Assessing risk for severe domestic violence and related homicides perpetrated by partners and in-laws: adapted danger assessments for women in abusive relationships in India.

Despite domestic violence and related homicides perpetrated by partners and/or in-laws being a significant public health problem in India, there are no reliable and valid instruments to identify and intervene with women in domestic violence relationships. Continued domestic violence can escalate to severe, near-lethal, or lethal violence or homicide. The Danger Assessment (DA) is a risk assessment instrument designed to assess the likelihood of severe, near-lethal, or lethal violence in abusive relationships. However, the DA is not designed to determine the risk of future severe, near-lethal, or lethal violence by in-laws. In-law abuse plays a significant role in domestic violence-related homicides in India and other countries with similar cultural norms. This study addressed this gap by developing the Danger Assessment for in-laws (DA-L) to assess risk from in-laws, alongside the Danger Assessment for Women in India (DA-WI) to assess risk from partners. The study also examined the psychometric properties of the DA-L and DA-WI. Longitudinal data from 150 women in India were used to measure the reliability and validity of the two versions of the DA. The original DA items and additional risk items were examined using relative risk ratios for their relationship with severe violence at three-month follow-ups. Predictive validity was tested with the receiver operating characteristic curve. The study resulted in reliable and valid measures (11 items DA-L and 26-items DA-WI) of risk. The versions of the DA can be useful for practitioners in India and those working with Indian women in the US and other countries. The DAs can be used for identifying women in domestic violence relationships who are at risk for future severe domestic violence and guide the provision of tailored safety plans.

Surveillance for Violent Deaths - National Violent Death Reporting System, 48 States, the District of Columbia, and Puerto Rico, 2021.

Problem/Condition: In 2021, approximately 75,000 persons died of violence-related injuries in the United States. This report summarizes data from CDC's National Violent Death Reporting System (NVDRS) on violent deaths that occurred in 48 states, the District of Columbia, and Puerto Rico in 2021. Results are reported by sex, age group, race and ethnicity, method of injury, type of location where the injury occurred, circumstances of injury, and other selected characteristics. This report introduces additional incident and circumstance variables, which now include child victim-specific circumstance information. This report also incorporates new U.S. Census Bureau race and ethnicity categories, which now account for more than one race and Native Hawaiian or other Pacific Islander categories and include updated denominators to calculate rates for these populations. Period Covered: 2021. Description of System: NVDRS collects data regarding violent deaths from death certificates, coroner and medical examiner records, and law enforcement reports. This report includes data collected for violent deaths that occurred in 2021. Data were collected from 48 states (all states with exception of Florida and Hawaii), the District of Columbia, and Puerto Rico. Forty-six states had statewide data, two additional states had data from counties representing a subset of their population (31 California counties, representing 64% of its population, and 13 Texas counties, representing 63% of its population), and the District of Columbia and Puerto Rico had jurisdiction-wide data. NVDRS collates information for each violent death and links deaths that are related (e.g., multiple homicides, homicide followed by suicide, or multiple suicides) into a single incident. Results: For 2021, NVDRS collected information on 68,866 fatal incidents involving 70,688 deaths that occurred in 48 states (46 states collecting statewide data, 31 California counties, and 13 Texas counties), and the District of Columbia. The deaths captured in NVDRS accounted for 86.5% of all homicides, legal intervention deaths, suicides, unintentional firearm injury deaths, and deaths of undetermined intent in the United States in 2021. In addition, information was collected for 816 fatal incidents involving 880 deaths in Puerto Rico. Data for Puerto Rico were analyzed separately. Of the 70,688 deaths, the majority (58.2%) were suicides, followed by homicides (31.5%), deaths of undetermined intent that might be due to violence (8.2%), legal intervention deaths (1.3%) (i.e., deaths caused by law enforcement and other persons with legal authority to use deadly force acting in the line of duty, excluding legal executions), and unintentional firearm injury deaths (<1.0%). The term "legal intervention" is a classification incorporated into the International Classification of Diseases, Tenth Revision, and