Cross-national study of fighting and weapon carrying as determinants of adolescent injury

A Decade of Firearm Injuries: Children Caught in the Crossfire

INTRODUCTION

Firearm injuries (FIs) are the leading cause of preventable morbidity and mortality in pediatric patients. In this study, we aim to define evolving trends and avenues for prevention.

METHODS

Following institutional review board approval, medical records of patients presenting to our two State-Designated Level 1 Pediatric Trauma Centers for treatment of FIs from 2010 to 2019 were retrospectively reviewed. Data was analyzed with Chi-Squared and Student's t-test; P-value <0.05 was significant.

RESULTS

1037 FI encounters from 1005 unique patients aged 0-21 y were included. 70.4% (n = 730) were determined to be assaults, 26.1% (n = 271) unintentional, and 1.7% (n = 18) self-inflicted injuries. Overall mortality was 4.5% (n = 45). FI victims were most commonly African American (n = 836, 80.6%), male (n = 869, 83.8%), aged 13-17 (n = 753, 72.6%), and from single-parent families (n = 647, 62.4%). The incidence of FIs increased significantly over the last 5 y of the study (2010-2014, 6.8 FIs/month), compared to 2015-2019 (averaging 10.6 FIs/month, P < 0.0001). Concurrently, FI related fatality increased from an average of 2.6 deaths/year (2010-2014) to 6.4 deaths/year (2015-2019, P = 0.064). Results were subanalyzed for pediatric patients aged 0-14 y. For the entire cohort, 12.1% (n = 116) recidivists were identified. Geographic patterns of injury were identified, with 75% of all FIs clustered in a single urban region.

CONCLUSIONS

Incidence of pediatric FIs is increasing in recent years, with high mortality rates. Violence and recidivism are geographically concentrated, offering an opportunity for targeted interventions.

Exploring Firearm Access, Carriage, and Possession among Justice-Involved Youth

Firearm carriage and possession predicts youth firearm violence victimization and perpetration. This study describes self-reported factors associated with firearm access, carriage, and possession among justice-involved youth. We conducted an exploratory, mixed-methods study. Participants were recruited from May 2022 to February 2023 from the Juvenile Justice Collaborative, a diversion program for justice-involved youth. We used online anonymous surveys to investigate exposures related to firearm access, carriage, and possession. We performed semi-structured interviews using the phenomenology framework. We used descriptive statistics to examine firearm exposures by participant demographics. We performed qualitative analyses using an iterative approach with constant comparison to identify key themes. We completed 28 surveys and 5 interviews. Most survey participants identified as male (57%) and Black (61%) with a median age of 18 years. Interview participants described the socialization and cultural normalization of firearms, most prominently among peers. Survey participants reported whether they had ever carried (25%) or possessed (21%) a firearm. Survey and interview participants endorsed protection in the context of increasing violence exposure over time as the primary motivation for firearm possession. Interview participants describe accessing firearms primarily through social networks while survey participants also reported access from strangers (25%) and licensed sellers/gun dealers (18%). In conclusion, justice-involved youth believe firearm carriage and possession may be needed for protection due to increasing violence exposure. Further investigation is necessary to determine interventions that may decrease firearm access, carriage, and possession among justice-involved youth.

Association Between Child Maltreatment and Aggression in Chinese Early Adolescents: The Mediating Role of Irritability

Child maltreatment (CM) is a major global public health issue, and a strong association exists between CM and aggression. However, the underlying mechanism of this association has not been understood to date. The objective of this study was to explore the mediating role of irritability in the association between CM and aggression in Chinese early adolescents. A cross-sectional study was conducted using a self-report questionnaire to evaluate the levels of CM, aggression, and irritability in 5,724 middle school students from the Anhui Province, China. Structural equation modeling was used to test the hypothesis of the mediating effect of irritability on the relationship between CM and aggression. We further investigated gender differences in this association using multiple group analyses. CM was positively related to both irritability and aggression, and irritability was positively associated with aggression (p < .01). The mediating effects of irritability between CM and aggression were significant (β = .107, 95% confidence intervals [CI]: 0.077-0.133, p < .05). Males had a higher indirect effect size of the pathway from CM to aggression via irritability compared with females. Overall, irritability was a crucial mediator in the relationship between CM and aggression in Chinese adolescents, and males were more prone to engage in aggression compared with females through the pathway of irritability. Therefore, early irritability characteristics should be carefully monitored in adolescents, and they should be provided adequate support to acquire critical emotion regulation skills.

Correlations between weight perception and overt risk-taking among Canadian adolescents

OBJECTIVE

Perceptions of body weight represent an important health issue for Canadian adolescents. While associations between weight perception and mental health concerns like eating disorder symptomatology are well established, there is need for more Canadian evidence about how weight perception is associated with overt risk-taking among adolescents, and further how such associations differ by biological sex.

METHODS

We conducted a national analysis of grade 9-10 students participating in the 2017-2018 cycle of the Health Behaviour in School-aged Children (HBSC) study in Canada. This analysis described contemporary patterns of alternate weight perception and then examined the strength and statistical significance of such associations by biological sex, with tobacco, alcohol, and cannabis use, binge drinking, fighting, and illicit drug use as outcomes. Behaviours were considered both individually and in combination. Analyses were descriptive and analytical, with regression models accounting for the nested and clustered nature of the sampling approach.

RESULTS

Responses from 2135 males and 2519 females were available for a complete case series analysis. A total of 26% and 35% of males and females, respectively, perceived themselves as "too fat" while 20% and 9% identified as "too thin". Females perceiving themselves as "too fat" reported higher likelihoods of engaging in individual and scaled indicators of overt risk-taking. Conversely, among males, alternate weight perception was associated with lower levels of such behaviours.

CONCLUSION

As males and females perceive and react to weight perception differently, clinical and health promotion strategies should be developed and uniquely targeted to groups of adolescents in regards to weight perception and risk-taking.

Associations Between Exposure to School Violence and Weapon Carrying at School

INTRODUCTION

Among U.S. high-school students, interpersonal violence and victimizations often occur on school property. The presence of a weapon can increase the potential for injury and death resulting from interpersonal conflict. This study examines the associations between exposure to school violence and weapon carrying on school property among U.S. high-school students.

METHODS

Data from the 2017 and 2019 national Youth Risk Behavior Surveys were combined (N=28,442) and analyzed in 2022. Multivariable logistic regression models were used to calculate sex-stratified, adjusted (for race/ethnicity, grade, sexual identity, current substance use, suicidal thoughts, and history of concussion) prevalence ratios. Prevalence ratios were considered statistically significant if 95% CIs did not include 1.0.

RESULTS

Male students (4.7%) were more likely than female students (1.8%) to report carrying a weapon at school during the 30 days preceding the survey. Weapon carrying at school was more prevalent among students who were threatened or injured with a weapon at school (male students, adjusted prevalence ratio=3.45; female students, adjusted prevalence ratio=3.90), among students who were involved in a physical fight at school (male students, adjusted prevalence ratio=3.44; female students, adjusted prevalence ratio=3.72), among students who missed school because they did not feel safe (male students, adjusted prevalence ratio=1.98; female students, adjusted prevalence ratio=2.97), and among male students who were bullied at school (adjusted prevalence ratio=1.72) than among students who did not experience school violence.

CONCLUSIONS

Increased emphasis on safe and supportive school environments, where all types of interpersonal violence are less likely to occur, and increased access to programs and services to promote mental health, prevent violence, and deter weapon use are needed.

