Childhood unintentional injury: The impact of family income, education level, occupation status, and other measures of socioeconomic status. A systematic review

Unintentional poisoning exposures: how does modeling the opening of child-resistant containers influence children's behaviors?

OBJECTIVE

Unintentional poisoning in the home is a risk for children. Over-the-counter medicinal products in child-resistant containers (CRC) are common causes of pediatric poisoning. The current study examined children's abilities to open three types of CRC mechanisms (twist, flip, and push) and corresponding control containers, comparing their ability to do so spontaneously and after explicit modeling. The study also examined if inhibitory control (IC) was associated with children's overall score for spontaneous openings.

METHOD

Children 5-8 years old were randomly assigned to one of three mechanism conditions (between-participants factor): twist, flip, and push, with each child experiencing both a risk and a control container (within-participants factor) having that mechanism. Children were first left alone with a container (measures: engagement with container, spontaneous opening) for up to 2 min and subsequently observed an adult explicitly model opening the container before the child was asked to do so (measure: opening after modeling).

RESULTS

Children were more engaged with and likely to spontaneously open control containers than CRCs, though some (4%-10%) also opened CRCs. After modeling, significantly more children opened each of the three types of CRCs, with nearly all children opening the push mechanism CRC. IC positively predicted children being more engaged with and spontaneously opening more containers.

CONCLUSIONS

Implications for improving pediatric poison prevention are discussed.

Pediatric Trauma Mortality Differs by Neighborhood Opportunity Level

OBJECTIVE

Traumatic injuries are a leading cause of death in children and a child's neighborhood characteristics can be a risk factor. Our objective was to describe the association between pediatric trauma mortality and Child Opportunity Index (COI).

METHODS

A multicenter, retrospective cross-sectional study was conducted across 15 trauma centers from 2010 to 2021 within a large metropolitan county to evaluate trauma activation mortalities involving children <18 years-old. We examined clinical and demographic data from the county trauma registry and linked home zip code to COI, a measure of neighborhood level resources critical for children's development. Proportion of mortalities were compared to the proportion of children within each COI quintile and injury mechanism was evaluated across COI quintile. Analysis was performed using Kruskal-Wallis and chi-square tests (α = 0.05).

RESULTS

Of 31,702 pediatric trauma activations, 513 (1.6%) mortalities occurred. Mortalities mostly resulted from assaults (37.0%), pedestrian injuries (26.7%), and motor-vehicle collisions (18.7%). Of all mortalities, 32.6% were firearm related, either from an assault or self-inflicted. A greater proportion of mortalities were children from very low (47.6%) and low (20.9%) COI neighborhoods with fewer from higher (8.8.% and 7.6%) COI-neighborhoods compared to the county's proportion of children within these quintiles (p < 0.001). The injury mechanisms were different, with mortalities of lower COI neighborhoods being associated with assaults (p = 0.005), while mortalities of higher COI neighborhoods were self-inflicted (p = 0.003).

CONCLUSION

Lower opportunity neighborhoods had a higher incidence of pediatric trauma mortality. Mortality mechanism varied across neighborhoods with assault greater in lower opportunity neighborhoods and self-inflicted among higher opportunity neighborhoods.

Unintentional childhood mortality during emergencies in Israel: a comparative study

BACKGROUND

Armed conflicts are likely to have implications for the welfare and safety of children, potentially leading to increased rates of unintentional childhood injuries.

METHODS

We examine data from Israel concerning the relationship between emergencies and childhood mortality due to unintentional injuries using the media-based database of Beterem Safe Kids Israel to analyse seven events: 2008 Gaza War, 2014 Gaza War, first COVID-19 Lockdown, second COVID-19 Lockdown (September 2020), third COVID-19 Lockdown (December 2020), 2021 Israel-Palestine crisis and 2023 Israel-Gaza War. These events are categorised into Emergency Periods (EPs) and Emergency Routine Periods (periods during which an emergency extends and normalises into a stable routine; ERPs). For each EP we selected a comparable Routine Period (RP).

