Removing barriers to booster seat use in Canada

The impact of child safety restraint legislation on child injuries in police-reported motor vehicle collisions in British Columbia: An interrupted time series analysis

BACKGROUND/OBJECTIVE

Motor vehicle collisions (MVCs) remain a leading cause of death and serious injury in Canadian children. In July 2008, British Columbia introduced child safety seat legislation that aimed to reduce the number of children killed or injured in MVCs. This legislation upgraded previous child seat legislation (introduced in 1985) and affected children zero to three and those four to eight years of age. The objective of the present study was to evaluate the effectiveness of this legislation.

METHODS

Deidentified police reports for all MVCs involving zero- to 14-year-olds (2000 to 2012) were used to compare injury rates, booster seat use, and seating position among children before and after booster seat laws. An interrupted time series design was used to estimate the effect of the new law on injuries among children zero to three and four to eight years of age. Estimates were adjusted using children nine to 14 years of age as controls.

RESULTS

The booster seat law was associated with a 10.8% (95% CI 2.7% to 18.9%) reduction in the monthly rate of injuries in four- to eight-year-old children (P=0.01). This was equivalent to a decrease of 14.3 injuries per 1,000,000 children. Similarly, the monthly injury rate among children zero to three years of age decreased by 13.0% (95% CI 1.5% to 24.6% [9.8 injuries per 1,000,000]; P=0.03).

CONCLUSION

The results provide evidence that British Columbia's new child safety restraint law was associated with fewer injuries among children covered by the new laws.

The spectrum of seat belt syndrome among Canadian children: Results of a two-year population surveillance study

BACKGROUND

Seat belts have been proven to save lives. However, if they are not properly fitted, 'seat belt syndrome' can occur. The aim of the present study was to describe injuries encountered in Canadian children with seat belt-associated injuries.

METHODS

Canadian paediatricians and paediatric subspecialists were surveyed monthly through the Canadian Paediatric Surveillance Program. Children younger than 18 years of age who were restrained in motor vehicles at the time of a collision, with abdominal or thoracolumbar spine injuries, were included. The children may have been restrained in child safety seats, booster seats, or two- or three-point seat belts.

RESULTS

Twenty-eight children, between two and 16 years of age, with injuries compatible with seat belt syndrome were reported in Canada between September 2003 and August 2005. Although 12 children were younger than eight years of age, only one was restrained in a booster seat and only four of the older children were properly restrained with a three-point seat belt. Twenty-four children had abdominal injuries. Of these, 18 had stomach and/or intestinal injuries and 11 had solid organ injuries. Twelve patients had a spinal fracture, including only five Chance-type fractures. Seven patients presented with paraplegia, and none of them recovered.

CONCLUSION

In Canada, over a two-year period, 28 children were reported to have sustained injuries consistent with seat belt syndrome; seven of these children remained paraplegic. These results emphasize the necessity to review restraints in motor vehicles to adequately protect children.

Children at risk: predictors of car safety seat misuse in Ontario

When used correctly, child safety seats can reduce the risk of death and serious injury by 54% in toddlers and 71% in infants [National Highway Traffic Safety Administration (NHTSA), 2001. Traffic Safety Facts 2001. Children (DOT HS 809 471), U.S. Department of Transportation, Washington, DC]. The purpose of this study was to identify factors that predict correct use of car safety seats. The study was conducted in a large urban area in Southwestern Ontario and a small urban and rural area in Northern Ontario. Participants were 1263 caregivers who completed a self-report survey on their knowledge and use of car safety seats for their children (N=2199). Logistic regression analysis revealed that female caregivers, caregivers with higher levels of education, and caregivers who reported that finding information about the correct use of child safety seats was "difficult" were more likely to report correctly using car safety seats. The results also showed that children aged 7 months to 8 years old had substantially lower odds of being in the correct car safety seat compared to children aged 6 months or younger, or children aged 9 years or older. The high risk nature of misuse of child seats for infants and younger children may be an important cue to action for health professionals to develop comprehensive prevention strategies.

The effectiveness of a multimedia intervention on parents' knowledge and use of vehicle safety systems for children

Trauma due to road crashes is the leading cause of death and injury in Canadian children younger than 14 years, despite mandatory use of vehicle restraints since 1977. A multisite intervention study using a pretest-posttest design was conducted in four Ontario cities to test the effectiveness of an educational program on parents' knowledge of safety system use for children (0-12 years) 6 weeks following the educational intervention. The sample consisted of 418 families who reported on 732 children. Results indicated that knowledge increased significantly following the intervention. Use of professional sources of information was an important factor that is linked with increased parents' knowledge.

Evaluation of Safe Kids Week 2004: age 4 to 9? It's booster seat time!

OBJECTIVE

To assess the effectiveness of a national one week media campaign promoting booster seat use.

DESIGN

Pre-test, post-test design based on nationally representative random digit dialing telephone survey, with control for exposure to campaign.

SETTING

Canada.

SUBJECTS

Parents of children aged 4-9 years.

INTERVENTIONS

During a one week campaign in May 2004, information on booster seat use was distributed via a national media campaign, retail stores, medical clinics, and community events. Information included pamphlets with guidelines for booster seat use, as well as a growth chart (designed by Safe Kids Canada) to assist parents in determining if their child should be using a booster seat. Assessing seat belt fit was described in detail on the growth chart.

MAIN OUTCOME MEASURES

Knowledge, attitudes, and self-reported behaviors regarding booster seat use.

RESULTS

Respondents in the group exposed to the campaign were twice as likely to report using a booster seat with lap and shoulder belt for their child (47%), compared to those in the pre-test (24%) and the unexposed (23%) groups (p<0.001). However, only small differences in general knowledge regarding booster seat use were found between the groups.

CONCLUSIONS

A one week national media campaign substantially increased self-reported use of booster seats. Parents did not remember details of the campaign content, but did remember implications for their own child.
