Abstract
BACKGROUND AND OBJECTIVES Crash injury risk is reduced when a child correctly uses an appropriate restraint; however, incorrect restraint use remains widespread. The aim of this study was to determine whether product information developed using a user-driven approach increases correct child restraint use. METHODS We conducted a two-arm double-blinded parallel randomised controlled trial in New South Wales, Australia 2019-2021. Participants were current drivers who were either an expectant parent or a parent of at least one child residing in the greater Sydney metropolitan area who were interested in purchasing a new child restraint. The intervention was user-driven product information consisting of instructions printed on an A3 sheet of paper, swing tags with key reminders and a video accessed via Quick Response codes printed on the materials. The control group received a postcard summarising legal child restraint requirements. The primary outcome was the correctness of child restraint use observed during home visit approximately 6 months after restraint purchase. Correct use was defined as no serious error or <2 minor errors. The secondary outcome was a count of observed errors. RESULTS 427 participants were recruited. Home visits were conducted for 372 (190 intervention and 182 control). Correct use was more common in the intervention group (37.4%) compared with the control group (24.2%, p=0.006). Participants receiving the intervention were 1.87 times more likely to correctly use their restraint than those in the control group (95% CI 1.19 to 2.93). CONCLUSIONS The results provide evidence for the effectiveness of user-driven instructions as a countermeasure to restraint misuse. TRIAL REGISTRATION NUMBER ACTRN12617001252303.

Updated population-level estimates of child restraint practices among children aged 0-12 years in Australia, 10 years after introduction of age-appropriate restraint use legislation. Inj Prev 2024; 30:100-107. [PMID: 38050054 DOI: 10.1136/ip-2023-044994] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2023] [Accepted: 10/13/2023] [Indexed: 12/06/2023]
Abstract
OBJECTIVE Optimal child passenger protection requires use of a restraint designed for the age/size of the child (appropriate use) that is used in the way the manufacturer intended (correct use).This study aimed to determine child restraint practices approximately 10 years after introduction of legislation requiring correct use of age-appropriate restraints for all children aged up to 7 years. METHODS A stratified cluster sample was constructed to collect observational data from children aged 0-12 years across the Greater Sydney region of New South Wales (NSW). Methods replicated those used in a similar 2008 study. Population weighted estimates for restraint practices were generated, and logistic regression used to examine associations between restraint type, and child age with correct use accounting for the complex sample. RESULTS Almost all children were appropriately restrained (99.3%, 95% CI 98.4% to 100%). However, less than half were correctly restrained (no error=27.3%, 95% CI 10.8% to 43.8%, no serious error=43.8%, 95% CI 35.0% to 52.7%). For any error, the odds of error decreased by 39% per year of age (OR 0.61, 95% CI 0.46 to 0.81) and for serious error by 25% per year (OR 0.75, 95% CI 0.60 to 0.93). CONCLUSION The findings demonstrate high levels of appropriate restraint use among children across metropolitan Sydney approximately 10 years after introduction of legislation requiring age-appropriate restraint use until age 7, however, errors in the way restraints remain common. IMPLICATIONS FOR PUBLIC HEALTH Given the negative impact incorrect use has on crash protection, continuing high rates of incorrect use may reduce effectiveness of legislative change on injury reduction.

Differences in participant characteristics and observed child restraint use between population-based and restraint fitting service samples. TRAFFIC INJURY PREVENTION 2023; 24:693-699. [PMID: 37585680 DOI: 10.1080/15389588.2023.2234532] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/03/2022] [Revised: 07/03/2023] [Accepted: 07/05/2023] [Indexed: 08/18/2023]
Abstract
OBJECTIVE To compare characteristics and restraint use between a population-based and fitting service sample of child restraint users. METHOD Characteristics of the two samples were compared using chi-squared tests. Differences in errors in restraint use observed in the two samples were modeled using logistic regression. RESULTS There were significant differences in child age (p < 0.001), and restraint types (p < 0.001) between the two samples, with more younger children in the fitting service sample. Controlling for differences in restraint type, the odds that adult participants were female were 61% less in the fitting service sample than in the population-based sample (OR 0.39, 95%CI 0.21-0.71). The odds that adult participants perceived a large risk associated with restraint misuse (OR 3.62, 95%CI 1.33-9.84), had a household income in the highest bracket (OR 3.89, 95%CI 1.20-12.62) and were living in areas of highest socioeconomic advantage (OR 2.72, 95%CI 1.22-6.06) were approximately three times higher in the fitting service sample. Overall, more participants had errors in restraint use in the population-based sample (p = 0.021). However, after controlling for restraint type, securing errors were three times more likely (OR 3.34, 95%CI 1.12-10.2), and serious installation errors were almost twice as likely (OR 1.91, 95% CI 1.09-3.39) in the fitting service sample. CONCLUSIONS While less resource intensive, convenience and/or fitting service samples may be less representative than population-based samples. Given the need for efficiency, methods that combine randomized population-based invitations to participate in restraint fitting check day events across geographically representative areas may be useful for ongoing surveillance of child restraint use.

