Time series analysis reveals decreased bicycle-related mortality in children following helmet legislation, suggesting mandatory helmet laws effectively reduce fatal injuries.

Key Points

To evaluate trends in bicycle-related mortality rates among pediatric and adult cyclists before and after the introduction of youth helmet legislation.
Analyzed 362 bicycle-related deaths in Ontario, Canada, spanning a 12-year period from 1991 to 2002.
Calculated pre- and post-legislation average annual deaths and mortality rates per 100,000 person-years across two cohorts: ages 1–15 and ≥16 years.
Conducted a time series analysis to model differences in monthly bicycling deaths before and after the October 1995 helmet law.
For cyclists aged 1 to 15 years (107 deaths), average deaths per year fell by 52% and mortality rate dropped by 55%, with time series analysis showing an estimated reduction of -0.59 deaths per month.
For cyclists aged ≥16 years (255 deaths), average annual deaths and mortality rates per 100,000 person-years showed only slight changes, with time series analysis showing no significant reduction after legislation.
