unrelated to stress-driven aging processes are unlikely to receive direct benefit from this project.
Why it matters
Potential benefit: If successful, this work could reveal biological signs and targets that help prevent or treat early aging and reduce long-term disease risk in people who experienced childhood adversity.
How similar studies have performed: Animal studies and emerging human research support a link between stress, mitochondrial changes, and aging, but tracing these effects over time in human samples is relatively new.