Understanding changes in aggression among U.S. army soldiers: The role of trauma exposure during deployment

Aggression is one of the leading concerns reported by United States service members and veterans. Trauma and posttraumatic stress disorder (PTSD) symptoms have emerged as key drivers of aggression. Research to date, however, has largely overlooked the effect of aggression on increasing risk of trauma exposure and subsequent PTSD. The current study addresses this gap by examining whether (a) pre-deployment aggression predicts trauma exposure on deployment and post-deployment PTSD, (b) trauma exposure on deployment and post-deployment PTSD predict post-deployment aggression, and (c) trauma exposure on deployment and post-deployment PTSD symptoms explain changes in aggressive behavior from pre-to post-deployment. Data from the Army Study to Assess Risk and Resilience in Servicemembers (Army STARRS) Pre/Post Deployment Study (PPDS) on nationally representative sample of 8558 Active-duty Army soldiers were analyzed. Results revealed positive correlations between pre-deployment aggression (assessed via items from the Joint Mental Health Advisory Team 7), trauma exposure on deployment (assessed via items from the Deployment Stress Scale), post-deployment PTSD symptoms (assessed via items from the civilian PTSD Checklist and PTSD Checklist for DSM-5), and post-deployment aggression. Further, pre-deployment aggression predicted trauma exposure on deployment and post-deployment PTSD; trauma exposure on deployment and post-deployment PTSD predicted post-deployment aggression; and changes in aggression from pre-to post-deployment were partially mediated by trauma exposure on deployment and post-deployment PTSD symptoms. Collectively, these findings highlight the utility of identifying and addressing pre-deployment aggression in mitigating trauma exposure and later psychopathology.

Muscle-Building Exercise and Weapon Carrying and Physical Fighting Among U.S. Adolescent Boys

This study aimed to determine the association between engagement in muscle-building exercise and weapon carrying and physical fighting among adolescent boys. Cross-sectional data from the 2019 Youth Risk Behavior Survey (U.S.) were analyzed (N = 4120). Muscle-building exercise was assessed based on the number of days reported in the past 7 days, recategorized into four levels of engagement (no engagement [0 days], low engagement [1-2 days], moderate engagement [3-5 days], and high engagement [6-7 days]). Three forms of weapon carrying (general, on school grounds, gun carrying) and two forms of physical fighting (general, on school grounds) were assessed. Five logistic regression analyses with adjusted odds ratios (AOR) and 95% confidence intervals (CI) were used to determine the association between engagement in muscle-building exercise and weapon carrying and physical fighting, while adjusting for relevant demographic and control variables. Over 75% of participants reported engaging in muscle-building exercise. One in five (19.8%) participants reported any general weapon carrying in the past 30 days, 3.3% reported any weapon carrying at school in the past 30 days, 6.5% reported any gun carrying in the past 12 months, 28.0% reported any general physical fighting in the past 12 months, and 10.7% reported any physical fighting at school in the past 12 months. Logistic regressions showed that, compared to no engagement, participants who reported high engagement of muscle-building exercise had higher odds of general weapon carrying (AOR 2.18, 95% CI 1.54-3.07), gun carrying (AOR 2.12, 95% CI 1.23-3.64), and general physical fighting (AOR 2.07, 95% CI 1.53-2.79). These are novel findings that add to a growing literature related to engagement in muscularity-oriented behaviors among males. Prevention and intervention efforts are needed to ensure that adolescent boys engage in muscle-building exercise in ways that are not harmful and to reduce weapon carrying and physical fighting.

Psychological profiles, including emotion regulation characteristics, defence strategies and mentalisation capacity, of male adolescents involved in fights among peers

BACKGROUND

Youth violence has become a worrying public health issue worldwide. In Europe and the USA, research has shown a prevalence of this phenomenon ranging from 30 to 70% in boys.

AIMS

This descriptive study aimed to evaluate psychological profiles of male adolescents involved in fights with their peers.

METHOD

Identity consolidation was evaluated with the Self-Concept and Identity Measure; defence strategies were assessed by the Response Evaluation Measure for Youth; emotion regulation was assessed with the Difficulties in Emotion Regulation Scale and mentalisation capacity was evaluated by the Reflective Functioning Questionnaire.

RESULTS

Through a series of multivariate analyses of variance, our results showed that adolescents reporting four or more fights in the past year, when compared with peers reporting none or fewer than four fights, displayed lower identity consolidation, greater use of immature defence strategies, poorer emotion regulation processes and poorer mentalisation capacity.

CONCLUSIONS

The results of this study could be useful for the promotion of prevention and intervention programmes to stem fights among adolescents.

Understanding factors associated with firearm possession: Examining differences between male and female adolescents and emerging adults seeking emergency department care

Firearm possession increases the likelihood of hospital visits among adolescents and emerging adults for both males and females. To better inform prevention practices, we examine data among adolescents and emerging adults (A/EAs; ages 16 to 29) presenting to an urban emergency department for any reason to understand the differences in firearm possession between males and females (N = 1312; 29.6% male; 50.5% Black). Regression identified firearm possession correlates, such as male sex (AOR = 2.26), firearm attitudes (AOR = 1.23), peer firearm possession (AOR = 9.84), and community violence exposure (AOR = 1.02). When stratified by sex (e.g., male vs female), regression results yielded differences in correlates for firearm possession: in males, peer firearm possession (AOR = 8.96) were significant, and in females, firearm attitudes (AOR = 1.33) and peer firearm possession (AOR = 11.24) were significant. An interaction between sex and firearm attitudes demonstrated that firearm attitudes were differentially associated with firearm possession between female and male A/EAs (AOR = 1.28). Overall, we found that females are more likely to endorse retaliatory firearm attitudes, and both males and females are highly influenced by their perception of peer firearm possession. These results help inform prevention strategies across multiple settings, especially for hospital-based violence interventions, and suggest that tailored approaches addressing differences between male and female A/EAs are appropriate when addressing firearm violence and injury risk among A/EAs.

Youth gun carrying and household firearm ownership in 22 US states

Youth gun carrying is associated with a range of adverse outcomes, including increased risks for homicide, suicide, school disciplinary problems, and criminal legal involvement. In this study we examined the association between state-level household firearm ownership rates and the odds of past-year gun carrying among high-school-aged youth. Using survey-weighted multivariable logistic regression models, results showed that each 1% point increase in state-level gun ownership was associated with a 2.7% (95% confidence interval [CI] = [1.1%, 4.2%], p = 0.001) increased odds of youth gun carrying, controlling for histories of school-based victimization, physical fighting, and substance use. Among a subset of weapon-carrying youth, state-level firearm availability was a significant factor in determining whether the weapon carried was a gun or a less lethal (i.e., nonfirearm) weapon (odds ratio = 1.021, 95% CI = [1.005, 1.038], p = 0.01). These findings show that firearm availability confers additional risk for youth gun carrying beyond the psychosocial risks emphasized in prior research and efforts to restrict youth access to firearms might be particularly important, especially in communities with high levels of household gun ownership.

Weapon Carrying and Weapon Brandishing at School: Responses to Strain Among Same-Sex Attracted Youth

Studies consistently find lesbian, gay, bisexual, and questioning youth are more likely than other youth to experience discrimination, fear for their safety, and be victimized at school. We argue that same-sex attracted youth may be more likely to both carry weapons and to brandish those weapons as coping mechanisms in response to the strain of real or perceived mistreatment school. Using data from the National Longitudinal Study of Adolescent to Adult Health (Wave 1, 1994-1995), we examine the relationships between same-sex attraction, fear, victimization, weapon carrying, and weapon brandishing at school. We find that same-sex attracted youth are significantly more likely than other youth to carry a weapon to school, and to brandish the weapon in front of peers. Consistent with general strain explanations, victimization, discrimination, and fear mediate the association between sexual minority status and both outcomes. We discuss the implications of these patterns for primary prevention interventions.