does not denote the lawfulness or legality of the circumstances surrounding a death caused by law enforcement.Demographic patterns and circumstances varied by manner of death. The suicide rate was higher for males than for females. Across all age groups, the suicide rate was highest among adults aged ≥85 years. In addition, non-Hispanic American Indian or Alaska Native (AI/AN) persons had the highest suicide rates among all racial and ethnic groups. Among both males and females, the most common method of injury for suicide was a firearm. Among all suicide victims, when circumstances were known (84.4%), suicide was most often preceded by a mental health, intimate partner, or physical health problem or by a recent or impending crisis during the previous or upcoming 2 weeks. The homicide rate was higher for males than for females. Among all homicide victims, the homicide rate was highest among persons aged 20-24 years compared with other age groups. Non-Hispanic Black or African American (Black) males experienced the highest homicide rate of any racial or ethnic group. Among all homicide victims, the most common method of injury was a firearm. When the relationship between a homicide victim and a suspect was known, the suspect was most frequently an acquaintance or friend for male victims and a current or former intimate partner for female victims. Homicide most often was precipitated by an argument or conflict, occurred in conjunction with another crime, or, for female victims, was related to intimate partner violence. Nearly all victims of legal intervention deaths were male, and the legal intervention death rate was highest among men aged 30-34 years. The legal intervention death rate was highest among AI/AN males, followed by Black males. A firearm was used in the majority of legal intervention deaths. When circumstances were known, the most frequent circumstances reported for legal intervention deaths were as follows: the victim used a weapon in the incident and the victim had a substance use problem (other than alcohol use). Other causes of death included unintentional firearm injury deaths and deaths of undetermined intent. Unintentional firearm injury deaths were most frequently experienced by males, non-Hispanic White (White) persons, and persons aged 15-24 years. These deaths most frequently occurred while the shooter was playing with a firearm and were precipitated by a person unintentionally pulling the trigger. The rate of deaths of undetermined intent was highest among males, particularly among AI/AN and Black males, and among adults aged 30-54 years. Poisoning was the most common method of injury in deaths of undetermined intent, and opioids were detected in nearly 80% of decedents tested for those substances. Interpretation: This report provides a detailed summary of data from NVDRS on violent deaths that occurred in 2021. The suicide rate was highest among AI/AN and White males, whereas the homicide rate was highest among Black males. Intimate partner violence precipitated a large proportion of homicides for females. Mental health problems, intimate partner problems, interpersonal conflicts, and acute life stressors were primary precipitating circumstances for multiple types of deaths examined. Public Health Action: Violence is preventable, and data can guide public health action. NVDRS data are used to monitor the occurrence of violence-related fatal injuries and assist public health authorities in developing, implementing, and evaluating programs, policies, and practices to reduce and prevent violent deaths. NVDRS data can be used to enhance prevention efforts into actionable strategies. States or jurisdictions have used their Violent Death Reporting System (VDRS) data to guide suicide prevention efforts and highlight where additional focus is needed. For example, North Carolina VDRS program data have played a significant role in expanding activities related to firearm safety and injury prevention. The program served as a primary data source for partners, which led to the creation of the Office of Violence Prevention in the state, focusing on combatting firearm-related deaths. In Maine, the VDRS provided data on law enforcement officer suicides that were used to help support a bill mandating mental health resiliency and awareness training in the state's law enforcement training academy, along with plans for similar training addressing mental health, substance use, and alcohol problems among corrections officers. In addition, states and jurisdictions have also used their VDRS data to examine factors related to homicide in their state or jurisdiction. For example, Georgia VDRS collaborated with the City of Atlanta Mayor's Office of Violence Reduction to develop two public dashboards that not only offer comprehensive data on violent deaths but also present data on the geographic distribution of populations disproportionately affected by violence to help inform violence prevention interventions.

