Co-occurrence of Intimate Partner Violence and Suicide Mortality Among Adolescents and Young Adults in the United States

PurposeSuicide is the second leading cause of death among people ages 10–24 in the United States (US). Intimate partner violence (IPV) is also prevalent, and studies suggest that IPV is associated with youth suicide risk. However, limited research has investigated such associations. We conducted an in-depth analysis of youth suicides that were preceded by or coincided with IPV (i.e., IPV-related) to characterize how decedents were involved in IPV, IPV types experienced, and prior legal systems involvement. MethodsUsing US National Violent Death Reporting System (2014–2018) data for suicide decedents aged 7–24 (n = 15,430 deaths), we manually reviewed case narratives for IPV-related suicides (n = 882) and coded details concerning IPV circumstances. We conducted bivariate analyses to compare IPV-related suicides to other (non-IPV) youth suicides and examined differences in antecedent circumstances between IPV perpetrators (n = 651) and victims (n = 81) using multivariable logistic regression. ResultsAmong IPV-related suicides, most decedents were male and were described as IPV perpetrators. Physical IPV was most frequently reported. Compared to decedents with a history of IPV perpetration, decedents with a history of IPV victimization were more often female and younger. Narratives of IPV victim decedents had higher odds of reporting physical IPV; narratives of IPV perpetrator decedents had higher odds of reporting psychological IPV. DiscussionFuture research should explore the relationship between IPV perpetration and suicide and potential impacts on surviving partners. Research and practice should seek to develop effective assessments and interventions for young people that address IPV and suicide risk simultaneously.

A natural language processing approach to detect inconsistencies in death investigation notes attributing suicide circumstances

BackgroundData accuracy is essential for scientific research and policy development. The National Violent Death Reporting System (NVDRS) data is widely used for discovering the patterns and causing factors of death. Recent studies suggested the annotation inconsistencies within the NVDRS and the potential impact on erroneous suicide-circumstance attributions.MethodsWe present an empirical Natural Language Processing (NLP) approach to detect annotation inconsistencies and adopt a cross-validation-like paradigm to identify possible label errors. We analyzed 267,804 suicide death incidents between 2003 and 2020 from the NVDRS. We measured annotation inconsistency by the degree of changes in the F-1 score.ResultsOur results show that incorporating the target state’s data into training the suicide-circumstance classifier brings an increase of 5.4% to the F-1 score on the target state’s test set and a decrease of 1.1% on other states’ test set.ConclusionsTo conclude, we present an NLP framework to detect the annotation inconsistencies, show the effectiveness of identifying and rectifying possible label errors, and eventually propose an improvement solution to improve the coding consistency of human annotators.

Suicide Mortality During the Perinatal Period

The US has the highest maternal mortality rate among developed countries. The Centers for Disease Control and Prevention deems nearly all of these deaths preventable, especially those attributable to mental health conditions. Coordination between US health care and social service systems could help further characterize circumstances and risks associated with perinatal suicide mortality. To examine contextual and individual precipitating circumstances and risks associated with perinatal suicide. This cross-sectional observational study used a convergent mixed methods design to explore factors contributing to maternal suicides and deaths of undetermined intent (hereinafter, undetermined deaths) identified in National Violent Death Reporting System (NVDRS) data for January 1, 2003, to December 31, 2021. Analyses included decedents who were aged 10 to 50 years and pregnant or post partum at death (collectively, the perinatal group) and demographically matched female decedents who were not pregnant or recently pregnant (nonperinatal group) at death. Analyses were performed between December 2022 and December 2023. Pregnancy status at death (perinatal or nonperinatal). The main outcomes included contributing circumstances associated with suicides and undetermined deaths cited in coroner, medical examiner, or law enforcement case narratives. The study examined quantitative differences between groups using a matched analysis and characterized key themes of salient suicide circumstances using qualitative content analysis. This study included 1150 perinatal decedents identified in the NVDRS: 456 (39.6%) were pregnant at death, 203 (17.7%) were pregnant within 42 days of death, and 491 (42.7%) were pregnant within 43 to 365 days before death, yielding 694 postpartum decedents. The nonperinatal comparison group included 17 655 female decedents aged 10 to 50 years. The mean (SD) age was 29.1 (7.4) years for perinatal decedents and 35.8 (10.8) years for nonperinatal decedents. Compared with matched nonperinatal decedents, perinatal decedents had higher odds of the following identified contributing circumstances: intimate partner problems (IPPs) (odds ratio [OR], 1.45 [95% CI, 1.23-1.72]), recent argument (OR, 1.33 [95% CI, 1.09-1.61]), depressed mood (OR, 1.39 [95% CI, 1.19-1.63]), substance abuse or other abuse (OR, 1.21 [95% CI, 1.03-1.42]), physical health problems (OR, 1.37 [95% CI, 1.09-1.72]), and death of a family member or friend (OR, 1.47 [95% CI, 1.06-2.02]). The findings of the qualitative analysis emphasized the importance of mental health and identified 128 decedents (12.4%) with postpartum depression. This study provides insights into complex factors surrounding maternal suicide, and it highlights opportunities for further research to understand long-term consequences of perinatal mental health. These findings also underscore the need for targeted evidence-based interventions and effective policies targeting mental health, substance use, and IPPs to prevent maternal suicide and enhance maternal health outcomes.

