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.

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 vs the original AID algorithm. METHODS: The UVA 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-hour 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 HbA1c 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% vs 1.8% and coefficients of variation of 29.3% (NAP) vs 29.1 (UMPC)%. Under identical inputs, the average absolute insulin-recommendation difference was 0.031 units/hour. There were no serious adverse events on either controller. NAP had 6-fold 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.

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.

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.

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.

Adolescent Sexting, Violence, and Sexual Behaviors: An Analysis of 2014 and 2016 Pennsylvania Youth Risk Behavior Survey Data.

BACKGROUND: Sexting is common among adolescents and is associated with numerous health risk behaviors and negative psychosocial constructs. This study examined the relationships between high school students' experiences with sexual violence victimization, dating violence victimization, and engagement in risky sexual behaviors with experiences of receiving sexts. METHODS: Cross-sectional data from the 2014 to 2016 data from Pennsylvania Youth Risk Behavior. Participants were selected using an independent 2-stage cluster sample design to produce a statewide population-based sample. The pencil and paper surveys were conducted in school. Participants included 6734 Pennsylvania high school students in grades 9-12. RESULTS: Overall, 29.0% of Pennsylvania high school students had received a sext, which varied by sex, race/ethnicity, school grade, and sexual identity. Students who engaged in sexual risk behaviors, experienced dating violence, or experienced lifetime sexual violence outside of the dating context had a significantly higher prevalence of receiving a sext than students who did not engage in those behaviors or have those experiences. CONCLUSIONS: Early screening and prevention efforts that include discussions about sexting behaviors may help prevent other negative outcomes, such as risky sexual behaviors and interpersonal violence. Addressing sexting in the education and health sectors may help to prevent other related harmful health and violence experiences during adolescence.

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.

Automated Insulin Delivery with SGLT2i Combination Therapy in Type 1 Diabetes.

Background: Use of sodium-glucose cotransporter 2 inhibitors (SGLT2i) as adjunct therapy to insulin in type 1 diabetes (T1D) has been previously studied. In this study, we present data from the first free-living trial combining low-dose SGLT2i with commercial automated insulin delivery (AID) or predictive low glucose suspend (PLGS) systems. Methods: In an 8-week, randomized, controlled crossover trial, adults with T1D received 5 mg/day empagliflozin (EMPA) or no drug (NOEMPA) as adjunct to insulin therapy. Participants were also randomized to sequential orders of AID (Control-IQ) and PLGS (Basal-IQ) systems for 4 and 2 weeks, respectively. The primary endpoint was percent time-in-range (TIR) 70-180 mg/dL during daytime (7:00-23:00 h) while on AID (NCT04201496). Findings: A total of 39 subjects were enrolled, 35 were randomized, 34 (EMPA; n = 18 and NOEMPA n = 16) were analyzed according to the intention-to-treat principle, and 32 (EMPA; n = 16 and NOEMPA n = 16) completed the trial. On AID, EMPA versus NOEMPA had higher daytime TIR 81% versus 71% with a mean estimated difference of +9.9% (confidence interval [95% CI] 0.6-19.1); p = 0.04. On PLGS, the EMPA versus NOEMPA daytime TIR was 80% versus 63%, mean estimated difference of +16.5% (95% CI 7.3-25.7); p < 0.001. One subject on SGLT2i and AID had one episode of diabetic ketoacidosis with nonfunctioning insulin pump infusion site occlusion contributory. Interpretation: In an 8-week outpatient study, addition of 5 mg daily empagliflozin to commercially available AID or PLGS systems significantly improved daytime glucose control in individuals with T1D, without increased hypoglycemia risk. However, the risk of ketosis and ketoacidosis remains. Therefore, future studies with SGLT2i will need modifications to closed-loop control algorithms to enhance safety.

Parents' Self-reported Changes in Concern About Children's Bullying-Fall ConsumerStyles and Estilos Surveys, United States, 2020.

