The prevalence of very frequent physical fighting among boys and girls in 27 countries and cities: regional and gender differences

Prevalence and correlates of physical fighting among adolescents in Paraguay: Findings from the 2017 national school-based health survey

BACKGROUND

Interpersonal violence among adolescents is a serious public health issue across the globe and has been one of the leading causes of death among Paraguayan adolescents. This study aims to investigate the prevalence of physical fighting among adolescents in Paraguay in order to identify problematic fighting behaviour. We also aim to examine the correlates of physical fighting and the extent to which previously identified factors correlate with physical fighting.

METHODS

We used the Paraguay 2017 Global School-based Student Health Survey (GSHS). This survey collects health-related information on school-attending adolescents aged 13-17 years. We defined physical fighting as having participated in at least two physical fights in the previous 12 months. We chose 16 independent variables: 12 individual-level variables and four social-level variables. Multivariable logistic regression models were developed to identify factors associated with physical fighting. One of the limitations of this study is that it only captured the responses of the students who attended school on the day of the survey.

FINDINGS

A total of 3,149 students completed the survey questionnaire, with the response rates for the school, student, and total response being 100%, 87%, and 87%, respectively. In 2017, 8% of the survey participants (11.4% of the males, and 4.7% of the females) had been involved in two or more physical fights during the past 12 months. In the multivariable model, having been physically attacked, male gender, physical activity, alcohol use, early sexual debut, and suicide planning were significantly associated with involvement in physical fighting. Having helpful peers and supportive parents was not statistically significant in the model adjusted for all variables.

CONCLUSIONS

Although Paraguay shows relatively lower prevalence of physical fighting than other countries, the high association between physical fighting and having been physically attacked is noteworthy. Considering the serious interpersonal violence among Paraguayan adolescents, preventive attributes should be considered, and further assessment of other types of interpersonal violence should be made.

The Association Between Bullying Victimization and Fighting in School Among US High School Students

In-school fighting often results in severe punishment and compromised learning outcomes, without adequate consideration of contextual factors or student vulnerabilities. In this study, using a large, nationally representative data sample from the 2019 Youth Risk Behavior Survey (N = 13677), we assessed associations between a history of bullying victimization (at school and online) and past year fighting at school among U.S. high school students. Multiple regression models were used, adjusting first for demographics, and then for demographics and emotional-behavioral risks (depressive symptoms, alcohol consumption, and sexual violence victimization), for the total sample and then stratified by gender/sex. Both cyberbullying and in-school bullying were significantly associated with past year in-school fighting for the total sample, with associations retained, but marginally attenuated in fully adjusted models (cyberbullying: AOR: 1.30; 95% CI: 1.01-1.66 and in-school bullying: AOR: 1.96, 95% CI: 1.57-2.45). Gender/sex-stratified models demonstrated retained associations for males (cyberbullying: AOR: 1.93; 1.51-2.46 and in-school bullying: AOR: 2.70, 95% CI: 2.18-3.34) and females (cyberbullying: AOR: 1.89; 1.33-2.68 and in-school bullying: AOR: 1.66, 95% CI: 1.19-2.33) after adjusting for demographics, but only for males after adjusting for demographics and emotional-behavior risk factors (cyberbullying: AOR: 1.43; 95% CI: 1.07-1.93 and in-school bullying: AOR: 2.25; 95% CI: 1.73-2.92). These results demonstrate a significant association between bullying victimization and fighting, which was amplified for male students, and partially explained by social and emotional risks. This suggests that punitive approaches to fighting in school may be resulting in compounded harms for already vulnerable adolescents and that support-oriented approaches emphasizing conflict resolution, social-emotional well-being, positive gender identity development, and bullying prevention may be more appropriate.

A health promotion intervention to address youth violence among students in a technical college in Sri Lanka guided by the participatory action research approach: a study protocol

BACKGROUND

Youth violence is a global public health issue and the highest rates are reported in Low and Middle-Income Countries (LMICs). Higher rates of youth violence are reported in Sri Lanka as well. Students who fail to continue higher studies in schools or enter the universities in Sri Lanka, enroll in technical colleges and are associated with a higher number of risk factors of violence. This study aims to empower youth (15-29 years old) of a technical college in Matale district, Sri Lanka, to carry out activities among themselves to improve their knowledge, change perceptions, and violence-related behaviours.

