Homicides of American Indians/Alaska Natives in urban versus rural areas: United States National Violent Death Reporting System, 2003-2020.

BACKGROUND: Missing and Murdered Indigenous People is a historic and contemporary issue that has gained national attention. In 2021, homicide was the eighth leading cause of death among American Indian/Alaska Native (AIAN) persons aged between 1 and 54 years old, and homicide is the sixth leading cause of death among all AIAN males aged 1-54 years old. AIM: These data will build knowledge around AIAN homicides and to identify circumstances that can aid in comprehensive Missing and Murdered Indigenous People prevention efforts. METHODS: AIAN homicide data came from Centers for Disease Control and Prevention's National Violent Death Reporting System, a state/jurisdiction-based surveillance system that collects detailed information about characteristics and circumstances of violent deaths. We examined data from 2003 to 2020 (all available years) from participating states/jurisdictions. We also assessed sociodemographic characteristics of victims and suspects, incident characteristics and differences across dichotomised urban/rural status. The study was conducted in 2022. RESULTS: The National Violent Death Reporting System provided data on 2959 AIAN homicides from 2003 to 2020 (54.2% urban and 45.8% rural). Significant differences based on the two locations included type of weapon used, the location of the injury, race of the primary suspect, the victim's relationship to the suspect and select circumstances precipitating the homicide including crimes precipitating the homicide and homicides stemming from intimate partner violence. OUTCOMES: These findings provide crucial information to strengthen public health efforts for prevention.

Diffusion effects of a sexual violence prevention program leveraging youth-adult partnerships.

The purpose of the current study was to examine the diffusion effects of a youth-led sexual violence prevention program (i.e., Youth Voices in Prevention [Youth VIP]). Specifically, social network analysis was used to measure the extent to which Youth VIP changed behaviors for 1172 middle and high school youth who did not attend program events but were friends with Youth VIP participants and completed the first and final survey (approximately 2 years apart). Findings suggest that there was considerable interpersonal communication about Youth VIP among the students generated by program participation. Specifically, youth with friends who participated in Youth VIP were more likely to report hearing their friends talk about Youth VIP and reported talking to their friends about Youth VIP compared with those not connected to Youth VIP participants. However, there were no diffusion effects found for behavioral outcomes (i.e., bystander intervention behavior, violence victimization, and perpetration). Given the mixed findings, further research is needed to determine the extent to which youth-led sexual violence prevention initiatives lead to changes in broader community-wide changes in youths' behaviors.

Examining Sources of Social Norms Supporting Child Corporal Punishment Among Low-Income Black, Latino, and White Parents.

Child corporal punishment is a prevalent public health problem in the US. Although corporal punishment is sustained through parents' perceptions of social norms supporting this discipline behavior, little research has investigated where these normative perceptions come from. To fill this gap, we conducted 13 focus groups including 75 low-income Black, Latino, and White parents across five states in the US. Results revealed that one influential source of Black and White parents' perceived norms was their positive framing of corporal punishment experiences during childhood. Furthermore, Black parents formed normative perceptions based on identification with parents in their racial/ethnic group, while White parents did so with parents sharing the same generation. Results are interpreted in light of the false consensus effect and self-categorization theory. In contrast, Latino parents viewed their childhood experience of corporal punishment as negative and distanced their parenting practices from those practiced in their countries of origin, suggesting an influence of acculturation. Their perceived norms were likely transmitted through interpersonal communication within their social networks. These findings shed light on how social norms are formed and in turn guide parents' use of corporal punishment as a tool to discipline children.

Evaluating the Impact of a Youth-Led Sexual Violence Prevention Program: Youth Leadership Retreat Outcomes.