The association between perceived community violence, police bias, race, and firearm carriage among urban adolescents and young adults

Firearms are a leading cause of death among youth and young adults. Given community violence is an important correlate of youth firearm carriage, we evaluated: 1) If the association between perceived community violence and firearm carriage is stronger when perceived police bias is greater; and 2) If this moderated association differs by race. Cross-sectional data came from screening data for a longitudinal study of firearm behaviors among young adults seeking urban emergency department treatment between July 2017-June 2018 (N = 1264). We estimated Poisson regressions with robust error variance to evaluate associations between perceived community violence, police bias, race, and firearm carriage. Community violence was positively associated with firearm carriage (average marginal effect [AME]: 0.05; 95% Confidence Interval [CI]: 0.03, 0.07). We also found that the positive association between community violence and firearm carriage increased with higher perceptions of police bias (interaction p < 0.05). We did not find evidence of a three-way interaction by which the moderated association between violence exposure and firearm carriage by perceived police bias varied by race of the respondents. Our findings suggest that community-level strategies to reduce violence and police bias may be beneficial to decrease youth firearm carriage in socio-economically disadvantaged urban settings.

A Within-Individual Examination of the Predictors of Gun Carrying During Adolescence and Young Adulthood Among Young Men

Although prior studies have identified several risk factors for gun carrying, no prior longitudinal studies have examined a comprehensive set of explanatory factors together in within-individual change models or examined whether the predictors of gun carrying change across adolescence and early young adulthood. The present study fills these gaps by examining the predictive utility of several risk factors for gun carrying, and by examining whether any of the associations vary by age. The sample included 1216 young men who were arrested for the first time during adolescence (approximately 15 years old) and interviewed regularly for 5 years (until approximately 20 years old) after the first arrest. The outcome was youth-self-reported gun carrying and the risk factors included several variables consistent with various explanations for gun carrying (psychosocial maturity deficits; antisocial behavioral style; socialization; victimization). Research questions were addressed with fixed effects dynamic panel models (within-individual change models). Results showed that the most robust predictors of gun carrying were increased exposure to guns and gun-related violence and increased engagement in other antisocial and illegal behavior. The results emphasize the specific etiology of gun carrying and the potential social contagion effect of gun-related events. Overall, the study points to the need for prevention and intervention programs to specifically target the reduction of the real and perceived prevalence of gun-related events in young men's lives.

Children's exposure to trafficking, sexual exploitation and community-based violence in Canada: A narrative summary and policy perspective

BACKGROUND

Given the formidable health burdens associated with children's exposure to community-based violence (CBV) and trafficking and exploitation (TE), continued investments in determining their epidemiology constitute an important focus for Canada.

OBJECTIVE

The objective of the present study is to provide a narrative summary and policy perspective concerning the quantitative studies reporting on the risk and protective factors and prevalence of children's (<18 years) exposure to CBV and TE in Canada.

METHODS

To identify literature, we searched eight electronic databases. English and French citations from database inception to December 2018 were included; this was supplemented with citation chaining for peer-reviewed publications and grey literature up to December 2019. Evidence is synthesized via a narrative summary.

RESULTS

There are few studies that have investigated children's exposure to TE and CBV in Canada. Self-reported exposure to these forms of violence varies according to the type investigated, with estimates ranging from 2 % - to - 23 % and 5 % - to - 53 % for TE and CBV, respectively. Literature focused on risk and protective factors for these forms of victimization are also limited.

CONCLUSIONS

Canada has the infrastructure in place to make significant gains in their data collection and monitoring of children's exposure to TE and CBV via five national-level studies. To help realize the goal of ending all forms of violence against children by 2030, incorporation of reliable measures of these forms of exposure in new and ongoing national-level data collection systems is urgently needed.

Age at first alcohol use and weapon carrying among adolescents: Findings from the 2019 Youth Risk Behavior Survey

BACKGROUND

Although studies have investigated the association between alcohol use and violent behaviors such as weapon carrying, few studies have examined the association between age at first alcohol use and weapon-carrying among adolescents. The objective of this study was to investigate the association between age at first alcohol use and weapon carrying among adolescents.

METHODS

Data for this study came from the 2019 Youth Risk Behavior Survey. An analytic sample of 13,442 adolescents aged 14-18 years old (51% female) was analyzed using binary logistic regression. The outcome variable investigated in this study was weapon carrying during the past 30 days, and the main explanatory variable investigated was age at first alcohol use.

RESULTS

Of the 13,442 adolescents, 13.5% carried a weapon during the past 30 days, and 15.4% reported having their first alcoholic drink before age 13. In the multivariable logistic regression, adolescents who reported having alcohol before age 13 had more than double the odds of carrying a weapon when compared to those who never had alcohol before age 13 (AOR = 2.32, p < .001, 95% CI = 1.87-2.89). Other significant factors associated with weapon carrying include male gender, victim of bullying, teen dating violence, sexual violence, suicidal ideation, and history of substance use. Adolescents who self-identified as Black/African American or Hispanic were significantly less likely to carry a weapon when compared to adolescents who self-identified as non-Hispanic White.

CONCLUSION

The findings of this study underscore the importance of developing age appropriate intervention strategies to curb early initiation of alcohol use and weapon carrying among adolescents.

Associations Between Children's Physical Activity, Pain and Injuries

Our aim in this study was to investigate the relationships between physical activity (PA), pain, and injury among children. Secondarily, we examined whether these relationships differed between children with normal versus excessive weight or obesity. This was a cross-sectional study of 102 children (57 girls) aged 8–12 years old. We assessed the prevalence of moderate and vigorous PA using accelerometry over a seven-day period. We examined the associations between moderate PA, vigorous PA, pain presence, and injury presence using generalized estimating equations with a logit link and binomial distribution. We adjusted the obtained models for potential confounders and explored the moderating effect of weight status. We found no association between moderate PA and pain, but time spent in vigorous PA was associated with pain. Neither moderate or vigorous PA were associated with injury, and there was no moderating effect of weight status in these relationships. In summary, we found that objectively measured vigorous PA is associated with pain among 8–12 year old children. While these results should be replicated in longitudinal studies, they suggest that an association between vigorous PA and pain should be considered when developing PA interventions for children.

Addressing Key Gaps in Existing Longitudinal Research and Establishing a Pathway Forward for Firearm Violence Prevention Research

The main purpose of this article and this special section is to encourage greater attention to the key gaps that exist in our understanding of the epidemiology of adolescent firearm violence and to provide a pathway forward for future longitudinal research that will inform prevention efforts. This increased attention is especially salient given: (a) firearms are the leading cause of death for adolescents and emerging adults in the United States, with the majority of these deaths due to interpersonal violence; (b) significant health and social disparities with regards to the populations that are most affected by interpersonal firearm violence have been documented; and, (c) limitations in federal research funding during the past 30 years have created a deficit of knowledge about key risk and protective factors necessary to inform evidence-based prevention efforts. We discuss the implications of the articles in this special edition for existing and novel prevention programs. We also identify key considerations for future epidemiological research, including the need for a greater focus on collecting longitudinal data among nationally representative samples enriched with subgroups of at-risk youth, the need to examine the role of protective factors and mediating variables within existing and novel theoretical models of firearm risk behaviors, the need to examine key factors across all levels of the socio-ecological model, and the need to incorporate novel and innovative research designs, methods and analyses.

