There may be a link between the stressful childhood traumas that certain parents experience and the behavioral health issues their own children develop.
The kind of childhood traumas the children face includes domestic violence at home, separation of parents or divorce, death of a parent, getting estranged from a parent, any physical, emotional or sexual abuse or mental illness of a parent.
Dr Adam Schickedanz, a paediatrician from the David Geffen School of Medicine at the UCLA, said that the parents who suffer from severe trauma or stress in their childhood days were at a double risk of producing children with adverse mental and behavioural illnesses.
The earlier studies looked at the childhood behavioural issues as a risk for later physical as well as mental health issues in their adulthood but this is the first ever study to reveal that the long-term childhood behavioural issues extend across the generations from parent to the children, said Schickedanz in a release.
In the study, thousand so children as well as their parents, who were all a part of the Child Development Supplement (CDS) and Childhood Retrospective Circumstances Study (CRCS) of the year 2014 and were analysed.
The findings of the study showed that the parents which suffered with four or above adverse childhood experiences (ACD) were at a double risk of producing children with attention deficit hyperactivity disorder (ACHD) and these parents were four time more likely to get mental health issues.
As per the scientists, an ACE is described as any type of neglect, abuse or household trauma that might have happened before the age of 18.
Now, the next step for the researchers to do is to look into how some resilience factors, like support of teachers or mentors may help prevent the harm of adverse childhood experiences, said Schickedanze.
The study is published in Pediatrics journal.