Artificial Intelligence and the National Violent Death Reporting System: A Rapid Review.

As the awareness on violent deaths from guns, drugs, and suicides emerges as a public health crisis in the United States, attempts to prevent injury and mortality through nursing research are critical. The National Violent Death Reporting System provides public health surveillance of US violent deaths; however, understanding the National Violent Death Reporting System's research utility is limited. The purpose of our rapid review of the 2019-2023 literature was to understand to what extent artificial intelligence methods are being used with the National Violent Death Reporting System. We identified 16 National Violent Death Reporting System artificial intelligence studies, with more than half published after 2020. The text-rich content of National Violent Death Reporting System enabled researchers to center their artificial intelligence approaches mostly on natural language processing (50%) or natural language processing and machine learning (37%). Significant heterogeneity in approaches, techniques, and processes was noted across the studies, with critical methods information often lacking. The aims and focus of National Violent Death Reporting System studies were homogeneous and mostly examined suicide among nurses and older adults. Our findings suggested that artificial intelligence is a promising approach to the National Violent Death Reporting System data with significant untapped potential in its use. Artificial intelligence may prove to be a powerful tool enabling nursing scholars and practitioners to reduce the number of preventable, violent deaths.

Examining predictors of suicide by firearm in young, middle, and late adulthood.

Suicide remains a leading cause of death in the U.S., and firearms are one of the most lethal methods of suicide. This study examines personal and contextual factors that predict suicide with a firearm compared to other methods across stages of adulthood. Data on adult suicide decedents from 2009 to 2019 were obtained from Colorado's National Violent Death Reporting System (NVDRS) data (N = 11,512). The dataset includes incident and person characteristics collected by law enforcement and coroners. Zip code level data were integrated from the American Community Survey. Age, sex, race, marital status, military service, substance use, suicide attempt history, mental health, and location characteristics (population density, as well as age, education, veteran status, and household status of population) predicted suicide by firearm. Risk was particularly high for males in older adulthood. We further explored age-specific models (young, middle-aged, and older adults) to determine salient risk factors for each group. This study highlights the need for comprehensive suicide prevention approaches that consider both individual and contextual risk factors, as well as unique risks in each stage of adulthood.