RESULTS

Unintentional childhood mortality rates are lower during EPs, compared with RPs. Conversely, there is an increase in unintentional mortality rates during ERPs. EPs and ERPs occurring during armed conflicts exhibit higher unintentional mortality rates compared with health-related EPs and ERPs. Furthermore, military-related ERPs show higher unintentional mortality rates compared with the corresponding RPs. Unintentional mortality rates are notably higher among Arab children compared with Jewish children, particularly during ERPs. Unintentional childhood mortality also differs as a function of socioeconomic ranking, with widening gaps between municipalities of low socioeconomic ranking and municipalities of medium to high socioeconomic ranking, during EPs and ERPs.

CONCLUSIONS

We hypothesise that parents' emotional availability declines during EPs and ERPs associated with military conflicts, coinciding with socioeconomic aspects, impacting families' well-being and children's safety.

The Scalding Truth: Geospatial Analysis Identifies Communities at Risk for Pediatric Scald Burns

INTRODUCTION

Pediatric scald burns account for 12% of all U.S. burn center admissions and are the most common type of burn in children. We hypothesized that geospatial analysis of burn registry data could identify specific geographic areas and risk factors to focus injury prevention efforts.

METHODS

The burn registry of a U.S. regional burn center was used to retrospectively identify pediatric scald burn patients ages 0-17, from January 2018 to June 2023. Geocoding of patient home addresses with census tract data was performed. Area Deprivation Index (ADI) was assigned to patients at the census block group level. Burn incident hot spot analysis to identify statistically significant burn incident clusters was done using the Getis Ord Gi∗ statistic.

RESULTS

There were 950 pediatric scald burn patients meeting study criteria. The cohort was 52% male and 36% White, with median age of 3 y and median total body surface area of 1.5%; 23.8% required hospital admission. On multivariable logistic regression, increased child poverty levels (P = 0.004) and children living in single-parent households (P = 0.009) were associated with increased scald burn incidence. Geospatial analysis identified burn hot spots, which were associated with higher ADI (P < 0.001). Black patients were more likely to undergo admission compared to White patients.

CONCLUSIONS

Geospatial analysis of burn registry data identified geographic areas at high risk of pediatric scald burn. ADI, poverty, and children in single-parent households were the greatest predictors of injury. Addressing these inequalities requires targeted injury prevention education, enhanced outpatient support systems and more robust community resources.

Risk factors for severe and fatal childhood unintentional injury: a systematic review protocol

BACKGROUND

Unintentional injuries are a leading cause of death among children aged 1-19 years worldwide. Systematic reviews assessing various risk factors for different childhood injuries have been published previously. However, most of the related literature does not distinguish minor from severe or fatal injuries. This study aims to describe and summarize the current knowledge on the determinants of severe and fatal childhood unintentional injuries and to discuss the differences between risk factors for all injuries (including minor injuries) and severe and fatal injuries. The study also aims to quantify the reduction in childhood injuries associated with a reduction in exposure to some of the identified risk factors in the Canadian population.

METHODS

A systematic review and meta-analysis will be conducted by searching MEDLINE, Embase, CINAHL, and Web of Science. Observational and experimental cohort studies assessing children and adolescents aged ≤ 19 years old and determinants of severe and fatal unintentional injury, such as personal behaviors, family and environmental characteristics, and socioeconomic and geographic context, will be eligible. The main outcome will be a composite of any severe or fatal unintentional injuries (including burns, drowning, transport-related injuries, and falls). Any severity measurement scale will be accepted as long as severe cases require at least one hospital admission. Two authors will independently screen for inclusion, extract data, and assess the quality of the data using the Cochrane ROBINS-E tool. Meta-analysis will be performed using random effects models. Subgroup analyses will examine age subgroups and high- vs low-income countries. Sensitivity analysis will be conducted after restricting analyses to studies with a low risk of bias. Attributable fractions will be computed to assess the burden of identified risk factors in the Canadian population.

