Suicide
State of Knowledge and Need
“Suicide is among the leading causes of death
and disease burden around the world.
Although there have been significant
advances in suicide research as well as
increases in the treatment of suicidal people,
the rate of suicidal behaviors has not
changed as a result”

The Past…
• “One type of symptomatic behavior associated with
depressions, either neurotic or psychotic in type, is
suicide. Between July, 1940, and June 1946, there
were 2,214 suicides in the Army, 300 of which
occurred among officers.1 ….these figures represent
a sharp drop during the war period from the
peacetime suicide rate in the Army. 2 There was also
a sharp drop in the number of suicides in the Army in
World War “

Administration & Funding
•
•
•
•
Army STARRS is being conducted by a consortium of investigators from the
Uniformed Services University of the Health Sciences (USUHS), the University of
California-San Diego (UCSD), Harvard Medical School (HMS) & the University of
Michigan (UM) in collaboration with the NIMH.
 Co-PIs: R. Ursano (USUHS) & M. Stein (UCSD)
 Site-PIs: R. Kessler (HMS) & S. Heeringa (UM)
 Collaborating NIMH Scientists: L. Colpe & M. Schoenbaum
 Consulting Army Scientists: K. Cox & S. Cersovsky
Supported by NIH Cooperative Agreement U01MH87981.
Funding provided by the Department of the Army ($50M) with supplemental funds
($15M) from the National Institute of Mental Health (NIMH).
Army STARRS in-theater research was conducted under a protocol reviewed and
approved by the U.S. Army Medical Research and Materiel Command (MRMC)
Institutional Review Board, and in accordance with the approved protocol.
Slide 13
Background and Goals
Background: The persistent rise in Army suicide rate led the
Army to ask NIMH to find academic scientists with the expertise
to design & conduct an independent research program that was
large, creative, and comprehensive enough to address this
complicated problem.
Goals: To identify risk and protective factors that impact Soldiers’
well-being so the Army can use them in risk reduction efforts.
• Identify salient risk and protective factors in Army Soldiers
• Inform development & testing of empirically-derived interventions for
Army Soldiers
• Deliver “actionable” findings to the Army rapidly
• Establish Army cohorts for future follow-up studies & continued benefit to
the Army
Slide 14
Study Design
• Army STARRS is not a single study
• Integrated multi-study design
• Involves seven epidemiologic & neurobiologic
studies to comprehensively investigate risk
factors & protective factors for:
– Suicide
– Suicide-related behavior
– Related mental and behavioral health

Approach to Producing
Actionable Findings
Concentration of Risk
•
Who (e.g., MOS, rank, demographics, mental disorders)
•
When (e.g., time in service, deployment status, time pre/post deployment)
•
Where (e.g., installations, training, combat zones, transitioning)
Risk variables
•
Identify risk sub-groups (who, when, where) so Army can consider programs to
target for intervention
Neurocognitive
•
Use neurocognitive tests to identify those at risk and possible neurocognitive
functioning associations with suicidal behavior
Biomarkers
•
Identify biomarkers for those at risk and determine possible neurobiologic
mechanisms

Risk of Suicide Attempt by Month Since
Entering Army, Enlisted Soldiers & Officers
(HADS, 2004-2009, n=193,617)
The sample of 193,617 person-months includes all Regular Army soldiers (i.e., excluding those in the U.S. Army National Guard and
Army Reserve) with a suicide attempt in the administrative records during the years 2004-2009, plus a 1:200 stratified probability
sample of all other active duty Regular Army person-months in the population exclusive of soldiers with a suicide attempt or other nonfatal suicidal event (e.g., suicidal ideation) and person- months associated with death (i.e., suicides, combat deaths, homicides, and
deaths due to other injuries or illnesses). All records in the 1:200 sample were assigned a weight of 200 to adjust for the undersampling of months not associated with suicide attempt.
Slide 27
Examples of Recent Findings
from Historical Administrative Data Study
2004-2009
Historical Administrative Data Study (>975K regular Army Soldiers in 2004-2009)
• Suicide risk increased for those deployed, never deployed, and previously
deployed; deployed & previously deployed at greater risk.
• Suicide risk lower for females than males (as with civilians), but difference
narrowed substantially during deployment.
• Suicide risk was increased for those demoted in past 2 years.
• Currently & previously deployed in first 4 years of service had greater risk
than never deployed.
• Not associated with increased risk of suicide:

Disorders among Nondeployed Soldiers in the
U.S. Army: Results from the Army Study to
Assess Risk and Resilience in
Servicemembers (Army STARRS)
•
•
•

•
•
•
A total of 25.1% of respondents met criteria for any 30-day disorder (15.0%
internalizing; 18.4% externalizing) and 11.1% for multiple disorders.
A total of 76.6% of cases reported pre-enlistment age at onset of at least one 30-day
disorder (49.6% internalizing; 81.7% externalizing).
12.8% of respondents reported severe role impairment.
Controlling for sociodemographic and Army career correlates (which were broadly
consistent with other studies) 30-day disorders with pre-enlistment and postenlistment ages at onset both significantly predicted severe role impairment
Pre-enlistment disorders were more consistent powerful predictors than postenlistment disorders.
Population-attributable risk proportions of severe role impairment were 21.7% for preenlistment disorders, 24.3% for post-enlistment disorders, and 43.4% for all disorders.
Interventions to limit accession or increase resilience of new soldiers with preenlistment mental disorders might reduce prevalence and impairments of mental
disorders in the U.S. Army.
