Objectives: The study aimed to report the prevalence and socio-psychological correlates of non-fatal injury among school adolescents in four ASEAN countries.
Materials and methods: Cross-sectional research data from the 2015 “Global School-based Health Survey (GSHS)” included 29,480 school adolescents (mean age 14.5 years, standard deviation=1.6) that were representative of all students in secondary school.
Results: The proportion of participants with one or multiple serious past-year injuries was 36.9% (21.4% once and 15.4% multiple times). The most frequent cause of the reported injury was “I fell” (10.2%) and motor vehicle (5.8%) and the most common form of injury was “a broken bone or dislocated joint” (8.1%) and “cut, puncture or stab wound” (3.4%). In adjusted multinomial logistic regression analysis, male sex, experiencing hunger, substance use (alcohol, tobacco, cannabis, amphetamine and soft drinks), school truancy, participating in physical education classes and psychological distress were associated with one and/or multiple injuries. Parental or guardian support decreased the odds of one annual injury. Compared to students from Indonesia, students from Laos had a lower odd for injury and students from the Philippines and Thailand had higher odds for injury.
Conclusion: Several variables, such as male sex, food insecurity, substance use, truancy, physical education and psychological distress, were identified that could be targeted in injury prevention programs in this school population.

Keywords: psychosocial factors, injury, substance use, school adolescents, ASEAN

 

Introduction

“Unintentional injuries are the largest source of premature morbidity and mortality and the leading cause of death among adolescents 10–19 years of age.”1 The South-East Asian region is disproportionally affected by the world’s unintentional injury-related deaths.2 The prevalence of past 12-month serious injuries among adolescents in “Association of Southeast Asian Member States (ASEAN)” was for example, in 20.1% in 2013 Cambodia,3 45.9% in 2008 in Indonesia,4 34.9% in 2012 in Malaysia,5 27.0% in 2007 in Myanmar,4 39.1% in 2003, 54.2% in 2007 and 54.3% in 2011 in the Philippines,6 46.8% in 2008 in Thailand4 and 29.7% in 2013 in Vietnam,3 while it was 40% (median) in “47 low- and middle-income countries.”7

The two most frequent external injury causes in investigations in South-East Asian countries included “fall”35 and vehicle or transport-related injuries.35 In the “47 low- and middle-income countries” study, 9.2% had their injuries caused by motor vehicles.7

As previously reviewed,5 risk factors for unintentional injuries in adolescents may include, sociodemographic variables, such as male sex and lower economic status and socio-psychological factors such as psychological distress, alcohol and tobacco use, soft drink consumption and risk-taking behaviors. The study aimed to report on the prevalence and socio-psychological correlates of non-fatal injury among school-going adolescents in four ASEAN countries using the latest data (2015) available from the “Global School-based Health Survey (GSHS)”. Using the available sociodemographic and psychosocial study variables associated with the occurrence of injuries from the ASEAN GSHS data, findings may generate strategic information for injury prevention in the adolescent population.

Knowing the occurrence and risk factors injury in young person can help in designing intervention strategies of injury prevention.8

Methods

Sample and procedure

The purpose of the GSHS is to periodically assess the prevalence of various health behaviors in order to set priorities for school health promotion programs in low- and middle-income countries.9 This analysis utilizes 2015 ASEAN GSHS cross-sectional data; more details and the dataset can be publicly accessed.9 The conduct of the most recent GSHS in ASEAN countries, namely in 2015, was used as country inclusion criteria to select Indonesia, Laos, Philippines and Thailand for inclusion in this paper. The GSHS utilized a uniform two-stage probability sampling design (schools were selected by probability to size sampling and random selection of classrooms with students 13–15 years old) to produce a nationally representative sample of middle school students in each study country.9 All students attending a selected class were eligible to participate, regardless of their age, and completed a self-administered questionnaire in their language under the supervision of trained external survey administrators.9 The study proposal was approved by the Ministry of Education or Health, or/and a national ethics committee, and verbal or written informed consent was obtained from the participating schools, parents and students prior to survey administration.9