Violence, Adolescence, and Canadian Religious Communities: A Quantitative Study

Exposure to violence is recognized as a major health concern among adolescent populations. The evidence base that links religious involvement with risks for child violence is inconsistent. In a national analysis involving a weighted sample of 24,307 young people, we studied the perpetration of violence (fighting and bullying), as well as victimization by violence (bullying only), among young people who were affiliated with religious groups. One in four young Canadians reported involvement in such groups. Study findings confirmed some unique patterns among this group. First, these religiously involved children reported the same or greater levels of perpetration of violence than other children. Second, religiously involved children reported the same or greater levels of experiencing victimization from violence. Third, religious involvement appeared to protect against engagement in certain overt risk-taking behaviors, but not violence. These patterns were consistent even after adjustment for family, community, socioeconomic, and school-related determinants. If religious communities are to fulfill mandates that foster the protection and nurturing of children into healthy relationships, violence is best addressed using evidence-based strategies. Development of such effective preventive strategies requires the incorporation of contemporary evidence about the distribution, determinants, and possible effects of violence in such groups. Findings from our study suggest that a silence around the issue of violence may in fact be true in the context of some Canadian religious communities. Yet, if these communities make an intentional commitment to protecting children from violence and promoting healthy relationships, and are willing to learn from evidence-based practices that have shown to protect children from participating in and experiencing violent and victim behaviors, perhaps these disturbing trends could be reversed. This message is germane for all levels of leadership in Canadian religious communities.

Association between nutritional intake and aggressive behaviors in children and adolescents: The CASPIAN-IV study

OBJECTIVE: This study aims to explore the association of nutritional intake and aggression among a nationally representative sample of Iranian children and adolescents. METHODS: This nationwide cross-sectional study was conducted on a multi-stage sample of 14880 students, aged 6–18 years, living in 30 provinces in Iran. Parents were asked to report the dietary intake of their children as frequency of food groups and/or items. The validated questionnaire of the World Health Organization-Global School-based Health Survey (WHO-GSHS) was used to measure components related to aggression including physical fight, verbal aggression, and being bullied by other students. RESULTS: Participants consisted of 13486 students (90.6% participation rate) with mean age of 12.47 years (95% CI: 12.40, 12.54); 49.2% were girls, and 75.6% lived in urban areas. Physical fighting was more prevalent among urban boys[(48.63%), CI (46.75, 50.5)] while bulling was the most common aggressive behavior among boys [(29.7%), CI (28.03, 31.42)] and girls [(25.26%), CI (23.66, 26.93)] living in urban areas. Daily consumption of fast foods, sweets, soda, salty snacks and fried foods was higher among those participants who reported frequent experience of physical aggression and bullying. Bullying to others increased significantly with consumption of fast food (Odds ratio: 1.43, CI: 1.07, 1.92) and red meat (Odds ratio: 1.14, CI: 1.02, 1.28). Salty snack consumption showed a significant association with physical fighting (Odds ratio: 1.29, CI: 1.15, 1.44). CONCLUSION: The findings of this study suggest that some unhealthy foods might affect the mental health of children and adolescents. Improving dietary habits should be considered for prevention of violence in the vulnerable pediatric age group.

Non-apnea sleep disorder and its risk for all kinds of injuries: A 14-year follow-up for a nationwide population-based retrospective study

Non-apnea sleep disorder (NASD) increases the risk of motor vehicle accidents. However, systemic review of NASD and its risk for all causes of injury is lacking. The aim of the present study was to provide a detailed demographic data on NASD and all causes of injury in a 14-year follow up.Our study utilized outpatient and inpatient data from the Longitudinal Health Insurance Database between 2000 and 2013 in Taiwan. We enrolled 989,753 individuals aged ≥20 years who were diagnosed with NASD as outpatients ≥3 times or inpatients ≥1 time. We matched the study cohort with a comparison cohort by age, index date and comorbidities at a ratio of 1:4. We used Cox proportional hazards regression to analyze the association of NASD and the cause of injury.In this 14-year follow up study, patients with NASD had 12.96% increased risk of injury compared to that of the control cohort. Fall was the first place of the cause of injury with 670.26 per 105 PYs. In the stratified age group, patients aged ≧65 years had the highest risk of injury (adjusted HR= 1.381; P < .001). Kaplan-Meier analysis showed that the incidence of injury between the with- and without-NASD cohorts started from the first year and persisted until the end of the follow-up.Our study demonstrates that NASD patients were associated with higher risk of all causes of injuries, with falling being the most prevalent diagnosis. The general public should be more aware of this neglected issue of NASD.

Physical violence and associated factors in participants of the National Student Health Survey (NSHS)

The objective of this article was to analyze the association between physical violence in students with socioeconomic factors, family context, mental health, individual risky behaviors, and unsafe environment. Study with data from the National School Health Survey (NSHS) in 2015, with 9th graders. The outcome variable was the report of involvement in a physical struggle and the associated exposure variables used were related to socioeconomic and demographic conditions, family supervision and support, mental health, risky behaviors, and unsafe environment. Multivariate logistic regression with a hierarchical approach was used in the analyzes. The prevalence of involvement in a fight was higher in boys (30.2%; CI 29.3-31.0) than in girls (16.7%; CI 16.0-17.4). In both genders, there was a greater chance of involvement with physical violence when using drugs, missing classes, sedentary lifestyle, insomnia, loneliness and insecurity at school or in the community and, especially, when victimized by family aggression, OR 2.59 (CI 2.31-2.90) in boys and girls OR 2.42 (CI 2.17-2.71). There was a reduction in the chance of involvement in physical violence in boys because they were working and, in girls, when they study in a private school, having their problems and concerns welcomed by their parents or their participation in school activities.

Medically Attended Injuries among Slovak Adolescents: Relationships with Socio-Economic Factors, Physical Fighting, and Physical Activity

There is a worrisome increase in the reporting of medically attended injuries in Slovak adolescents. The aim of this study is to examine the relationships between socio-economic factors, physical fighting, and physical activity with frequency of medically attended injuries among this population group. Data from 8902 adolescents participating in the Health Behavior in School-Aged Children study were used (mean age 13.37; 50.9% boys). The effects of family affluence, registered unemployment rate, average nominal monthly earnings of employees, physical fighting, and physical activity on frequency of medically attended injury were explored using linear regression analysis. Pearson's correlation was used to describe the associations between all selected variables. The selected model of linear regression explained 15.8% of the variance in the frequency of medically attended injuries. All variables except the registered unemployment rate showed linear positive relationships with medically attended injuries. The correlation analysis confirmed linear positive associations between medically attended injuries and physical fighting, family affluence, physical activity, and average nominal monthly earnings of employees. Further research on these variables is needed in the Slovak context. This may include analyses of the nature of the relationships between socio-economic factors and medically attended injuries, as well as systematic evaluation of applied physical fighting and physical-activity-related injury interventions to support evidence-based policy making.

Within-Person Variability in Firearm Carriage Among High-Risk Youth

INTRODUCTION

Youth who carry firearms-and peers that surround them-are at increased risk for violent injuries. Because firearm carriage behaviors can change over time within an individual, it is important to identify individual and social-contextual determinants that explain this within-person variability in carriage.

METHODS

The authors identified individual and social-contextual determinants of firearm carriage in the past 6 months using multilevel logistic models on 5 waves of panel data from the Flint Youth Injury Study (n=597; ages 14-24 years), collected in 2009-2011 and analyzed in 2019.

RESULTS

Regarding within-person effects, when an individual had more positive peer affiliations than their average, their odds of carrying a firearm decreased (OR=0.88; 95% CI=0.81, 0.96). Conversely, an individual's odds of carrying a firearm increased when they had more negative peer affiliations (OR=1.08, 95% CI=1.02, 1.14), experienced more victimization (OR=1.03, 95% CI=1.01, 1.05), perceived greater community violence (OR=1.12, 95% CI=1.05, 1.21), or exhibited greater retaliatory attitudes (OR=1.10, 95% CI=1.01, 1.19) than their average.

CONCLUSIONS

Peer affiliations, victimization, community violence perceptions, and retaliatory attitudes explain within-person variability in firearm carriage. Strategies for reducing carriage among youth should consider individual- and environmental-level interventions to address these individual and social-contextual determinants.

