Cross-country skiing is associated with reduction in risk of adverse vascular outcomes, but its association with type 2 diabetes is uncertain. We aimed to assess the associations between leisure-time cross-country skiing habits and incident type 2 diabetes.
We analysed the data of 2483 middle-aged men with no history of diabetes at baseline in the Kuopio Ischemic Heart Disease prospective study. The frequency, average duration, and intensity of leisure cross-country skiing were assessed at baseline using a 12-month physical activity questionnaire. Hazard ratios (HRs) (95% CIs) for type 2 diabetes were estimated.
During a median follow-up of 21.6 years, 539 men developed type 2 diabetes. Type 2 diabetes risk decreased with increasing total volume of cross-country skiing up to 1,215 metabolic equivalent task (MET) hours/year. In analyses adjusted for several established risk factors, when compared with men with no cross-country skiing activity, the HRs (95% CIs) for type 2 diabetes were 0.75 (0.62-0.92) and 0.59 (0.46-0.76) for men who did 1-200 and >200 MET hours/year of cross-country skiing, respectively. Compared with men with no cross-country skiing activity, the corresponding adjusted HRs (95% CIs) for type 2 diabetes were 0.73 (0.60-0.89) and 0.64 (0.50-0.82) for men who did 1-60 and >60 minutes/week of cross-country skiing, respectively. The associations remained consistent following further adjustment for prevalent comorbidities.
Total volume and duration of leisure-time cross-country skiing are each inversely and independently associated with future type 2 diabetes risk in a male population. Cross-country skiing undertaken as a leisure activity has the potential to promote public health.
越野滑雪与降低不良血管事件风险相关，但与 2 型糖尿病的关系尚不确定。本研究旨在评估休闲时间越野滑雪习惯与 2 型糖尿病发病之间的关系。
我们分析了库奥皮奥缺血性心脏病前瞻性研究中 2483 名基线时无糖尿病病史的中年男性的数据。使用 12 个月的体力活动问卷评估基线时的休闲越野滑雪频率、平均持续时间和强度。使用风险比（HR）（95%置信区间）估计 2 型糖尿病的发病风险。
在中位随访 21.6 年期间，539 名男性发生 2 型糖尿病。2 型糖尿病发病风险随越野滑雪总运动量的增加而降低，最高可达 1215 代谢当量（MET）小时/年。在调整了几个既定风险因素后，与没有越野滑雪活动的男性相比，从事 1-200MET 小时/年和>200MET 小时/年越野滑雪的男性发生 2 型糖尿病的 HR（95%CI）分别为 0.75（0.62-0.92）和 0.59（0.46-0.76）。与没有越野滑雪活动的男性相比，从事 1-60MET 小时/周和>60MET 小时/周越野滑雪的男性发生 2 型糖尿病的相应调整 HR（95%CI）分别为 0.73（0.60-0.89）和 0.64（0.50-0.82）。在进一步调整了已患合并症后，这些关联仍然一致。
在男性人群中，休闲时间越野滑雪的总运动量和持续时间与未来 2 型糖尿病发病风险呈负相关且独立相关。作为休闲活动的越野滑雪有促进公众健康的潜力。