DISCUSSION

Given the numerous determinants of childhood injuries and the challenges that may be involved in identifying which individuals should be prioritized for injury prevention efforts, this evidence may help to inform the identification of high-risk children and prevention interventions, considering the disproportionate consequences of severe and fatal injuries. This evidence may also help pediatric healthcare providers prioritize counseling messaging.

The effect of sleep disorders, school jet lag, and anxiety in students 8-10 years of age on traumatic dental injuries

BACKGROUND/AIM

Traumatic dental injuries (TDI) constitute a public health problem. The aim of the present study was to investigate whether sleep disorders, school jet lag, and anxiety are associated with TDI in schoolchildren 8-10 years of age.

METHODS

An analytical, cross-sectional study was conducted with 739 pairs of parents/guardians and children enrolled in public and private schools. The parents/guardians answered a socioeconomic questionnaire, the Sleep Disturbance Scale for Children, Circadian Energy Scale, and Revised Children's Manifest Anxiety Scale. Four examiners underwent calibration exercises for the diagnosis of TDI (K > 0.80) using the criteria proposed by Andreasen (2007). A directed acyclic graph was used for the formulation of the theoretical model and statistical adjustments. Unadjusted and adjusted robust binary logistic regression analyses were performed (α = 5%).

RESULTS

The prevalence of TDI was 16.2%. The following variables remained associated with the outcome in the final model: family income less than or equal to the minimum monthly wage (OR = 1.77; 95% CI: 1.09-2.88; p = .02), child's height >137.6 cm (OR = 1.68; 95% CI: 1.06-2.64; p = .02), the occurrence of school jet lag (OR = 2.12; 95% CI: 1.27-3.53; p = .004), anxiety (OR = 1.77; 95% CI: 1.04-3.00; p = .04) and sleep disorders (OR = 1.63; 95% CI: 1.38-1.93; p = .05).

CONCLUSION

Children from families with a lower income, taller children, those with school jet lag, those with anxiety and those with sleep disorders had a greater occurrence of TDI.

Social and economic factors associated with child unintentional injury mortality in high-income countries

INTRODUCTION

Recognising the connection between country-level social determinants of health, and child unintentional injury mortality can contribute to better resource allocation for child safety. This cross-sectional country-level study aims to investigate such a link where the role of income inequality (Gini Index) is examined alongside education expenditure, current health expenditure and gross national income (GNI) per capita.

METHODS

A total of 49 high-income countries were studied, using the WHO Global Health Estimates 2016, the World Bank's World Development Indicators for education and GNI per capita, and the standardised world income inequality database to compile estimates of child unintentional injury mortality rates and selected socioeconomic characteristics.

RESULTS

A wide range of childhood mortality rates from unintentional injury was observed (1.3-10.0 deaths per 100 000 children). Such risk is strongly associated with income inequality (0.50), GNI per capita (-0.35) and education expenditure (-0.01) (mediated by income inequality). No association was found to current health expenditure. The results explain 52% of the variance in child unintentional injury mortality.

CONCLUSIONS

In countries with higher overall economic activity and lower-income inequality, child mortality from unintentional injuries is lower. Allocation of education expenditure is one contributor to reducing income inequality; other factors need further exploration.

Social determinants of health and disparities in pediatric trauma care: protocol for a systematic review and meta-analysis

BACKGROUND

Social determinants of health (SDH), including "the conditions in which individuals are born, grow, work, live and age" affect child health and well-being. Several studies have synthesized evidence about the influence of SDH on childhood injury risks and outcomes. However, there is no systematic evidence about the impact of SDH on accessing care and quality of care once a child has suffered an injury. We aim to evaluate the extent to which access to care and quality of care after injury are affected by children and adolescents' SDH.

