Abstract

Objectives:

The purpose of the study was to investigate the prevalence and associated factors of being in a physical fight in “association of Southeast Asian nations” (ASEAN) member states.

Methods:

The total sample consisted of 30284 adolescents aged 13 - 15 years from seven ASEAN countries that were included in the cross-sectional “global school-based student health survey” (GSHS) between 2007 and 2013.

Results:

The prevalence of “being in a physical fight in the past 12 months” across seven ASEAN countries (excluding Brunei) was 30.1%, ranging from below 15% in Cambodia and Myanmar to more than 30% in Indonesia, Malaysia, Philippines and Thailand. In multivariate logistic regression analysis, sociodemographic factors (younger age, being male, the experience of hunger) and risk behavior (sedentary behavior, ever had sex, tobacco use, alcohol use, truancy, being bullied, and having sustained an injury) were found to be associated with “having been in a physical fight” in the past year. Lack of protective social-familial factors (low peer support and low parental or guardian support) were only associated with physical fighting in bivariate analyses.

Conclusions:

A significant proportion of physical fighting was found in ASEAN calling for interventions aimed to prevent physical fighting considering identified associated factors.

1. Background

Youth violence (bullying, slapping, hitting or assault) is a significant public health problem and may start early and continue into adulthood (1). Experiencing violence during childhood may contribute to health risk behaviors, psycho-social problems and academic problems (2, 3). Globally, one in three adolescents had been “in a physical fight in the past 12 months” (4) and 10.7% of male in 2.7% of female school adolescents were involved in frequent (4 or more times) physical fighting in the past 12 months (2). Across 28 countries, the highest mean prevalence of any “physical fighting in the past 12 months” was found among adolescents in the Eastern Mediterranean region (46.7%), and the lowest in the USA (31.4%) (5). In the Asian region, 27.4% of school children reported “having been in a physical fight in the past 12 months” in Malaysia (6) and in the Philippines 50.0% (7). There is a lack of contextual data on youth violence (physical fighting) in the “association of Southeast Asian nations” (ASEAN) member states.

Factors associated with physical fighting in adolescents can be grouped into sociodemographic factors, risk behaviors, including psychological distress, and lack of protective social-familial factors (8). Sociodemographic factors may include, male gender (3, 9, 10), decreased with age (3, 11), low economic status (3, 12), living in lower income countries (2). Risk behaviors may include alcohol use (6, 9, 13, 14), smoking (6, 9, 10, 14-16), bullying victimization (3, 6, 10, 15, 17, 18), being sexually active (16), sedentary behavior (14, 17), and psychological distress (12, 15-17). Lack of social-familial protective factors may include lack of peer support (13), and lack of parental support (9, 10, 12, 13, 19).

The purpose of the study was to investigate the prevalence and associated factors of being in a physical fight in “association of Southeast Asian nations” (ASEAN) member states.

2. Methods

2.1. Sample and Procedure

This investigation utilized existing and publicly available data from the “global school-based student health survey” (GSHS) from seven ASEAN countries (20). A “two-stage cluster sample design” with selecting schools and then classes were used to gather data representative of all students in grades 6 to 10 in each country” (20). The participating students were asked to complete a questionnaire under the direction of trained research assistants (20).

2.2. Measures

The study instruments used in this study were from the GSHS (20) (see Table 1). “Sedentary behavior was defined as spending 3 or more hours per day sitting when not in school or doing homework.” (21). “Physical inactivity was defined as obtaining less than 60 minutes of moderate to vigorous-intensity physical activity per day on at least 5 days per week.” (21).

Based on self-reported body weight and height, the “international age- and gender-specific child body mass index (BMI)” was used to classify children as overweight and obese (22). Psychological distress was assessed with three items (no close friends, feeling often or always lonely, and suicidal ideation), and parental or guardian support was also measured with three items (often or always supervision, connectedness and bonding) (see Table 1).

2.3. Data Analysis

Using STATA software version 13.0 “(Stata Corporation, College Station, Texas, USA)” data were analysed taking into account for the sampling design. In the analysis each country sample was restricted to the 13 to 15 years age range, so as to compare study samples across countries. Associations between socio-demographics, risk behavior, social-familial protective factors and past 12 months physical fighting among school adolescents were analyzed calculating odds ratios (OR). Logistic regression estimated the impact of independent variables on having experienced physical fighting in the past 12 months (dependent variable), with the inclusion of significant bivariate analysis variables in the final multivariate model. The proportions, P value and the reported 95% confidence intervals were adjusted for the multistage stratified cluster study design.

