PREVENTION OF BICYCLE-RELATED INJURIES: Helmets, Education, and Legislation

Annual Review of Public Health, Vol. 19:293-318 (Volume publication date May 1998) Frederick P. Rivara, Diane C. Thompson, Matthew Q. Patterson, and Robert S. Thompson.

Portion of the abstract: "Helmets have been shown to reduce bicycle-related head injuries for cyclists of all ages involved in all types of crashes including those with motor vehicles. Helmet use has been promoted using educational campaigns, helmet subsidies, and legislation. Careful evaluation of these strategies has shown that these interventions increase helmet use and decrease the incidence of bicycle injuries."

Helmet-use rates are for children except for
Victoria, Australia, which included adults.

Swedish Study

Swedish authorities published a paper in 2003 evaluating helmet campaign strategies. The overall conclusion is that a considerable increase in helmet use by cyclists could be achieved by noncompulsory measures, but the use levels are not as high as those achieved by legislation.

Dutch Study

A similar study in the Netherlands turned up some different conclusions about helmet use. We have the abstract and a link to the original study in Dutch.