Abstract
Objective To quantify the extent of proper local child restraint system (CRS) use and to better understand changes to the level of self-reported confidence with increased CRS installations. With the goal being to improve safety for children travelling in personal vehicles across London, ON and the region. Methods Public CRS clinics were initiated by Injury Prevention staff after they obtained the Child Passenger Safety Technician certification. Additionally, an online survey was commissioned targeting Ontario parents who had installed at least one CRS in the last five years. Results From September 2018 to September 2019, 96 comprehensive CRS checks were performed, with 29% of systems found to be installed correctly. Survey results showed a high level of reported confidence with CRS installation (N = 514, 70% female, 43% one child). Parents who had installed only one CRS reported higher confidence in their first install, compared to parents who had installed two or more systems. Conclusions The error rate with CRS installation and use seen in London, Ontario and the region, is similar to that reported in previous research. Survey results showed high levels of self-reported confidence in CRS use, especially for parents who have installed only one CRS. There presents a need to better understand the root cause of the discrepancy between level of confidence and proper CRS use and to expand our understanding of CRS knowledge retention and transferability to subsequent systems.

Head excursion in frontal impacts is lower in high back booster seats than in forward facing child seats with internal harnesses designed for children up to 8 years of age. TRAFFIC INJURY PREVENTION 2022; 23:244-249. [PMID: 35333678 DOI: 10.1080/15389588.2022.2048825] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/25/2021] [Revised: 02/27/2022] [Accepted: 02/28/2022] [Indexed: 06/14/2023]
Abstract
OBJECTIVE It is often assumed that a child restraint with a five or six-point internal harness provides greater protection for children in frontal crashes than a booster seat with a lap-sash seat belt. However, most research comparing these restraint types has focused on protection for children aged up to approximately 3-4 years of age. Recently, harnessed child restraints for older children up to approximately 8 years of age have become available, but there is little data on their performance compared to booster seats for children over 4 years of age. This study aimed to compare frontal crash performance of a series of harnessed child restraints for children aged 4-8 years to booster seats. METHODS Four large harnessed child restraints (Type G in the Australian Standard, AS/NZS 1754:2013) and six high back booster seats (Type E in AS/NZS 1754:2013) were tested in frontal impact on a deceleration sled. Head and pelvis accelerations were recorded and head excursions were measured from high speed video. RESULTS Head excursion was an average of 92 mm greater in the large harnessed child restraints than the high back booster seats. The initial position of the head in Type G restraints, an average of 58 mm further forward compared to Type E boosters, was the main contributor to the larger head excursion during impact. Conversely, peak head accelerations in the impact phase were, on average, 37.2 g lower in the large harnessed child restraints than the high back booster seats. CONCLUSIONS These data suggest that recommendations for harnessed restraints and booster seats for children aged 4-8 years is not as obvious as is sometimes assumed. Harnessed restraints allow greater head excursion in frontal impacts, potentially increasing the chances of head impacts, especially in vehicles with limited clearance between the restraint and the seat in front. The likelihood, and types of, incorrect use that occur in each restraint type, the vehicle occupant space, and the restraint's crash performance under ideal conditions should be considered in recommending restraints for these older children.

TRAFFIC INJURY PREVENTION 2022; 23:91-96. [PMID: 35044289 DOI: 10.1080/15389588.2021.2012168] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/28/2021] [Revised: 11/25/2021] [Accepted: 11/25/2021] [Indexed: 06/14/2023]
Abstract
OBJECTIVE To compare how errors in child restraint use influence crash injury risk in rearward and forward-facing restraints for a 1-year old occupant. METHODS Three convertible child restraint systems (CRS) were subjected to frontal dynamic sled tests at 56 km/h in rearward-facing and forward-facing modes in a correct use (baseline) condition and in five incorrect use conditions: loose securing belt, loose harness, partial harness use, top tether slack, and three minor errors. Excursion, head, and chest 3 ms resultant acceleration, HIC15, and neck forces and moments of a Q1 anthropomorphic test device (ATD) seated in the restraints were measured. The effect of incorrect use on each outcome and restraint type was analyzed. RESULTS The influence of errors varied across different outcome variables, the three restraints tested and orientation modes. Excursion increased in four of five incorrect use conditions in both rearward and forward-facing orientations. A very loose harness increased four of five outcome variables in at least one forward-facing restraint, whereas only excursion was increased when rearward-facing. Overall, there tended to be a more negative effect of incorrect use (demonstrated through increases in outcome variables compared to the baseline) in the forward-facing orientation. CONCLUSIONS Overall, errors in use tended to have a larger negative impact on forward-facing restraints than rearward-facing restraints. Given the widespread nature of errors in use, this adds further weight to arguments to keep children rearward-facing to 12 months of age and older. The results also highlight a variation in response to errors across differently designed restraints, suggesting the influence of errors may be minimized by restraint design that is more resistant to errors.

