Soldiers and other personnel returning from Iraq and Afghamistan may be at increased risk of asthma, US study results suggest.
Data gathered from the Vietnam Era Twin Registry on 3,065 twins showed that those in the top quartile for PTSD were 2.3 times more likely to have asthma than those in the lowest PTSD quartile.
Authors commented this was the first evidence of a link between PTSD symptoms and asthma because no previous investigation has included PTSD and asthma in the same community sample.
They added that a number of confounding factors such as educational attainment and confounding factors were controlled in the study.
Combat exposure, which was also measured in the study, was not linked to increased asthma risk.