METHODS

The Participatory Action Research (PAR) approach will be used. The study participants will be eighty students in a technical college in Matale district, Sri Lanka. The study period will be three years. Study participants will also be collaborators and they will involve actively in all stages of the study. A health promotion intervention will be implemented to identify determinants of youth violence and to design and implement actions while monitoring the changes. The data will be collected mainly through focus group discussions and key informant interviews both before and after the health promotion intervention. Additionally, a self-administered questionnaire will be used and the principal investigator will maintain a reflective diary. The qualitative data will be analysed thematically whereas quantitative data will be analysed using descriptive statistics. Data will be triangulated to increase the rigour of the study.

DISCUSSION

According to literature, PAR is not widely used in health promotion. The enabling and empowerment goals of health promotion are fulfilled in PAR. Thus, this will be a novel experience for researchers and this will stimulate discussion on the combination of PAR and health promotion. This study design itself promotes active participant involvement and it may generate effective youth-led, culturally appropriate actions to address youth violence. The findings will describe what works and why it works and will help Sri Lanka and similar LMICs to create safe environments for youth in educational institutes or training colleges.

The Association between Participation in Fights and Bullying and the Perception of School, Teachers, and Peers among School-Age Children in Serbia

Participating in physical fighting and bullying can be a cause of severe injury and death among school-age children. Research evidence can support school and health actors' efforts to improve school-age children's development and health capacity for life. The study aims to assess the prevalence of school-age children's participation in fights and bullying in Serbia, and to examine the relevance of students' socio-demographic characteristics and perceptions of school and relations with other students and professors for participation in fights and bullying. A secondary analysis is also performed on the original data of the 2017 HBSC study, which was conducted on 3267 students in a nationally representative sample of primary and high schools in Serbia. We sought to investigate the relationship between eight socio-demographic characteristics and nine school-related perceptions, with two outcome variables: taking part in fights and taking part in bullying, examined by using univariate and multivariate logistic regression. The main results show that 50.8% of boys and 17.1% of girls have taken part in fights, while 17.7% boys and 10.4% of girls have taken part in bullying. Students who felt a large and very large burden of school obligations were 1.43 times more likely to participate in bullying at least once, while they were 1.38 and 2.12 times more likely to participate in multiple fights and 4.04, 1.24, and 2.78 times more likely to participate multiple times in bullying. Multiple participation in fights and in bullying is significantly negatively associated with female gender, younger age years, good and very good perception of family financial status and quality of life, and positive perceptions of school and relations they have with other students and professors. Fights among school-age children are significantly positively associated with living with relatives/legal guardians and poor quality of life. In conclusion, the prevalence of participating in at least one fight/bullying is higher than in multiple fights/bullying. These associations suggest a necessity to enhance the monitoring and control of peer behavior among school-age children. The findings of the study imply key enablers of protection, such as building relationships based on team spirit and work, friendly behavior, empathy, and help, which should be included in the value system of school and family activities in programs to combat fights and bullying in school-age children.

Interpersonal violence among in-school adolescents in sub-Saharan Africa: Assessing the prevalence and predictors from the Global School-based health survey

Interpersonal violence in adolescents has over the years grown into a serious public health problem that merits a robust intervention. This study, therefore, assessed the prevalence and predictors of interpersonal violence among in-school adolescents in sub-Saharan Africa (SSA). The study involved a cross-sectional analysis of data from the Global School-based Health Survey conducted between 2012 and 2017 from eight sub-Saharan African countries. A total of 14,967 in-school adolescents aged 10-19 years were included in the pooled analysis. A multivariable binomial logistic regression was used to determine the predictors of interpersonal violence using the adjusted odds ratio (aOR) with their respective 95% confidence intervals (CIs). The overall prevalence of interpersonal violence among in-school adolescents in SSA was 53.7%. The odds of interpersonal violence were higher among adolescents who were bullied (aOR = 2.52, 95% CI = 2.23-2.85), had an injury (aOR = 2.42, 95% CI = 2.15-2.72), had suicidal attempts (aOR = 1.40, 95% CI = 1.16-1.70), were truant (aOR = 1.51, 95% CI = 1.33-1.72), used alcohol (aOR = 1.49, 95% CI = 1.06-2.11), and used tobacco (aOR = 1.46, 95% CI = 1.23-1.74). In-school adolescents with peer support, parents or guardians bonding, those whose parents or guardians respected their privacy, and those aged 15 years or older were less likely to experience interpersonal violence. These factors provide education directors and school heads/teachers with relevant information to guide the design of specific interventions such as parent-teacher meetings and programs, peer educator network system, face-to-face counseling sessions, Rational Emotive Behavioural Education (REBE) and substance use cessation therapy to prevent interpersonal violence, particularly physical fights and attacks in school settings. Also, students should be sensitized on the negative effects of interpersonal violence and those who have been exposed to it should be counselled. School rules should be strengthened and appropriate punishment given to students who engage in violence baheviours in schools in order to deter others from engaging in them.