3. Results

3.1. Sample Characteristics

The overall sample included 30284 school-going children (aged 13 - 15 years) from seven ASEAN member states. The sample size in the participating individual countries ranged from as low as 1734 in Cambodia to as high as 16066 in Malaysia, 48.5 were male students and 51.5% were female students, and the overall mean age was 14.0 years (SD = 0.8). The year of data collection ranged from 2007 in Indonesia and Myanmar to 2013 in Cambodia and Vietnam, and the overall response rate ranged from 82% in the Philippines to 96% in Vietnam. Overall, 30.1% of the students reported “being in a physical fight in the past year”, 40.0% among boys and 20.7% among girls. There were country variations in the prevalence of physical fighting, ranging from below 15% in Cambodia and Myanmar to more than 30% in Indonesia, Malaysia, Philippines and Thailand. Among boys, the prevalence of being in a physical fight was higher in students residing in an upper middle income country (Malaysia, Thailand) than in a low or lower middle country (Cambodia, Indonesia, Myanmar, Philippines and Vietnam) (23) (see Table 2).

3.2. Associations with Being in a Physical Fight

In multivariate logistic regression analysis, sociodemographic factors (younger age), being male, the experience of hunger) and risk behavior (leisure time sitting of 3 or more hours a day, ever had sex, current tobacco use, current alcohol use, truancy in the past month, being bullied in the past month, and “having sustained an injury in the past year”) were found to be associated with “having been in a physical fight in the past year”. Lack of protective social-familial factors (low peer support and low parental or guardian support) were only associated with physical fighting in bivariate analyses (see Table 3).

4. Discussion

The study investigated in a large sample of school-going adolescents across seven ASEAN countries the prevalence and correlates of physical fighting. The prevalence of past 12 months physical fighting in this study was lower than in previous studies (5) in different world regions, except for USA, which had a similar prevalence. However, the study found a considerable country differences in the prevalence of physical fighting experiences, ranging from below 15% in Cambodia and Myanmar to more than 30% in Indonesia, Malaysia, Philippines and Thailand. Some previous studies seem to confirm a problem of different forms of youth violence in Indonesia (25), Malaysia (15), Philippines (7, 26) and Thailand (27-29). It is, however, not clear why such large country differences were found, some authors (e.g., 5), propose that “cultural norms and practices” may affect the proportion of physical fighting among young people. The proportion of physical fighting among adolescents in the ASEAN region, in particular in Indonesia, Malaysia, Philippines and Thailand, is a concern and calls for intervention programmes.

In agreement with previous studies (3, 9-12), this study found a higher prevalence of physical fighting among boys than girls, younger than older students and school children with a poorer (experiencing hunger as a proxy of socioeconomic status) than richer family background. The finding that physical fighting was more frequent among boys than girls in all countries except for Cambodia was not unexpected, traditional masculine gender socialization may contribute to this (6, 9). The declines of physical fighting with age “may be due to young people developing the cognitive, emotional, behavioral and verbal resources to cope with frustrations and conflicts in a more constructive and less physical manner as they grow older.” (30). Lower economic status may result in social conditions promoting acceptance in society (3) and biological effects of hunger may increase emotional stress and violence (3). Contrary to a previous review in school children from 79 countries (2) that found a higher prevalence of physical fighting in students living in lower income countries, this study found, among boys that physical fighting was higher in the upper middle income compared to lower income countries. It is possible that in upper middle income countries income inequality was higher than in low or lower middle income countries, contributing, thus, to higher rates of physical fighting among boys.

In previous studies (6, 9, 10, 12-18), various risk behaviors were found to be associated with being in a physical fight, which were also found in this study, including alcohol use, smoking, bullying victimization, truancy, being sexually active and sedentary behavior. In bivariate analysis, psychological distress was also found to increase the odds for physical fighting, as found in previous studies (12, 15-17). Various researchers (6, 8-10) indicated that we may have here a clustering of unhealthy behaviors, which could mean that interventions should also address multiple risk behaviors in adolescents.

Regarding social-familial protective factors, this study found in bivariate analysis that lack of peer and parental support was correlated with physical fighting, which was found in several studies conducted previously (9, 10, 12, 13, 19). This finding could possibly mean that the promotion of a social-familial supportive atmosphere could aid in the reduction of physical fighting in school children.

Study limitations include the cross-sectional study design and that the study includes only school going adolescents. The prevalence of physical fighting may differ between school-going and non-school going adolescents. Moreover, data were collected by self-report, which may have biased the results.

4.1. Conclusion

The study found in a large sample of adolescents across seven ASEAN member states a significant proportion of physical fighting behavior. Several sociodemographic and a number of clustering risk factors were identified, which can help guide interventions to prevent physical fighting in this population.