Bullying is a type of youth violence and an adverse childhood experience that can result in trauma and have immediate and long-term consequences for all involved. It can happen at school or elsewhere - including online entertainment and social and learning environments. Some children are at increased risk for bullying victimization, such as those targeted because of their racial/ethnic background or cultural identity. This study assessed U.S. parents and caregivers' self-reported changes in concern about their children's involvement in bullying during Fall 2020 compared to the prior year, which was marked by extraordinary historical circumstances (e.g., COVID-19 pandemic, heightened awareness of racial inequities, schools transitioning to virtual learning). Secondary analyses of data from the 2020 Fall ConsumerStyles and Estilos online panel surveys - designed to be representative of U.S. adults overall and U.S. Hispanic adults, respectively - were conducted. Differences by children's type of school attendance (i.e., physically at school or not) and parents' sociodemographic characteristics were explored. While findings suggest that U.S. parents' concern for their children being bullied during Fall 2020 compared to the prior year did not change, significant differences were found by the children's type of school attendance and the parents' race/ethnicity - with increased concern among parents of children who physically attended school, non-Hispanic Black parents and Hispanic parents. Among parents who reported being less concerned during Fall 2020 about their children being bullied compared to the prior year, not being physically at school is noted as the main reason why. Parents who reported being more concerned frequently noted racism as the reason why. It is imperative to understand what parents think about bullying, to best inform efforts to support their key role in bullying prevention.

Exposure to a Youth-Led Sexual Violence Prevention Program Among Adolescents: The Impact of Engagement.

Objective: Most studies of peer sexual violence (SV) prevention programs for adolescents focus on program outcomes or feasibility and acceptability; few examine how exposure levels or dosage affects impact. The present study examined the effects of attending multiple community-located youth-led prevention events, as compared to attending one or none, on peer violence (PV)-related attitudes and behaviors. Method: Middle and high school students (M age at first wave = 13.7; 53.2% female; 76.5% White; 21.0% Native American) responded to surveys across 3 years. Logistic regression analyses compared students who attended one community-based event, two or more events, and zero events on sexual violence victimization, any other violence perpetration/victimization, social norms, denial of the problem of sexual violence, and bystander behaviors. Results: After controlling for exposure to longer prevention leadership training as well as baseline outcome levels, youth who participated in two or more community prevention events showed lower perpetration over time, improved prevention attitudes, and more helpful bystander actions in response to peer sexual violence. No significant differences were noted for attendance at one community-based event. Conclusions: Impact of out of school prevention events on youth behavior depends on more vigorous engagement than one-time contacts. Community-based prevention programs can utilize youth-led engagement strategies to help increase youth participation and resulting benefits.

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.

Homicides of American Indians/Alaska Natives - National Violent Death Reporting System, United States, 2003-2018.

PROBLEM/CONDITION: Homicide is a leading cause of death for American Indians/Alaska Natives (AI/ANs). Intimate partner violence (IPV) contributes to many homicides, particularly among AI/AN females. This report summarizes data from CDC's National Violent Death Reporting System (NVDRS) on AI/AN homicides. Results include victim and suspect sex, age group, and race/ethnicity; method of injury; type of location where the homicide occurred; precipitating circumstances (i.e., events that contributed to the homicide); and other selected characteristics. PERIOD COVERED: 2003-2018. DESCRIPTION OF SYSTEM: NVDRS collects data regarding violent deaths obtained from death certificates, coroner/medical examiner reports, and law enforcement reports and links related deaths (e.g., multiple homicides and homicide followed by suicide) into a single incident. This report includes data on AI/AN homicides that were collected from 34 states (Alabama, Alaska, Arizona, California, Colorado, Georgia, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, Nebraska, Nevada, New Jersey, New Mexico, New York, North Carolina, Ohio, Oklahoma, Oregon, Pennsylvania, Rhode Island, South Carolina, Utah, Virginia, Washington, and Wisconsin) and the District of Columbia. RESULTS: NVDRS collected data on 2,226 homicides of AI/ANs in 34 states and the District of Columbia during 2003-2018. The age-adjusted AI/AN homicide rate was 8.0 per 100,000 population. The homicide rate was three times higher in AI/AN males than females (12.0 versus 3.9), and the median age of AI/AN victims was 32 years (interquartile range: 23-44 years). Approximately half of AI/AN homicide victims lived or were killed in metropolitan areas (48.2% and 52.7%, respectively). A firearm was used in nearly half (48.4%) of homicides and in a higher percentage of homicides of AI/AN males than females (51.5% versus 39.1%). More AI/AN females than males were killed in a house or apartment (61.8% versus 53.7%) or in their own home (47.7% versus 29.0%). Suspects were identified in 82.8% of AI/AN homicides. Most suspects were male (80.1%), and nearly one third (32.1%) of suspects were AI/ANs. For AI/AN male victims, the suspect was most often an acquaintance or friend (26.3%), a person known to the victim but the exact nature of the relationship was unclear (12.3%), or a relative (excluding intimate partners) (10.5%). For AI/AN female victims, the suspect was most often a current or former intimate partner (38.4%), an acquaintance or friend (11.5%), or a person known to the victim but the exact nature of the relationship was unclear (7.9%). A crime precipitated 24.6% of AI/AN homicides (i.e., the homicide occurred as the result of another serious crime). More AI/AN males were victims of homicides due to an argument or conflict than females (54.7% versus 37.3%), whereas more AI/AN females were victims of homicides due to IPV than males (45.0% versus 12.1%). For homicides related to IPV, 87.2% of AI/AN female victims were killed by a current or former intimate partner, whereas approximately half (51.5%) of AI/AN male victims were corollary victims (i.e., victims killed during an IPV-related incident who were not the intimate partners themselves). INTERPRETATION: This report provides a detailed summary of NVDRS data on AI/AN homicides during 2003-2018. Interpersonal conflict was a predominant circumstance, with nearly half of all AI/AN homicides precipitated by an argument and for female victims, 45.0% precipitated by IPV. PUBLIC HEALTH ACTION: NVDRS provides critical and ongoing data on AI/AN homicides that can be used to identify effective and early intervention strategies for preventing these deaths. When possible, violence prevention efforts should include community-developed, culturally relevant, and evidence-based strategies. These efforts should incorporate traditional native knowledge and solutions, implement and possibly adapt evidence-based IPV and other violence prevention strategies, and consider the influence of historical and larger societal factors that increase the likelihood of violence in AI/AN communities.

