Research Article: Suicidal Behaviors Among Active-Duty US Service Members: Data from the Health-Related Behaviors Survey
Abstract:
Suicide was the second-leading cause of death among the – year old age group and the tenth-leading cause of death for all age groups in the US population between and . Similarly, from to , suicide, or self-inflicted death, represented .% of deaths among US military active-duty servicemembers (SMs) and was second only to accidental (unintentional) as a cause of death. Between and , suicide rates among SMs doubled; since there have been no appreciable changes in the annual rate of approximately . deaths per , service members. The rate of suicide in the civilian population was . per , in , decreasing to . in and increasing to . in . While the unadjusted rate among enlisted US military service members (SMs) is significantly higher than the US civilian population estimate, the age- and sex-adjusted military rate may be similar to the US adult population. Service in the military is voluntary and the demographic distribution among the US military is not representative of the US general population, and rates vary by model. Suicides and suicidal behaviors are preventable. Suicidal behaviors such as suicidal ideation (SI), suicide plans (SP), and suicide attempts (SA) represent key indicators for prevention efforts to reduce suicide-related deaths. Survey studies provide valuable self-reported information on the burden of suicidal behaviors among a population. It is common that survey studies use a single-item assessment of SI, SP, and SA to measure the presence or absence of each behavior during three timeframes (eg, lifetime, past year, and past month). For example, the lifetime prevalence estimates of SA, SP, and SI among military personnel are .%, .%, and .%, respectively. A recent representative survey of Army members during their basic combat training reported similar estimates of SI (.%) and SA (.%). In contrast, a one-year study in the Air Force reported a lower prevalence of suicidal ideation of % among males and .% among females, and .% of the ideators reported SA. Suicidal behaviors during deployment have been of particular concern, although the estimates of medically documented SA among deployed SMs was low (.%). This indicates that estimates from medically documented records or administrative data might be lower than those obtained from surveys. We proposed this study to estimate the prevalence of suicidal behaviors using a survey because it represents an appropriate source for this estimation. In addition, most of the studies that assessed risk factors of suicidal behaviors among SMs were based on medically documented records or administrative data.– In this vulnerable population, suicidal behaviors have been associated with demographic variables including young age, female gender,– white race,– marital status, high-school education or less,, the first four years in service, and enlisted ranks. These studies have shown inconsistent findings as suicide remains to be a serious problem among non-White males in middle age and later life. This conflicting evidence warrants further investigation using an intersectional approach, as the contribution of race might depend on gender or age groups. To our knowledge, there has been no research assessing such associations in active-duty SMs. We aimed to address this gap to improve risk stratification of suicidal behaviors in clinical settings, particularly in the general medical practice and specialty clinics. Finally, studies among active-duty SMs have documented the association between suicidal behaviors and mental health conditions, including anxiety, depression, posttraumatic stress disorder, and having received a mental health diagnosis. These factors represent traditional risk factors for suicidal behaviors in the military and non-military populations., In this study, we ) explored data-driven mental health conditions and substance use profiles in SMs, and ) evaluated hypothesized relationships by assessing how different risk profiles correlate with suicidal behaviors. The Department of Defense (DoD) Survey of Health-Related Behaviors (HRBS) has been an important source of health behavior information for the military by surveying both active-duty and reserve components periodically since ., Research on suicidal behaviors is lacking in HRBS respondents. This study utilizes data from the HRBS of active-duty service members to ) estimate the prevalence of Suicidal behaviors (SI and SA) among active-duty SMs; ) determine whether differences exist by age, sex, and race; and ) assess whether prevalence estimates vary by risk profiles of mental health conditions and substance use. We hypothesized that the latent class analysis would identify distinct groups of illegal drug users and mental health needs and that these groups would increase the odds of suicidal behaviors. We also hypothesized that sex and age might modify race differences in reporting suicidal behaviors.
