To the Editor: Despite expert recommendation, Australian states have yet to enact legislation requiring use of child restraints beyond the age of 12 months.
Our analysis of police crash records and linked hospital separation data for the period July 2000 to June 2001 in New South Wales found that a large proportion of children who were hospitalised following motor vehicle accidents were reported by police as having used adult (standard) seatbelts at the time of injury (Box).
It is of particular concern that over 80% of 5–8-year-olds in this cohort were using standard seatbelts rather than child restraints (eg, booster seats). This pattern of premature “graduation” to seatbelts has also been reported in general populations of child motor vehicle passengers both overseas1 and in Australia,2 and also in presentations of child motor vehicle passengers after a crash to a NSW hospital’s emergency department.3
Child restraints are specifically designed to provide crash protection for children’s anthropometrical dimensions. Standard seatbelts are not designed to accommodate children, so they are unlikely to achieve the good fit to rigid body parts required for safety. Consequently, use of standard seatbelts by young children allows more head excursion during a crash, thereby negating their primary goal of protecting against central nervous system injury, and potentially causing Chance fractures and abdominal injuries.4 Our results provide further evidence that such seatbelt use may not protect, or may even cause injuries, during a crash.
Child road trauma is largely preventable or controllable with the use of appropriate child restraints, including booster seats. A cost–benefit analysis showed that the use of booster seats produced a benefit–cost ratio for road trauma prevention of 9.4 (US$1854/US$197).5 To prevent child road trauma in Australia, all child motor vehicle passengers should use appropriate child restraints.
Australian child road safety stakeholders recommend that child motor vehicle passengers use appropriate restraint systems according to their height, weight and age when travelling on road. Our findings provide further justification for proposed legislative changes that would require the compulsory use of appropriate child restraints for child motor vehicle passengers.