TRAFFIC INJURY PREVENTION 2021; 22:634-639. [PMID: 34714192 DOI: 10.1080/15389588.2021.1980562] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/09/2021] [Revised: 09/09/2021] [Accepted: 09/10/2021] [Indexed: 06/13/2023]
Abstract
OBJECTIVE To minimize children's injuries due to car accidents, children must be transported in approved child restraint systems (CRS). The European Union optimized child protection by implementing R129 legislation for CRS in 2013. However, compliance with CRS recommendations after introduction of this newer standard has been scarcely evaluated. The main objectives of this study were to determine the prevalence of various types of CRS misuse and to investigate the use of ISOFIX and i-Size seats and parental knowledge regarding safe transportation of children in cars 5 years after the introduction of the newer R129 standard. METHODS During a cross-sectional observational study in the summer of 2018, parking lots of sites in the Netherlands were visited by researchers. Arriving or departing Dutch drivers who transported children under 9 years old were interviewed by means of a questionnaire and the misuse of CRS was directly observed using a checklist. Misuse was defined as CRS inappropriate for the child (based on height and weight) and/or CRS wrongly installed in the car and/or child improperly restrained in CRS. RESULTS In total, 392 drivers and 470 children were included in the study. Results showed that 83% of the children were transported with at least 1 misuse of their CRS: 7% of the CRS were inappropriate for the child, 49% of the CRS were wrongly installed in the car, and 59% of the children were improperly restrained in a CRS. Most CRS were installed using the seat belt (88%) compared to ISOFIX (12%). ISOFIX usage did not result in less CRS installation misuse (P = .338). The number of observed i-Size CRS was low (n = 13, 3%). Most drivers were familiar with ISOFIX (76%), but only 13% of the drivers had heard of i-Size. CONCLUSIONS For 9 out of 10 children, CRS misuse was observed. Many children were transported in an appropriate CRS, but various mistakes were made when installing the CRS in the car and restraining children in the CRS. Moreover, ISOFIX usage did not result in statistically significant less CRS installation misuse compared to traditional seat belt usage, and i-Size CRS are still rather unknown 5 years after their introduction.

Abstract
Background The motor vehicle crash (MVC) is a major cause of injuries and deaths among children worldwide. The child restraint system (CRS) is designed to protect children from injury and death if passengers are involved in MVC. Objectives To determine the prevalence of CRS use for children aged 5 years and below and to explore the pattern of child transportation inside cars in Buraidah, Saudi Arabia. Methods A cross-sectional study was conducted using a self-administered questionnaire distributed among parents attending primary healthcare centers. Simple random sampling was used to select 330 participants. The survey was conducted from January to March 2020. Results A total of 135 (40.9%) respondents had CRS available in their cars, and only 51 (15.5%) participants reported using it 'always'. Child discomfort, difficulty in handling CRS, and being unaware of CRS importance were the commonly reported reasons of not using CRS. The most common practiced mode of transportation, in case of not using CRS, was seating the child in the front seat on an adult lap. Twenty-eight (8.2%) respondents experienced a MVC while driving with a child; half (53.6%) of these were not using CRS at the time of the accident. Less than half (47.1%) of the participants were aware of the CRS law in Saudi Arabia. Conclusion The prevalence of using CRS is low. Creating awareness among parents and strict implementation of the CRS law can lead to increase in the use of CRS which will lead to prevention of traffic-related injuries and deaths among children.

What Are the Restraint Practices, Preferences, and Experiences When Australian Parents Travel with Their Children in a Rideshare Vehicle? INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18178928.

Abstract
This study aimed to explore the preferences, experiences and restraint practices of Australian parents travelling with their children in rideshare vehicles. Six hundred and thirty-one participants completed an online survey (M = 39.2 years, SD = 10.5, Range = 18.0–70.0 years; Female: 63.4%). Most participants (59.1%) reported that they had not travelled in a rideshare vehicle with their youngest child (M = 7.2 years, SD = 5.2, Range = 0.0–17.0 years; Male: 54.2%). Participants who reported that they have travelled with their youngest child in a rideshare vehicle tended to: be younger, identify as male, have completed an Undergraduate or Postgraduate degree, reside in the Australian Capital Territory, earning a higher yearly household income, and were involved in an at-fault crash in the past two years. In addition, these participants were: less likely to have a ‘younger’ youngest child, less likely to ‘always’ wear a seatbelt while travelling in their private motor vehicle, and also less likely to ‘always’ restrain their child in an appropriate restraint while travelling in their private motor vehicle. Prohibitive reasons for not travelling in a rideshare vehicle included: cost (29.3%), concerns over driver safety (27.5%), concerns over travelling with children in a rideshare service (24.8%), or inconvenience (24.3%). Participants who reported that they had travelled in a rideshare vehicle with their youngest child reported lower rates of appropriate restraint use within the rideshare vehicle (57.3%) than when travelling in their private motor vehicle (85.6%). Reasons associated with inappropriate restraint use within the rideshare vehicle included: unavailability of a child restraint (39.6%), travelling a short distance (33.0%), were not required to use one in this situation (33.0%), or the parent did not have a restraint with them (26.4%). Given the increasing popularity of rideshare services in Australia, and globally, the urgent adaption of rideshare-specific policy, legislation, education, and design in relation to child restraint requirements is needed to ensure the safety of child occupants.

A Process Evaluation Protocol for Examining the Impact of Instructions for Correct Use of Child Car Seats Designed through a Consumer-Driven Process and Evaluated in a Field-Based Randomised Controlled Trial. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17124508. [PMID: 32585923 PMCID: PMC7345236 DOI: 10.3390/ijerph17124508] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/27/2020] [Revised: 05/22/2020] [Accepted: 05/28/2020] [Indexed: 11/16/2022]
Abstract
The incorrect use of child car seats is common, with significant negative effects on crash protection for child passengers. There is currently little evidence for effective, practical countermeasures for incorrect use. The provision of clear and comprehensible materials on correct use supplied with restraints at the point of sale could be highly cost-effective and achieve similar benefits to restraint-fitting services or hands-on training; however, routinely supplied instructions in their current form are frequently difficult to understand. We are conducting a randomised controlled trial of the consumer-driven redesign of instructional materials, consisting of an instruction sheet, swing tags and online training videos. This paper presents the protocol that will be used in an innovate process evaluation that will use the primary outcome of overall serious misuse assessed at six months, together with a survey and semi-structured interviews to determine fidelity, dose and outcomes for all intervention participants. The study will assess intervention delivery and external factors that may impact the effectiveness of the intervention, including experience, health literacy, confidence and attitudes. When it has been conducted, this process evaluation will provide enhanced understanding of the mechanisms through which the intervention works or not, aspects of the implementation process key to success of the intervention and insight into how external factors influence the success of the intervention.

