Children Growing-up with Domestic Violence Age Prematurely?

I think we can all agree that domestic violence has a negative impact on children, but does it also cause premature ageing?

According to recent studies carried out by North Carolina's Duke University, scientists suggest that it does. Their conclusions are based on the scientific measurements of Telomeres (the ends of chromosomes) on children exposed to violence which keep DNA sequences intact like shoelace caps prevent shoelaces from unravelling. They've found that violence, aggression and abuse in the lives of children causes changes in their DNA that can lead to seven to ten years of premature aging. Given this recent finding, along with the devastating effects already known which can range from ill health, depression, nightmares, bed wetting, temper tantrums, etc. Should children be removed from abusive environments, even if the parent chose to stay, or do we focus on supporting the survivor/parent? What do you think?
