More than 2 million children in the U.S. have had parents deployed to Iraq or Afghanistan during the wars there and about 40% of them are under five. Researchers from the Boston University School of Medicine studied 169 families with children aged between one-and-a-half and five who were enrolled in the military childcare centres at a large Marine base in 2007. Children aged 3 and older who had a deployed parent had significantly higher scores on measures of externalizing and overall behaviour than children of the same age without a deployed parent. The reported symptoms remained the same after controlling for parental stress and depression and were the same whether parents or childcare providers were reporting them.