Depression in older women who died by suicide: associations with other suicide contributors and suicide methods

Suicides among older women have received little research attention. In this study based on the 2017–2019 National Violent Death Reporting System data, we examined the prevalence of depression in older female suicide decedents (N = 3,061), associations between depression and other suicide precipitants, and the associations between suicide methods and depression. Descriptive statistics and generalized linear models (GLM) for a Poisson distribution with a log link were used to examine the research questions. Of the decedents, 15.0% had depressed mood without a reported diagnosis and 41.8% had a depression diagnosis. Nearly one-half of the decedents with reported depression were receiving mental health/substance use treatment at the time of injury. The likelihood of depression was lower among those who were age 85 and older compared to those were age 65–74, but higher among those who had anxiety disorder (IRR = 1.50, 95% CI = 1.33–1.69), history of suicidal ideation (IRR = 1.22, 95% CI = 1.10–1.35), history of suicide attempt (IRR = 1.27, 95% CI = 1.14–1.41), and bereavement problems (IRR = 1.45, 95% CI = 1.27–1.65). Those who had depression were less likely to have used firearms (IRR = 0.85, 95% CI = 0.75–0.97) but more likely to have used hanging/suffocation (IRR = 1.37, 95% CI = 1.13–1.67). The findings show that gun ownership was likely an important factor for firearm use. The high prevalence of depressed mood and/or depression diagnosis among older female suicide decedents at the time of their fatal injury underscores the importance of assessing depression and providing evidence-based depression treatment as an essential suicide prevention approach.

Child maltreatment among victims of violent death: an analysis of national violent death reporting system data, 2014–2018

BackgroundLimited information is known about the impact of childhood maltreatment on lifetime risk of violent death. This study aimed to compare manner of death, demographics, age at time of death, and the presence of a mental health or substance use disorder among decedents of violent deaths with a history of child maltreatment to those without.MethodsThis cross-sectional study compared characteristics of pediatric and adult violent deaths with and without a history of child maltreatment that were captured in the National Violent Death Reporting System from 2014 through 2018.ResultsDecedents who were male, multiracial, and had adulthood substance or mental health disorders were more likely to have a history of maltreatment. All-age decedents with a history of maltreatment were more likely to die by homicide. Adult decedents with a history of maltreatment were more likely to die by suicide. Maltreated decedents died significantly younger than non-maltreated decedents.ConclusionsAmong victims of violent deaths, an identified history of child maltreatment was associated with increased risk of homicide across the lifespan, adult suicide, and earlier death. A history of child maltreatment was also associated with mental health and substance use disorders, which may reflect one of the pathways through which the child maltreatment-to-death association functions.

Suicides among American Indian/Alaska Native firefighters: Data from the National Violent Death Reporting System, 2003 – 2017

Suicide is a significant public health problem in the United States and disproportionally affects male American Indian/Alaska Natives (AI/AN). Suicide is particularly problematic among AI/AN firefighters who are more likely to report suicide ideation, planning, attempts, and risk compared to non-Hispanic white (NHW) firefighters. The aim of the current study was to compare non-Hispanic AI/AN firefighter and NHW firefighter suicide decedents by demographics and risk/precipitating factors using National Violent Death Reporting System data for 45 male non-Hispanic AI/AN firefighter and 588 male NHW firefighter decedents who died by suicide. Compared to NHW firefighter decedents, AI/AN firefighter decedents were significantly younger and had significantly higher odds of experiencing alcohol use problems and a recent death/suicide of a family member/friend. AI/AN firefighter decedents had significantly lower odds of documented mental health problems, documented diagnosis of depression/dysthymia, receipt of mental health treatment, or leaving a suicide note compared to NHW firefighter decedents. Results from this study may inform tailored suicide prevention and screening efforts among first responders with the goal of lowering suicide mortality among AI/AN firefighters and fire service as a whole.

Firearm Possession Rates in Home Countries and Firearm Suicide Rates Among US- and Foreign-Born Suicide Decedents in the United States: Analysis of Combined Data from the National Violent Death Reporting System and the Small Arms Survey.

