Risk factors for unintentional injuries due to falls in children aged 0-6 years: a systematic review

Socioeconomic, behavioral, and anthropometric risk factors for traumatic dental injuries in childhood: a cohort study

AIM

To investigate risk factors for the occurrence of traumatic dental injuries (TDI) at 4 years of age.

DESIGN

Prospective cohort study.

METHODS

A birth cohort (n = 500) was recruited from the public healthcare system in São Leopoldo, Brazil. Demographic, socioeconomic, anthropometric, and behavioral variables were collected at 6 months, 1 year, and 4 years of age. Clinical examinations at 4 years of age were carried out by a single examiner using the Andreasen classification. Poisson regression was used to determine risk factors for the occurrence of TDI at 4 years of age.

RESULTS

A total of 23.7% of the children (80/337) exhibited TDI at 4 years of age. The risk of TDI was 35% lower among children who had been breastfeed for ≥6 months relative risk (RR 0.65; 95% CI 0.43-0.97) and more than twofold higher among those who were bottle fed ≥ three times a day (RR 2.37; 95% CI 1.10-5.11) at 12 months of age. Higher household income in the first year of life and greater height at 4 years of age were significantly associated with the outcome.

CONCLUSIONS

The identification of behavioral, socioeconomic, and anthropometric risk factors for TDI in early childhood can contribute to the elaboration of prevention strategies.

Paediatric head injuries treated in a children's emergency department from Cluj-Napoca, Romania

The aim of the study was to describe paediatric head injuries and identify factors that led to advanced care. Incident cases of head injuries that sought care from December 2008 to October 2010 at Children's Emergency Hospital Cluj-Napoca were evaluated. The main outcome was transfer or admission to advanced care. From a total of 3053 children treated for an injury, 1541 (50.4%) presented with head injury. A total of 960 (62.3%) of the children with a head injury required advanced care treatment. Young children were more likely to suffer a head injury than older children, but a higher proportion of older children required advanced care (70.3%). Children who suffered a head injury as a consequence of road traffic were almost five times more likely to require advanced care (OR: 4.97; 3.09-8.06) than being released. Our results suggest that data on injuries provide evidence-based information on the nature of injuries children are prone to, and what activity, type, and mechanism of injury impact Romanian children.

Maternal supervision of children during their first 3 years of life: the influence of maternal depression and child gender

OBJECTIVE

The present study examined the effect of child gender and maternal depressive symptoms on routine supervisory practices of mothers longitudinally.

METHOD

Self-report supervision practices were obtained at various time points from 3 months through 3 years of age.

RESULTS

From 3 to 36 months, the quantity of time mothers reported supervising decreased from 7.1 to 6.3 hours, and the proportion of time spent in an intense style decreased from 63 to 46%, whereas that spent in a peripheral style increased from 14 to 32%. Mothers reported more time supervising girls and a greater proportion of this was in an intense style. Mothers with elevated depressive symptoms reported more time supervising but a lower proportion in an intense style.

CONCLUSION

Over the first 36 months of life, routine patterns of supervision change and these vary as a function of maternal depression symptoms and child gender. Implications for child injury risk are discussed.

Epidemiology of paediatric minor head injury: Comparison of injury characteristics with Indices of Multiple Deprivation

BACKGROUND

Head injury (HI) is a common presentation to Child Emergency Departments (CEDs), but the actual number of children attending with minor HI is unclear. Most research has focussed on admitted patients, often relying on hospital-coded admission data. We studied the incidence of minor HI presenting to the CED of a major teaching hospital in Coventry and Warwickshire. HI attendances were compared with population data to identify injury patterns relating to deprivation.

METHODS

All CED admissions were screened by the research team, and data on minor head injuries (GCS 13-15) collected prospectively from 1st January until 31st August 2011. Information was collected on demographics, ethnicity, cause and severity of injury, injury location (in or outside the home), other injuries and mode of arrival. Deprivation data were obtained by cross-referencing postcodes with English Indices of Multiple Deprivation (IMD 2010). For comparison, the hospital audit department provided figures for coded head injuries during the same period.

