Childhood Trauma and Aging: How Early Stress Shapes Midlife Health
Official title: Childhood Maltreatment, Accelerated Biological Aging and Cognitive Function at Midlife: A Biopsychosocial Study Across the Lifespan
Funded at Univ of North Carolina Chapel Hill · NIH-11449548 · Data updated 2026-11-12
This project looks at how childhood abuse and stress may speed up aging in the body and affect thinking skills by midlife, using data from a large national study.

Who could benefit from this research
✓Could help
Individuals with a history of childhood maltreatment or early-life trauma who are now in midlife or older and may be at risk for accelerated aging or cognitive changes.
✕Less likely to help
People without a history of childhood maltreatment or current cognitive concerns may have limited direct benefit from this research.
What this research studies
Researchers will explore whether experiences of childhood maltreatment lead to faster aging at the cellular level and to changes in memory and thinking in midlife. The study will examine psychosocial and inflammatory pathways across the lifespan and consider differences between sexes. Using existing longitudinal data, the team will analyze how early-life stress influences later inflammation, aging markers, and cognitive outcomes, with a focus on potential mechanisms and risk factors. The work aims to illuminate how early adversity could contribute to risks for Alzheimer’s disease and related dementias later in life.
Why it matters
Potential benefit: If successful, findings could inform early interventions to reduce long-term aging and cognitive decline after childhood trauma.
How similar studies have gone: Prior studies have linked early adversity with later aging and cognitive changes, but this project may reveal specific mechanisms and sex differences.
