Byrne SP, McCarthy E, DeViva JC, et al. - The present study was conducted to explore the prevalence, risk correlates, and health comorbidities of insomnia in US military veterans. Researchers conducted a survey including a nationally representative sample of 4,069 US military veterans to evaluate insomnia severity; military, trauma, medical, and psychiatric histories; and health and psychosocial functioning. The relationship between insomnia severity, psychiatric and medical comorbidities, suicidality, and functioning was examined by performing multivariable analyses. The results showed that nearly 2 in 5 US veterans experience clinical or subthreshold insomnia, which is correlated with substantial health burden and independent risk for suicidal ideation. The data demonstrate the importance of evaluation, monitoring, and treatment of insomnia in veterans as they transition from the military.
