Prevalence rates for<unk>  vary according to the diagnostic criteria used. The condition is reported across industrialized countries and it affects women more than men. In 2018, the same researchers reported that the prevalence rate of diagnosed<unk>  had increased by more than 300% and self-reported<unk>  sensitivity by more than 200% in the previous decade. They found that 12.8% of those surveyed reported medically diagnosed<unk>  and 25.9% reported having<unk>  sensitivities. A 2014 study by the Canadian Ministry of Health estimated, based on its survey, that 0.9% of Canadian males and 3.3% of Canadian females had a diagnosis of<unk>  by a health professional. While a 2018 study at the University of Melbourne found that 6.5% of Australian adults reported having a medical diagnosis of<unk>  and that 18.9 per cent reported having adverse reactions to<unk><unk> s. The study also found that for 55.4 per cent of those with<unk> , the symptoms triggered by<unk>  exposures could be disabling. Gulf War syndrome Symptoms attributed to Gulf War syndrome are similar to those reported for<unk> , including headache, fatigue, muscle stiffness, joint pain, inability to concentrate, sleep problems, and gastrointestinal issues. A population-based, cross-sectional epidemiological study involving American veterans of the Gulf War, non-Gulf War veterans, and non-deployed reservists enlisted both during Gulf War era and outside the Gulf War era concluded the prevalence of<unk> -type symptoms in Gulf War veterans was somewhat higher than in non-Gulf War veterans. After adjusting for potentially confounding factors (age, sex, and military training), there was a robust association between individuals with<unk> -type symptoms and psychiatric treatment (either therapy or medication) before deployment and, therefore, before any possible deployment-connected<unk>  exposures. The odds of reporting<unk>  or chronic<unk> -symptom illness was 3.5 times greater for Gulf War veterans than non-Gulf veterans. Gulf War veterans have an increased rate of being diagnosed with<unk> -symptom conditions compared to military personnel deployed to other conflicts.