RESULTS

During the 8 month period, hand-searching identified 1747 children with minor HI, aged between 0 and 16 years. Of these 99% had minimal HI (GCS 15 or 'alert'). In the same period, hospital-coded minor HIs numbered only 1081. HIs formed 9% of all CED attendances. Thirteen children returned to the CED with worrying symptoms after discharge home. Approximately 3.4% of the local paediatric population attend the CED with HI per year (3419/100,000 population). Falls accounted for 62% of HIs overall, rising to 77% in children aged 0-5. Most in-home head injuries (81%) were the result of falls (p<0.0001). Significantly more injuries took place inside the home for 0-5 year olds (58%) than for older children (20%) (p<0.0001). Children living in the most deprived areas were more likely to attend the CED with HI (RR: 1.19; CI: 1.06-1.35, p=0.004), and arrive using emergency services (OR: 1.77; CI: 1.30-2.40, p<0.001). There were no significant differences between the deprived and non-deprived groups for location or cause of injury.

CONCLUSIONS

Young children are particularly at risk of HI and parents should be offered information on injury prevention. More children from deprived areas attended with HI and these families may benefit most from targeted interventions.

Children's perceptions about falls and their prevention: a qualitative study from a rural setting in Bangladesh

Background

Childhood falls is a major public health problem in Bangladesh. In-depth understanding of the situation by the target groups and their families is necessary for successful development, implementation and evaluation of any intervention. The study aimed at knowing the views of Bangladeshi rural children about childhood falls and their suggestions for prevention.

Methods

Children of 10–17 were selected purposely from 4 villages of Sherpur Sadar upazila (sub-district), Sherpur district of Bangladesh. Six focus group discussions and ten in-depth interviews were conducted during July-August 2010 for this study. Gender and education of the participants were considered. Major themes were identified, coded and categorized from content analysis.

Results

Participants stated that young children (<5 years of age) and boys appeared to be the main victims of falls and majority of these injuries occurred in and around the households. Boys commonly fall from the tree around their premises and high places. Girls usually fall when they remain busy in household chores and playing with friends around their premises. Participants also mentioned that children mostly sustained injury when they are unsupervised. Supervision, public awareness and putting barriers (e.g. door barrier, putting pillow and use net around the bed etc.) were suggested as the preventive measures.

Conclusion

Findings of this study could be considered as part of knowledge-base in designing interventions to address childhood falls.

Evaluation of impact of long-lasting insecticide-treated bed nets and point-of-use water filters on HIV-1 disease progression in Kenya

OBJECTIVES

Among HIV-1-infected individuals in Africa, coinfection with malaria and diarrhoeal disease may be associated with more rapid HIV-1 disease progression. We sought to determine whether the use of long-lasting insecticide-treated bed nets and simple point-of-use water filters can delay HIV-1 disease progression.

DESIGN

A prospective cohort study.

SETTING

Two HIV care sites in Kenya.

PARTICIPANTS

HIV-1-infected adults not yet meeting criteria for antiretroviral therapy.

INTERVENTIONS

One group received the standard of care, whereas the other received long-lasting insecticide-treated bed nets and water filters. Individuals were followed for up to 24 months.

MAIN OUTCOME MEASURES

The primary outcome measures were time to CD4 cell count less than 350 cells/μl and a composite endpoint of time to CD4 cell count less than 350 cells/μl and nontraumatic death. Time to disease progression was compared using Cox proportional hazards regression.

RESULTS

Of 589 individuals included, 361 received the intervention and 228 served as controls. Median baseline CD4 cell counts were similar (P=0.36). After controlling for baseline CD4 cell count, individuals receiving the intervention were 27% less likely to reach the endpoint of a CD4 cell count less than 350 cells/μl (hazard ratio 0.73; 95% confidence interval 0.57-0.95). CD4 cell count decline was also significantly less in the intervention group (-54 vs. -70 cells/μl per year, P=0.03). In addition, the incidence of malaria and diarrhoea were significantly lower in the intervention group.

