The study was the first to identify earlier patterns of adrenal puberty as a result of prenatal stress.
Adrenal puberty is marked by changes like the growth of body hair, pimples and aspects of cognitive maturation, but does not include breast development or the onset of menstruation for girls or testicular enlargement for boys.
The finding adds to research in the field of fetal programming, studies that explore the impact that stress and other factors affecting pregnant mothers can have on fetuses and children long after birth.
