Incidences of anxiety disorders among active duty service members between 1999 and 2018.

PURPOSE: Anxiety disorders can impact the health, performance, and retention of military service members. To inform prevention initiatives and long-term treatment planning, incidence rates across anxiety disorders were evaluated among U.S. active-duty service members over a 20-year period.

METHOD: Data were extracted from the Defense Medical Epidemiological Database to examine incidence rates of generalized anxiety disorder (GAD), panic disorder (PD), agoraphobia (AG), social anxiety disorder (SAD), obsessive compulsive disorder (OCD), agoraphobia with panic disorder (AWPD), agoraphobia without history of panic disorder (AWOPD), and unspecified anxiety disorder (UAD) among 151,844 service members between 1999 and 2018 in relation to sex, age, race, marital status, military pay grade, service branch.

RESULTS

Incidence rates of anxiety disorders increased significantly over the 20-year period. Anxiety disorder incidence rates ranged widely from 0.01 to 23.70 (per 1000 service members). There were significant differences in observed versus expected diagnostic rates across all demographic variables examined (p < 0.001).

CONCLUSION

Incidence rates varied considerably across the anxiety disorders, with UAD being the highest. These data highlight the importance of health care professionals attending to anxiety disorders, in order to plan for service member needs, develop preventative interventions, address early detection, and deliver treatments to improve combat readiness.