Physical fighting among adolescents in eastern Ethiopia: a cross-sectional study

Background

Physical fights have been a common health problem among adolescents, and approximately a million adolescents’ lives are lost due to violence-related incidents worldwide. There is a lack of information on the burden of adolescents’ physical fights in eastern Ethiopia. Hence, the study aims to estimate the magnitude and assess factors associated with physical attacks and fighting among adolescents in eastern Ethiopia.

Methods

A community-based cross-sectional study was conducted among 2424 adolescents in eastern Ethiopia in 2016. Simple random sampling was used to recruit study participants. Data were collected by trained interviewers using a structured questionnaire developed by the Africa Research, Implementation Science and Education (ARISE) network and adapted from the World Health Organization Global school-based student health survey. Descriptive statistics, binary and multivariable logistic regression were performed. Statistical associations were determined using adjusted odds ratio (AOR) at 95% Confidence Intervals (95% CIs) and P-value < 0.05.

Results

Prevalence of physical attacks and physical fights was 5.8%, and 26.4%, respectively. Adolescents who attended school (AOR 0.4, 95% CI: 0.2–0.9) and who chewed Khat (AOR 0.4, 95% CI: 0.2–0.8) were less likely to experience physical attacks. Male adolescents were two times more likely to engage in physical fights than female adolescents (AOR 2.4, 95% CI: 1.8–3.2). In-school adolescents who attended secondary (AOR 0.4, 95% CI: 0.2–0.7) or tertiary level of education (AOR 0.2, 95% CI: 0.1–0.7) were less likely to participate in physical fighting than those with primary level education. Adolescents who had ever engaged in physical work to earn money for food or drink were 1.9 times more likely to be physically attacked compared to those who had not (AOR 1.9, 95% CI: 1.0–3.5).

Conclusion

Physical attacks and fights were found to be common experiences of adolescents in eastern Ethiopia. Future research and programs should emphasize preventive health programs for reducing violence and promoting school enrolment and retention.

Prevalence and nature of bullying in schools of Bangladesh: A pilot study

Bullying at schools is considered as the most contemptible anti-social behavior for students (Neto, 2005). There is little information about the prevalence and nature of bullying victimization experiences among Bangladeshi school students. Therefore, the present study aimed to investigate the prevalence and nature of bullying experienced by Bangladeshi school students. A sample of 556 students were surveyed utilizing the translated Bangla version of the Multidimensional Bullying Victimization Scale. Nearly half of the participants were bullying victims in schools over the last year. Results showed that the most commonly experienced forms of bullying were pushing or shoving, being made fun of, and having rumours spread. Students who were boys, from public schools, and lived in urban areas had significantly higher bullying victimization experiences. Findings of this present study would be helpful for the policymakers and other stakeholders to reform anti-bullying policies and appoint school psychologists to ascertain positive behavior and eliminate bullying entirely.

Sex differences in early experience and the development of aggression in wild chimpanzees

Sex differences in physical aggression occur across human cultures and are thought to be influenced by active sex role reinforcement. However, sex differences in aggression also exist in our close evolutionary relatives, chimpanzees, who do not engage in active teaching, but do exhibit long juvenile periods and complex social systems that allow differential experience to shape behavior. Here we ask whether early life exposure to aggression is sexually dimorphic in wild chimpanzees and, if so, whether other aspects of early sociality contribute to this difference. Using 13 y of all-occurrence aggression data collected from the Kanyawara community of chimpanzees (2005 to 2017), we determined that young male chimpanzees were victims of aggression more often than females by between 4 and 5 (i.e., early in juvenility). Combining long-term aggression data with data from a targeted study of social development (2015 to 2017), we found that two potential risk factors for aggression-time spent near adult males and time spent away from mothers-did not differ between young males and females. Instead, the major risk factor for receiving aggression was the amount of aggression that young chimpanzees displayed, which was higher for males than females throughout the juvenile period. In multivariate models, sex did not mediate this relationship, suggesting that other chimpanzees did not target young males specifically, but instead responded to individual behavior that differed by sex. Thus, social experience differed by sex even in the absence of explicit gender socialization, but experiential differences were shaped by early-emerging sex differences in behavior.