METHODS

Using Cochrane methodology, we will conduct a systematic review including observational and experimental studies evaluating the association between social/material elements contributing to health disparities, using the PROGRESS-Plus framework: place of residence, race/ethnicity/culture/language, occupation, gender/sex, religion, education, socioeconomic status, and social capital and care received by children and adolescents (≤ 19 years of age) after injury. We will consult published literature using PubMed, EMBASE, CINAHL, PsycINFO, Web of Science, and Academic Search Premier and grey literature using Google Scholar from their inception to a maximum of 6 months prior to submission for publication. Two reviewers will independently perform study selection, data extraction, and risk of bias assessment for included studies. The risk of bias will be assessed using the ROBINS-E and ROB-2 tools respectively for observational and experimental study designs. We will analyze data to perform narrative syntheses, and if enough studies are identified, we will conduct a meta-analysis using random effects models.

DISCUSSION

This systematic review will provide a synthesis of evidence on the association between SDH and pediatric trauma care (access to care and quality of care) that clinicians and policymakers can use to better tailor care systems and promote equitable access and quality of care for all children. We will share our findings through clinical rounds, conferences, and publication in a peer-reviewed journal.

Overadjustment bias in systematic reviews and meta-analyses of socio-economic inequalities in health: a meta-research scoping review

BACKGROUND

Overadjustment bias occurs when researchers adjust for an explanatory variable on the causal pathway from exposure to outcome, which leads to biased estimates of the causal effect of the exposure. This meta-research review aimed to examine how previous systematic reviews and meta-analyses of socio-economic inequalities in health have managed overadjustment bias.

METHODS

We searched Medline and Embase until 16 April 2021 for systematic reviews and meta-analyses of observational studies on associations between individual-level socio-economic position and health outcomes in any population. A set of criteria were developed to examine methodological approaches to overadjustment bias adopted by included reviews (rated Yes/No/Somewhat/Unclear).

RESULTS

Eighty-four reviews were eligible (47 systematic reviews, 37 meta-analyses). Regarding approaches to overadjustment, whereas 73% of the 84 reviews were rated as Yes for clearly defining exposures and outcomes, all other approaches were rated as Yes for <55% of reviews; for instance, 5% clearly defined confounders and mediators, 2% constructed causal diagrams and 35% reported adjusted variables for included studies. Whereas only 2% included overadjustment in risk of bias assessment, 54% included confounding. Of the 37 meta-analyses, 16% conducted sensitivity analyses related to overadjustment.

CONCLUSIONS

Our findings suggest that overadjustment bias has received insufficient consideration in systematic reviews and meta-analyses of socio-economic inequalities in health. This is a critical issue given that overadjustment bias is likely to result in biased estimates of health inequalities and accurate estimates are needed to inform public health interventions. There is a need to highlight overadjustment bias in review guidelines.

From unequal injuries to unequal learning? Socioeconomic gradients in childhood concussions and the impact on children's academic performance

Previous research identifies stark socioeconomic disparities in child injuries, yet research on the repercussions hereof on other aspects of children's lives remains sparse. This paper tests whether social gradients in minor traumatic brain injuries (mTBIs or concussions) contribute to corresponding inequalities in children's academic performance. Previous research on this topic is mostly based on small samples and confounded by non-random selection into experiencing mTBIs. We improve on prior research by using high quality, large N, administrative registry data. Further, we control for selection into having an mTBI via comparing the test score progression of children having an mTBI with children who experience an mTBI in later years (staggered difference-in-differences). Based on Danish ER/hospital records and national test score data, we find that children from families with lower earnings and less education are more likely to experience an mTBI and that having an mTBI negatively correlates with reading test scores. However, comparing present with future mTBI cases, we show that having an mTBI within a year before a test does not negatively affect children's reading scores. Our findings suggest that negative correlations between mTBIs and academic performance more likely reflect socioeconomic gradients in mTBI incidents rather than a direct causal effect. Further, socioeconomic gradients in mTBI incidents do not significantly contribute to corresponding disparities in academic performance.