Dynamic Risk Factors for Handgun Carrying: Are There Developmental or Sex Differences?

Objective: This study examines the effects of dynamic risk factors on handgun carrying from adolescence into young adulthood.Method: A nationally representative sample of 8,679 individuals (ages 12-26; 51.1% male; 58% White, 26.8% African American; 21.2% Hispanic ethnicity) from the National Longitudinal Survey of Youth (1997 cohort) interviewed at least three times across nine annual waves is used to estimate effects on handgun carrying. Key predictors include gang membership, selling and using drugs, violent crime, and arrest. Using mixed effects models, we focus on within-individual effects across three timeframes from ages 12 to 26: 1) predictors and handgun carrying measured concurrently, 2) predictors measured across one year and handgun carrying measured in the final month of the same year, and 3) predictors measured in the wave before handgun carrying. We also contrast estimates by sex and age.Results: All theoretically relevant predictors statistically significantly predict handgun carrying across the first two timeframes. However, none are statistically significant predictors of handgun carrying in the following year. Few significant sex and age differences emerge.Conclusions: Handgun carrying is an ephemeral behavior particularly during adolescence. The predictors of handgun carrying, which are grounded in gangs, drug use/sale, and crime involvement, appear to have short-term impacts that are consistent across age as well as across sex. Consequently, future work should focus on shorter-term changes in models and there is no evidence that intervention efforts must take fundamentally different approaches to reduce handgun use among males versus females or adolescents versus adults.

Gender and Sexual Orientation Bullying Victimization are Associated with Gun Carrying Among Adolescent Boys

Gun carrying and bullying victimization are associated among adolescent boys, however the type of the bullying remains relatively unknown. This study aimed to identify whether experiencing bullying victimization based on gender and sexual orientation is associated with carrying a gun to school among adolescent boys. A cross-sectional analysis among a representative sample of high school boys (n = 3672) from the 2015 Maine Integrated Youth Health Survey was conducted. Odds ratios (OR) and 95% confidence intervals (CI) were obtained using logistic regression analyses while controlling for grade level, race/ethnicity, sexual orientation, suicidal ideation, alcohol and marijuana use, and gun access. Among the sample, 3.3% reported carrying a gun to school at least one time in the previous 12-months, 9.5% reported experiencing gender-based bullying victimization, and 7% reported experiencing sexual orientation-based bullying victimization. Regression analyses indicated that adolescent boys who experienced gender-based bullying victimization (OR 3.40, 95% CI 1.64, 5.62, p < .001) or sexual orientation-based bullying victimization (OR 3.57, 95% CI 1.91, 6.67, p < .001) had greater odds of reporting they carried a gun to school while controlling for grade level, race/ethnicity, sexual orientation, suicidal ideation, alcohol and marijuana use, and gun access. These results expand upon previous gun carrying and bullying research by identifying the specific type of the bullying experienced and have important implications for social workers and school personnel. Importantly, these results emphasize the need to address two of the Grand Challenges for Social Work: building healthy relationships to end violence and ensuring the healthy development for all youth.

Extent, patterns and demographic correlates for physical fighting among school-attending adolescents in Namibia: examination of the 2013 Global School-based Health Survey

Background

Physical fighting is particularly detrimental for young people, often affecting other areas of their developing lives, such as relationships with friends and family and participating in risky behaviors. We aim to quantify the amount of problematic physical fighting in Namibian adolescents and identify modifiable risk factors for intervention.

Methods

We used the Namibia 2013 Global School-based Student Health Survey (GSHS). This survey collects health-related information on school-attending adolescents in grades 7 to 12. We defined physical fighting as having participated in at least two physical fights in the 12 months prior to responding to the survey. Factors that may be associated with physical fighting were identified a prior based on the literature and included age, sex, anxiety, suicide planning, truancy, physical activity, bullying victimization, presence of supportive parental figures, presence of helpful peers, extent of social network, and food insecurity. Multivariable logistic regression models were created to identify factors associated with physical fighting.

Results

A total of 4,510 adolescents were included in the study. A total of 52.7% female. 16.9% of adolescents reported engaging in at least two physical fights in the previous year. Factors associated with an increased odds of physical fighting included having a suicide plan, anxiety, truancy, food deprivation and being bullied. Increased age and loneliness were associated with a decreased odds of physical fighting.

Conclusion

This study identifies problematic physical fighting among adolescents in Namibia. We recommend public health and school-based programming that simultaneously targets risk behaviours and conflict resolution to reduce rates of physical fighting.

Physical Fighting among School-Attending Adolescents in El Salvador: An Examination of the 2013 Global School-Based Health Survey

Background: Violence among school-attending adolescents is an important public health problem worldwide. The present study examined demographic correlates for physical fighting behavior among a nationally representative sample of school-attending adolescents in El Salvador. Methods: Initial cross-tabulations to screen for correlations was then followed by logistic regression to understand the direction and the strength of selected demographic variables for physical fighting behavior, which occurred within a 12 month period of recall. Results: Out of a sample of 1910 school-attending adolescents in El Salvador, 11.5% reported having been involved in two or more physical fights during the recall period. Regression analyses indicated that being male (OR = 3.55; 95% CI = 2.11-6.00); having experienced bullying (OR = 2.16; 95% CI = 1.44-3.24); physical activity (OR 0.61; 95% CI 0.46-0.80); a sedentary lifestyle (OR 1.54; 95% CI 1.05-2.27), suicide planning (OR 2.28; 95% CI 1.46-3.56), and having non-understanding parents (OR = 1.45; 95% CI 1.06-1.98) were significantly associated with physical fighting among the sampled adolescents. Conclusion: Within the limitations of cross-sectional surveys conducted in school settings, the results of the present study suggest that giving attention to preventing bullying behavior among males and involving parents should be components of a multi-pronged strategy to preventing physical fighting in schools in El Salvador.

Sleep duration, handgun carrying, and taking a handgun to school: an analysis of a statewide sample of Florida youth

OBJECTIVES

To investigate whether sleep duration is associated with adolescent handgun carrying behaviors.

DESIGN

The Florida Youth Substance Abuse Survey (FYSAS) is a cross-sectional study of adolescents.

SETTING

The state of Florida.

PARTICIPANTS

Middle school and high school students (n = 42,182) attending public schools in 2018.

METHODS

Dichotomous measures of general handgun carrying and taking a handgun to school within the past 12 months were modeled as dependent variables. Self-reports of hours slept on an average school night were used to construct multiple indicators of sleep duration (ordinal, dichotomous, and hourly dummy variable series) to predict general handgun carrying and taking a handgun to school in logistic regression models when accounting for several covariates.

RESULTS

Adjusting for model covariates, youth who reported sleeping four or fewer hours at night had 40% greater odds of general handgun carrying than youth who reported sleeping eight or more hours. Likewise, youth who reported sleeping four or fewer hours at night had 85% greater odds of taking a handgun to school than youth who reported sleeping eight or more hours. Youth who reported sleeping five, six, or seven hours were no more likely to report handgun-carrying behaviors than youth who reported sleeping eight or more hours.

CONCLUSIONS

Among youth in Florida, severe deficits in sleep are associated with general handgun carrying as well as taking a handgun to school. More modest sleep deficits are not associated with these behaviors.

As Violence Unfolds: A Space-Time Study of Situational Triggers of Violent Victimization among Urban Youth

OBJECTIVES

This study clarifies three important issues regarding situational or opportunity theories of victimization: 1) whether engaging in risk activities triggers violent assault during specific, often fleeting moments, 2) how environmental settings along individuals' daily paths affect their risk of violent assault, and 3) whether situational triggers have differential effects on violent assault during the day versus night.

