Can a class tame pregnancy stress at the genetic level?

This trial tests whether a structured educational program, the Maternal Epigenetics Training Module, can reduce stress in pregnant women. The program teaches stress management and explains how stress might affect the mother and fetus through epigenetic mechanisms. Researchers will measure stress levels, cortisol (a stress hormone), and awareness of epigenetic effects in 140 pregnant women who attend prenatal classes. The goal is to see if this education can lower stress and its biological markers during pregnancy.
