Although science has long proven that there are many genetic health issues related to genetics, a new study has found that childhood trauma can lead to changes in DNA that can then be passed on to your children. to future generations.
Researchers from the National Institutes of Health have joined forces with the University of Helsinki in Finland and the University of Uppsala in Sweden to conduct this study.
Our future generations could be affected by the traumas experienced during childhood:
Researchers looked at two distinct groups of children, one whose parents had been evacuated from Finland during the Second World War as children and one whose parents had remained at home in Finland during the war. There was a clear difference between those who stayed at home and those who were evacuated, as well as a difference in their children.
While it was thought that those who had stayed and faced the dangers of war would have suffered more trauma, a recent study showed that those who had evacuated had more psychological stress because they were separated from their families and had to learn a new language and adapt to a different culture.
It was found that girls born to women who had been evacuated were more than four times more likely to be hospitalized for mental health problems than girls born to women who had been able to stay at home. Whether or not the mothers of these children were hospitalized as a result of trauma did not affect the outcome.
What was also interesting was that there was no marked difference in the mental health of the sons of women who had been evacuated during the war.
Researchers are not yet sure of the relevance of this difference between sons and daughters.
Previous studies on the effect of trauma in pregnancy have confirmed that this may have an impact on children, but it has never been indicated that a trauma experienced by a mother during childhood could affect her children.
It remains to be confirmed whether this trauma can be passed on to the granddaughters and beyond the trauma victims.
The first possible reason given by the researchers for this phenomenon is related to the parental style. It is possible that the way these women educated their children is very different because of the trauma experienced.
They may have made different choices about how to educate their children because they did not want their children to experience the same trauma they
The other reason is a new branch of science known as epigenetics.
She looks at our genetic markers and studies how things like culture, environment and even lifestyle can affect development and our DNA. In the field of epigenetics, there is epigenetic inheritance, which studies how the effects of trauma can be transmitted from generation to generation.
Evidence that supports epigenetics lies in the differences in health conditions between black Americans and others.
One study concluded that problems such as low birth weight, chronic stress and high infant mortality rates could be linked to years of racial discrimination that affected this group of people at a genetic level.
On the one hand, decision makers need to be particularly aware of the potentially significant harm that can occur when a child experiences a traumatic experience. In addition, people with mental health problems may consider looking more closely at their family tree to find the real root of the problem.