CONCLUSION

Provision of a long-lasting insecticide-treated bed net and water filter was associated with a delay in CD4 cell count decline and may be a simple, practical and cost-effective strategy to delay HIV-1 progression in many resource-limited settings.

[Home falls in infants before walking acquisition]

Minor head trauma is frequent among infants and leads to numerous visits to emergency departments for neurological assessment to evaluate the value of cerebral CT scan with the risk for traumatic brain injuries (TBI).

OBJECTIVES

To analyze the epidemiological characteristics of nonwalking infants admitted after falling at home and to analyze associated factors for skull fractures and TBI.

PATIENTS AND METHODS

Between January 2007 and December 2011, all children aged 9 months or younger and admitted after a home fall to the pediatric emergency unit of a tertiary children's hospital were included. The data collected were age, sex, weight and height, body mass index; geographic origin, referral or direct admission, mode of transportation; month, day and time of admission; causes of the fall, alleged fall height, presence of an eyewitness, type of landing surface; Glasgow Coma Scale (GCS) score, application of the head trauma protocol, location and type of injuries, cerebral CT scan results, length of hospital stay, progression, and neglect or abuse situations.

RESULTS

DESCRIPTIVE ANALYSIS: within the study period, 1910 infants were included. Fifty-four percent of children were aged less than 6 months with a slight male prevalence (52%). Falls from parental bed and infant carriers accounted for the most frequent fall circumstances. GCS score on admission was equal to 14 or 15 in 99% of cases. A cerebral CT scan was performed in 34% of children and detected 104 skull fractures and 55 TBI. Infants aged less than 1 month had the highest rate of TBI (8.5%). Eleven percent of patients were hospitalized. A situation of abuse was identified in 51 infants (3%). UNIVARIATE ANALYSIS: Male children and infants aged less than 3 months had a higher risk of skull fractures (P = 0.03 and P = 0.0003, respectively). In the TBI group, children were younger (3.8 ± 2.6 months versus 5.4 ± 2.5 months, P < 0.0001), fell from a higher height (90.2 ± 29.5 cm versus 70.9 ± 28.7 cm, P < 0.0001), were more often admitted on a weekend or day off, and had more skull fractures (54% versus 6%, P < 0.001). MULTIVARIATE ANALYSIS: all variables showing P < 0.2 in the univariate analysis were entered into the model. In the final model, three variables continued to be associated with a risk of TBI: being referred by a physician (OR 4.6 [2.2-9.6], P < 0.0001), being younger than 3 months old (OR 3.1 [1.7-5.7], P = 0.0002), falling from a height greater than 90 cm (OR 3.1 [1.7-5.6], P = 0.0002).

COMMENTS

Before walking acquisition, children are particularly vulnerable and have the highest rate of TBI after a vertical fall. In this age group, the rate of abuse is also higher. Given this double risk, numerous cerebral CT scans are performed (35-40% of the target population). This protocol, however, leads to a low proportion of detected TBI (<10%) compared to the high number of CT scans and an additional risk of irradiation.

CONCLUSION

As no validated predictive score exists and pending the contribution of the S-100B protein assay, the identification of infants at high risk for TBI and justifying neuroimaging is based on the search for predisposing factors and circumstances.

Travel Medicine

Injuries to children while traveling is an important topic in travel medicine. Traffic injuries and drowning are the first and second leading causes of death in children who travel, and are a far greater risk than infectious and chronic diseases. Effective prevention strategies are available, particularly for travelers who find themselves in unfamiliar environments and who may be unaware of the potential risks to their family. Despite greater understanding and increased research efforts in this field, data on the magnitude and severity of injuries are still incomplete or unreliable in many countries, but some general advice to parents, children, and adolescents can help keep them safe while traveling.