Restraint Factors and Child Passenger Deaths in New South Wales, Australia. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17041147. [PMID: 32059428 PMCID: PMC7068408 DOI: 10.3390/ijerph17041147] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/29/2019] [Revised: 01/31/2020] [Accepted: 02/07/2020] [Indexed: 11/30/2022]
Abstract
Inappropriate or incorrect use of child restraints can influence crash injury outcome. This study examined the role of restraint factors in child passenger deaths and the effect of legislation requiring appropriate restraint systems up to 7 years old. Data for child (0–12 years) passenger deaths occurring in New South Wales (NSW) from 2007 to 2016 were collected by the child death review team including photographs, reports of in-depth crash investigation, witness reports and medical reports. Restraint use, type of restraint, appropriateness of the restraint for the age of the child and correctness of restraint use were examined. The primary contributor to death was determined in each case. Sixty-four child passengers died in NSW during the data period. Twenty-nine (29/64, 45%) were properly restrained. Thirteen children (13/64, 20%) were unrestrained. In 20 cases (20/64, 31%), children were using a restraint that was either inappropriate for their age (6) or not used correctly (14). Restraint factors were a primary contributor in 22 (22/64, 34%) child deaths. Compared to pre-legislation, appropriate restraint use was more common post-legislation (13/22. 59% vs. 30/42, 71%). However, incorrect use was also greater (3/22, 14% vs. 11/42, 26%). Interventions targeting increasing restraint use and reduction of common ‘use’ errors are needed to prevent further restraint factor-related deaths.

Abstract
Objective: Road traffic accidents are a global issue and serious threat for public health. Children are at high risk of serious injury or death from motor vehicle crashes. Child safety seats (CSSs) can reduce the risk of death and serious injury in children. This study was done to determine the prevalence of child safety seat use in vehicles and the factors influencing their use in a safe society (Tehran, Iran) in 2015.Methods: In this cross-sectional study, 804 parents with children under 12 years old who owned private cars were questioned in different areas of Tehran. A questionnaire included demographic data, and 2 specific questionnaires were used for families that used a CSS and those did not use a CSS. Univariate and multivariate binary logistic regression analyses were conducted. Crude and adjusted odds ratios (AORs) with 95% confidence intervals (CIs) were calculated. All analyses were carried out using SPSS 21.Results: The prevalence of child safety seat use was 18.7% and was significantly higher among parents with an income greater than 50 million rials/month, parents who received child safety seat recommendations, parents living in the north of Tehran, and fathers with more driving experience. Age, weight, and height of children were also factors that influenced the use of child safety seats. The most common reasons for parents to use child safety seats was awareness about the benefits of this device and fear of harm to the child, and the most common reasons for nonuse were child intolerance while sitting in the seat and cost.Conclusion: The prevalence of child safety seat use in Tehran is very low, and most parents are not aware of the importance of child safety seats. Comprehensive programs, including legislation, law enforcement, public education, and publicity to promote the benefits of using CSSs, in Tehran can be an effective step toward increasing the use of child safety devices.

Abstract
BACKGROUND Incorrect use of child restraints is a long-standing problem that increases the risk of injury in crashes. We used user-centred design to develop prototype child restraint instructional materials. The objective of this study was to evaluate these materials in terms of comprehension and errors in the use of child restraints. The relationship between comprehension and errors in use was also explored. METHODS We used a parallel-group randomised controlled trial in a laboratory setting. The intervention group (n=22) were provided with prototype materials and the control group (n=22) with existing instructional materials for the same restraint. Participants installed the restraint in a vehicle buck, secured an appropriately sized mannequin in the restraint and underwent a comprehension test. Our primary outcome was overall correct use, and our secondary outcomes were (1) comprehension score and (2) percent errors in the installation trial. RESULTS There was 27% more overall correct use (p=0.042) and a higher mean comprehension score in the intervention group (mean 17, 95% CI 16 to 18) compared with the control group (mean 12, 95% CI 10 to 14, p<0.001). The mean error percentage in the control group was 23% (95% CI 16% to 31%) compared with 14% in the intervention group (95% CI 8% to 20%, p=0.056). For every one point increase in comprehension, there was an almost 2% (95% CI -2.7% to -1.0%) reduction in errors (y=45.5-1.87x, p value for slope <0.001). CONCLUSIONS Consumer-driven design of informational materials can increase the correct use of child restraints. Targeting improved comprehension of informational materials may be an effective mechanism for reducing child restraint misuse.

