Health impacts of war: case studies of New Zealand veterans of the First World War.

Aim: Armed conflict remains a tragic feature of the modern world and so it is necessary to continue to study its health impacts. Even the study of historical conflicts is relevant given that certain health impacts are common to most wars e.g., post-traumatic stress disorder (PTSD).

Methods: This study built on a previous quantitative analysis of a randomly selected group of 200 New Zealand veterans from the First World War (WWI). From this sample we selected 10 cases that illustrated particular themes around morbidity impacts.

Results: The theme of severity of impacts was illustrated with a case who was severely wounded and died from suicide when back in New Zealand, and another case with severe PTSD. The theme of the high frequency of non-fatal conditions was revealed with cases illustrating new diagnoses (a case with n=8 diagnoses), hospitalisations for new conditions (n=6), non-fatal injury events (n=3) and for sexually transmitted infections (n=3). The theme of chronic debility as a consequence of various conditions was illustrated with cases who had suffered from being gassed or having gastroenteritis, malaria or pandemic influenza.

Conclusion: These 10 selected cases reiterate how severe and extensive the morbidity burden for military personnel in WWI could be. Also illustrated is how the morbidity could contribute to adverse impacts on some of their lives after returning to New Zealand.
