滑雪爱好者患抑郁和痴呆的风险更低

隆德大学和乌普萨拉大学的研究员对1989年至2010年间参加瑞典越野滑雪比赛Vasaloppet的20万人进行了研究。与由普通人口构成的规模类似的对照组相比，他们发现：确诊为痴呆和抑郁症的滑雪患者的人数比对照组低50%。滑雪者患帕金森疾病（一种退行性神经系统疾病）的风险也相对更低。

Among two decades of Vasaloppet finishers, the researchers found that 233 people had developed dementia, compared to 319 cases of the disease among non-racers. In addition, 1,030 skiers were later diagnosed with depression, compared to 2,045 in the control group. The numbers for Parkinson's were less definitive, but the Vasaloppet skiers still fared better than average: Only 119 of them were diagnosed with the disease, versus 164 people in the general population. Any way you look at it, the skiers were clearly the ones with the reduced risk of disease.

在这20年间完成Vasaloppet比赛的滑雪者中，研究员发现233人患有痴呆症，而未比赛的对照组中，319人患有这一疾病。此外，1030名滑雪者在后来的时间内被诊断出抑郁症，而对照组的人数为2045名。患帕金森疾病的人数尚未确定，但Vasaloppet滑雪者的患病人数仍低于平均水平，只有119人，而对照组为164人。从任何一个角度而言，滑雪者患这些疾病的风险都显然更低。

Interestingly, researchers found that the risk of developing Alzheimer's disease, another major neurological disorder, was not reduced among the skiers. That actually contradicts previous studies in the field that suggest physical activity can lower the risk of Alzheimer's.