Involving youth in developing and implementing prevention programs to reduce sexual violence (SV) has the potential to improve prevention outcomes. However, there has been little focus on youth-led SV prevention programs, and limited evaluation research to help guide efforts. The current study examined the effectiveness of Youth Voices in Prevention (Youth VIP) leadership retreats on SV victimization and perpetration, forms of violence related to SV (e.g., bullying), SV bystander behaviors and readiness, and perceptions of norms related to SV prevention. Results identified mixed findings for program impact, with variations in outcomes that can help guide future youth-led prevention program initiatives. Youth attending a large "kick-off" leadership retreat (that was less youth-led that subsequent smaller retreats) later reported more bystander behaviors, but also reported increased perpetration and victimization, compared to non-attending youth. However, youth attending smaller, more focused leadership retreats held during the school year, reported reductions in sexual harassment perpetration and improved bystander behaviors and attitudes compared to non-attending youth. Evaluation of moderator variables suggests that program impact was generally stronger for younger participants, sexual minority youth, and non-White youth (which were largely Native American youth in this sample). Findings suggest promise for youth-led prevention work but also highlight the need for testing the impact of different training structures and modalities. Clinical trials number: NCT03207386.

Nonvoluntary or Forced Sex Among Women, by Sexual Identity, Attraction, and Behavior - National Survey of Family Growth, United States, 2011-2017.

Nonheterosexual (sexual minority) women report experiencing more sexual violence than heterosexual (sexual majority) women (1,2). Sexual minority women are often categorized as a collective whole, which fails to capture the nuances in sexual violence among subgroups of sexual minority women, such as bisexual and lesbian women (3). To estimate the prevalence of lifetime forced vaginal intercourse (forced sex) and of nonvoluntary first vaginal intercourse among women aged 18-44 years in the United States, CDC analyzed data from female respondents who were interviewed during 2011-2017 for the National Survey of Family Growth (NSFG); respondents were stratified by self-reported sexual identity, attraction, and behavior. Log-binomial regressions and analyses of variance (ANOVAs) were performed to compare experiences across each dimension of sexual orientation, controlling for demographic characteristics. Compared with sexual majority women,* prevalence of any male-perpetrated nonvoluntary first vaginal intercourse or forced sex (nonvoluntary or forced sex) was higher among women who identified as bisexual (36.1% versus 17.5%), reported attraction to the opposite and same sex (30.3% versus 15.8%), and reported sexual behavior with the opposite and same sex (35.7% versus 15.9%). These sexual minority women reported that their earliest experience of nonvoluntary or forced sex occurred at younger ages than did that of sexual majority women. Among women who were unsure of their sexual attraction, the prevalence of nonvoluntary first vaginal intercourse was also higher than among sexual majority women. These findings underscore the need for comprehensive prevention approaches tailored for sexual minority women and prevention of child sexual abuse, given the average ages at earliest nonvoluntary or forced sex experience among sexual minority women (range = 12.5-16.3 years). Additional research is needed into the circumstances of and norms or attitudes that influence perpetration of nonvoluntary or forced sex and broader sexual violence against sexual minority women. Prevention of nonvoluntary or forced sex victimization among sexual minority women will require comprehensive approaches to prevent sexual violence and child sexual abuse. Engaging sexual minority women in the development of sexual violence prevention efforts and research would help ensure that the experiences of sexual minority women across the spectrum are represented.

Exploring injury intentionality and mechanism via ICD-10-CM injury codes and self-reported injury in a large, urban emergency department.

Health systems capture injuries using International Statistical Classification of Diseases and Related Health Problems, 10th Revision, Clinical Modification (ICD-10-CM) diagnostic codes and share data with public health to inform injury surveillance. This study analyses provider-assigned ICD-10-CM injury codes among self-reported injuries to determine the effectiveness of ICD-10-CM coding in capturing injury and assault. METHODS: Self-reported injury screen records from an urban, level 1 trauma centre collected between 20 November 2015 and 30 September 2019 were compared with corresponding provider-assigned ICD-10-CM codes discerning the frequency in which intentions are indicated among patients reporting (1) any injury and (2) assault. RESULTS: Of 380 922 patients screened, 32 788 (8.61%) reported any injury and 6763 (1.78%) reported assault. ICD-10-CM codes had a sensitivity of 67.40% (95% CI 66.89% to 67.91%) for any injury and specificity of 89.79% (95% CI 89.69% to 89.89%]). For assault, ICD-10-CM codes had sensitivity of 2.25% (95% CI 1.91% to 2.63%) and specificity of 99.97% (95% CI 99.97% 99.98%). DISCUSSION: This study found provider-assigned ICD-10-CM had limited sensitivity to identify injury and low sensitivity for assault. This study more fully characterises ICD-10-CM coding system effectiveness in identifying assaults.

