WWII trauma impacts physical and mental health in the oldest old: results from a German population-based study

Epidemiological studies in different traumatised samples indicate an increased risk for numerous physical and mental diseases. It is suspected that this is due to chronic changes in fundamental processes in the immune, nervous, and endocrine systems, which take years to manifest pathologically. Previous studies have considered intervals of a few decades. However, little is known about whether a link between trauma and physical and mental health can be established over very long periods of time and in the oldest old population.

A total of 1,299 German citizens aged 80 and above were interviewed about on-going suffering from the effects of traumatic World War II (WWII) events as well as about physical and mental health. Multiple linear and logistic regression models were used to assess the impact of suffering from the effects of traumatic events on general health, several medical conditions, multimorbidity, pain, and depression.

43.94% of the oldest old were still suffering from the effects of traumatic events in connection with WWII. Participants who were still suffering from the effects of traumatic events were more likely to be treated for heart failure, blood diseases, bladder problems, back pain, respiratory or lung diseases, and sleep disorders. They also had poorer general health, higher multimorbidity, more pain, and higher depression scores.

Findings suggest that chronic psychological suffering from the effects of traumatic events in early life is associated with impaired physical and mental health even seven decades after the events.