Abstract
Objective: Child occupant behavior and head position when travelling in child restraint systems (CRS) may have an effect on injury risk in the event of a motor vehicle crash. The current study aimed to describe the common characteristics and behaviors of child occupants during everyday, real-world motor vehicle travel in a sample of Australian families to identify potential safety implications of observed behaviors and head position within the CRS. Methods: Two instrumented study vehicles were used by 42 families for approximately two weeks. Continuous video and audio data were collected across 1,651 trips (over 600 hours). An online survey provided additional parent, familial and child occupant data. The characteristics and behaviors of 72 child occupants (aged 14 months to 9 years) who travelled in a forward-facing CRS (FFCRS) or a belt-positioning booster seat (BS) were observed and recorded by manual review of a sample of the video/audio recordings. One quarter of all trips (n = 414) was randomly selected for coding/analysis and, within each trip, one child occupant was selected who was travelling in a FFCRS or BS. Child occupant behaviors, head position within the FFCRS or BS, and other relevant information was coded for each trip during nine discrete five second intervals or 'epochs' (5%, 17%, 25%, 30%, 50%, 53%, 75%, 89% and 95% of trip duration). Results: In the majority of epochs (74%), child occupants' heads were observed to be 'optimally' positioned within the FFCRS or BS. For more than half of the epochs, child occupants were observed to be: correctly restrained (58%) and involved in an interaction with another vehicle occupant (59%). Bivariate analyses revealed that children travelling in a FFCRS were significantly more likely to be observed to have optimal head positions than those travelling in a BS (78% vs. 62%), χ2 (1) = 86.00, p < 0.001. Child occupants who were observed to be 'correctly' restrained were significantly more likely to be observed to have optimal head positions than those who were observed to be 'incorrectly' restrained (80% vs. 20%), χ2 (1) = 10.33, p < 0.01. Conclusions: This is the first naturalistic driving study (NDS) to specifically explore the factors associated with child occupants' head position when travelling in a CRS. Findings from the current study can be used to inform the positioning of anthropometric test dummies (ATD) in CRS testing, guide improvements to CRS/vehicle design, and develop targeted educational strategies to improve child occupant safety.

Abstract
Objective: Cross-chest clips are widely used in North American child restraints but are less common in other countries, partially due to concerns over anterior neck contacts in frontal crashes. They have recently been reported to be associated with lower odds of injury in real-world crashes, but there is a paucity of crash test performance information. This study aimed to compare the dynamic performance of a small child occupant in frontal crash tests with and without cross-chest clips in place. Methods: Frontal sled tests at 49 km/h were conducted to compare 2 cross-chest clip designs to nonuse of a chest clip. Tests using a P3/4 anthropomorphic test device (ATD) to represent the smallest occupant in a forward-facing child restraint were conducted with the chest clips in the recommended position and also in an incorrect lower position and with and without additional harness slack present. Results: Though contacts were observed between the chest clips and the base of the ATD's neck, there was little difference observed in head excursion or ATD sensor loads in the presence of the chest clips. No detectable change in the neck forces or moments was detected at the time of the neck contacts. The position of the clips did not affect the results. Harness slack increased head excursion, as expected, but this effect did not differ between the tests with and without the clips. Conclusions: Cross-chest clips do not appear to greatly influence the dynamic performance of a forward-facing child restraint in a simulated frontal crash. Taken together with recent research suggesting a potential benefit in injury reduction from the clips in the real world, possibly due to maintaining the harness straps in place on a child's shoulders, it may be appropriate to re-evaluate safety standards that prevent their use.

[PMID: 29185794 DOI: 10.1080/15389588.2017.1410545] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/15/2017] [Accepted: 11/23/2017] [Indexed: 06/07/2023]
Abstract
OBJECTIVE Traffic crashes have high mortality and morbidity for young children. Though many specialized child restraint systems improve injury outcomes, no large-scale studies have investigated the cross-chest clip's role during a crash, despite concerns in some jurisdictions about the potential for neck contact injuries from the clips. This study aimed to investigate the relationship between cross-chest clip use and injury outcomes in children between 0 and 4 years of age. METHODS Child passengers between 0 and 4 years of age were selected from the NASS-CDS data sets (2003-2014). Multiple regression analysis was used to model injury outcomes while controlling for age, crash severity, crash direction, and restraint type. The primary outcomes were overall Abbreviated Injury Score (AIS) 2+ injury, and the presence of any neck injury. RESULTS Across all children aged 0-4 years, correct chest clip use was associated with decreased Abbreviated Injury Scale (AIS) 2+ injury (odds ratio [OR] = 0.44, 95% confidence interval [CI], 0.21-0.91) and was not associated with neck injury. However, outcomes varied by age. In children <12 months old, chest clip use was associated with decreased AIS 2+ injury (OR = 0.09, 95% CI, 0.02-0.44). Neck injury (n = 7, all AIS 1) for this age group only occurred with correct cross-chest clip use. For 1- to 4-year-old children, cross-chest clip use had no association with AIS 2+ injury, and correct use significantly decreased the odds of neck injury (OR = 0.49; 95% CI, 0.27-0.87) compared to an incorrectly used or absent cross-chest clip. No serious injuries were directly caused by the chest clips. CONCLUSIONS Correct cross-chest clip use appeared to reduce injury in crashes, and there was no evidence of serious clip-induced injury in children in 5-point harness restraints.

Abstract
Motor vehicle crashes are a leading cause of death for youth. Appropriate occupant protection significantly reduces these preventable injuries. Secondary field observation survey records were studied to identify populations that would most likely benefit from youth occupant protection programs. Multivariate regression analysis showed that drivers of youth between 4 and 14 years were in need of programs promoting youth and driver occupant restraint use. When these drivers were using seat belts, it was 35 times more likely they had youth occupants in safety restraints. A focus on pickup truck drivers may also give these programs greater efficacy in increasing youth restraint use. This study was limited to a single state, but the approach should be transferable to other jurisdictions where youth occupant protection field observation studies are conducted.

