Associations between psychological and respiratory distress in post-deployment Veterans

ABSTRACT

Since September 11, 2001, over 2.7 million United States service members have deployed to South-West Asia and the Middle East and have been exposed to environmental hazards and psychological trauma. Many of these service members have returned with medical and psychological illnesses, some of which have proved complex and resistant to treatment. One notable constellation of symptoms is post-deployment respiratory illness, which has become a focus of research and policy efforts. The present study sought to examine the impact of post-deployment psychological distress on respiratory symptom severity. Data were obtained from the Veterans Affairs Airborne Hazards and Open Burn Pit Registry (AHOBPR) health surveillance database (N =107,403). Psychological factors were compared against common organic and environmental predictors of post-deployment respiratory distress. Psychological distress following deployment was a stronger predictor of 12-month shortness of breath severity than general respiratory pathology or level of exposure to environmental hazards, controlling for gender, age, race, and tobacco use. Additionally, psychological distress was a better predictor of shortness of breath severity than documented respiratory illnesses including asthma, chronic obstructive pulmonary disease, and chronic bronchitis. Implications and directions for future research are discussed, as well as potential alterations to existing treatment and health surveillance paradigms.
