A nationwide assessment of asthma-mental health nexus among veterans.

OBJECTIVE In this study, we evaluated the association between both current and lifetime asthma to that of mental illness among veterans in the USA. METHODS We utilized the 2005-2013 National Survey on Drug Use and Health data, a national population-based survey in the USA. Mental illness was defined as past year major depressive episode and doctor diagnosis of depression. Survey-weighted univariate and multivariable regression analyses were utilized. A total of 20,581 veterans were included in the study. RESULTS A 4.00% and 7.50% prevalence of current and lifetime asthma were noted among veterans, respectively. A significantly higher prevalence of major depressive episode was noted among veterans with current asthma (8.23%), as compared to those without (4.68%), with a similar trend noted among those with lifetime asthma versus those without (7.84% vs. 4.58%). Doctor diagnosis of depression among veterans was higher among those with current asthma (11.83% vs. 5.86%) and lifetime asthma (10.32% vs. 5.76%), as compared to those without asthma. Upon adjusting for confounders, current asthma was significantly associated with past year major depressive episode [adjusted odds ratio (aOR) = 1.65) and depression diagnosis (aOR = 1.88). Similarly, veterans with lifetime asthma, as compared to those without, had higher odds of past year major depressive episode (aOR = 1.56) and depression diagnosis (aOR = 1.66). CONCLUSION The asthma/mental health nexus is significant among the US veterans. Such results warrant the need for integrated care to address mental health burden among veterans with asthma.