Pediatric Traumatic Brain Injury: Impact on the Developing Brain

Traumatic brain injury (TBI) is a serious public health concern impacting millions of children and adolescents each year. Experiencing a brain injury during key critical periods of brain development can affect the normal formation of brain networks that are responsible for a range of complex neurocognitive outcomes. In addition, there are multiple pre- and postinjury factors that influence the trajectory of recovery and outcomes. In this review, we will focus on the current state of the literature within pediatric TBI; systematically review the available research on developmental aspects of TBI in children, focusing on the pathophysiology of the injury and its impact on the developing brain; and highlight knowledge gaps for further exploration.

Conducting a child injury prevention RCT in the wake of COVID-19: lessons learned for virtual human subjects research

Unintentional injury is the leading cause of death among children in the United States, and children living in low-income households are particularly at risk for sustaining unintentional injuries. Close parental supervision has been found to reduce young children's risk for injury; however, few studies have examined interventions to increase parental supervision. This paper discusses COVID-19 related modifications that were made to a federally funded randomized controlled trial to reduce low-income children's risk for unintentional injury. The study's procedures (data collection and intervention delivery) had to be transitioned from in-person to a fully virtual format. Modifications that were made to the study included use of: participant cell phones to conduct data collection and intervention sessions; virtual meeting software to conduct sessions with participants and; an online platform to collect questionnaire data. In addition, many modifications were required to complete the in-home observation virtually. In terms of feasibility, the investigators were able to collect all of the data that was originally proposed; however, recruitment and retention was more challenging than anticipated. Lessons learned during the modification process are included to provide guidance to researchers seeking to conduct virtual human subjects research in the future.

Neighborhood deprivation and childhood opportunity indices are associated with violent injury among children in Los Angeles County

BACKGROUND

Previous research has demonstrated mixed relationships between individual neighborhood socioeconomic factors and incidences of violence, such as poverty level, population density, and income inequality. We used the Childhood Opportunity Index and Area Disadvantage Index to evaluate the relationship between neighborhood characteristics and the number of incidents of violence among children across the zip codes of Los Angeles (LA) County.

METHODS

We performed a retrospective cross-sectional study of children younger than 18 years from 2017 to 2019 who were entered in the LA County Trauma and Emergency Medicine Information System registry with violent mechanisms of injury, including gunshot, stabbing, or assault. Mechanisms classified as self-inflicted injuries were excluded from the study. The number of incidences of violent mechanism per 100,000 persons younger than 18 years for each zip code was calculated using population data from the US Census American Community Survey 5-Year estimates from 2019. The incidences of violence per capita younger than 18 years for each zip code was compared with the zip code Area Deprivation Index and Childhood Opportunity Index using logistic regression models.

RESULTS

There were 6,791 trauma activations in LA County over the study period, 12.8% (n = 866) of which were due to violence. The mean prevalence of pediatric violent mechanism of injury per zip code was 4 cases per 100,000 persons younger than 18 years. Most injuries were the result of firearms (n = 345 [60.4%]) and occurred among Hispanic/Latino children (n = 362 [57.1%]). There were significantly greater rates of violent injury among children from highest disadvantage (odds ratio, 8.84) and lowest opportunity (odds ratio, 42.48) zip codes.

CONCLUSION

Children living in high disadvantage or low opportunity zip codes had greater rates of violent injury. Further study of neighborhood factors is needed to develop targeted effective interventions to reduce violent injuries among children living in low opportunity areas.

Sociodemographic distribution and correlates of nonfatal unintentional non-traffic-related injuries in Kenya: Results from the 2014 demographic and health survey

Background and Aim

Injuries are among the leading causes of mortality worldwide. There exists a paucity of nationally representative injury data from the sub-Saharan African region on the nature of injuries outside of road traffic contexts. The aim of this study was to estimate the prevalence of nonfatal unintentional injuries that occurred outside of the traffic environment among persons aged 15-54 years in Kenya.