[Homicides in southern South American cities: educational inequalities and economic fluctuations]. / Homicidios en ciudades del sur de Sudamérica: desigualdades educativas y fluctuaciones económicas.

Information on how economic fluctuations affect educational inequalities in homicides in Latin America is scarce. This study aimed to: (a) analyze the temporal variations of educational inequalities related to homicide mortality and (b) compare these inequalities between years of economic growth and recession in southern South America cities from 2000 to 2019. Data from seven urban areas in three countries in the Southern Cone of South America were used: Mendoza and Rosario (Argentina); Belo Horizonte, Curitiba, Rio de Janeiro, and São Paulo (Brazil); and Santiago (Chile). Poisson models were estimated by using age, sex, city of residence, year of economic growth or recession, and schooling level as explanatory variables. Results showed significant differences in the temporal evolution of homicide rates in the seven cities, although populations with a low schooling level always showed the most vulnerability. The four Brazilian cities, analyzed together, showed greater educational inequalities related to homicides in years of economic recession when compared to those of economic growth. On the one hand, the indiscriminate use of force by the State against criminal groups seems to increase social inequality in homicide mortality. On the other hand, criminal fragmentation and economic crisis can exacerbate these inequalities by increasing territorial disputes between criminal groups.

Se sabe poco sobre cómo las fluctuaciones económicas afectan las desigualdades educativas en homicidios en países latinoamericanos. Los objetivos de este estudio fueron (a) analizar las variaciones temporales de las desigualdades relativas educacionales de la mortalidad por homicidio, y (b) comparar estas desigualdades entre años de crecimiento económico y años de recesión en ciudades del sur sudamericano durante el período 2000-2019. Se utilizaron datos de siete áreas urbanas, en tres países del Cono Sur Sudamericano: Mendoza y Rosario (Argentina); Belo Horizonte, Curitiba, Rio de Janeiro y São Paulo (Brasil); y Santiago (Chile). Se estimaron modelos de Poisson, utilizando como variables explicativas la edad, sexo, año, ciudad de residencia, año de expansión o recesión económica y nivel educativo. Encontramos diferencias marcadas en la evolución temporal de las tasas de homicidio entre las siete ciudades, aunque siempre las poblaciones de nivel educativo bajo fueron las más vulnerables. Las cuatro ciudades de Brasil, analizadas en conjunto, tuvieron desigualdades educativas relativas de homicidios mayores en años de recesión económica, con respecto a años de crecimiento económico. Por un lado, el uso de la fuerza indiscriminado por parte del Estado enfocado hacia grupos criminales parece haber llevado a una creciente desigualdad social de la mortalidad por homicidio. Por el otro, en un contexto de fragmentación criminal y crisis económica se podrían agravar estas desigualdades a través de mayores disputas territoriales entre grupos criminales.

São escassas as informações sobre como as flutuações econômicas afetam as desigualdades educacionais em homicídios na América Latina. Os objetivos deste estudo foram: (a) analisar as variações temporais das desigualdades educacionais relacionadas à mortalidade por homicídio, e (b) comparar essas desigualdades entre os anos de crescimento econômico e os anos de recessão nas cidades do sul da América do Sul no período de 2000 a 2019. Foram utilizados dados de sete áreas urbanas, em três países do Cone Sul da América do Sul: Mendoza e Rosário (Argentina); Belo Horizonte, Curitiba, Rio de Janeiro e São Paulo (Brasil); e Santiago (Chile). Os modelos de Poisson foram estimados utilizando como variáveis explicativas a idade, sexo, ano, cidade de residência, ano de expansão ou recessão econômica e nível de escolaridade. Os resultados mostraram diferenças significativas na evolução temporal das taxas de homicídio entre as sete cidades, apesar de que as populações com baixo nível de escolaridade sempre foram as mais vulneráveis. As quatro cidades brasileiras, analisadas em conjunto, apresentaram maiores desigualdades educacionais relacionadas a homicídios em anos de recessão econômica em relação aos anos de crescimento econômico. Por um lado, o uso indiscriminado da força pelo Estado contra grupos criminosos parece ter levado ao aumento da desigualdade social na mortalidade por homicídio. Por outro lado, em um contexto de fragmentação criminal e crise econômica, essas desigualdades podem ser exacerbadas pelo aumento das disputas territoriais entre grupos criminosos.

Child abuse and neglect-related murders in South Africa: a comparison of two national surveys in 2009 and 2017.

BACKGROUND: Population-based statistics on deaths from child abuse and neglect are only routinely available in countries that have reliable national statistics on child murder. For low-income and middle-income countries, relatively little is known about prevalence trends of child murder. South Africa is an exception, having conducted dedicated national studies on child murders for 2009 and 2017 to provide data on child murders overall and on child abuse and neglect-related murders. We aimed to compare child abuse and neglect-related murders in South Africa across two surveys to determine any change between 2009 and 2017. METHODS: We conducted two retrospective national mortuary-based surveys on murder of children aged 0-17 years for 2009 and 2017 from a proportionate random sample of medico-legal laboratories in South Africa. A sampling frame of medico-legal laboratories for each study year was prepared with stratification by medico-legal laboratory size. A minimum of 2 years after the crime was allowed before data collection to enable progression of the investigation process. Child abuse and neglect-related murders were identified using both medico-legal laboratory post-mortem autopsy reports and police data. To identify a child abuse and neglect-related murder, we primarily used the framework of abuse happening within the context of responsibility of care arrangements but broadened this to include all perpetrators and abuse identified from the data. We stratified age into 0-4, 5-9, 10-14, and 15-17 years and further stratified children younger than 5 years into early neonates (newborns killed within 6 days of birth), 7 days to 11 months, and 1-4 years. We calculated incidence rate ratios (IRR) with 95% CIs to compare rates between 2009 and 2017. FINDINGS: An estimated 458 (95% CI 377-539) children in 2009 and 213 (179-247) children in 2017 were murdered in circumstances of child abuse and neglect. The percentage of all child murders that were child abuse and neglect-related declined from 2009 to 2017 (458 [45·0%] of 1018 in 2009 vs 213 [25·0%] of 851 in 2017), with the overall age-standardised rate decreasing from 2·6 to 1·1 per 100 000 children aged 0-17 years (IRR 0·43 [95% CI 0·35-0·54]). Girls represented 276 (60·3%) of 458 murders in 2009, which declined to 96 (45·1%) of 213 murders in 2017, and boys represented 178 (38·9%) of 458 murders in 2009 and 109 (51·4%) of 213 murders in 2017. The decrease was statistically significant for girls in the 0-4 year (IRR 0·33 [0·22-0·49]) and 5-9 year (0·33 [0·15-0·73]) age groups and for boys in the 0-4 year age group (0·49 [0·33-0·71]). Among early neonates (within 6 days of birth), the decrease in child abuse and neglect-related murders was more pronounced among girls than among boys (IRR 0·33 [95% CI 0·19-0·56] vs 0·46 [0·28-0·77]). INTERPRETATION: Child abuse and neglect-related murders are common in South Africa but our study shows that they can be reduced. The high rate of these murders points to the need to continue research and monitoring to inform priority targeted interventions and to better understand the impact of child support policies. FUNDING: Ford Foundation and South African Medical Research Council.