METHODS

Using an innovative GIS-assisted interview technique, 298 young male violent assault victims in Philadelphia, PA described their activity paths over the course of the day of being assaulted. Case-crossover analyses compared each subject's exposure status at the time of assault with his own statuses earlier in the day (stratified by daytime and nighttime).

RESULTS

Being at an outdoor/public space, conducting unstructured activities, and absence of guardians increase the likelihood of violent victimization at a fine spatial-temporal scale at both daytime and nighttime. Yet, the presence of friends and environmental characteristics have differential effects on violent victimization at daytime versus nighttime. Moreover, individual risk activities appeared to exhibit better predictive performance than did environmental characteristics in our space-time situational analyses.

CONCLUSIONS

This study demonstrates the value of documenting how individuals navigate their daily activity space, and ultimately advances our understanding of youth violence from a real-time, real-life standpoint.

Rates and correlates of risky firearm behaviors among adolescents and young adults treated in an urban emergency department

Firearm violence is a leading cause of death for urban adolescents and young adults (A/YAs). Little is known about patterns of risky firearm behaviors (RFBs) that may increase firearm-related fatality and non-fatal injury risk. To inform prevention efforts, we examined the rates and correlates of RFBs, including firearm carriage in risky situations (e.g., while drunk/high), discharge in risky situations (e.g., fleeing police), and firearm aggression (e.g., firearm threats/use against a partner/non-partner), among a sample of A/YAs (age-16-29) seeking medical or injury related care (7/2017-6/2018) at a Level-1 urban Emergency Department (ED). In total, 1312 A/YAs completed the survey (mean-age 23.2; 29.6%-male; 50.5%-Black; 56.3%-public assistance), with 102 (7.8%) engaging in RFBs. Among those engaging in RFBs, 42% reported firearm ownership, 68.6% firearm carriage in high-risk situations, 39.2% firearm discharge in risky situations, and 41.2% reported partner/non-partner firearm aggression. Regression identified RFBs correlates, including older age (AOR = 1.09), male sex (AOR = 1.63), Black race/ethnicity (AOR = 2.01), substance misuse (AOR = 2.75), attitudes favoring firearm use/retaliation (AOR = 1.38), peer firearm ownership/carriage (AOR = 3.26), higher levels of community violence exposure (AOR = 1.05), and active parole/probation (AOR 2.38). Higher coping skills were protective for RFBs (AOR = 0.83). Overall, we found that A/YAs seeking urban ED treatment reported elevated RFB rates, emphasizing the need for novel prevention initiatives, especially those incorporating tailored content addressing substance use, retaliatory violence, and peer delinquency/norms, while enhancing self-efficacy for avoiding RFBs and providing access to external resources within a resiliency-based framework. Such prevention approaches may be a critical step towards addressing the public health problem of firearm violence. Primary Funding Sources: NIH/NIDA K23DA039341; NIH/NCATS UL1TR000433.

Weapon-carrying is associated with more permissive gambling attitudes and perceptions and at-risk/problem gambling in adolescents

BACKGROUND AND AIMS

A recent call to action highlighted the need to understand the relationship between problem gambling, violence, and health/functioning. As weapon-carrying and gambling behaviors are prevalent in adolescents, this study systematically examined relationships between weapon-carrying status and measures of problem gambling severity and gambling perceptions and attitudes, as well as how weapon-carrying status moderated relationships between problem gambling severity and measures of health/functioning and gambling behavior.

METHODS

Participants were 2,301 Connecticut high-school adolescents. χ² and logistic regression models were conducted.

RESULTS

Weapon-carriers reported greater problem gambling severity, more permissive gambling perceptions, greater parental approval of gambling, and more family gambling concerns, compared to non-weapon-carriers. At-risk/problem gambling was more strongly associated with family, peers, and adult gambling partners among non-weapon-carriers (vs. weapon-carriers) and with machine gambling among weapon-carriers (vs. non-weapon-carriers).

DISCUSSION AND CONCLUSIONS

Greater problem gambling severity and more permissive gambling perceptions and perceived parental approval of gambling in weapon-carrying adolescents suggest that parent-child relationships are important to be considered in prevention efforts. The moderated relationship by weapon-carrying status between problem gambling severity and gambling partners suggests a problem gambling risk group that may be less linked to gambling with traditional social support groups, and this group may benefit from targeted interventions.

A scoping review of patterns, motives, and risk and protective factors for adolescent firearm carriage

Firearm carriage is a key risk factor for interpersonal firearm violence, a leading cause of adolescent (age < 18) mortality. However, the epidemiology of adolescent firearm carriage has not been well characterized. This scoping review examined four databases (PubMed; Scopus; EMBASE; Criminal Justice Abstracts) to summarize research on patterns, motives, and underlying risk/protective factors for adolescent firearm carriage. Of 6156 unique titles, 53 peer-reviewed articles met inclusion criteria and were reviewed. These studies mostly examined urban Black youth, finding that adolescents typically carry firearms intermittently throughout adolescence and primarily for self-defense/protection. Seven future research priorities were identified, including: (1) examining adolescent carriage across age, gender, and racial/ethnic subgroups; (2) improving on methodological limitations of prior research, including disaggregating firearm from other weapon carriage and using more rigorous methodology (e.g., random/systematic sampling; broader population samples); (3) conducting longitudinal analyses that establish temporal causality for patterns, motives, and risk/protective factors; (4) capitalizing on m-health to develop more nuanced characterizations of underlying motives; (5) increasing the study of precursors for first-time carriage; (6) examining risk and protective factors beyond the individual-level; and, (7) enhancing the theoretical foundation for firearm carriage within future investigations.

Examining the Association between Weapon Carrying on School Property and Suicide Attempt among Adolescents in the United States

Suicidal behaviors among adolescents in the United States are the second leading cause of death and has been steadily increasing over the years. Although access to and possession of a weapon may facilitate the transition from suicidal ideation to a suicide attempt, few studies have examined the association between weapon carrying and suicide attempts among adolescents. The objective of this study was to examine the association between weapon carrying on school property and suicide attempt among adolescents. Data for this study came from the 2017 Youth Risk Behavior Surveillance System. A sample of 14,547 adolescents aged 14-18 years old (50.5% female) was analyzed using logistic regression. Of the 14,547 adolescents, 4% carried a weapon on school property, and 7.7% attempted suicide during the past 12 months. In the multivariate logistic regression, adolescents who reported carrying a weapon on school property had more than double the odds of attempting suicide when compared to their counterparts who did not carry a weapon on school property. Other significant predictors of suicide attempt include sexual minority, history of forced sexual intercourse, school bullying and cyberbullying victimization, feeling sad or hopeless, and substance use. Examining the association between weapon carrying and suicide attempt among adolescents would contribute to early identification of adolescents who are likely to engage in suicidal behaviors.

Inter-relatedness of underlying factors for injury and violence among adolescents in rural coastal Kenya: A qualitative study

We utilized a socio-ecological model to explore views from 85 young people and 10 local stakeholders on forms and underlying factors for unintentional injury, violence, self-harm, and suicidal behavior of adolescents in Kilifi County, Kenya. Young people took part in 11 focus group discussions, whereas 10 in-depth interviews were conducted with the local stakeholders. Road traffic accidents, falls, fights, sexual and gender-based violence, theft, and vandalism were viewed as common. There was an overlap of risk factors, especially at intra- and interpersonal levels (gender, poverty, substance use, parenting behavior, school drop-out). Some broader-level risk factors were insecure neighborhoods and risky sources of livelihood. Research is needed to quantify burden and to pilot feasible injury prevention interventions in this setting.