Identifying knowledge, self-efficacy and response efficacy of alternative discipline strategies among low-income Black, Latino and White parents.

Corporal punishment (CP) leads to detrimental mental and physical consequences for a child. One way to prevent CP is to encourage parents to apply alternative discipline strategies that do not involve violence. Based on the knowledge-behavior gap framework in public health education, this study analyzed the focus group data of 75 low-income Black, Latino and White parents to uncover commonalties and differences in their knowledge, self-efficacy and response efficacy of alternative discipline strategies. Findings revealed that parents knew several alternative discipline strategies and had confidence in their ability to conduct these strategies. However, parents reported that some strategies were hard to implement because they lacked the relevant resources. Moreover, parents did not perceive that alternative discipline strategies were effective without using some forms of CP. Knowledge, self-efficacy and response efficacy of alternative discipline strategies are risk factors for child physical abuse and addressing them will help prevent injury and health impacts on children, while providing safe, stable, nurturing relationships and environments for child development.

Sexual Violence in the Media: An Exploration of Traditional Print Media Reporting in the United States, 2014-2017.

Sexual violence is prevalent and, for many victims, begins early in life (1). In the United States, one in five women and one in 38 men report completed or attempted rape victimization during their lifetime, with 43.2% of female and 51.3% of male victims reporting that their first rape victimization occurred before age 18 years (1). Media have been shown to act as a socializing agent for a range of health and social behaviors (2). Media portrayals might influence, reinforce, or modify how the public responds to incidents of sexual violence and their support for prevention efforts and media might construct a lens through which the public can understand who is affected by sexual violence, what forms it takes, why it happens, and who is responsible for addressing it (3). Media portrayals of sexual violence were assessed using a systematic random sample of newspaper articles from 48 of the top 50 distributed traditional print media outlets that were examined for sexual violence content and potential differences by geographic region and year of publication. Differences by year and region in type of sexual violence covered, media language used, and outcomes reported were identified, highlighting an opportunity for public health officials, practitioners, and journalists to frame sexual violence as a preventable public health issue and to incorporate best practices from CDC and the National Sexual Violence Resource Center's Sexual Violence Media Guide (4).

Building capacity for injury prevention: a process evaluation of a replication of the Cardiff Violence Prevention Programme in the Southeastern USA.

OBJECTIVES: Violence is a major public health problem in the USA. In 2016, more than 1.6 million assault-related injuries were treated in US emergency departments (EDs). Unfortunately, information about the magnitude and patterns of violent incidents is often incomplete and underreported to law enforcement (LE). In an effort to identify more complete information on violence for the development of prevention programme, a cross-sectoral Cardiff Violence Prevention Programme (Cardiff Model) partnership was established at a large, urban ED with a level I trauma designation and local metropolitan LE agency in the Atlanta, Georgia metropolitan area. The Cardiff Model is a promising violence prevention approach that promotes combining injury data from hospitals and LE. The objective was to describe the Cardiff Model implementation and collaboration between hospital and LE partners. METHODS: The Cardiff Model was replicated in the USA. A process evaluation was conducted by reviewing project materials, nurse surveys and interviews and ED-LE records. RESULTS: Cardiff Model replication centred around four activities: (1) collaboration between the hospital and LE to form a community safety partnership locally called the US Injury Prevention Partnership; (2) building hospital capacity for data collection; (3) data aggregation and analysis and (4) developing and implementing violence prevention interventions based on the data. CONCLUSIONS: The Cardiff Model can be implemented in the USA for sustainable violent injury data surveillance and sharing. Key components include building a strong ED-LE partnership, communicating with each other and hospital staff, engaging in capacity building and sustainability planning.

Traditional and cyber bullying and sexual harassment: A longitudinal assessment of risk and protective factors.

