a new research published in Biological journal of psychiatry points out that the different negative situations have opposite effects the biological development of the child.
The main authority, Dr. Katie McLaughlin of the University of Washington, points out that while childhood violence at an early age (physical, emotional or sexual abuse) is related to acceleration of biological aging, children exposed to difficulties of life because poverty and food insecurity show a delay in their biological development.
Accelerating the biological aging associated with childhood violence is linked to epigenetic aging (DNA genes). This by increasing the symptoms of depression. In conclusion, this violence "gets under the skin", according to the author, and later develops complications for human health.
This finding was completed after an experiment in 247 children aged between 8 and 16 years. These findings indicate that accelerated aging after exposure to violence at an early age can already be detected in children up to 8 years of age, McLaughlin said.
With this new research, it is obvious that a greater investment of society is needed reducing the exposure of children to violence. There must also be more biomedical and psychological research to reduce their impact negative experiences in the lives of vulnerable children, "adds biological psychiatric editor John Krystal.
The survey opens the door to new questions about whether this effect of acceleration of aging is permanent or can be eliminated.
Genetic aging related to depression identified in research will also help mental health professionals identify, more easily, in children and adolescents who need more medical support, McLaughlin is over.