Trends and Correlates of Youth Violence-Prevention Program Participation, 2002-2016

INTRODUCTION

Adolescent participation in violence-prevention programming is critical in addressing the nation's elevated rates of youth fighting and violence. However, little is known about the secular trends and correlates of violence-prevention program participation in the U.S. Using national data, the authors examined the year-by-year trends and correlates of participation among American adolescents over a 15-year span.

METHODS

National trend data (2002-2016) were analyzed on non-Hispanic black/African American (n=35,216), Hispanic (n=45,780), and non-Hispanic white (n=153,087) youth aged 12-17years from the National Survey on Drug Use and Health in 2018. Consistent with the Centers for Disease Control and Prevention's trend analysis guidelines, the authors conducted logistic regression analyses with survey year specified as an independent variable and youth violence-prevention program participation specified as the dependent variable, while controlling for sociodemographic factors and other key correlates.

RESULTS

Youth participation in violence-prevention programs decreased significantly from 16.7% in 2002 to 11.7% in 2016, a 29% relative decrease in participation. A significant declining trend in participation over time was found across all sociodemographic subgroups examined and among youth reporting the use of violence and no use of violence in the past year. Participation among black/African American youth was significantly greater than Hispanic youth who, in turn, had significantlyhigher participation rates than white youth.

CONCLUSIONS

Youth participation in violence-prevention programming has decreased in recent years, with particularly large declines observed among younger adolescents (aged 12-14 years), youth in higher-income households, and youth reporting no past-year use of violence.

Gender Inequality and Sex Differences in Physical Fighting, Physical Activity, and Injury Among Adolescents Across 36 Countries

PURPOSE

Sex differences in adolescent health are widely documented, but social explanations for these sex differences are scarce. This study examines whether societal gender inequality (i.e., men's and women's unequal share in political participation, decision-making power, economic participation, and command over resources) relates to sex differences in adolescent physical fighting, physical activity, and injuries.

METHODS

National-level data on gender inequality (i.e., the United Nations Development Program's Gender Inequality Index) were linked to health data from 71,255 15-year-olds from 36 countries in the 2009-2010 Health Behaviour in School-Aged Children study. Using multilevel logistic regression analyses, we tested the association between gender inequality and sex differences in health while controlling for country wealth (gross domestic product per capita).

RESULTS

In all countries, boys reported more physical fighting, physical activity, and injuries than girls, but the magnitude of these sex differences varied greatly between countries. Societal gender inequality positively related to sex differences in all three outcomes. In more gender unequal countries, boys reported higher levels of fighting and physical activity compared with boys in more gender equal countries. In girls, scores were consistently low for these outcomes; however, injury was more common in countries with less gender inequality.

CONCLUSIONS

Societal gender inequality appears to relate to sex differences in some adolescent health behaviors and may contribute to the establishment of sex differences in morbidity and mortality. To reduce inequalities in the health of future generations, public health policy should target social and cultural factors that shape perceived gender norms in young people.

Identifying protective factors that potentially buffer the association between peer victimization and weapon-carrying behavior among US adolescents

The aim of the present study was to explore whether protective factors, such as ease of communication with parents, siblings, and best friends; parental awareness of student’s friends and activities; higher numbers of best friends; positive perceptions of school climate; and teachers’ opinion of student’s academic performance, would buffer the link between peer victimization and weapon-carrying behavior among US adolescents. Data were derived from the 2009–2010 Health Behavior in School-Aged Children (HBSC) study in the US. A total of 12,642 US adolescents were included in the study sample. Analyses included descriptive statistics, bivariate correlations, and ordinary least squares regression. Partially supporting our hypothesis, we found that only mother’s awareness of students’ friends and activities ameliorated the effect of peer victimization on weapon-carrying behavior. In other words, bullied adolescents whose mothers were aware of their friends and activities were less likely to carry weapons. Mothers’ awareness of their child’s friends, behaviors, and activities is an important form of parental monitoring, and their involvement may protect their children from weapon-carrying behavior after experiencing victimization.

Longitudinal Heterogeneity in Handgun-Carrying Behavior Among Urban American Youth: Intervention Priorities at Different Life Stages

PURPOSE

To determine longitudinal patterns of handgun-carrying behavior among urban American youth and identify modifiable risk factors associated with distinct carrying patterns that should be targeted at different life stages.

METHODS

Using panel data from the National Longitudinal Survey of Youth 1997, we estimated longitudinal trajectories of handgun carrying among urban Americans, who carried a handgun at least once between 1997 and 2011 (N = 1,574). Multinomial logistic regression analyses examined risk factors associated with handgun-carrying trajectory groups during late adolescence (ages 16-20), emerging adulthood (ages 20-24), and young established adulthood (ages 24-28).

RESULTS

Group-based trajectory analyses identified four groups: Declining (35.0%, N = 560), bell-shaped (35.5%; N = 561), late-initiating (19.6%; N = 303), and high-persistent (9.9%; N = 150). During late adolescence, lower risks of mental health problems, hard drug use, police arrest, and presence of a gang in the neighborhood or school differentiated the late-initiating group from the other higher risk groups. During emerging and young established adulthood, higher risks of alcohol use, police arrest, and presence of a gang in the neighborhood or school were associated with trajectory groups with higher likelihood of handgun carrying than the declining group.

CONCLUSIONS

There are more than one profile of adolescents and young adults who carry handguns. Preventive interventions should have distinct priorities that address different patterns of handgun-carrying behavior at different life stages.

Adolescent Cyberbullying and Weapon Carrying: Cross-Sectional and Longitudinal Associations

This study examines the cross-sectional and longitudinal associations between weapon carrying and cyberbullying (i.e., perpetration, victimization, and perpetration/victimization) and explore the relationship directions. Four waves of data were used from an ongoing longitudinal study. Participants were 1,042 adolescents, including 55.9 percent female, 31.7 percent Hispanic, 30.3 percent white, 26.6 percent African American, and 11.4 percent other, with a mean age of 15.1 years at baseline. Logistic regressions identified cross-sectional associations between weapon carrying and cyberbullying perpetration and victimization, but not for perpetration/victimization. Compared with their noninvolved counterparts, cyberbullying perpetrator were 1.97 times more likely to carry a weapon 1 year later and cyberbullying perpetrator/victims were 2.65 times more likely to carry a weapon one year later. Youth who had carried a weapon were 1.97 times more likely to be cyberbullying victims 1 year later and 1.70 times more likely to be a victim 2 years later, compared with their nonweapon-carrying counterparts. The findings highlight the importance of intervention programs targeting both cyberbullying perpetration and weapon carriage.

Physical Fighting and Associated Factors among Adolescents Aged 13-15 Years in Six Western Pacific Countries

Youth violence is an important public health challenge around the world, yet the literature on this problem in low- and middle-income countries (LMICs) has been limited. The present study aims to examine the prevalence of adolescent physical fighting (defined as having been involved in at least one physical fight during the past 12 months) in selected LMICs, and its relations with potential risk factors. We included 6377 school-going adolescents aged 13–15 years from six Western Pacific (WP) countries that had recently conducted a Global School-based Student Health Survey. Information was gathered through a self-administered anonymous closed-ended questionnaire. The prevalence of adolescent physical fighting varied across countries, ranging from 34.5% in Kiribati to 63.3% in Samoa. The prevalence was higher in boys than in girls, and lower at age 15 than 13–14 years. Physical fighting was significantly associated (pooled odds ratios (ORs), 95% confidence intervals (CIs)) with smoking (1.78, 1.53–2.06), drinking (1.57, 1.33–1.85), drug use (1.72, 1.33–2.23), and missing school (1.72, 1.51–1.95). The association with physical fighting increased with increasing number of joint adverse behaviors (increased from 1.99 (1.73–2.29) for one risk behavior to 4.95 (4.03–6.07) for at least 3 risk behaviors, versus having none of the 4 risk behaviors). The high prevalence of physical fighting and the associations with risk behaviors emphasize the need for comprehensive prevention programs to reduce youth violence and associated risk behaviors.

