Objective-To apply a measure of exposure to injury risk for schoolchil
dren aged 11-14 across a population and to examine how risk factors va
ry with sex, age, and affluence. Design-Self completion questionnaire
survey administered in schools in May 1990. Setting-24 schools in Newc
astle upon Tyne. Subjects-5334 pupils aged 11-14, of whom 4637 (87%) c
ompleted the questionnaire. Results-Boys were exposed to greater risk
than girls in journeys to places to play outdoors: they took longer tr
ips and were more likely to ride bicycles (relative risk 5.30 (95% con
fidence interval 4.23 to 6.64)) and less likely to travel by public tr
ansport or car. Younger pupils (aged 11-12) were less exposed to traff
ic during journeys to and from school: their journeys were shorter, th
ey were less likely to walk (trip to school, relative risk 0.88 (0.83
to 0.94)), and they were more likely to travel by car (trip to school,
relative risk 1.33 (1.13 to 1.56)) or school bus (1.33 (1.10 to 1.62)
). Poorer children were exposed to greater risk than affluent children
(from families that owned a car and a telephone): they were less like
ly to travel to school by car (relative risk 0.26 (0.20 to 0.33)) or t
o be accompanied by an adult (0.39 (0.32 to 0.48)). Conclusion-Injury
risk data can provide useful information on child injury prevention an
d can be used to identify priorities and target resources for injury p
revention on a citywide scale or for an individual school.