Abstract
BACKGROUND With long-standing and widespread high rates of errors in child restraint use, there is a need to identify effective methods to address this problem. Information supplied with products at the point of sale may be a potentially efficient delivery point for such a countermeasure. The aim of this study is to establish whether product materials developed using a consumer-driven approach reduce errors in restraint use among purchasers of new child restraint systems. METHODS A cluster randomised controlled trial (cRCT) will be conducted. Retail stores (n=22) in the greater Sydney area will be randomised into intervention sites (n=11) and control sites (n=11), stratified by geographical and socioeconomic indicators. Participants (n=836) will enter the study on purchase of a restraint. Outcome measures are errors in installation of the restraint as observed by a trained researcher during a 6-month follow-up home assessment, and adjustment checks made by the parent when the child is placed into the restraint (observed using naturalistic methods). Process evaluation measures will also be collected during the home visit. An intention-to-treat approach will be used for all analyses. Correct use and adjustment checks made by the parent will be compared between control and intervention groups using a logistic regression model. The number of installation errors between groups will be compared using Poisson regression. DISCUSSION This cRCT will determine the effectiveness of targeted, consumer-driven information on actual error rates in use of restraints. More broadly, it may provide a best practice model for developing safety product information. TRIAL REGISTRATION NUMBER ACTRN12617001252303p; Pre-results.

Abstract
Belt-positioning booster seat use (BPB) is an effective technology to prevent severe child injury in cases of car crash. However, in many countries, age-appropriate car restraint use for children aged 4-7 years old remains the lowest among all age groups. The aim of this study was to identify the main determinants of BPB use through a comprehensive approach. An ecological model was used to analyze individual, parent-child relationships, and neighborhood characteristics. Parents of children enrolled in the first and second grades completed a self-reported questionnaire (n=745). The data were subjected to multilevel modeling. The first level examined individual and parent-child relationship variables; in addition the second level tested between neighborhood variance. According to parental self- reports, 56.6% of their children had used a BPB on each car trip during the previous month. The results indicated that the determinants positively related to BPB use were individual and parental; namely, the number of children in the family, the parents' car seat belt use, parental knowledge of children's car safety principles, and a highly authoritative parenting style. Children's temperaments and parental supervision were not associated with BPB use. At the neighborhood level, a small difference was found between neighborhoods for BPB users compared to non-users.

Abstract
We explored the factors influencing the use of age-appropriate car seats in a community with a high proportion of Aboriginal families in regional New South Wales. We conducted a survey and three focus groups with parents of children aged 3–5 years enrolled at three early learning centres on the Australian south-east coast. Survey data were triangulated with qualitative data from focus groups and analysed using the PRECEDE-PROCEED conceptual framework. Of the 133 eligible families, 97 (73%) parents completed the survey including 31% of parents who reported their children were Aboriginal. Use of age-appropriate car seats was reported by 80 (83%) of the participants, and awareness of the child car seat legislation was high (91/97, 94%). Children aged 2–3 years were less likely reported to be restrained in an age-appropriate car seat than were older children aged 4–5 years (60% versus 95%: χ2 = 19.14, p < 0.001). Focus group participants highlighted how important their child’s safety was to them, spoke of the influence grandparents had on their use of child car seats and voiced mixed views on the value of authorised child car seat fitters. Future programs should include access to affordable car seats and target community members as well as parents with clear, consistent messages highlighting the safety benefits of using age-appropriate car seats.

Abstract
Booster seat use for 4-9 year olds remains the lowest of all age groups in many countries. The objective of this study is to examine whether parents' decision-making patterns, as measured by the Melbourne Decision Making Questionnaire, relate to car booster seat use. Israeli parents of 4-7 years old children (n = 398) answered a questionnaire about car safety and decision-making habits. Ninety per cent of parents reported having a booster seat; 70.5% reported consistent booster seat use in general and on short drives during the last month (booster seat use compliance index). Greater compliance index was positively related to a vigilant decision-making pattern, passenger compliance with rear seat belts and families with fewer children. Lower booster seat use compliance index was associated with buck-passing decision-making pattern. Health professionals and policy-makers should take into account parents' habitual decision-making patterns when designing interventions for car booster seat compliance.

Abstract
OBJECTIVE Suboptimal child restraint use includes incorrect and/or inappropriate restraint use and increases the risk of injury. Comfort has been suggested as an important factor impacting on optimal use of restraints by children. This article aims to examine the relationships between parent reported comfort and restraint misuse and age-appropriate restraint choice. METHODS This is an analysis of data from a cross sectional observation study of child restraint use in New South Wales. Logistic regression was used to model the relationship between parent-reported comfort and restraint misuse and age-appropriate restraint choice. RESULTS There was no significant relationship between either parent-reported comfort and restraint misuse or parent-reported comfort and age-appropriate restraint choice. CONCLUSIONS Parent perceptions of comfort of children in child restraints do not appear to be associated with incorrect child restraint use or age appropriate restraint choice. It is possible that the actual comfort of the child may be related to incorrect use but this remains to be tested. Further investigation of the relationship between parent-perceived comfort and the actual comfort of the child, as well as the impact of child comfort on optimal child restraint use is warranted.