Characterization of Homicides in Mexico: Analysis of 2015-2022.

BACKGROUND: In Mexico, homicides are the leading cause of death among men aged 15 to 44 years; however, despite their increase in recent decades, the study of this issue is insufficient, given its magnitude and impact. Therefore, this study aimed to characterize the spatial and temporal patterns and associated factors of homicides in Mexico from 2015 to 2022. METHODS: An analytical cross-sectional study was conducted, analyzing death records from the National Institute of Statistics and Geography's general mortality databases. Simple frequencies and incidence rates per 100,000 inhabitants by sex, year, and state of the Mexican Republic were calculated. Mortality was evaluated by age groups and geographic areas, and bivariate logistic regression models with sociodemographic variables were performed. RESULTS: Records of 229,182 homicides in Mexico were analyzed, with a median age of 33 years, interquartile range 18. A total of 203,898 (88.96%) were men and 25,284 (11.04%) were women. The majority of deaths occurred in public places and were caused by firearms; women had a higher percentage of homicides at home. States with high incidence rates for both sexes were Chihuahua, Zacatecas, Michoacán, Colima, and Estado de México. The total years of life lost were 9.19 million years. The national incidence of homicides in men showed an upward trend from 2015 to 2019; however, in the case of women, this incidence increased in various age groups during the study period. Occupation, education, marital status, and place of occurrence had significant associations in the logistic regression models. CONCLUSIONS: This study provides a spatial-temporal characterization of homicides in Mexico between 2015 and 2022, highlighting the high incidence in men and the upward trend in certain age groups among women. These findings underscore the need for preventive measures and public policies to address this issue in a multisectoral manner.

Risk for Suicide and Homicide Peaks at Night: Findings From the National Violent Death Reporting System, 35 States, 2003-2017.

Objective: The Mind after Midnight hypothesis proposes that nocturnal wakefulness increases the risk for dysregulated behaviors. Prior studies highlight a greater risk for suicide at night after adjusting for population wakefulness. How this risk varies hour to hour, differs across subgroups, or applies to other behaviors is unknown.Methods: Data on 78,647 suicides and 50,526 homicides from the National Violent Death Reporting System were combined with population wakefulness data for 2003-2017 from the American Time Use Survey. Hourly incident risk ratios (IRRs) were estimated after adjusting for population wakefulness. Two-way analysis of variances identified significant time-by-subgroup interactions that were quantified in post hoc analyses.Results: Suicide counts peaked at 12:00 PM, while homicide counts peaked at 10:00- 11:00 PM. Adjusting for demographics and population wakefulness revealed a 5-fold greater risk for suicide at 3:00 AM (aIRR: 5.20 [4.74-5.70]) and an 8-fold greater risk for homicide at 2:00 AM (aIRR: 8.04 [6.35-10.2]). Hourly risk for suicide varied by age, ethnicity, blood alcohol level, and current partner conflict. Hourly risk for homicide varied by sex and blood alcohol level.Conclusions: Risk for suicide and homicide is greater at night than expected based on the number of people awake at that time. Nighttime risk was greater among young adults and those intoxicated with alcohol, but not among those with a history of suicidal ideation or attempts. Further research should evaluate mechanisms of risk and confirm these findings at an individual level.

Physician homicide: Reports in the National Violent Death Reporting System (2003-2018).

