Abstract

Objectives: With increased bicycle use during the COVID-19 pandemic and growing availability of bicycle-sharing programs in Montreal, we hypothesize helmet use has decreased. The aim of this study was to evaluate helmet use and proper fit among Montreal cyclists during the pandemic relative to historical data.

Methods: Nine observers collected data on bike type, gender, helmet use, and ethnicity using the iHelmet© app at 18 locations across the island of Montreal from June to September 2021. Proper helmet wear was assessed at one busy location. Multiple logistic regression was used to identify factors associated with helmet wear and results were compared to a historical study.

Results: Of the 2200 cyclists observed, 1109 (50.4%) wore a helmet. Males (OR = 0.78, 95%CI = 0.65-0.95), young adults (OR = 0.65, 95%CI = 0.51-0.84), visible minorities (OR = 0.38, 95%CI = 0.28-0.53), and bike-share users (OR = 0.21, 95%CI = 0.15-0.28) were less likely to be wearing a helmet, whereas children (OR = 3.92, 95%CI = 2.17-7.08) and cyclists using racing bicycles (OR = 3.84, 95%CI = 2.62-5.62) were more likely to be wearing a helmet. The majority (139/213; 65.3%) of assessed cyclists wore properly fitting helmets. Children had the lowest odds of having a properly fitted helmet (OR = 0.13, 95%CI = 0.04-0.41). Compared to 2011, helmet use during the pandemic increased significantly (1109/2200 (50.4%) vs. 2192/4789 (45.8%); p = 0.032).

Conclusion: Helmet use among Montreal cyclists was associated with age, gender, ethnicity, and type of bicycle. Children were least likely to have a properly fitted helmet. The recent increase in popularity of cycling and expansion of bicycle-sharing programs reinforce the need for bicycle helmet awareness initiatives, legislation, and funding prioritization.

RéSUMé: OBJECTIF: Avec la popularité grandissante du vélo durant la pandémie COVID-19 et l’expansion du vélopartage à Montréal, nous croyons que le port du casque a diminué. L’objectif de cette étude était d’évaluer l’utilisation du casque et le port adéquat parmi les cyclistes montréalais et de comparer nos résultats avec des données historiques. MéTHODE: Neuf observateurs, stationnés à 18 emplacements, ont recueilli les informations suivantes en utilisant l’application mobile iHelmet© : type de vélo, sexe, origine ethnique et port du casque. Le port adéquat du casque a été observé à un endroit. L’association de chaque variable avec le port et le port adéquat a été fait par régression multivariable et comparé à des données historiques. RéSULTATS: Des 2 200 cyclistes observés, 1 109 (50,4 %) portaient un casque. Les enfants (OR = 3,92, IC95% = 2,17–7,08) et les cyclistes de performance (OR = 3,84, IC95% = 2,62–5,62) portaient le casque plus fréquemment tandis que les hommes (OR = 0,78, IC95% = 0,65–0,95), les jeunes adultes (OR = 0,65, IC95% = 0,51–0,84), les minorités visibles (OR = 0,38, IC95% = 0,28–0,53), et les utilisateurs de vélopartage (OR = 0,21, IC95% = 0,15–0,28) le portaient moins. La majorité (139/213; 65,3 %) des casques étaient portés adéquatement. Les enfants étaient plus à risque de porter un casque mal ajusté (OR = 0,13, IC95% = 0,04–0,41). L’utilisation d’un casque chez les cyclistes montréalais a augmenté significativement depuis 2011 (1 109/2 200 (50,4 %) c. 2 192/4 789 (45,8 %); p = 0,032). CONCLUSION: Le port du casque à vélo à Montréal est associé à l’âge, le sexe, l’origine ethnique et le type de vélo. Les enfants sont plus à risque de mal porter un casque. Des stratégies de promotion ainsi que la législation peuvent favoriser des comportements sécuritaires à vélo.
