In group two to four, 43 per cent of the children experienced isolated incidents of adversity in childhood, mainly related to poverty or illness in the family. Here the researchers found a mortality rate in early adulthood that is 1.3-1.8 times higher than in group one.
The study revealed that three per cent in group five experienced great social and stressful adversity throughout childhood. In this group, the mortality rate is 4.5 times higher than in group one.