Housing interventions and control of injury-related structural deficiencies: a review of the evidence

Subject matter experts systematically reviewed evidence on the effectiveness of housing interventions that affect safety and injury outcomes, such as falls, fire-related injuries, burns, drowning, carbon monoxide poisoning, heat-related deaths, and noise-related harm, associated with structural housing deficiencies. Structural deficiencies were defined as those deficiencies for which a builder, landlord, or home-owner would take responsibility (ie, design, construction, installation, repair, monitoring). Three of the 17 interventions reviewed had sufficient evidence for implementation: installed, working smoke alarms; 4-sided isolation pool fencing; and preset safe hot water temperature. Five interventions needed more field evaluation, 8 needed formative research, and 1 was found to be ineffective. This evidence review shows that housing improvements are likely to help reduce burns and scalds, drowning in pools, and fire-related deaths and injuries.

Keeping children safe at home: protocol for three matched case-control studies of modifiable risk factors for falls

BACKGROUND

Childhood falls result in considerable morbidity, mortality and health service use. Despite this, little evidence exists on protective factors or effective falls prevention interventions in young children.

OBJECTIVES

To estimate ORs for three types of medically attended fall injuries in young children in relation to safety equipment, safety behaviours and hazard reduction and explore differential effects by child and family factors and injury severity.

DESIGN

Three multicentre case-control studies in UK hospitals with validation of parental reported exposures using home observations. Cases are aged 0-4 years with a medically attended fall injury occurring at home, matched on age and sex with community controls. Children attending hospital for other types of injury will serve as unmatched hospital controls. Matched analyses will use conditional logistic regression to adjust for potential confounding variables. Unmatched analyses will use unconditional logistic regression, adjusted for age, sex, deprivation and distance from hospital in addition to other confounders. Each study requires 496 cases and 1984 controls to detect an OR of 0.7, with 80% power, 5% significance level, a correlation between cases and controls of 0.1 and a range of exposure prevalences.

MAIN OUTCOME MEASURES

Falls on stairs, on one level and from furniture.

DISCUSSION

As the largest in the field to date, these case control studies will adjust for potential confounders, validate measures of exposure and investigate modifiable risk factors for specific falls injury mechanisms. Findings should enhance the evidence base for falls prevention for young children.

Epidemiology of childhood injuries in rural Puducherry, South India

OBJECTIVE

To study the epidemiology of injuries among children (<14 years) in a rural population.

METHODS

The present Cross Sectional Study was undertaken in rural Pondicherry. The trained second year medical undergraduate students paid house visits to all houses in five feasibly selected villages. The students interviewed the mother of children aged < 14 years and obtained information on injuries in last 1 year and its sources of treatments. The authors could obtain information for 1,613 households (96.7%). The data was entered and analyzed using Epi_info 6.04d software package.

RESULTS

Overall, prevalence of injuries among below 14 years was 23% in the last 1 year. The prevalence of injuries among infants, 1-4 years children and 5-14 years children was 32 (15.2%), 110 (24.5%) and 274 (23.7%) respectively. Prevalence of injury was significantly higher among male children (p = 0.001). All injuries were accidental and 68.2% injuries occurred in home environment followed by that in school. Source of treatment for majorities of injuries (58.4%) were government doctors. Notably, village level Anganwadi workers (AWW) or Auxiliary Nurse Midwife (ANM) were not consulted for the treatment. Falls were the leading cause of injury. Fall on ground from height, burns, bite by scorpion/insect/snake/dogs, and road traffic accidents were the four leading causes of injury among children.

CONCLUSIONS

There is a need for community based health education intervention for mothers, caregivers, school teacher and capacity building of village level health workers such as ANM and AWW. Health education message should include preventive measures for the leading causes of childhood injuries.

Pattern of childhood falls in a low-income setting: a cross-sectional study in Dar es Salaam

The objective was to determine patterns and circumstances of childhood falls in a low-income setting in Dar es Salaam, Tanzania. This cross sectional study is based on a household survey conducted in July 2009. A total of 3927 children up to age 18 from 1928 households in 15 sampled wards were surveyed through a structured questionnaire. The current study includes information regarding fall occurrence, socio-demographic and economic factors. Data were analysed using chi-square, t-test and logistic regression. Male children had 42% higher odds of falls compared to females, and rural residents had more than two times higher odds compared to urban residents. Falls occurred three times more among age group 1-4 and two times more among age group 5-9 compared to those between 15 and 18 years. Most falls occurred outdoors (62%) while playing (51%) with boys being over-represented. Females and children aged 1-4 years fell more from stairs whereas most infants fell from furniture. Male gender, younger age groups and rural residence were significant factors for fall injuries. The circumstances in which these falls occur also differ significantly. Intervention efforts should emphasise these patterns.

