BACKGROUND The effectiveness of bicycle safety helmets in preventing head injuries is well- documented. Recent studies differ regarding the effectiveness of bicycle helmets in preventing facial injuries, especially those of the mid-face and the mandible. OBJECTIVES The present study was conducted to determine the protective effect of a bicycle helmet in preventing mid-face and mandibular frac...

OBJECTIVES This study analyzed the reduction in risk of head injuries associated with use of bicycle helmets among persons ages 3 to 70 and the cost-effectiveness of helmet use based on this estimated risk reduction. METHODS To derive our cost-effectiveness estimates, we combined injury incidence data gathered through a detailed and comprehensive injury registration system in Norway, acute me...

OBJECTIVE Childhood bicycle-related head injuries can be prevented through the use of helmets. Although helmet legislation has proved to be a successful strategy for the adoption of helmets, its effect on the rates of head injury is uncertain. In Canada, 4 provinces have such legislation. The objective of this study was to measure the impact of helmet legislation on bicycle-related head injurie...

Systematic reviews of bicycle helmet research T he recently published systematic review of the effectiveness of bicycle helmet legislation brings to a total of three published reviews on this topic in the Cochrane Database of Systematic Reviews: 1. Helmets for preventing head and facial injuries in bicyclists; 2. Non-legislative interventions for the promotion of cycle helmet wearing by childre...

OBJECTIVE This study analyzes the population attributable fraction (PAF) of bicycle head injuries due to non-helmet use. METHODS The concept of the PAF and Levin's formula for its calculation were used to develop mathematical models for estimation of: (i) attributable fraction of bicycle related head injuries in the population due to non-helmet use, (ii) expected proportion of helmeted cases ...

This article seeks to answer the question whether mandatory bicycle helmet laws deliver a net societal health benefit. The question is addressed using a simple model. The model recognizes a single health benefit--reduced head injuries--and a single health cost-increased morbidity due to foregone exercise from reduced cycling. Using estimates suggested in the literature on the effectiveness of h...

OBJECTIVE The purpose of this study was to describe bicycle helmet use among Montreal cyclists as a step towards injury prevention programming. METHODS Using a cross-sectional study design, cyclists were observed during 60-minute periods at 22 locations on the island of Montreal. There were 1-3 observation periods per location. Observations took place between August 16 and October 31, 2011. S...