Adolescents engage in bullying and sexual harassment perpetration both in-person and online. Yet, little is known about the overlap of traditional (in-person) and cyber bullying and sexual harassment perpetration. The present study assessed the co-occurrence of these forms of aggression in high school and identified middle school predictors based on participants' perceptions of factors across the social ecology. Racially diverse middle and high school students (n = 3549) were surveyed over four time points from Spring 2008 to Spring 2013. A latent class analysis was used to identify classes of individuals according to endorsement of traditional and cyber bullying and sexual harassment items in high school. Four classes were identified: (1) high all, consisting of traditional and cyber bullying and sexual harassment perpetration (n = 227); (2) traditional bullying perpetration (n = 604); (3) traditional and cyber bullying perpetration (n = 450); and (4) low all (n = 1,261). Students who reported high levels of anger, self-esteem, empathy, pornographic exposure, and traditional masculinity (individual level), lower levels of social support and parental monitoring (relational level), and higher levels of school belonging (community level) had increased odds of being in the high all class when compared to the other classes. Given the co-occurrence of traditional and cyber bullying and sexual harassment, prevention programming that addresses both forms of aggression across traditional and online contexts may be beneficial. This study also suggests the importance of comprehensive prevention efforts that incorporate approaches at the different ecological levels, such as teaching adolescents healthy emotional and interpersonal skills, and engaging parents in prevention.

Violence Victimization, Substance Use, and Suicide Risk Among Sexual Minority High School Students - United States, 2015-2017.

Youths identifying as lesbian, gay, bisexual, or another nonheterosexual identity (sexual minority youths) report more violence victimization, substance use, and suicide risk than do heterosexual youths (1). These disparities are generally attributed to minority stress (the process through which stigma directed toward sexual minorities influences health outcomes) (2,3). Sexual minority youths might experience negative outcomes associated with minority stress differently across sexual identities, but to date, no nationally representative study has examined differences in victimization, substance use, and suicide risk within sexual minority youth. Using pooled data from the 2015 and 2017 national Youth Risk Behavior Surveys (YRBS), relationships between sexual identity groups and victimization, substance use, and suicide risk were evaluated with sex-stratified logistic regression models. Compared with heterosexual students, bisexual females and all sexual minority males reported more victimization; lesbian and bisexual females reported more use of alcohol, cigarettes, and marijuana; and all sexual minority youths reported elevated high-risk substance use and suicide risk. Programmatic efforts to reduce and prevent victimization, substance use, and suicide risk among sexual minority youths might benefit from consideration of issues within group differences.

Health system and law enforcement synergies for injury surveillance, control and prevention: a scoping review.

BACKGROUND: Healthcare providers and law enforcement (LE) officers are among the most common first responders to injuring events. Despite frequent interface between the health system (HS) and LE sectors, the published evidence that supports their collaboration in injury surveillance, control and prevention has not been comprehensively reviewed. METHODS: We conducted a scoping review of literature published from 1990 to 2016 that focused on local and regional HS and LE collaborations in injury surveillance, control and prevention. Our aim was to describe what is known and what remains unexplored about these cross-sector efforts. RESULTS: 128 articles were included in the final review. These were categorised by their focus on either surveillance activities or partnerships in injury control and prevention programmes. The majority of surveillance articles focused on road traffic injuries. Conversely, articles describing partnerships and programme evaluations primarily targeted the prevention of interpersonal violence. DISCUSSION: This review yielded two major findings: overall, the combination of HS and LE injury data added value to surveillance systems, especially as HS data augmented LE data; and HS and LE partnerships have been developed to improve injury control and prevention. However, there are few studies that have evaluated the impact and sustainability of these partnerships. CONCLUSIONS: The current evidence to support HS and LE collaboration in injury surveillance and control and prevention programmes is heterogeneous. Notable gaps suggest ample opportunity for further research and programme evaluation across all types of injury.

Communication competence, psychological well-being, and the mediating role of coping efforts among women with breast cancer: cross-sectional and longitudinal evidence.

Despite existing research identifying psychological benefits of patients' interpersonal competence in various contexts, little longitudinal research has addressed underlying mechanism(s). To address this limitation, we examined both the cross-sectional and longitudinal associations between cancer patients' communication competence in close relationships and psychological well-being, as well as the mediating role of coping efforts. Data came from a larger project with women with breast cancer (N = 661), recruited from April 2005 to May 2007 at three large university-affiliated cancer centers in the U.S. to study the effects of an Internet-based system providing patients and families with a range of services. The present study focused on survey data at baseline, 6 weeks, and 12 weeks after the intervention (controlling for the possible effects of the intervention). Results from both cross-sectional and longitudinal analyses indicated that competence in open communication between patients and their close support persons had a positive association with patients' psychological well-being and that approach coping efforts partially mediated this association. We discussed the implications and limitations of the study.