Gender differences and the correlates of violent behaviors among high school students in a post-conflict area in Indonesia

INTRODUCTION

Adolescent violence is a public health problem worldwide. Studies show that challenging environments, such as poverty and war, increase the risk of adolescent violence. This paper aims to assess gender differences in violent behaviors among adolescents in a post-conflict area in Indonesia. The other aim of this study is to investigate the correlates of adolescents' violent behaviors using the socio-ecological framework.

METHODS

This is a school-based study involving 511 students from six randomly selected high schools in Kotamadya Ambon. Active and verbal violent behaviors and the potential correlates were measured and assessed using backward linear regression analyses.

RESULTS

Boys were involved in more violent behaviors than girls. However, some of the boys and girls reported being involved in all types of violent behaviors. The most significant correlates of violent behaviors across genders were community violence exposure and some types of behavioral problems.

DISCUSSION

This study highlighted the interconnectedness between community violence exposure and violent behaviors among adolescents living in a post-conflict area. The study also emphasizes the association between problem behaviors and violent behaviors. The results demonstrate the importance of both reducing community violence exposure and identifying adolescents with behavioral problems in the prevention of violent behaviors.

Aggressive Behaviors among 15-16-Year-Old Romanian High School Students: Results from Two Consecutive Surveys Related to Alcohol and Other Drug Use at the European Level

The aim of this paper is to examine aggressive behaviors among Romanian high school students between 15 and 16 years old, to compare data in two national representative samples and to identify factors associated with physical fighting. This study investigates the association of selected factors (social, school performance and substance use) with physical fighting. A total of 2289 Romanian students were included in the 2007 database and 2770 in the 2011 database. This study revealed that 35.87% of the teenagers have taken part in a physical fight during the previous 12 months, as compared with the European average of 31.5%. Romania has the highest prevalence of violent behavior by participating in a group bruising of an individual in both surveys, 2007 and 2011. A logistic regression analysis performed for the 2011 study revealed the following factors associated with physical fighting: binge drinking during the previous 30 days, male gender, serious problems with friends, parent(s) who do not know where and with whom the adolescents spend their evenings, poor parental caring, low school grades, and high truancy. A decrease in almost all aggressive behaviors was noticed in 2011, compared to 2007. These findings may be useful to support and guide policy makers regarding improvement and implementation of strategies to further prevent aggressive behaviors in teenagers.

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.

Involvement in Physical Fights among School Attending Adolescents: A Nationally Representative Sample from Kuwait

Background: Interpersonal violence in school settings is an important public health problem worldwide. This study investigated the individual and social correlates for being involved in a physical fight amongst a nationally representative sample of school-attending adolescents in Kuwait. Methods: We carried out bivariate and multivariate analyses to determine the strength and direction of associations with adolescent involvement in problematic fighting behavior within a 12-month recall period. Results: Within a total sample of 3637, n = 877 (25.2%) of school-attending adolescents reported being involved in two or more physical fights during the recall period. The multivariate analysis indicated that being male (OR = 2.71; CI = 1.88–3.90), a victim of bullying (OR = 2.77; CI = 2.14–3.58), truancy (OR = 2.52; CI = 1.91–3.32), planning a suicide (OR = 2.04; CI = 1.49–2.78) and food deprivation (OR = 1.91; CI = 1.37–2.65) were associated with an increased risk of involvement in physical fighting. Peer support in the form of having close friends (OR = 0.85; CI = 0.76–0.96) was found to be associated with a reduced involvement in fighting behavior. Conclusion: The results, when taken together, suggest that supportive school environments may represent important settings for violence mitigation and prevention strategies.

Physical Fighting among School-Attending Adolescents in Pakistan: Associated Factors and Contextual Influences

BACKGROUND

Adolescent physical fighting is a problem of public health importance, with varied consequences in the form of school absenteeism, injury, and, in some cases, death. Although research on risk and protective factors exists, most has been conducted in high-income countries.

METHODS

The 2009 Pakistan Global School-based Health Survey (GSHS) data were used. Logistic regression models were used to determine the associations. Five independent variables were investigated at the individual level (anxiety, suicide planning, truancy, physical activity, and bullying victimization) and four independent variables at the social level (presence of supportive parental figures, presence of helpful peers, extent of social network, and food insecurity).

RESULTS

Among adolescents in this study (N = 5177), 20% reported being involved in two or more physical fights, most of whom were males (79.9%). The factors associated with physical fighting were: being male (OR = 2.78); bullying victimization (OR = 3.14); truancy (OR = 1.63), loneliness (OR = 1.44); and suicidality, as evidenced by having a suicide plan (OR = 1.75). Having few close friends (0-2) as opposed to more (>3) was found to be protective against engaging in physical fighting.

