[BDSP. Notice produite par INIST-CNRS YR0xz7VO. Diffusion soumise à autorisation]. The authors estimated the prevalence of post-traumatic stress disorder (PTSD) and illness resembling chronic fatigue syndrome (CFS) in the entire population of Gulf War and non-Gulf-War veterans. They also evaluated the relation between the extent of deployment-related stress and the risk of either PTSD or CFS. In 1995-1997, the authors conducted a health survey in which these two symptom-based medical diagnoses in a population-based sample of 15,000 Gulf War veterans representing four military branches and three unit components (active, reserve, and National Guard) were compared with those of 15,000 non-Gulf veteran controls. Gulf War veterans, compared with non-Gulf veteran controls, reported significantly higher rates of PTSD (adjusted odds ratio=3.1,95% confidence interval : 2.7,3.4) and CFS (adjusted odds ratio=4.8,95% confidence interval : 3.9,5.9). The prevalence of PTSD increased monotonically across six levels of deployment-related stress intensity (test for trend : p
