    A study examining the children of people evacuated(撤离) during the WWII showed the daughters of female evacuees were up to four times more likely to suffer from serious mental health conditions compared to those whose parents stayed at home.

In the largest enquiry ever of its kind, researchers examined the health records of 3000 children of Finnish people evacuated to Sweden during the 1941-1945 conflict with Soviet Russia. The evacuees, many of whom were at a pre-school age, were placed with foster families in Sweden and were forced to learn Swedish, later returning to Finland. The study found that the female children of these girls had an increased risk of being hospitalized for conditions such as depression. However, this was not the case with children of boys evacuated during the war.

The study could not determine why. One possibility is that the stress of the evacuees’ experience affected their psychological development in ways that influenced their parenting style. Another possibility is that the evacuees’ experience resulted in epigenetic changes—changed in the way genes are expressed. For example, the researchers mentioned an earlier finding that Holocaust survivors have higher levels of methyl groups bound to the FKBP5 gene and have passed his change on to their children. This higher level of methyl groups appears to change the production of cortisol, a hormone(荷尔蒙) that controls the stress response.

“The Finnish evacuation was intended to protect children from the harm associated with the country’s wars with the Soviet Union”, said study co-author Dr Torsten Santavirta, from Uppsala University.

“Our observation of the long-term psychiatric(精神病的) risk that reached into the next generation is concerning and stresses the need to weigh benefits as well as potential risks when designing policies for child protection”.