Unintentional Falls in Older Adults: A Methodological Historical Review

PubMed fournit plus de 6,000 références (700 critiques) sur les chutes accidentelles des personnes âgées. Cet article retrace les jalons principaux et méthodologiques dans l’application de méthodes épidémiologiques depuis les premières publications dans ce domaine, à la fin des années quarante. Dans le contexte des avances faites en définition des cas médicaux, échantillonnage, mesure, conception de la recherche et l’analyse statistique, l’article passe en revue les estimations de fréquence d’apparition, les associations de facteurs de risque, les conséquences de la morbidité et de la mortalité, la démonstration de la théorie des facteurs multirisques à l’aide des interventions sur la prévention des chutes et les défis de modèles de prédiction des risques de chutes. Les explications méthodologiques sont fournies pour les hétérogénéités observées et le cas médical est présenté en faveur d’aller au-delà des listes indifférenciées des facteurs de risque, en mettant l’accent sur l’équilibre et la démarche comme les facteurs par lesquels on peut mieux comprendre les effets mécanistes des facteurs de risque distaux. En outre, l’affaire est faite pour faire avancer nos analyses statistiques en examinant les interactions parmi les facteurs de risque intrinsèques et entre les facteurs intrinsèques, extrinsèques et environnementaux.

The role of community in pediatric injury

Cultural variations between communities may impact injury rates, especially among children. We conducted a retrospective study of three communities in Israel using data from the Israel National Trauma Registry (1998-2007). Pediatric injury hospitalization rates in urban communities with varied levels of socio-economic status (low, medium, and high) were compared for all injuries and cause-specific injuries. Age-standardized and age-specific rates were calculated. Age-standardized injury hospitalization rates were lowest for the low socio-economic status (SES) community (299.7, 95% confidence interval [CI] 289.8-309.6) compared to the medium SES (658.2, 95% CI 629.1-687.3) and high SES (443.7, 95% CI 422.2-465.3) communities. Similar rates were observed for injuries from falls, transportation, accidental striking and intentional causes. For example, rate ratios for falls were 149.1 (95% CI 142.0-156.2), 340.8 (95% CI 319.5-362.1) and 245.7 (229.9-261.5) in the low, medium and high SES communities, respectively. Deviations from these overall trends were noted, however, for pedestrian injuries and burns that were relatively higher in the low SES community and injuries from motorized vehicles that were greater among children living in the high SES community. These results suggest that strong social capital is associated with reduced pediatric injury risks regardless of community wealth. However, targeted interventions for reducing injuries in at-risk populations that rely solely on injury rates may omit culturally distinct communities and overlook their uneven burden to the trauma care system.

Home Injuries: Potential for Prevention

There are approximately 18 000 injury-related deaths at home each year. Some of the leading causes of home injury deaths are falls, fire/ burns, poisonings, choking/suffocations, and drownings. Many more home injuries are treated at emergency departments, in doctors’ offices, or with self-care at home. Children and older adults are especially at risk for home injuries, and environmental factors can contribute to population disparities in home injuries. The causes and circumstances of home injuries are complex and multifaceted. This article provides an overview of the epidemiology and burden of home injuries and reviews the evidence for prevention by life stage. Reducing the risk of injuries at home is challenging, but fortunately there many ways that practitioners can help promote safer behaviors and help change home environments for patients and their families.

Injuries in preschool classrooms

Purpose

The primary purpose of this paper is to examine the kinds of injuries that preschool teachers working in Indiana, USA, believed to be the most common in their preschool (3‐6 year olds) classrooms, the causes of such injuries, and the most important precautions they take to prevent them. Also examined are the measures the teachers take when an injury occurs.