CONCLUSION

Risk factors for physical fighting among adolescents in South Asia seem to corroborate with previously-identified risk factors using samples in high-income countries, while protective factors seemed to differ. More research needs to be conducted to understand why certain factors do not have the same protective effect among South Asian adolescents.

AIM

The aim of this study was to examine demographic and contextual factors associated with physical fighting among a nationally representative sample in a rapidly developing South Asian context.

Relationship between bullying and type 1 diabetes mellitus in children and adolescents: a systematic review

OBJECTIVE

To carry out a systematic review on the relationship of bullying with type 1 diabetes in children and adolescents.

METHODS

Systematic review, according to the PRISMA methodology, in which the databases PubMed, Web of Science, Scopus, Thomson Reuters, Eighteenth Century Collections Online, Begell House Digital Library, LILACS, and SciELO were searched using the terms "bullied", "aggression", "peer victimization", "victimization", "school violence", "diabetes mellitus", "type 1 diabetes mellitus", "autoimmune diabetes", "children" and "adolescents." The authors included original studies, involving bullying associated with type 1 diabetes, with children and adolescents, without language restriction and publication period, with texts available in full.

RESULTS

Of the 32 articles found, four studies met the selection criteria. Of these studies 85.7% identified occurrence of victimization in diabetics or found a higher frequency in diabetic children and adolescents when compared with young people with other chronic conditions or with healthy peers. Association between bullying and worse glycemic control was observed in two studies, and all the studies mention the fact that type 1 diabetes is a limiting factor for socialization related to diabetes, with less social support and difficulties for the management of the disease in public environments, such as school. The type of bullying suffered varied, including physical, verbal, social, psychological, and sexual.

CONCLUSION

Most of the studies showed an association between bullying and type 1 diabetes when compared to individuals with no such condition. Knowledge of this association has become essential for the follow-up of these patients and the implementation of preventive programs.

Prevalence and Correlates of Interpersonal Violence Among In-School Adolescents in Sri Lanka: Results From the 2016 Sri Lankan Global School-Based Health Survey

Interpersonal violence among adolescents is an issue of global public health concern, leading to adverse physical and psychological outcomes among children and young people under the age of 18 years. This article discusses the prevalence of interpersonal violence and identifies their associated factors among school-going adolescents of ages 13 to 17 years using the data from the Sri Lankan Global School-Based Health Survey conducted in 2016. Of the 3262 students who participated, 35.1% (95% confidence interval = 31.0% to 39.5%) were physically attacked and 44.2% (95% confidence interval = 39.2% to 49.4%) were in a fight with peers, one or more times during the 12 months prior to the survey. Being bullied by peers, male sex, 13 to 15 years age group, smoking and alcohol use, considering or attempting suicide, missing classes without permission, and parents not being aware of students' activities were associated with violence. The study highlights the need for violence prevention programs to address the risk factors among school-going adolescents.

Prevalence of Key Forms of Violence Against Adolescents in the Arab Region: A Systematic Review

PURPOSE

This article presents a systematic review of the prevalence of violence against adolescents in the 22 countries of the Arab League.

METHODS

Data on physical and emotional child maltreatment, sexual abuse, bullying and fighting, violence in schools, and intimate partner violence against adolescent girls were retrieved using: (1) a systematic search for peer-reviewed journal articles using Medline and the Social Sciences Citation Index; and (2) a search for nationally-representative, population-based surveys.

RESULTS

Published evidence suggests that physical, sexual, and emotional violence against adolescents is widespread in the Arab region. In many studies, prevalence rates exceeded other regional or global estimates, including rates of violent discipline, fighting, and intimate partner violence against adolescent girls. Data on certain forms of violence (e.g. violent discipline) are available from many Arab countries; but data on other forms, e.g., sexual abuse, are scarce. Most peer-reviewed journal articles are based on small studies with diverse operational definitions and methods, making comparisons challenging.

CONCLUSIONS

High rates of violence against adolescents in the region merit greater attention from policy makers concerned with determinants of adolescent health. There is also a need to expand and improve the quality of quantitative and qualitative research on violence against adolescents in the region.

Youth Violence and Related Risk Factors: A Cross-sectional Study in 2800 Adolescents

Background:

Youth violence is an important public health challenge, and the literature on this problem in developing countries has been limited. The present study aims to determine the prevalence of violence its related risk factors in in a sample of students in Isfahan, Iran.