Suicide by firearms is a serious public health issue in the United States. However, little research has been conducted on the relationship between cultural backgrounds and suicide by firearms, specifically in those born and raised in the United States compared to those who have immigrated to the United States. To better understand the relationship between cultural backgrounds and suicide, this study aimed to examine firearm suicide rates among US- and foreign-born suicide decedents based on the firearm possession rate in the decedent's home country. Multivariate logistic regression was performed to analyze data of 28,895 suicide decedents from 37 states obtained from the 2017 National Violent Death Reporting System data set. The firearm possession rate in the home countries of foreign-born suicide decedents was obtained from the 2017 Small Arms Survey. The firearm suicide rate was about twice as high among US-born suicide decedents compared to their foreign-born counterparts. Meanwhile, suicide by hanging was about 75% higher among foreign-born compared to US-born suicide decedents. Those from countries with a low-to-medium firearm possession rate were significantly less likely to use firearms compared to US-born suicide decedents (adjusted odds ratio [AOR]=0.45, 95% CI 0.31-0.65, and AOR=0.46, 95% CI 0.39-0.53, respectively). Meanwhile, firearm suicide rates were not different between US- and foreign-born suicide decedents from countries with a similarly high firearm possession rate. The results suggest that there is an association between using firearms as a means of suicide and the firearm possession rate in the decedent's home country. Suicide by firearms in the United States needs to be understood in the sociocultural context related to firearm possession.

Homicides of psychologists, physicians, nurses, pharmacists, social workers, and other health professionals: National Violent Death Reporting System data 2003-2020.

Homicide is the extreme endpoint along the continuum of interpersonal violence. Violence in healthcare settings and directed toward healthcare workers has been a growing concern. Analysis of health professionals' homicides is needed to inform prevention interventions. Decedent numbers, age, and sex in the National Violent Death Reporting System are reported for 10 types of health professionals: advance practice registered nurses, dentists, nurses, pharmacists, physicians, physician assistants, psychiatrists, psychologists, social workers, and veterinarians. Between 2003 and 2020, 944 homicides of these professionals were reported to the NVDRS. Nearly 80% of victims were women; 53% of homicides involved guns. Nurses, social workers, physicians, and pharmacists comprised the most victims. In 2020, nurses, social workers, pharmacists, and psychologists had the highest homicide rates relative to their workforce size. Few of these homicides were related to professionals' work. The number of homicides within these professions correlated highly with the size of professions' workforces. Health professionals' homicides constitute a small proportion of US homicides generally at lower rates than seen in the general population. Age is likely one of the protective factors. Future, more comprehensive data will provide greater insights into emerging trends to inform strategies to mitigate homicide risk in health professionals. Prevention needs to go beyond healthcare settings and address societal roots of violence.

Safer Behind Bars? Comparing In-Custody Deaths Prior to and During Incarceration

IntroductionThis project aims to characterize trauma-associated deaths of the American incarcerated population through legal intervention (LI) or death by law enforcement officials while in custody before and during incarceration. We determined the preceding events leading to violent death, including initiation of medical care, use of restraints and force, and demographics of the victims. MethodsWe used National Violent Death Reporting System data from the years 2003-2019 to identify deaths that occurred while in custody or incarcerated, including discriminate and narrative data. Event information included weapon type, location of death, incident type, incarceration status, use of restraints, and prone positioning. ResultsThere were 86 victims who died from LI included in the analysis. Most events occurred after incarceration. All victims in our cohort were male, and race was an associated factor for death by LI. Only 16% of victims had an education level above high school/general educational development. Death by firearm compared to other weapons was significantly more common in the in-custody but not yet incarcerated group (83% versus 42%, P ≤ 0.0001). Other associated factors included a history of mental health, physical confrontations, the belief that the victim had a weapon, and being restrained in prone positioning. ConclusionsOur study shows that racial minority victims are disproportionately affected by LI deaths. Firearms and restraint type were important factors in LI deaths. Our findings suggest that violence prevention in the justice system should focus on prevention and de-escalation across setting with specific attention to use of force and inmate access to the weapons of police, guards, and other law and justice system workers. More transparent quality data is sorely needed to adequately define and address this problem.