Design/methodology/approach

A total of 155 preschool teachers take part in the research by completing a questionnaire. The data are analyzed using basic descriptive statistics.

Findings

On the question of what constituted the most important classroom injury prevention measure, 26 percent of the respondents report “close supervision of children”, 24 percent select “ensuring classroom safety”, 23 percent pick “cautioning children”, 17 percent choose “setting and enforcing rules” in the classroom, 7 percent select “modeling for social behavior” and 3 percent “safe gross motor activities”. With respect to action taken when an injured occurs, 36.1 percent of the respondents report “first aid”, 15.5 percent “comforting children”, 11.6 percent “referring children to school nurse” and “writing injury report”, 10.3 percent “cautioning against running and pushing”, 8.4 percent “explaining injury to children” (8.4 percent) and 6.5 percent “checking the nature of injury”.

Originality/value

This study sheds light on injury causation in preschool classrooms as well as management of such injuries. Results from this data can be used in helping to improve preschool teachers' knowledge of injury in general and of classroom injury in particular.

Costs, mortality likelihood and outcomes of hospitalized US children with traumatic brain injuries

PRIMARY OBJECTIVE

To examine the hospitalization costs and discharge outcomes of US children with TBI and to evaluate a severity measure, the predictive mortality likelihood level.

RESEARCH DESIGN

Data from the 2006 Healthcare Cost and Utilization Project Kids' Inpatient Database (KID) were used to report the national estimates and characteristics of TBI-associated hospitalizations among US children < or =20 years of age. The percentage of children with TBI caused by motor vehicle crashes (MVC) and falls was calculated according to the predictive mortality likelihood levels (PMLL), death in hospital and discharge into long-term rehabilitation facilities. Associations with the PMLL, discharge outcomes and average hospital charges were examined.

RESULTS

In 2006, there were an estimated 58 900 TBI-associated hospitalizations among US children, accounting for $2.56 billion in hospital charges. MVCs caused 38.9% and falls caused 21.2% of TBI hospitalizations. The PMLL was strongly associated with TBI type, length of hospital stay, hospital charges and discharge disposition. About 4% of children with fall or MVC related TBIs died in hospital and 9% were discharged into long-term facilities.

CONCLUSION

The PMLL may provide a useful tool to assess characteristics and treatment outcomes of hospitalized TBI children, but more research is still needed.

Maternal psychological adjustment and knowledge of infant development as predictors of home safety practices in rural low-income communities

BACKGROUND

Unintentional injury is the leading cause of death among toddlers in the United States. Toddlers spend the majority of time at home, and the use of recommended safety practices can prevent many injuries.

OBJECTIVE

Maternal psychological adjustment and understanding of child development are thought to influence the implementation of safety practices; however, the extent to which either factor is related has been examined with small samples and without attention to potential confounding. We hypothesize that mothers' use of safety practices will be higher when mothers have more knowledge of development and better psychological adjustment.

METHODS

This study is part of the Family Life Project, a longitudinal birth cohort of children from poor rural communities (n = 1611) and an ethnographic sample (n = 36). Mothers in the birth cohort completed scales to measure knowledge of development, psychological adjustment, and home safety practices. Factor analysis of the safety scale resulted in 4 subscales. Each subscale was predicted from maternal knowledge and adjustment in multivariable regression. Mothers in the ethnographic study described sources of information about home safety, current practices, and barriers.

RESULTS

Analyses indicated that mothers with better psychological adjustment were more likely to implement all of the safety practices, and mothers with more knowledge about development were more likely to minimize subtle hazards and install safety devices. An interaction between maternal adjustment and knowledge suggested that mothers with psychological distress were more likely to install safety devices if they had greater knowledge of development. Mothers reported that health care providers were the primary source of safety information, and barriers to implementation included poverty and lack of stable housing.

CONCLUSIONS

Knowledge of development and better psychological adjustment are associated with improved home safety. Knowledge about development is especially important for mothers with poor mental health. Pediatricians and designers of injury-prevention programs should consider the role of maternal mental health in child safety.
