“We examined how maternal mental health symptoms and perceived stress prior to conception relate to diurnal cortisol slopes and CARs in preschool-aged children. We assessed mothers’ posttraumatic stress disorder (PTSD) symptoms, depressive symptoms, and perceptions of stress after one birth and prior to a subsequent pregnancy. Children provided cortisol samples via saliva at two time points, when they were approximately 4 and 5 years of age.

Translation: The researchers examined whether maternal mental health and stress before pregnancy were related to cortisol patterns in preschool-aged children. They measured mothers’ PTSD, depression, and stress levels before and after pregnancy and collected saliva from children at ages 4 and 5 to measure their cortisol samples

“The goal of the present study was to examine whether maternal mental health and perceived stress reported prior to conception relate to patterns of diurnal cortisol, a non-invasive measure of HPA axis functioning, in preschool-aged children.”

Translation: The goal of the study was to determine whether a mother’s mental health and stress levels before pregnancy are associated with patterns of cortisol, a measure of stress regulation, in children ages younger than 5.

“More PTSD symptoms were associated with flatter cortisol slope at the age of 4 years.”

Translation: The study found that higher levels of PTSD symptoms in mothers before pregnancy were linked to less than normal cortisol patterns in their children at age 4.

“A prospective study of mothers and their children, we found that maternal mental health symptoms prior to pregnancy were associated with diurnal cortisol slopes in early childhood. Symptoms of PTSD in mothers assessed before conception were associated with flatter diurnal cortisol slopes at the ages of 4 (n = 56) and 5(n = 51) years”

Translation: It was found that the mothers mental health before pregnancy influenced the child’s stress systems, higher maternal PTSD symptoms were linked to less than normal cortisol patterns in early childhood

Future research could explore how maternal stress before pregnancy affects children later in life and whether these cortisol changes lead to mental health disorders. It could also examine other factors, such as parenting or environment, that may influence these outcomes

I found it difficult to fully understand how cortisol measurements like diurnal slope and CAR were calculated and what they specifically indicate about stress regulation.