Surveillance for Violent Deaths — National Violent Death Reporting System, 48 States, the District of Columbia, and Puerto Rico, 2020

An analysis of suicides among first responders ─ Findings from the National Violent Death Reporting System, 2015–2017

Introduction: First responders, including law enforcement officers (LEOs), firefighters, emergency medical services (EMS) clinicians, and public safety telecommunicators, face unique occupational stressors and may be at elevated risk for suicide. This study characterized suicides among first responders and identifies potential opportunities for additional data collection. Methods: Using suicides identified from the three most recent years of National Violent Death Reporting System data with industry and occupation codes from the NIOSH Industry and Occupation Computerized Coding System (2015–2017), decedents were categorized as first responders or non-first responders based on usual occupation. Chi-square tests were used to evaluate differences in sociodemographic and suicide circumstances between first and non-first responders. Results: First responder decedents made up 1% of all suicides. Over half of first responders (58%) were LEOs, 21% were firefighters, 18% were EMS clinicians, and 2% were public safety telecommunicators. Compared to non-first responder decedents, more first responders served in the military (23% vs. 11%) and used a firearm as the method of injury (69% vs. 44%). Among first responder decedents for whom circumstances were known, intimate partner problems, job problems, and physical health problems were most frequent. Some common risk factors for suicide (history of suicidal thoughts, previous suicide attempt, alcohol/substance abuse problem) were significantly lower among first responders. Selected sociodemographics and characteristics were compared across first responder occupations. Compared to firefighters and EMS clinicians, LEO decedents had slightly lower percentages of depressed mood, mental health problems, history of suicidal thoughts, and history of suicide attempts. Conclusions: While this analysis provides a small glimpse into some of these stressors, more detailed research may help inform future suicide prevention efforts and interventions. Practical application: Understanding stressors and their relation to suicide and suicidal behaviors can facilitate suicide prevention among this critical workforce.

Precipitating Circumstances Associated With Intimate Partner Problem–Related Suicides

In 2020, suicide was the 12th leading cause of death among adults in the U.S. Previous research has shown that one common precipitating circumstance among adult suicide decedents is experiencing intimate partner problems (IPPs), such as divorce, separation, romantic break-ups, arguments, conflicts, and intimate partner violence. This study examines how precipitating factors differ between IPP- and non-IPP-related suicides. In 2022, this study analyzed National Violent Death Reporting System data from adult suicide decedents in 48 states and 2 territories between 2003 and 2020. Multivariable logistic regression models were used to compare precipitating circumstances between IPP- and non-IPP-related suicides, controlling for sociodemographic characteristics. Of the 402,391 suicides, 20% (n=80,717) were known to be IPP-related. Circumstances that significantly increased the odds of IPP-related suicides included a history of suicidal thoughts and attempts and mental health problems (depressed mood, alcohol problem, mental health diagnosis), life stressors (interpersonal violence perpetration and victimization, arguments, financial problems, job problems, family problems), and recent legal problems. Non-IPP-related suicides were more likely to occur among older individuals and to be precipitated by a physical health problem or crime. The findings can inform prevention strategies that build resiliency and problem-solving skills, strengthen economic support, and identify and assist people at risk for IPP-related suicides. The Centers for Disease Control and Prevention's Suicide Resource for Action and Intimate Partner Violence Prevention resource packages highlight the best available evidence for policies, programs, and practices related to preventing suicides and IPP.

Circumstances Contributing to Installation, Maintenance, and Repair Worker Death by Suicide.

To examine risk factors related to death by suicide among installation, maintenance, and repair (IMR) workers compared with workers in other occupational groups. The National Violent Death Reporting System (NVDRS) data for the years 2013 to 2018 was used to identify suicide deaths. Circumstance variables were used to examine differences between IMR workers and other workers. Having a physical health problem (1.13; 95% confidence interval [CI], 1.03 to 1.23) or a diagnosis of posttraumatic stress disorder (1.24; 95% CI, 1.03 to 1.50) was more likely to contribute to IMR worker suicide compared with other occupations. Installation, maintenance, and repair workers were less likely to receive treatment for a mental health diagnosis or substance use disorder (0.88; 95% CI, 0.81 to 0.94). Additional support for physical health problems, posttraumatic stress disorder diagnoses, and mental health care access among IMR workers may reduce suicide deaths.