OBJECTIVE: To explore the occurrence, demographics, and circumstances of homicides of physicians. METHOD: Authors interrogated the National Violent Death Reporting System (NVDRS), the Centers for Disease Control and Prevention's surveillance system tracking violent deaths between 2003 and 2018 which integrates data from law enforcement and coroner/medical examiner reports. Authors identified cases of homicide decedents whose profession was physician, surgeon, or psychiatrist. Data collected included decedents' demographics as well as circumstances of death. RESULTS: Data were provided by 7-41 states as participating states increased over time. Fifty-six homicides were reported, most were male (73.2%) and white (76.8%). Most (67.9%) identified assailants reportedly knew decedents: 23.2% were perpetrated by partners/ex-partners; 10.7% by patients/patients' family members. Deaths were mainly due to gunshot wounds (44.6%), stabbing (16.1%), and blunt force trauma (16.1%). More (58.9%) homicides occurred at victims' homes than work (16.1%). CONCLUSIONS: Physician homicides are relatively rare and occur at lower rates than in the general population. Physicians were more frequently killed by partners or ex-partners than by patients. Most homicides occurred away from the workplace. Broader efforts are needed to promote interventions throughout America's violent society to reduce domestic/partner violence and gun violence.

Racial and Ethnic Disparities in All-Cause and Cause-Specific Mortality Among US Youth.

Importance: Mortality rates in US youth have increased in recent years. An understanding of the role of racial and ethnic disparities in these increases is lacking. Objective: To compare all-cause and cause-specific mortality trends and rates among youth with Hispanic ethnicity and non-Hispanic American Indian or Alaska Native, Asian or Pacific Islander, Black, and White race. Design, Setting, and Participants: This cross-sectional study conducted temporal analysis (1999-2020) and comparison of aggregate mortality rates (2016-2020) for youth aged 1 to 19 years using US Centers for Disease Control and Prevention Wide-Ranging Online Data for Epidemiologic Research database. Data were analyzed from June 30, 2023, to January 17, 2024. Main Outcomes and Measures: Pooled, all-cause, and cause-specific mortality rates per 100 000 youth (hereinafter, per 100 000) for leading underlying causes of death were compared. Injuries were classified by mechanism and intent. Results: Between 1999 and 2020, there were 491 680 deaths among US youth, including 8894 (1.8%) American Indian or Alaska Native, 14 507 (3.0%) Asian or Pacific Islander, 110 154 (22.4%) Black, 89 251 (18.2%) Hispanic, and 267 452 (54.4%) White youth. Between 2016 and 2020, pooled all-cause mortality rates were 48.79 per 100 000 (95% CI, 46.58-51.00) in American Indian or Alaska Native youth, 15.25 per 100 000 (95% CI, 14.75-15.76) in Asian or Pacific Islander youth, 42.33 per 100 000 (95% CI, 41.81-42.86) in Black youth, 21.48 per 100 000 (95% CI, 21.19-21.77) in Hispanic youth, and 24.07 per 100 000 (95% CI, 23.86-24.28) in White youth. All-cause mortality ratios compared with White youth were 2.03 (95% CI, 1.93-2.12) among American Indian or Alaska Native youth, 0.63 (95% CI, 0.61-0.66) among Asian or Pacific Islander youth, 1.76 (95% CI, 1.73-1.79) among Black youth, and 0.89 (95% CI, 0.88-0.91) among Hispanic youth. From 2016 to 2020, the homicide rate in Black youth was 12.81 (95% CI, 12.52-13.10) per 100 000, which was 10.20 (95% CI, 9.75-10.66) times that of White youth. The suicide rate for American Indian or Alaska Native youth was 11.37 (95% CI, 10.30-12.43) per 100 000, which was 2.60 (95% CI, 2.35-2.86) times that of White youth. The firearm mortality rate for Black youth was 12.88 (95% CI, 12.59-13.17) per 100 000, which was 4.14 (95% CI, 4.00-4.28) times that of White youth. American Indian or Alaska Native youth had a firearm mortality rate of 6.67 (95% CI, 5.85-7.49) per 100 000, which was 2.14 (95% CI, 1.88- 2.43) times that of White youth. Black youth had an asthma mortality rate of 1.10 (95% CI, 1.01-1.18) per 100 000, which was 7.80 (95% CI, 6.78-8.99) times that of White youth. Conclusions and Relevance: In this study, racial and ethnic disparities were observed for almost all leading causes of injury and disease that were associated with recent increases in youth mortality rates. Addressing the increasing disparities affecting American Indian or Alaska Native and Black youth will require efforts to prevent homicide and suicide, especially those events involving firearms.

States' Abortion Laws Associated With Intimate Partner Violence-Related Homicide Of Women And Girls In The US, 2014-20.

Women who are pregnant or recently gave birth are significantly more likely to be killed by an intimate partner than nonpregnant, nonpostpartum women of reproductive age, implicating the risk of fatal violence conferred by pregnancy itself. The rapidly increasing passage of state legislation has restricted or banned access to abortion care across the US. We used the most recent and only source of population-based data to examine the association between state laws that restrict access to abortion and trends in intimate partner violence-related homicide among women and girls ages 10-44 during the period 2014-20. Using robust difference-in-differences ecologic modeling, we found that enforcement of each additional Targeted Regulation of Abortion Providers (TRAP) law was associated with a 3.4 percent increase in the rate of intimate partner violence-related homicide in this population. We estimated that 24.3 intimate partner violence-related homicides of women and girls ages 10-44 were associated with TRAP laws implemented in the states and years included in this analysis. Assessment of policies that restrict access to abortion should consider their potential harm to reproductive-age women through the risk for violent death.