Methods

We used the 2014 Kenyan Demographic Health Survey data to estimate the prevalence of nonfatal unintentional injuries and their injury mechanisms. Binary logistic regression was used to estimate the odds of unintentional injuries and associated factors.

Results

Injury prevalence was three times higher among males (27.56%) compared to females (8.25%). The highest prevalence for females and males respectively was among those aged 15-19 years (9.80%) and (31.18%), rural residents (8.45%) and (30.05%) and those who consumed alcohol (18.13%), and (31.39%). For both females and males, the most frequent injuries were cuts (4.95%; 18.15%) and as result of falls (3.29%; 8.92%) respectively. Burns were more prevalent among females (1.65%) compared to males (0.76%). Among males, the demographic and contextual factors associated with nontraffic unintentional injuries were residing in a rural area (OR 1.33, 95% CI 1.14, 1.56), primary education (OR 2.02, 95% CI 1.48, 2.76), a higher wealth index (second quintile OR 1.41, 95% CI 1.19, 1.67) and consuming alcohol (OR 1.49, 95% CI 1.32, 1.69). Females who had completed primary, secondary (OR 2.43, 95% CI 1.92, 3.08) or higher education had higher odds of unintentional injuries.

Conclusion

The findings mirror prior literature highlighting the clustering of demographic and behavioral factors which underlie predisposition to injuries outside of the traffic environment. Future nationally representative studies would benefit from deeper inquiry into and measurement of injury severity and health care utilization to inform strategic policy-relevant research.

The association between wind speed and the risk of injuries among preschool children: New insight from a sentinel-surveillance-based study

BACKGROUND

Injuries among preschool children are an important public health concern worldwide. Significant gaps remain in understanding the potential impact of wind speed on injuries among preschoolers. We aimed to clarify the association and its variation across subgroups to capture the vulnerability features.

METHODS

Using a case-crossover design and conditional logistic regression model, we compared the exposure to wind speed right before the injury events (case period) with that of control periods to determine the excess rate (ER) of injury on each of 0-3 lag days in Guangzhou, 2016-2020. Results were also stratified by sociodemographic characteristics of patients, basic characteristics of injury events, and clinical features of injuries to identify the most vulnerable subgroups of preschoolers.

RESULTS

Higher wind speed was significantly associated with an increased risk of injuries among preschoolers on lag 0, reaching an ER of 2.93 % (95 % confidence interval [CI] = 0.87, 5.03), but not on other lag days. The results of the stratified analyses showed that children under 3-year-old (3.41 %; 95 % CI = 0.36, 6.55), boys (3.66 %; 95 % CI = 1.04, 6.35), and non-locally registered children (3.65; 95 % CI = 0.02, 7.40) were more prone to wind-related injuries. Falls (2.67 %; 95 % CI = 0.11, 5.30) were the main cause of wind-related injuries, and taking transportation was the main activity when injuries occurred (13.16 %; 95 % CI = 4.45, 22.60). Additionally, injuries involving buildings/grounds/obstacles (4.69 %; 95 % CI = 1.66, 7.81) and the occurrence of sprain/strain (7.60 %; 95 % CI = 0.64, 15.04) showed a positive association with wind speed.

CONCLUSIONS

Higher wind speed was associated with a significantly elevated rate of injuries among preschoolers without delayed effects, where children under 3-year-old, boys, and non-locally registered subgroups were more susceptible to wind-related injuries. This study may provide new insights for refining the prevention measures against wind-related injuries among preschoolers.

Scoping review of children's and youth's outdoor play publications in Canada

INTRODUCTION

Since 2015, interest in the benefits of outdoor play for physical, emotional, social and environmental health, well-being and development has been growing in Canada and elsewhere.

