New York Oct 31 (IANS) Young children who face adverse problems such as death of a parent growing up in poverty physical or sexual abuse or having a parent with a psychiatric illness are likely to be at a higher risk of developing health problems in adulthood warn researchers.
Research showed that facing three or more adverse experiences at a time can lead to smaller brain volumes. As a result children are unable to express their emotions properly which leads to depression and worse social and emotional outcomes.
Those who faced adversities between the age group of nine to 15 years were 15 per cent more likely to develop severe depression by their pre-teenage years and early teenage years and 25 per cent more likely to suffer physical health problems like asthma and gastrointestinal disorders.
"Our findings demonstrate how powerful the psychosocial environment can be " said Joan L. Luby Professor at the University of Washington in Missouri US.
"A child s brain doesn t develop based solely on its genetic infrastructure. It is influenced by the stresses of poverty violence the loss of a parent and other adverse experiences which together can have serious health consequences evident as early as the teenage and preteenage years " she added.
The study published in the journal JAMA Pediatrics conducted multiple MRI brain scans on children between three to six years of age which showed that the inferior frontal gyrus -- part of the brain important for language comprehension and production -- was smaller in children with more adverse experiences.
"People exposed to adversity early in life experience changes in the volume of the inferior frontal gyrus that probably can make children more vulnerable to behavioural issues and bad decision-making " Luby said.