Abstract
This study examined how child restraint system (CRS) features contribute to CRS installation errors. Sixteen convertible CRS, selected to include a wide range of features, were used in volunteer testing with 32 subjects. Subjects were recruited based on their education level (high or low) and experience with installing CRS (none or experienced). Each subject was asked to perform four child restraint installations in the right-rear passenger seat of a 2006 Pontiac G6 sedan using a crash dummy as a child surrogate. Each subject installed two CRS forward-facing (FF), one with LATCH and one with the vehicle seatbelt, and two CRS rear-facing (RF), one with LATCH and one with the seatbelt. After each installation, the experimenter evaluated 42 factors for each installation, such as choice of belt routing path, tightness of installation, and harness snugness. Analyses used linear mixed models to identify CRS installation outcomes associated with CRS features. LATCH connector type, LATCH strap adjustor type, and the presence of belt lockoffs were associated with the tightness of the CRS installation. The type of harness shoulder height adjuster was associated with the rate of achieving a snug harness. Correct tether use was associated with the tether storage method. In general, subject assessments of the ease-of-use of CRS features were not highly correlated with the quality of their installation, suggesting a need for feedback with incorrect installations. The data from this study provide quantitative assessments of some CRS features that were associated with reductions in CRS installation errors. These results provide child restraint designers with design guidelines for developing easier-to-use products. Research on providing effective feedback during the child restraint installation process is recommended.

Abstract
Child restraints protect a young child against injury in crashes but best practice child restraint use is low in Australia, particularly among lower socio-economic groups. We investigated factors associated with restraint use to inform the development of education and distribution programmes to support new Australian legislation on child passengers among families in low socio-economic areas of metropolitan Sydney. We interviewed a parent or carer of 1160 children aged 2-5 years enrolled at one of 28 early childhood centres in low socio-economic areas of urban Sydney. Appropriate child restraint use was defined as a forward facing child restraint (FFCR) for 2-3 year olds and a FFCR or booster seat for children aged 4 years or more. Predictors of self-reported appropriate use were explored using logistic regression. Analysis was conducted on one child from each family in the target age range (2-5 years): 586 (51%) were male and the mean age was 3.5 (Standard Deviation 0.8) years. There were 432 (45%) families with annual income below $60,000, 248 (22%) spoke a language other than English at home and 360 (33%) had 3 or more children. Fifty-four percent of carers indicated that their 2-3 year old children travelled in a FFCR. Inappropriate use among children in this age group was more likely when the carer was <36 years (odds ratio (OR) 1.62, 95% confidence interval (CI) 1.08-2.45), in families with ≥3 children (OR 1.64, 95% CI 1.10-2.44) and when the carer believed that a booster seat was just as safe as a FFCR (OR 2.98, 2.05-4.32). Eight-eight percent of carers of 4-5 year olds reported use of a booster seat or FFCR. Non-use was associated with low household income (OR 3.10, 95% CI 1.67-5.75), in families with ≥3 children (OR 2.03, 95% CI 1.09-3.76) and families where a language other than English is spoken at home (OR 2.39, 95% CI 1.10-5.21). Non-English speaking families had less awareness of the new law and poorer knowledge of safety benefits of child restraints. They also had lower household incomes and more concerns about cost of child restraints and booster seats. These findings can inform development of interventions to promote best practice child restraint use, which will reach non-English speaking families in this region. They also confirm the importance of economic and logistic barriers to best practice child restraint use.

Abstract
Paediatric trauma centres seek to optimise the care of injured children. Trends in state-wide paediatric care and outcomes have not been examined in detail in Australia. This study examines temporal trends in paediatric trauma outcomes and factors influencing survival and length of stay. A retrospective review was conducted using data from the NSW Trauma Registry during 2003-2008 for children aged 15 years and younger who were severely injured (injury severity score >15). To examine trauma outcomes descriptive statistics and multivariable logistic and linear regression were conducted. There were 1138 children severely injured. Two-thirds were male. Road trauma and falls were the most common injury mechanisms and over one-third of incidents occurred in the home. Forty-eight percent of violence-related injuries were experienced by infants aged less than 1 year. For the majority of children definitive care was provided at a paediatric trauma centre, but less than one-third of children were taken directly to a paediatric trauma centre post-injury. Children who received definitive treatment at a paediatric trauma centre had between 3 and 6 times higher odds of having a survival advantage than if treated at an adult trauma centre. The number of severe injury presentations to the 14 major trauma centres in NSW remains constant. It is possible that injury prevention measures are having a limited effect on severe injury in NSW. This research provides stimulus for change in the provision and co-ordination in the delivery of trauma care for injured children.

Abstract
OBJECTIVE The current study aimed to investigate the incidence of child restraint system (CRS) misuse and/or inappropriate use of CRS through an Australian CRS inspection program conducted by CRS fitting specialists between October 2004 and October 2011 and to determine whether CRS misuse and/or inappropriate use of CRS changed following new Australian legislation regarding CRS and motor vehicle restraint use for children aged 7 years and under. METHODS Participants were recruited through an advertisement for free CRS inspections displayed at childcare centers, kindergartens, community centers, hospitals, and child expos. At each inspection, a CRS fitting specialist inspected each child in their CRS while in their vehicle and reported to the owner of the CRS on the installation of the child restraint(s) and/or system(s) and any fitting faults and/or concerns with the fitting and/or use of the child restraint(s) and or system(s). RESULTS Results are based on the inspection of 2674 CRS. Of all of the CRS inspected, the majority (79%) were reported as having at least one instance of misuse and/or inappropriate use. The most common forms of CRS misuse and/or inappropriate use observed were harness strap errors (twisted, poorly adjusted, and/or incorrectly positioned, 41%), seat belt errors (incorrectly routed, twisted, and/or incorrectly adjusted, 32%), and a missing or incorrect fitting of the gated buckle/locking clip (24%). Significant differences were found across the proportion of CRS misuse and/or inappropriate use across restraint types (infant restraint/forward-facing CRS/convertible [birth to 18 kg] CRS/convertible [8-26 kg] CRS/boosters [booster seat/cushion/booster with harness combination]), χ(2)(4) = 147.852, P < .001. CRS misuse and/or inappropriate use were most prevalent among convertible CRS (birth to 18 kg; 87%), forward-facing CRS (85%), and convertible CRS (8-26 kg; 81%), compared to infant restraints (73%) and booster seats (booster seats/cushions/boosters with H-harness combination; 65%). There was no significant difference in the proportion of CRS with misuse and/or inappropriate use across the pre- and post-legislation period (80% vs. 77%), χ(2)(1) = 1.545, P > .5. CONCLUSIONS Based on the findings of the current study, it was concluded that, despite the introduction of new, definitive CRS legislation, CRS misuse and/or inappropriate use remains widespread in Australia. The findings highlight the need for CRS education and legislation that include information on correct CRS use, as well as information on appropriate CRS use, in order to provide specialized protection for child vehicle occupants in the event of a motor vehicle crash.