Materials and Methods:

In this cross-sectional study, 2800 middle and high school, aged 11–18 years in urban and rural areas selected in a multistage sampling procedure and were questioned using a self-administered questionnaire. Collected data included sociodemographic and family characteristics, students' knowledge, verbal and physical violence (as a perpetrator and/or victim), risk-taking behaviors (weapon carrying, threatening behaviors), family violent status, watching movies, and accessibility of sport facilities.

Results:

The prevalence of verbal and physical violence in studied students was 45% and 33.3%, respectively. The prevalence of verbal and physical victimization was 45.8% and 23.6%, respectively. The prevalence of physical violence was higher in middle school students than high school students (P = 0.0001) and in boys was higher than in girls (P = 0.0001). Being boy, carried a weapon out of home or in school, victimization, feel unsafe at school, and violence in the family are the significant related risk factors with students violence (P < 0.05).

Conclusion:

The prevalence of students' violence in Iranian students is similar to the most of other developing countries, although, high rate violence and related risk factors emphasize the need for comprehensive and interventional prevention programs to reduce and manage student violence and associated risk behaviors.

Violence among Adolescents in Qatar: Results from the Global School-based Student Health Survey, 2011

Background Despite being a neglected issue in adolescent health, interpersonal violence such as physical fighting constitutes a prominent cause of physical injuries in adolescents. Aim We aimed to study the prevalence of physical fighting and its associated factors among Qatar's adolescent population. Method We analyzed secondary data from Qatar's Global School-based Student Health Survey (GSHS) 2011 to determine the prevalence as well as the associated factors of being engaged in a physical fight in the last 12 months. Results It was found that almost half of the participants (49%) were involved in a physical fight; mostly males (60.5%) than females (37.6%). Being bullied, smoking, and having parental supervision were positively associated with physical fighting (OR = 3.97, 95% CI (3.68, 4.28); OR = 1.78, 95% CI (1.61, 1.97); OR = 1.14, 95% CI (1.05, 1.23), respectively). Conclusion Further behavioral research on adolescent violence will inform the development of youth-targeted violence prevention programs.

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.

Men's violence against women and men are inter-related: Recommendations for simultaneous intervention

Men are more likely than women to perpetrate nearly all types of interpersonal violence (e.g. intimate partner violence, murder, assault, rape). While public health programs target prevention efforts for each type of violence, there are rarely efforts that approach the prevention of violence holistically and attempt to tackle its common root causes. Drawing upon theories that explain the drivers of violence, we examine how gender norms, including norms and social constructions of masculinity, are at the root of most physical violence perpetration by men against women and against other men. We then argue that simply isolating each type of violence and constructing separate interventions for each type is inefficient and less effective. We call for recognition of the commonalities found across the drivers of different types of violence and make intervention recommendations with the goal of seeking more long-standing solutions to violence prevention.

Frequency of Aggressive Behaviors in a Nationally Representative Sample of Iranian Children and Adolescents: The CASPIAN-IV Study

Background:

This study aims to explore the frequency of aggressive behaviors among a nationally representative sample of Iranian children and adolescents.

Methods:

This nationwide study was performed on a multi-stage sample of 6–18 years students, living in 30 provinces in Iran. Students were asked to confidentially report the frequency of aggressive behaviors including physical fighting, bullying and being bullied in the previous 12 months, using the questionnaire of the World Health Organization Global School Health Survey.

Results:

In this cross-sectional study, 13,486 students completed the study (90.6% participation rate); they consisted of 49.2% girls and 75.6% urban residents. The mean age of participants was 12.47 years (95% confidence interval: 12.29, 12.65). In total, physical fight was more prevalent among boys than girls (48% vs. 31%, P < 0.001). Higher rates of involvement in two other behaviors namely being bullied and bulling to other classmates had a higher frequency among boys compared to girls (29% vs. 25%, P < 0.001 for being bullied) and (20% vs. 14%, P < 0.001 for bulling to others). Physical fighting was more prevalent among rural residents (40% vs. 39%, respectively, P = 0.61), while being bullied was more common among urban students (27% vs. 26%, respectively, P = 0.69).

Conclusions:

Although in this study the frequency of aggressive behaviors was lower than many other populations, still these findings emphasize on the importance of designing preventive interventions that target the students, especially in early adolescence, and to increase their awareness toward aggressive behaviors. Implications for future research and aggression prevention programming are recommended.