METHODS

This scoping review aims to answer the question, "How, and in what context, is children's and youth's outdoor play being studied in Canada?" Included were studies of any type on outdoor play published after September 2015 in English or French by authors from Canadian institutions or assessing Canadian children and/or youth. Articles retrieved from MEDLINE, CINAHL and Scopus by March 2021 were organized according to eight priority areas: health, well-being and development; outdoor play environments; safety and outdoor play; cross-sectoral connections; equity, diversity and inclusion; professional development; Indigenous Peoples and land-based outdoor play; and COVID-19. Within each priority, study design and measurement method were tallied.

RESULTS

Of the 275 articles included, the most common priority area was health, wellbeing and development (n = 239). The least common priority areas were COVID-19 (n = 9) and Indigenous Peoples and land-based outdoor play (n = 14). Cross-sectional studies were the most common; the least common were rapid reviews. Sample sizes varied from one parent's reflections to 999 951 data points from health databases. More studies used subjective than objective measurement methods. Across priorities, physical health was the most examined outcome, and mental/emotional development the least.

CONCLUSION

A wealth of knowledge on outdoor play in Canada has been produced since 2015. Further research is needed on the relationship between outdoor play and mental/emotional development among children and youth.

Tailoring a Child Injury Prevention Program for Low-Income U.S. Families

Objective

Unintentional injuries are the leading cause of death for children in the United States (U.S.), and young children ages (1-4) are particularly at risk. Supervising for Home Safety (SHS) is a Canadian intervention that has been shown to reduce children's injury risk by increasing caregiver supervision. Given that low-income children are at greatest risk for injury, this study describes a process of modifying the SHS program to be culturally appropriate for low-income families of U.S. preschool children.

Methods

Two rounds of focus groups were completed; feedback from the first round of focus groups was used to modify program materials prior to the second round.

Results

Caregivers gleaned important take-away messages from both the original and modified materials, including the idea that injuries can happen quickly and that caregivers can prevent injuries. Modifications to the intervention included increased diversity in the families represented in the videos as well as inclusion of U.S. injury statistics. Caregivers in both rounds of focus groups noted that the program messages were relatable and realistic and that the materials were impactful in increasing their awareness of children's injury risk.

Conclusion

We were able to successfully modify the SHS program to be appropriate for low-income U.S. families while preserving the core program messages.

Troublesome behaviour and traumatic dental injuries during adolescence

BACKGROUND/AIM

Troublesome behaviour can lead to bodily injuries among young people, although a link with traumatic dental injuries (TDIs) remains unclear. The aim of this study was to evaluate the longitudinal association between troublesome behaviour and TDIs during adolescence.

METHODS

This study analysed data from phases 2 and 3 of the Research with East London Adolescents Community Health Survey (RELACHS), a longitudinal study of public secondary schools in East London. Troublesome behaviour in the past 12 months was measured with 8 items (told lies to get things from others, started fight, bullied or threatened people, stayed late outside, stole valuable things, ran away from home, played truant from school and intentionally destroyed someone else's property) from the Development and Well-Being Assessment (DAWBA), when participants were 13-14 years old (Phase 2). Adolescents were dentally examined for TDIs when they were 15-16 years old (Phase 3). The association between troublesome behaviour and TDIs was tested in logistic regression models adjusting for socio-demographic characteristics and oral clinical factors.

RESULTS

Forty-three per cent of adolescents reported one or more troublesome behaviours at age 13-14 years, and 16% had evidence of TDIs by age 15-16 years. Adolescents who answered 'perhaps' and 'definitely' to any troublesome behaviour item had, respectively, 1.37 (95% CI: 0.62-3.00) and 1.50 (95% CI: 0.69-3.30) greater odds of having TDIs than those who answered 'no' after adjustment for confounders. Of the 8 behaviours assessed, having run away from home, bullied or threatened people, often told lies, and stolen valuable things were associated with having TDIs.

CONCLUSION

This study among adolescents shows that reporting troublesome behaviour was associated with TDIs two years later. Given the wide confidence intervals for these associations, the present findings require confirmation from further longitudinal studies.