Measures

The study questionnaire used was from the GSHS,9 as shown in the Table S1, and included the following variables: country, age, sex, experience of hunger, current tobacco use, current alcohol use, ever cannabis use, ever amphetamine use, soft drink consumption, attendance of physical education classes, school truancy, psychological distress, peer and parental support. The psychological distress items (no close friends, loneliness, anxiety, suicidal ideation and suicide attempt) were summed, and grouped into 0=0 low, 1=1 medium and 2–5=2 high. The four items on parental or guardian support were summed, and classified into three groups, 0–1 low, 2 medium and 3–4 high support. The reliability of GSHS was in an Asian country satisfactory (“77% agreement between test and retest and average Cohen’s kappa 0.47”).10

Data analysis

Data analysis was done with STATA software version 15.0 (Stata Corporation, College Station, TX, USA), taking the complex sampling design of the GSHS dataset into account. This includes three weighting variables, stratum, primary sampling unit and weight, with the aim of adjusting differences between the “sampled populations and the national student population as a whole and to account for the two-stage sampling method used to select participating schools and classrooms.”9 Data results were described with descriptive statistics. Unadjusted and adjusted multinomial logistic regression was used to estimate associations between independent variables (country, age, gender, hunger, current tobacco use, current alcohol use, ever cannabis use, ever amphetamine use, soft drink consumption, attending physical education classes, truancy, psychological distress, peer and parental support) and one and multiple injuries in the past year, with no injuries in the past year as reference category. Independent variables included were based on a literature review.5 Missing cases were excluded from the analysis. P<0.05 was considered significant.

Results

Sample characteristics

The study sample consisted of 29,480 middle school students (mean age 14.5 years, SD=1.6) from four ASEAN countries, ranging from 3,683 in Laos to 11,142 in Indonesia. The overall response rate ranged from 70% in Laos to 94% in the Philippines.9 The proportion of male students was 48.9% and that of female students 51.1%, and the net enrolment rate in lower secondary school in 2015 in the study countries ranged from 57.1% in Laos to 77.8% Indonesia (see Table 1).

Descriptive results on injury characteristics

The proportion of participants with one or multiple injuries in the past 12 months was 36.9%, 21.4% once and 15.4% multiple times. The most frequent cause of the reported injury was “I fell” (10.2%), followed by motor vehicle (5.8%), “something fell on me or hit me” (2.5%), and “was attacked or abused or was fighting with someone” (2.0%). Boys were more likely to experience one or multiple injuries, motor vehicle, fall and violence-related injuries than girls. The most common injury type was “a broken bone or dislocated joint” (8.1%), followed by “cut, puncture or stab wound” (3.4%), concussion (2.0%) and burns (1.1%). Male students were more likely than female students to have a broken bone or a dislocated joint, a cut, puncture or stab wound and a gunshot wound (see Table 2).

Associations with one and multiple injuries

In adjusted multinomial logistic regression analysis, sociodemographic factors (male sex and experience of hunger, a proxy for low socioeconomic status) and residing in the Philippines and Thailand were positively and residing in Laos was negatively associated with both one and multiple injuries. Substance use (alcohol, tobacco, cannabis, amphetamine and soft drinks) was associated with one and/or multiple injuries. Participating in physical education classes for three or more days a week increased the odds for multiple injuries. Truancy and psychological distress increased the odds for bot one and multiple injuries. High parental or guardian support decreased the odds for one annual injury. Age and peer support were not associated with the prevalence of annual injury (see Table 4).

