Rise In Serious Head Injuries Among Snowboarders And Skiers

ScienceDaily (Dec. 10, 2007) ― Serious head injuries among alpine skiers and snowboarders have risen over the past 15 years, reveals research in Injury Prevention.

The increase has coincided with faster speed and the inclusion of more jumping and acrobatics as the norm in these sports, say the authors.

The authors base their findings on a comprehensive international trawl of published research on injuries sustained by mountain skiers and snowboarders between 1990 and the end of 2004.

They looked particularly for serious brain and spinal cord injuries. These make up a relatively small proportion of those sustained while skiing and snowboarding, but they are the leading cause of death, say the authors. A cache of 51 articles revealed 24 from 10 countries that were relevant.

The research suggests that the rate of this type of serious injury has steadily risen in all the countries that have reported data.

One study indicates that the percentage of head injuries among skiers has increased from 12% in 1993 to 15% in 1997, while the number among snowboarders has quintupled over the same timeframe.

Another piece of research suggests that skiers and snowboarders under the age of 35 are more than three times as likely to have a brain injury as younger participants. And several studies suggest that male sporting enthusiasts are significantly more likely to be seriously injured than their female peers.

The research points to a similar picture for spinal cord injuries, including the gender imbalance. The research also shows that the wearing of helmets can cut the risk of serious brain injuries by between 22% and 60%.

The authors warn that these injuries are usually devastating and irreversible, and immensely costly. More needs to be done to promote the wearing of helmets and the enforcement of design standards for them, they add.

滑雪爱好者严重卢脑损伤增加
科学日报载：据损伤防护的研究显示，在过去的15年中，高山滑雪者和滑板滑雪者不断发生严重卢脑损伤。
作者说，滑雪速度越快，跳跃越多，特技动作越多，受伤的可能性越大。这些研究基于对1990－2004年的国际上公布的因高山滑雪而遭受外伤的人群的大规模拉网式调查。
作者表示，他们关注的主要是严重脑损伤和脊柱损伤，虽然这类受伤者占滑雪总人数比例相对很小，但是这些损伤后果严重，导致死亡。他们收集到的10个国家的51篇文章中有24篇与之相关。
研究显示，所有有数字报道的国家，滑雪导致的严重损伤发生率一直在持续上升。其中一项研究表明，从1993年到1997年，滑雪者脑损伤所占百分比由12％上升到15％，然而在同样的时间段中，滑板滑雪者的损伤比例增加是前者的五倍之多。另一研究表明，年龄在35岁以下的滑雪者发生脑损伤可能性，是参加其他运动年轻人的三倍。另外，几项研究结果显示，男性滑雪运动爱好者比女性更易发生严重损伤。
研究发现脊髓损伤和卢脑损伤情况是相似的，也有与性别的相关的不均横现象。研究还表明，佩戴头盔可以将卢脑损伤发生率减少22％－60％。
作者强调，这些损伤往往是极具破坏性，且不可恢复，治疗费用相当昂贵。为此非常有必要佩戴头盔，并且需要为滑雪者设计一套安全标准以避免损伤。
