Social stress, cellular aging, and early birth risk in Black women
Epigenetic aging, social factors, and preterm birth among Black women
This project looks at whether life stress and a DNA-based measure of cellular aging are linked to having a baby before 37 weeks among Black pregnant women.

What this research studies
This work follows Black women through pregnancy, collecting blood samples and information about life stress and social conditions. Researchers will measure a DNA-based "epigenetic" age, including a sensitive ribosomal DNA clock, to see if some women's cells show signs of faster aging. They will compare these biological aging measures with pregnancy outcomes to see if faster cellular aging is associated with early birth. The study combines laboratory tests on blood with surveys about stress and living situations to better understand causes of higher preterm birth risk.
Who could benefit from this research
Good fit: Pregnant Black women who can provide blood samples and answer questions about social stressors would be the ideal participants for this work.
Not a fit: Non-pregnant people, or pregnant women who are not Black or who cannot provide samples or attend study visits, are unlikely to receive direct benefit from this specific project.
Why it matters
Potential benefit: If successful, this could help identify women at higher risk for preterm birth earlier so they can get closer monitoring or targeted support.
How similar studies have performed: Previous research has linked epigenetic aging measures to stress and health outcomes, but using the rDNA methylation clock specifically to predict preterm birth in Black women is relatively new.