Discussion

The study provided updated new results and important new observations of the occurrence and socio-psychological correlates of non-fatal injuries in in-school adolescents in the GSHS in four ASEAN countries in 2015. Results indicate a high annual prevalence of injury (36.9%) among school-going adolescents in four ASEAN countries, ranging from 16.8% in Laos and 29.6% in Indonesia to 49.3% in the Philippines and 39.6% in Thailand, which is similar to the annual injury prevalence (40%) in “47 low- and middle-income countries,”7 and lower than in 35 high-income countries (47%).13 The high injury prevalence in the 2015 GSHS in the Philippines (49.3%) was similarly high as found in the 2007 (54.2%) and 2011 (54.3%) GSHS in the Philippines6 and the high injury prevalence in the 2015 GSHS Thailand (39.6%) was lower than in the 2008 GSHS in Thailand (46.8%).4 Compared to the 2008 Indonesia GSHS (45.9%),3 the 2015 GSHS in Indonesia found a lower annual injury prevalence (29.6%). Possible reasons for this decline seem not clear. For example, although from 1990 to 2016 Disability Adjusted Life Yearsdue to injuries decreased, they remain a leading cause of death and disability in Indonesia. The annual injury prevalence in Laos (16.8%) was lower than in any other ASEAN country (Cambodia, Indonesia, Malaysia, Myanmar, Thailand, Vietnam).35 This finding needs further research. Particularly fall injuries were low in Laos (1.2%), but also motor vehiclerelated injuries were lower than in any other of the four countries (3.0%). The lower road traffic injuries may be explained by the low vehicle motorization index, 61.4 vehicles/1,000 population in Laos, compared to 241.6/1,000 population in Thailand in 2015;14 although there has been a stiff increase in vehicle motorization as well as in years of life lost (YLLs) because of road injury from 1990 (rank 20, 1.1% of total YLLs) to 2010 (rank 8, 3% of total YLLs) in Laos.15

Consistent with previous studies,4,1618 the study found that among different causes of injuries, the highest prevalence was fall- and motor vehicle-related injuries. Similar to what was found in other studies,4 this study found that the two most common injury types were “a broken bone or dislocated joint” and “cut, puncture or stab wound.” This underlines the severity of the reported injuries in this population.7

Consistent with previous studies,3,7,8,19,20 male sex increased the odds for one and multiple injuries as well as injuries caused by motor vehicles, fall and being attacked. No sex differences were found for other external causes of injuries (“something fell on me or hit me”, “I was in a fire or too near a flame or something hot” and “I inhaled or swallowed something bad for me”). Further, hunger as an indicator of lower socioeconomic status increased the odds for annual injury prevalence in this study. Similar findings were identified in previous studies.8,18 It is possible that school adolescents with a lower socioeconomic status may experience larger economic deprivation and societal barriers than students from higher socioeconomic backgrounds making them more vulnerable to injuries.21

Consistent with previous studies,4,5,7,20,22,23 this study found an association between psychological distress (loneliness, anxiety, suicidal ideation, suicide attempt and school truancy) and substance use (tobacco, cannabis, amphetamine and soft drinks) were associated with one and/or multiple injury. Some studies24,25 found a link between “frequent soft drink consumption and violent behaviour in adolescents”. Therefore, it may be possible adolescents who frequently drink soft drinks may be more vulnerable to sustain injuries. Increased socio-psychological stress and substance use may have an influencing role in adolescent injury. This finding increased support for adolescent injury interventions that incorporate socio-psychological and legal and illegal drug use issues.26 A previous study20 found a correlation between school and/or home environmental factors and the risk of injury, while this study only found such an association with parental support. The high burden of “injuries on morbidity and mortality” among adolescents and potentially successful prevention activities such as safety training constitutes a high public health priority.1

Study limitations

The study only focused on school-going adolescents which is not representative of all adolescents (including non-school-going adolescents) in ASEAN. The questionnaire utilized was by self-report, which may have introduced a reporting bias, especially the long recall period (12 months) for the occurrence of injuries. Study data were cross-sectional and no causative inferences can be made. Some information, such as the location of the injury, was not assessed and should be assessed in future studies.

Conclusion

This investigation found a high past 12-month prevalence of injury (once and multiple) among a national sample of school adolescents in four ASEAN countries. The study identified several socio-psychological risk factors (male sex, hunger, substance use, truancy, and psychological distress), which may be targeted in an integrated injury prevention program among school adolescents.
