New Study Links Children Exposure to Violence with Disease

A new study from Duke University shows that when children are exposed to violence their DNA experiences wear and tear, much like aging.

This elevates their risk of mental and physical disorders as adults.

The findings were published in the journal Molecular Psychiatry.
Violence caused the genetic structures called telomeres to shorten boys and girls between the ages of 5 – 10. After 50 – 60 cell divisions, the telomeres became so small the cells simply shut down.

The researchers showed that this phenomenon was linked to susceptibility to disease because of the telomeres erosion process.

A previous study from the British Environmental-Risk Study referenced children in 1,116 same-sex twins born between 1994 and 1995. Duke researchers focused their work on identical twins in London; many of whom had teenage mothers.

As these children aged, their telomere length shortened. The decline was more severe in children that had been direct victims of violence.

“Kids who are raised in poverty and hardship have more disease. This might explain why,” said Dr. Owen Wolkowitz, a psychiatrist at UC San Francisco who has studied the link between depression and telomere length in adults.

He was not involved in the Duke study.

Researchers for Duke say they have not evaluated the correlation between the children studied and any health issues they may have developed over their lives. However, they are currently assessing the risks of diabetes and hypertension disorders.

Study leader Idan Shalev is sure they will find a connection.