Parents' Understanding About Children's Bullying: Fall ConsumerStyles Survey, United States, 2017, 2018, and 2019.

The purpose of this study was to explore U.S. parents' and caregivers' understanding about children's bullying-what bullying is and how to address it. We analyzed 2017, 2018, and 2019 Fall ConsumerStyles online panel survey data from U.S. parents/caregivers of children ages 10 to 17 years (N = 1,516), including 20 items representing statements consistent or inconsistent with the bullying prevention evidence and best practices. Percentage of endorsement for each item and a summary measure of understanding about bullying were calculated. The association between low overall understanding about bullying and sociodemographic characteristics was explored. Most parents identified bullying as harmful (77%), repetitive (63%), and involving power imbalance (51%). At least half of parents answered 13 or more items (20 total) consistent with the bullying prevention evidence or best practices. Being male, non-Hispanic Black or Hispanic, having high school or less education, and small household size were associated with higher odds of low overall understanding about bullying. Awareness of parents' understanding about bullying and how to appropriately address it is vital for bullying prevention. Findings can inform the strategic development of bullying prevention health messages for parents.

COVID-19 Vaccine Hesitancy Among US Adults: Safety and Effectiveness Perceptions and Messaging to Increase Vaccine Confidence and Intent to Vaccinate.

OBJECTIVE: Public health agencies have a critical role in providing effective messaging about mitigation strategies during a public health emergency. The objectives of this study were (1) to understand perceptions of COVID-19 vaccines, including concerns about side effects, safety, and effectiveness and how these perceptions influence vaccine decision-making among US adults and (2) to learn what messages might motivate vaccine uptake. METHODS: In April and May 2021, we conducted 14 online focus groups with non-Hispanic English-speaking and English- and Spanish-speaking Hispanic adults (N = 99) not vaccinated against COVID-19. We oversampled adults aged 18-39 years and rural residents and systematically assessed 10 test messages. Researchers used a standardized guide and an a priori codebook for focus group discussions, coding transcripts, and thematic analysis. RESULTS: Vaccine hesitancy factors included fear of the unknown; long-term side effects, including infertility; and beliefs that the vaccines were developed too quickly and were not sufficiently effective. Motivating factors for receiving vaccination included the ability to safely socialize and travel. Health care providers were considered important trusted messengers. Participants were critical of most messages tested. Messages that came across as "honest" about what is not yet known about COVID-19 vaccines were perceived more positively than other messages tested. Messages were seen as ineffective if perceived as vague or lacking in data and specificity. CONCLUSIONS: Messages that were simple and transparent about what is unknown about vaccines relative to emerging science were viewed most favorably. Health care providers, friends, and family were considered influential in vaccination decision-making. Findings underscore the benefits of research-informed strategies for developing and disseminating effective messages addressing critical issues in a public health emergency.

Neural-Net Artificial Pancreas: A Randomized Crossover Trial of a First-in-Class Automated Insulin Delivery Algorithm.

Background: Automated insulin delivery (AID) is now integral to the clinical practice of type 1 diabetes (T1D). The objective of this pilot-feasibility study was to introduce a new regulatory and clinical paradigm-a Neural-Net Artificial Pancreas (NAP)-an encoding of an AID algorithm into a neural network that approximates its action and assess NAP versus the original AID algorithm. Methods: The University of Virginia Model-Predictive Control (UMPC) algorithm was encoded into a neural network, creating its NAP approximation. Seventeen AID users with T1D were recruited and 15 participated in two consecutive 20-h hotel sessions, receiving in random order either NAP or UMPC. Their demographic characteristics were ages 22-68 years old, duration of diabetes 7-58 years, gender 10/5 female/male, White Non-Hispanic/Black 13/2, and baseline glycated hemoglobin 5.4%-8.1%. Results: The time-in-range (TIR) difference between NAP and UMPC, adjusted for entry glucose level, was 1 percentage point, with absolute TIR values of 86% (NAP) and 87% (UMPC). The two algorithms achieved similar times <70 mg/dL of 2.0% versus 1.8% and coefficients of variation of 29.3% (NAP) versus 29.1 (UMPC)%. Under identical inputs, the average absolute insulin-recommendation difference was 0.031 U/h. There were no serious adverse events on either controller. NAP had sixfold lower computational demands than UMPC. Conclusion: In a randomized crossover study, a neural-network encoding of a complex model-predictive control algorithm demonstrated similar performance, at a fraction of the computational demands. Regulatory and clinical doors are therefore open for contemporary machine-learning methods to enter the AID field. Clinical Trial Registration number: NCT05876273.