Evaluating Firearm Violence After New Jersey's Cash Bail Reform.

Importance: Reducing the pretrial detention population has been a cornerstone of movements to end mass incarceration. Across many US cities, there are ongoing public debates on policies that would end pretrial detention due to the inability to afford bail, with some raising concerns that doing so would increase community violence. Objective: To evaluate changes in firearm violence after New Jersey's 2017 bail reform policy that eliminated financial barriers to avoiding pretrial detention. Design, Setting, and Participants: This case-control study used synthetic control methods to examine changes in firearm mortality and combined fatal and nonfatal shootings in New Jersey (2014-2019). New Jersey was chosen because it was one of the first states to systematically implement cash bail reform. Outcomes in New Jersey were compared with a weighted combination of 36 states that did not implement any kind of reform to pretrial detention during the study period. Data were analyzed from April 2023 to March 2024. Exposure: Implementation of New Jersey's cash bail reform law in 2017. Main Outcomes and Measures: Quarterly rates of fatal and nonfatal firearm assault injuries and firearm self-harm injuries per 100 000 people. Results: Although New Jersey's pretrial detention population dramatically decreased under bail reform, the study did not find evidence of increases in overall firearm mortality (average treatment effect on the treated, -0.26 deaths per 100 000) or gun violence (average treatment effect on the treated, -0.24 deaths per 100 000), or within racialized groups during the postpolicy period. Conclusions and Relevance: Incarceration and gun violence are major public health problems impacting racially and economically marginalized groups. Cash bail reform may be an important tool for reducing pretrial detention and advancing health equity without exacerbating community violence.

Firearm Homicide Demographics Before and After the COVID-19 Pandemic.

This cross-sectional study evaluates changes in firearm homicide demographics before and after the COVID-19 pandemic.

Police killings of unarmed Black persons and suicides among Black youth in the US: A national time-series analysis.

INTRODUCTION: Suicide deaths among Black youth in the US have increased rapidly over the past decade. Direct or vicarious racial trauma experienced through exposure to police brutality may underlie these concerning trends. METHODS: We obtained nationally aggregated monthly counts of suicides for non-Hispanic Black and White youth (age ≤ 24 years) and adults (age > 24 years) from the National Mortality Vital Statistics restricted-use data files provided by the Centers for Disease Control and Prevention, from 2013 to 2019. Monthly counts of Black youth suicides constituted our main outcome. We defined our exposure as the monthly counts of police killings of unarmed Black persons over 84 months (2013 to 2019), retrieved from the Mapping Police Violence database. We used ARIMA (AutoRegressive Integrated Moving Average) time-series analyses to examine whether Black youth suicides increased within 0 to 3 months following police killings of unarmed Black persons, controlling for autocorrelation and corresponding series of White youth suicides. RESULTS: Suicides among Black youth increase by ∼1 count three months following an increase in police killings of unarmed Black persons (exposure lag 0 coefficient = 0.16, p > 0.05; exposure lag 1 coefficient = -0.70, p > 0.05; exposure lag 2 coefficient = -0.54, p > 0.05; exposure lag 3 coefficient = 0.95, p < 0.05). The observed increase in suicides concentrates among Black male youth (exposure lag 3 coefficient = 0.88, p < 0.05).

"There's room to do more": a mixed-methods study of the Temporary Assistance for Needy Families (TANF) diversion program and intimate partner violence in Georgia.

Introduction: Intimate partner violence (IPV) is a risk factor for homicides and suicides. As poverty is both a predictor and a consequence of IPV, interventions that alleviate poverty-related stressors could mitigate IPV-related harms. Temporary Assistance for Needy Families (TANF), a monthly cash assistance program, is one such potential intervention. In the state of Georgia, the TANF diversion program, which provides a non-recurrent lump-sum payment to deter individuals from monthly TANF benefits, is an understudied component of TANF that may influence the effectiveness of state TANF programs in supporting IPV survivors. Aim: This study quantifies and qualifies the role of Georgia's TANF diversion program in shaping IPV-related mortality. Methods: This study relies on a mixed-methods sequential explanatory design. Using data from the Georgia Violent Death Reporting System (GA-VDRS), an interrupted time series analysis was conducted to estimate the effect of TANF diversion on IPV-related homicides and suicides. Semi-structured interviews were then administered with TANF policy experts and advocates, welfare caseworkers, and benefit recipients (n = 20) to contextualize the quantitative findings. Results: The interrupted time series analysis revealed three fewer IPV-related deaths per month after implementing TANF diversion, compared to pre-diversion forecasts (coefficient = -3.003, 95%CI [-5.474, -0.532]). However, the qualitative interviews illustrated three themes regarding TANF diversion: (1) it is a "band-aid" solution to the access barriers associated with TANF, (2) it provides short-term relief to recipients making hard choices, and (3) its limitations reveal avenues for policy change. Discussion: While diversion has the potential to reduce deaths from IPV, it may be an insufficient means of mitigating the poverty-related contributors to IPV harms. Its limitations unveil the need for improved programs to better support IPV survivors.