American Indian and Alaska Native Knowledge and Public Health for the Primary Prevention of Missing or Murdered Indigenous Persons.

Violence against American Indian and Alaska Native (AIAN) women, children, two-spirit individuals,1 men, and elders is a serious public health issue. Violence may result in death (homicide), and exposure to violence has lasting effects on the physical and mental health of individuals, including depression and anxiety, substance abuse, chronic and infectious diseases, and life opportunities, such as educational attainment and employment. All communities are affected by some form of violence, but some are at an increased risk because of intergenerational, structural, and social factors that influence the conditions in communities where people live, learn, work, and play. Using a violence prevention public health approach, we discuss the role public health can play in addressing and preventing the prevalence of missing or murdered indigenous persons (MMIP).2 This paper is written as a public health primer and includes a selective overview of public health and Native public health research. It also includes case studies and Native experts' reflections and suggestions regarding the use of public health knowledge and theory, as well as Native knowledge and cultural practices to combat violence. An effective public health prevention approach is facilitated by complex, contextual knowledge of communities and people, including individual and community risk factors, as well as protective factors in strengthening Native communities and preventing MMIP. Public health promotes and protects the health of people and the communities where they live, learn, work, and play. To prevent violence, public health seeks to create safe, stable, and nurturing relationships and environments for all people. MMIP affects communities, families, and loved ones, and its victims may be women and girls, children, men, two-spirit individuals, and elders. Violence is defined as "the intentional use of physical force or power, threatened or actual, against oneself, another person, or against a group or community, that either results in or has a high likelihood of resulting in injury, death, psychological harm, maldevelopment, or deprivation."3 Violence, including adverse childhood experiences (ACEs), has a lasting impact on health, spanning injury, disease outcomes, risk behaviors, maternal and child health, mental health problems, and death.4 This paper serves as a public health primer to prevent MMIP. MMIP context is provided by weaving public health, research, and applied examples from AIAN experts, best practices in public health, and legal approaches using traditional wisdom and culture. Woven throughout the text, author perspectives are provided as applied examples to contextualize and complement the topics raised based on the individual experiences of several authors.

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.

Experiences and Correlates of Violence Among American Indian and Alaska Native Youth: A Brief Report.

The purpose of this paper is to document the scope and correlates of past 6-month victimization among American Indian (AI) and Alaska Native (AN) youth. Types of victimization under investigation included sexual assault, dating violence, bullying, sharing of nude photos, sexual harassment, homophobic teasing, and racism. Participants were 400 AI and AN youth in grades 7-10 who completed a survey in school. Results documented concerning rates of all forms of victimization among AI and AN youth during the past 6 months. Although most forms of victimization were related, bullying (at school and electronically), racism, and sexual harassment occurred more often than sexual assault and dating violence. Older youth, girls, and sexual minorities were more likely to report some forms of violence than younger youth, boys, and heterosexual youth respectively. Compared to nonvictims, victim status was consistently related to depressive symptoms, suicidal ideation, and alcohol use and was less consistently correlated with feelings of school mattering. Evidence-based, culturally grounded prevention and response efforts are needed for AI and AN youth, as well as broader initiatives that seek to reduce health disparities among AI and AN youth.