American Indian and Alaska Native violence prevention efforts: a systematic review, 1980 to 2018.

BACKGROUND: Violence is a serious public health concern disproportionately experienced by American Indian and Alaska Native (AIAN) people. While the burden and impact of violence may be explained by the presence of risk factors among this group, AIAN communities benefit from unique protective factors and universal strategies which may be tailored with tribal adaptations. We sought to identify and explore violence prevention strategies specific to AIAN populations. METHODS: A review was conducted to systematically identify violence prevention programs, policies, and practices implemented in AIAN communities. We searched nine electronic databases and relevant gray literature released between January 1980 and June 2018. We included intervention-focused records targeting at least one violence topic area (child abuse/neglect, elder abuse, intimate partner violence, sexual violence, youth violence, and suicide) in a majority (> 50%) AIAN population. RESULTS: A total of 5220 non-duplicate records were screened, yielding 318 full-text records. After applying exclusion criteria, 57 records describing 60 program, policy, or practice implementations of 43 unique interventions were identified. All six violence types were represented, although more than half (58%; n = 25/43) focused on suicide prevention. Among suicide prevention programs, the most common strategies were identifying and supporting people at risk (80%; n = 20), teaching coping and problem-solving skills (56%; n = 14), and promoting connectedness (48%; n = 12). Two-thirds of the implementations (67%; n = 40/60) were in fully (100%) AIAN communities. Programs were implemented across many settings, though schools were the most common (35%, n = 21/60) setting. Of the 60 total implementations, a majority (80%; n = 48) were new approaches developed by and for AIAN communities, while the remainder were AIAN adaptations of programs previously created for non-AIAN populations. Most implementations (60%; n = 36/60) provided some evaluation data although less than half (45%; n = 27/60) reported evaluation results. CONCLUSIONS: This review identified many violence prevention strategies specific to AIAN populations. While programs developed in one tribe may not be completely generalizable to others, shared tribal risk and protective factors suggest programs could be successful across diverse communities. Findings indicate there is a need to develop and evaluate violence prevention programs, policies and practices for AIAN populations.

An Evaluation of Messages to Promote Parental Intent to Vaccinate Children Aged <12 Years Against COVID-19.

OBJECTIVES: Effective health communication can increase intent to vaccinate. We compared 8 messages that may influence parents' intent to vaccinate their children against COVID-19. METHODS: In a cross-sectional survey of adults in the United States administered online in August 2021, 1837 parents and legal guardians were exposed to 8 messages (individual choice, gain/practical benefits, nonexpert, health care provider recommendation, altruism/community good, safety/effectiveness, safety, and effectiveness) to determine message reception and influence on intent to vaccinate their children. Parents responded to 10 questions using a Likert scale. We computed odds ratios (ORs) for each message, with an OR >1.0 indicating greater observed odds of participant agreement with the follow-up statement as compared with a reference message. We compared outcomes individually across messages with ordinal logistic regression fit using generalized estimating equations. RESULTS: The individual choice message had the highest odds of agreement for understanding intent (OR = 2.10; 95% CI, 1.94-2.27), followed by the health care provider recommendation message (OR = 1.58; 95% CI, 1.46-1.71). The individual choice message had the highest odds of memorability, relatability, and trustworthiness. The altruism/community good message was at or near second best. The altruism/community good message had the highest or near-highest odds of increasing parents' intent to vaccinate their children, asking friends and family for their thoughts, and searching for additional information. The message that most motivated parents to vaccinate their children depended on parental intent to vaccinate prior to being exposed to the tested messages. CONCLUSIONS: Messages with themes of individual choice, health care provider recommendation, and altruism/community good may be used in future message campaigns. Further research is needed to refine message concepts related to altruism/community good.