Abstract
OBJECTIVES We evaluated an education, distribution, and fitting program for increasing age-appropriate and correct child restraint use. METHODS We performed a cluster randomized trial involving 28 early childhood education centers in low socioeconomic status areas in Sydney, Australia. The main outcome was optimal restraint use defined as age-appropriate restraints, installed into the vehicle correctly and used correctly. RESULTS One service withdrew after randomization, so data are presented for 689 child passengers, aged 3 to 5 years, from 27 centers. More children attending intervention centers were optimally restrained (43% vs 31%; P = .01; allowing for clustering). More 3-year-olds were using forward-facing seats rather than booster seats, more 4- to 5-year-olds were using booster seats instead of seat belts alone, and there were fewer errors in use at intervention centers. Among non-English-speaking families, more children attending intervention centers were optimally restrained (43% vs 17%; P = .002; allowing for clustering). CONCLUSIONS The program increased use of age-appropriate restraints and correct use of restraints, which translates to improved crash injury protection. Multifaceted education, seat distribution, and fitting enhanced legislation effects, and the effect size was larger in non-English-speaking families.

Abstract
Most parents remember the first time they drove with a newborn child in the car. Feeling the need to protect the infant, they avoided sharp turns and drove more slowly and carefully than normal. But how long do these behaviors persist? Do parents ultimately revert to their previous driving patterns, or does some of the early protectiveness and caution continue to characterize their driving as their infant grows into a toddler and preschooler? In an attempt to answer these questions, two studies were conducted on parents of young children: a qualitative study consisting of personal interviews (16 parents); and a quantitative study in the form of a national telephone survey (165 parents). The results show that the most dominant reported effect of the transition to parenthood on driving is increased apprehension of traffic crashes and a stronger sense of responsibility. However, these changes were found to influence the reported actual driving behavior of only a portion of the parents. Possible explanations of the findings are discussed.

Abstract
This study evaluated the effectiveness of the NSW Restraint Fitting Station Network in preventing incorrect use of rearward facing and forward facing child restraints. The way children used restraints was observed randomly as they arrived at observation sites during a cross-sectional ecological study across New South Wales, Australia. Trained researchers examined restraint system installation once the child left the vehicle. A structured interview was also conducted with the driver. Logistic regression was used to examine the association between parental report of ever having the restraint checked at a Restraint Fitting Station and whether or not the restraint was used correctly, while controlling for potential confounders and accounting for the complex sample design. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated. The results demonstrated that children of respondents who did not use Restraint Fitting Stations were 1.8 times more likely to be incorrectly using their restraints (95% CI 1.1-2.8) than children of Restraint Fitting Station users. Regardless of whether or not a Restraint Fitting Station had been used, there was a trend towards a greater likelihood of incorrect restraint use as the length of restraint ownership increased (OR 1.3 95% CI 1.0-1.7). These results are important for developing strategies aimed at reducing child occupant casualties by reducing the rate of incorrect restraint use, and support programs encouraging the use of Restraint Fitting Stations and similar services as a countermeasure to incorrect use.

Abstract
BACKGROUND Road traffic crashes for car occupants are a leading cause of death and serious injury in children from high and middle income countries globally. Correct use of appropriate child restraints can significantly reduce death and serious injury but there is a need for well powered trials to examine effectiveness of programs to increase optimal child restraint practices. The aim of this trial is to examine the effectiveness of a comprehensive intervention to increase the use of appropriate child restraints, and decrease incorrect use of child restraints in pre-school aged children traveling in cars. METHODS AND DESIGN A cluster randomised controlled trial will be conducted, involving 28 pre-school or childcare centres in low income areas of Sydney, Australia, over one calendar year. The intervention is an educational program involving an in-service for centre staff, distribution of educational materials to parents, a parent workshop demonstrating restraint use, subsidised restraints for parents in need, and vouchers for a free restraint checking service. Blinded assessors will observe restraint use at all centres at the end of the calendar year. Data will be analysed on an intention-to-treat basis; the primary analysis will compare the proportion of each of the two outcome measures (use of appropriate restraints, and incorrect use of restraints) at each centre between intervention and control groups. Detailed process evaluation will be conducted, including examination of implementation and utilisation of various elements of the program by both centres and families. DISCUSSION This assessor blinded cluster randomised trial is powered to provide credible evidence about the efficacy of an education and distribution program in a pre-school setting to increase appropriate use, and decrease incorrect use of child restraints.
