Objective: To describe the impact of a community bicycle helmet campaign on helmet use and the incidence of bicycle-related head injuries.
Setting: Metropolitan community and a large health maintenance organization.
Interventions: Communitywide bicycle helmet campaign.
Outcomes: Rate of observed bicycle helmet use in the community and incidence of bicycle-related injuries in an health maintenance organization population.
Results: Helmet use among school-aged children increased from 5.5% in 1987 to 40.2% in 1992. Bicycle-related head injuries decreased by 66.6% in 5- to 9-year-old and 67.6% in 10- to 14-year-old members of an health maintenance organization.
Conclusions: Educational campaigns can increase helmet use and decrease the incidence of bicycle-related head injury.
