Head injury trends and helmet use in skiers and snowboarders in Western Canada, 2008-2009 to 2012-2013: an ecological study.

This research explored associations between helmet use and head injuries in snowsports by investigating reported snowsport injuries in Western Canada from 2008-2009 to 2012-2013. The key finding was that increased helmet use (from 69% to 80%) was not associated with a reduction in reported head injuries. Over the study period, the average rate of reported head injuries was 0.2/1000 skier visits, with a statistically significant variation ( P < 0.001). The line of best fit showed an non-significant upward trend ( P = 0.13). Lacerations were the only subcategory of head injuries that decreased significantly with helmet use. A higher proportion of people who reported a head injury were wearing a helmet than for injuries other than to the head. Skiers were more likely to report a head injury when wearing a helmet than snowboarders ( P < 0.001 cf. P = 0.22). There were significant differences in characteristics of helmet and non-helmet wearers. Helmet wearers were more likely to be: young adults ( P < 0.001); beginner/novices ( P = 0.004); and snowboarders ( P < 0.001), but helmet wearing was not associated with gender ( P = 0.191). Further research is needed to explore the possible reasons for the failure of helmets to reduce head injuries, for example, increased reporting of head injuries and increased risk-taking combined with over-rating of the helmets' protection.
