Figure 2. Standardized Risk of Suicide Attempt by Mental Health Diagnosis and Deployment Status Among Regular Army Enlisted Soldiers.

Figure 2

The sample of enlisted soldiers (n = 9650 soldiers who attempted suicide and 153 528 control person-months) is a subset of the total sample (n = 193 617 person-months) from the Army Study to Assess Risk and Resilience in Service members Historical Administrative Data Study. Any mental health diagnosis includes most International Classification of Diseases, Ninth Revision, Clinical Modification codes for mental disorders (eg, major depression, bipolar disorder, anxiety disorder, and personality disorders), but excludes postconcussion syndrome and tobacco use disorder when those were the only recorded mental health diagnoses. See eTable 3 in the Supplement for a complete list of included and excluded International Classification of Diseases, Ninth Revision, Clinical Modification codes. Standardized risk estimates (soldiers who attempted suicide per 100 000 person-years) assume other predictors were at their samplewide means. Estimates were calculated based on logistic regression models that included basic sociodemographic and service-related variables (sex, age at entry into the Army, current age, race/ethnicity, education, marital status, and time in service) and also included a dummy predictor variable for calendar month and year to control for secular trends.
