Abstract
Bicycle-related injuries are a leading cause of child and youth hospitalizations in Canada. The use of helmets while bicycling reduces the risk of brain injuries. This study investigated the long-term effect of legislation coupled with enforcement to improve helmet use rates. We conducted a longitudinal observational study of helmet use at 9, 11, and 14years after bicycle helmet legislation was enacted. Data were compared to baseline observations collected after legislation was passed in 1997. A comprehensive enforcement and educational diversion program, Operation Headway-Noggin Knowledge (OP-NK), was developed and implemented in partnership with regional police during the study period. Helmet use was sustained throughout the post-legislation period, from 75.3% in the year legislation was enacted to 94.2% 14years post-legislation. The increase in helmet use was seen among all age groups and genders. Helmet legislation was not associated with changes in bicycle ridership over the study years. OP-NK was associated with improved enforcement efforts as evidenced by the number of tickets issued to noncompliant bicycle riders. This observational study spans a 16-year study period extending from pre-legislation to 14years post all-age bicycle helmet legislation. Our study results demonstrate that a comprehensive approach that couples education and awareness with ongoing enforcement of helmet legislation is associated with long-term sustained helmet use rates. The diversion program described herein is listed among best practices by the Public Health Agency of Canada.