Health lifestyles across the transition to adulthood: Implications for health

Research has long established the importance of individual health behaviors such as cigarette smoking for adult morbidity and mortality. However, we know little about how health behaviors cluster into health lifestyles among adolescents and young adults in the United States, or in turn, how such health lifestyles are associated with young adult health outcomes. This study establishes health lifestyles as distinct group phenomena at three developmental time points in a single cohort: late adolescence (ages 15-17), early adulthood (ages 20-24), and young adulthood (ages 26-31). We then identify the associations between these health lifestyles and young adult health outcomes. We use the National Longitudinal Study of Adolescent to Adult Health (Add Health), a nationally representative sample of U.S. adolescents followed into adulthood, and latent class analysis and regression models. We uncover diverse health lifestyles among adolescents, early adults, and young adults; however, few individuals engaged in a consistently salubrious lifestyle at any developmental stage. People with less healthy lifestyles also tended to exhibit poorer health in young adulthood. Our results showed that young adult health lifestyles were significantly associated with young adult cardiovascular risk. Moreover, health lifestyles in each of the three developmental stages were associated with young adult self-rated health, and accounting for lifestyles in later stages explained some of these associations. Overall, this study suggests a portrait of problematic health lifestyles among a nationally representative cohort of young Americans, with associated patterns of relatively poor physical health among those with poor health lifestyles.

Access to a Loaded Gun Without Adult Permission and School-Based Bullying

PURPOSE

Gun access and bullying are risk factors for sustaining or perpetrating violence among adolescents. Our knowledge of gun access among bullied students is limited.

METHODS

We used data on students, aged 12-18 years, from the 2011 and 2013 School Crime Supplement to the National Crime Victimization Survey to assess the association between self-reported bullying victimization (traditional and cyber) and access to a loaded gun without adult permission. Prevalence ratios (PRs) and confidence intervals (CIs) were obtained from multivariable Poisson regression using the Taylor series after controlling for student age, sex, family income, public/private school, and race.

RESULTS

Of 10,704 participants, 4.2% (95% CI: 3.8%-4.6%) reported gun access. Compared with nonbullied students, those who reported traditional bullying (PR = 2.2; 95% CI: 1.7-2.4), cyberbullying (PR = 2.8; 95% CI: 1.6-4.9), and both (PR = 5.9; 95% CI: 4.6-7.7) were more likely to also report gun access.

CONCLUSIONS

Adolescents who experience bullying, particularly those who report both traditional bullying and cyberbullying, are more likely to report access to a loaded gun without adult permission. These findings highlight the importance of developing interventions focused on these modifiable risk factors for preventing self-directed or interpersonal violence among youth.

Development of the SaFETy Score: A Clinical Screening Tool for Predicting Future Firearm Violence Risk

BACKGROUND

Interpersonal firearm violence among youth is a substantial public health problem, and emergency department (ED) physicians require a clinical screening tool to identify high-risk youth.

OBJECTIVE

To derive a clinically feasible risk index for firearm violence.

DESIGN

24-month prospective cohort study.

SETTING

Urban, level 1 ED.

PARTICIPANTS

Substance-using youths, aged 14 to 24 years, seeking ED care for an assault-related injury and a proportionately sampled group of non-assault-injured youth enrolled from September 2009 through December 2011.

MEASUREMENTS

Firearm violence (victimization/perpetration) and validated questionnaire items.

RESULTS

A total of 599 youths were enrolled, and presence/absence of future firearm violence during follow-up could be ascertained in 483 (52.2% were positive). The sample was randomly split into training (75%) and post-score-construction validation (25%) sets. Using elastic-net penalized logistic regression, 118 baseline predictors were jointly analyzed; the most predictive variables fell predominantly into 4 domains: violence victimization, community exposure, peer influences, and fighting. By selection of 1 item from each domain, the 10-point SaFETy (Serious fighting, Friend weapon carrying, community Environment, and firearm Threats) score was derived. SaFETy was associated with firearm violence in the validation set (odds ratio [OR], 1.47 [95% CI, 1.23 to 1.79]); this association remained (OR, 1.44 [CI, 1.20 to 1.76]) after adjustment for reason for ED visit. In 5 risk strata observed in the training data, firearm violence rates in the validation set were 18.2% (2 of 11), 40.0% (18 of 45), 55.8% (24 of 43), 81.3% (13 of 16), and 100.0% (6 of 6), respectively.

LIMITATIONS

The study was conducted in a single ED and involved substance-using youths. SaFETy was not externally validated.

CONCLUSION

The SaFETy score is a 4-item score based on clinically feasible questionnaire items and is associated with firearm violence. Although broader validation is required, SaFETy shows potential to guide resource allocation for prevention of firearm violence.

Depressive Symptoms and Involvement in Physical Fighting among Portuguese Adolescents

In this article, authors present findings on the relationship between depressive symptoms and involvement in physical fighting in late adolescence. Participants were 1,380 Portuguese adolescents initially recruited in 2003 to the EPITeen cohort. Depressive symptoms were assessed at 13 and 17 years of age using Beck Depressive Inventory II (BDI). Physical fighting was recorded at the age of 17. For girls, there was a significant association between depressive symptoms and physical fighting for those who scored BDI >13 at 17 years old and remained statistically significant after adjustment. For boys, those who scored >13 in both study waves presented higher crude odds to engage in fights that were attenuated after adjusting for grade retention. Depressive symptoms were significantly related to physical fighting involvement during adolescence, for both genders. However, whereas for female adolescents the association was significant when relevant symptoms and fighting occurred in the same period, for male adolescents such symptoms must have persisted from 13 to 17 years of age.

Armed Kids, Armed Adults? Weapon Carrying From Adolescence to Adulthood

While much existing research has examined either juvenile or adult weapon carrying, this study assesses whether carrying a weapon to school as a juvenile is predictive of bringing a handgun to school or work in adulthood. Data are drawn from the National Longitudinal Study of Adolescent Health. Results show a decline in weapon carrying behavior over time. However, youth who report school weapon carrying in adolescence are much more likely to report carrying a handgun to school or work in adulthood. Findings also demonstrate that victimization, rather than offending behavior, is predictive of adulthood handgun carrying at school and work.

Handgun carrying among White youth increasing in the United States: New evidence from the National Survey on Drug Use and Health 2002-2013

The objective of the present study was to examine trends and correlates of handgun carrying among adolescents ages 12-17 in the United States. Data was derived from the National Survey on Drug Use and Health (NSDUH) involving non-Hispanic White, African American, and Hispanic respondents ages 12-17 (n=197,313) and spanning the years 2002-2013. Logistic regression was used to examine significance of trend year and correlates of previous 12-month handgun carrying. The overall self-reported prevalence of handgun carrying was 3.4%. The prevalence of handgun carrying during 2004-2005 was significantly higher for African-Americans (4.39%) compared to non-Hispanic Whites (3.03%). However, by 2012-2013, non-Hispanic Whites (4.08%) completely diverged and reported carrying handguns significantly more than both African-American (2.96%) and Hispanic (2.82%) youth. Male gender and a number of externalizing behaviors were significant correlates of handgun carrying; however, we also found evidence of differential correlates with regard to such factors as drug selling, parental affirmation, and income by race/ethnicity. To our knowledge, this is the largest study of handgun carrying among youth in the United States. Findings indicate that although at historically low levels handgun carrying is on the rise but only among non-Hispanic Whites. Differential correlates among racial/ethnic groups suggest prevention programming and policies may need modifications depending on group and geographic locale targeted.