To investigate the pattern of neck injuries and the role of toxicology in cases of hanging and manual/homicidal ligature strangulation in Ireland between 2016 - 2020: A retrospective review and analysis.

The pattern of neck injuries sustained in fatal cases of external compression to the neck is recorded during Post Mortem Examinations (PME), to assist in the interpretation of the circumstances that led to death. In this study, the PMEs performed for 298 cases of hanging and strangulation occurring between 2016 and 2020 in Ireland were retrospectively reviewed for the purpose of recording and collating the external and internal neck injuries observed during each PME, as well as the toxicology results for each decedent. Statistical analysis was performed to investigate potential novel associations between anthropometric variables pertaining to the decedents and the PME findings in cases of hanging and strangulation, serving to add further data to the existing body of research in this area and to assist in the resolution of future cases of hanging or strangulation where there are conflicting findings. In completing statistical analysis, it was found that there was no discernible association between the occurrences of cartilaginous neck fractures (CNFs) with increasing ligature width. Positive associations between increasing weight and BMI of the decedents were identified, and a significantly positive association between the increasing height of the decedent and the incidence of CNFs were identified. Analysis of the toxicology demonstrated that antipsychotics were implicated most frequently in cases of incomplete and complete hanging associated with CNFs and that opioids were implicated most frequently in cases of manual and ligature strangulation associated with CNFs. OBJECTIVE: To record the pattern of neck injuries sustained in retrospective cases of hanging and manual/ligature strangulation and to collate these findings so as to provide scientific evidence to support the interpretation of the findings in future cases of suicidal hanging and homicidal manual/ligature strangulation for the purpose of medicolegal investigation. To analyse the associations between the occurrence of neck fractures and anthropometric variables pertaining to the victims in cases of complete hanging. STUDY DESIGN: The reports of 298 Post Mortem Examinations (PMEs) performed for cases of hanging and manual/homicidal ligature strangulation between 2016 and 2020 in Ireland were retrospectively reviewed. Pseudoanonymised data sets were recorded for each report, which included the following parameters: neck injuries (soft tissue and cartilaginous), weight, height, BMI and ligature width, toxicology, noose position, ligature material, tongue protrusion, sex and age. Permission for the use of this data was sought from the pathologists and coroners involved in these cases. The data was analysed according to descriptive statistical methods and logistic regression analysis. RESULTS: Logistic regression analysis was undertaken to examine the associations between unit increases in ligature width and increases in a set of physical characteristics of the decedents (weight, BMI and height) with the occurrence of CNFs. Increasing ligature width was not found to increase the likelihood of a CNF occurring, where the Odds Ratio (OR) for this event occurring was 0.9596. Unit increases in body weight and BMI were found to increase the likelihood of the occurrence of a CNF with ORs of 1.0166 and 1.0607 respectively. Increasing height of the decedent yielded an OR = 4.64, demonstrating that CNFs are significantly more likely to occur with increasing height (CI 95 %: 0.2915, 73.9559). CONCLUSIONS: According to the statistical analysis performed for this study, increasing weight, height and BMI are parameters of the decedents which increase the likelihood of the occurrence of CNFs in cases of complete hanging.

A special type of homicide-suicide: A retrospective study of the characteristics of extended suicide.

Extended suicide, a specific type of homicide-suicide event, has severe social consequences yet remains lacking systematic research. This retrospective study investigated 51 cases of extended suicide involving mental disorders in central China with aim of better understanding risk factors for such events and guiding prevention strategies. Over an 8-year period from 2015 to 2022, cases were collected from forensic institutions, and demographic characteristics, case details, and psychiatric data were recorded. The 51 incidents involved 51 perpetrators and 79 victims, with more female perpetrators (58.8%) and more female victims (54.4%). The average age of the perpetrators was 36.1, and most were married (88.2%). Almost all of the victims were family members of the perpetrator, like the most numerous children (64.6%), followed by spouses (24.1%). The most common homicide mode of death was mechanical asphyxia (38.0%), followed by sharp devices (36.7%) and drug poisoning (16.5%). Depressive disorders (76.5%) were the most common diagnosis of mental disorder for perpetrators. The study analyzed the unique characteristics of extended suicide to enrich such data. These findings help strengthen the screening and identification of potential perpetrators and victims to prevent such cases from occurring.

Community exposure to gun homicide and adolescents' educational aspirations.

INTRODUCTION: Witnessing violence and violent victimization have detrimental effects on adolescents' emotional functioning and ability to envision and plan for their futures. However, research is limited on the impact of violence that occurs in adolescents' communities-whether or not it was witnessed or experienced firsthand. This paper investigated the associations between community exposure to gun homicide and adolescents' high school and college graduation aspirations. METHODS: We analyzed data from the Future of Families and Child Wellbeing Study (N = 3031), a cohort study of children born 1998-2000 in 20 large US cities, merged with incident-level data on deadly gun violence from the Gun Violence Archive (2014-2017). Outcomes were reported by adolescents (girls and boys) during wave 6 (2014-2017) of the study, conducted when the children were 15 years of age. We employed ordinary least squares regression, ordered logistic regression, and multilevel stratification to examine the average and heterogeneous impacts of community exposure to gun homicide on adolescents' educational aspirations. RESULTS: Community exposure to gun homicide was associated with reduced high school graduation aspirations, particularly among adolescents with the lowest risk of exposure to gun homicide. Gun homicide exposure was also associated with increased college graduation aspirations; this association was concentrated among adolescents with moderate-high risk of exposure. CONCLUSIONS: Given the importance of education for job opportunities and the better health that accompanies education and occupational attainment, preventing early exposure to gun violence and providing institutional supports to help adolescents facing adversity realize their goals is essential to their long-term health and success.

Reporting and Description of Research Methodology in Studies Estimating Effects of Firearm Policies.

BACKGROUND: Evidence about which firearm policies work, to what extent, and for whom is hotly debated, perhaps partly because variation in research methodology has produced mixed and inconclusive effect estimates. We conducted a scoping review of firearm policy research in the health sciences in the United States, focusing on methodological considerations for causal inference. METHODS: We identified original, empirical articles indexed in PubMed from 1 January 2000 to 1 September 2021 that examined any of 18 prespecified firearm policies. We extracted key study components, including policy type(s) examined, policy operationalization, outcomes, study setting and population, study approach and design, causal language, and whether and how authors acknowledged potential sources of bias. RESULTS: We screened 7733 articles and included 124. A plurality of studies used a legislative score as their primary exposure (n = 39; 32%) and did not examine change in policies over time (n = 47; 38%). Most examined firearm homicide (n = 51; 41%) or firearm suicide (n = 40; 32%) as outcomes. One-third adjusted for other firearm policies (n = 41; 33%). Three studies (2%) explicitly mentioned that their goal was to estimate causal effects, but over half used language implying causality (n = 72; 58%). Most acknowledged causal identification assumptions of temporality (n = 91; 73%) and exchangeability (n = 111; 90%); other assumptions were less often acknowledged. One-third of studies included bias analyses (n = 42; 34%). CONCLUSIONS: We identified a range of methodologic approaches in firearm policy research in the health sciences. Acknowledging the imitations of data availability and quality, we identify opportunities to improve causal inferences about and reporting on the effects of firearm policies on population health.

Relationships of State Alcohol Policy Environments With Homicides and Suicides.

INTRODUCTION: Alcohol use is involved in a large proportion of homicides and suicides each year in the U.S., but there is limited evidence on how policies targeting alcohol influence violence in the U.S. CONTEXT: Extant studies generally focus on individual policies in isolation of each other. This study examines the impacts of changes in states' alcohol policy restrictions on overall homicide and suicide rates and firearm-related homicide and suicide rates using a holistic measure of states' alcohol policy environments. METHODS: Using a composite measure of state-level alcohol policies (Alcohol Policy Scale) and data from the National Vital Statistics System from 2002 to 2018, this study applied a Bayesian time series model to estimate the impacts of alcohol policy changes on overall and firearm-involved homicide and suicide rates. The analysis was performed in 2023 and 2024. RESULTS: A 1 SD change in the Alcohol Policy Scale was associated with a 6% decline in homicide rates both overall (incident rate ratio=0.94; 95% credible interval = 0.89, 1.00) and for firearm homicides specifically (incident rate ratio=0.94, 95% CI=0.88, 1.01). There was no clear association of alcohol policy with suicides. The model predicts that a nationwide increase in alcohol restrictions equivalent to a shift from the 25th to 75th percentile of the scale's distribution would result in almost 1,200 fewer homicides annually. CONCLUSIONS: Increases in the restrictiveness of state-level alcohol policies are associated with reductions in homicides. More restrictive alcohol policy environments may offer an opportunity to reduce homicides.
