防早死 糖尿病病人应锻练
美国得克萨斯州的研究人员发现，血糖代谢紊乱的病人如果不锻练的话早死的可能性要比正常人高一倍，该研究发表在最近一期《内科学年鉴》上。医生一直向病人推荐锻练来控制血糖紊乱，该研究首次提供了令人信服的证据阐明锻练可以拯救糖尿病患者的生命。
美国达拉斯的库柏研究所的研究人员研究了锻练对1,200多位中年II型(或称之为成年期发病)糖尿病患者死亡率的影响。II型糖尿病是由于细胞对血糖代谢激素胰岛素不敏感而导致的，是一种最常见的糖尿病类型，估计全美约有1,500万人患病。经过平均12年的随访之后研究人员发现，心脏应急测试结果差的病人的死亡危险性是积极锻炼的人的两倍。不爱锻炼的病人的死亡风险性会高出70%，主要死因有心脏病、癌症、胃病以及糖尿病的各种并发症。在排除了糖尿病家族史、吸烟、超重等因素后，不爱锻炼对死亡率的影响结论不变。
库柏研究所科学家，该项研究的带头人魏明医生认为，规律性的运动可以降低II型糖尿病人的死亡率。这个“规律性”通常是指每周锻炼三次，每次30分钟。即使中等强度的锻炼，如快速步行，也能起到一定作用，既可以改善心脏功能，降低血糖，还可以增强机体对血脂的平衡作用。尽管这项研究仅在男性中进行，但魏明医生说女性患者也同样可以从运动中获益。

耶鲁大学糖尿病专家、美国糖尿病协会的当选主席罗伯特·舍温博士则认为，这项最新的研究传递了一个清晰的信息，那就是有规律地锻炼对糖尿病的治疗非常重要。因为医生都倾向于认为锻炼是一种保持体重及减肥的方式，但并不十分清楚它对人类寿命也有好处。舍温博士同时也指出，锻炼对各年龄层的糖尿病人都有好处，而不仅仅只针对老年人。近年来，青少年中II型糖尿病的发病率急剧上升，已经引起了医生们的密切重视。这一年龄组的情况与肥胖和少动也很有关系，但是16岁患糖尿病的后果和代价将比56岁患糖尿病要严重得多。
需要强调的是，如果你是II型糖尿病患者，千万不要未经医生检查就做大运动量的锻炼。因为许多糖尿病患者有严重的心血管疾病，并不合适做剧烈运动。不过，适度锻炼对任何人都不会有问题。
It‘s Official: Exercise Saves Diabetics‘ Lives

Confirming what has long been considered a cornerstone of diabetes treatment, Texas researchers say men with the blood sugar problem are twice as likely to die early if they don‘t exercise.
The study, which appears in the latest issue of the Annals of Internal Medicine, comes as no surprise to doctors, who have long recommended physical activity as a way to help diabetics rein in unruly blood glucose. But the findings are among the first to convincingly demonstrate that this approach indeed saves lives.

The researchers, from the Cooper Institute in Dallas, studied the effects of exercise on death rates in more than 1,200 middle-aged men with Type II, or adult-onset, diabetes. Type II diabetes, in which cells stop responding to the sugar processing hormone insulin, is the most common form of the condition, affecting an estimated 15 million Americans.
After an average of 12 years of follow-up, men who performed poorly on heart stress tests were roughly twice as likely to die during the study as those who said they were active, the researchers found. Those who were inactive had about 70 percent higher risk of premature death, particularly from heart trouble, cancer, gastric disease and complications from their diabetes.

The effect of sedentary living on mortality was almost as great when the researchers adjusted for various factors, including family history of diabetes, whether they smoked and if they weighed too much.
"Regular physical activity was associated with lower mortality in men with Type II diabetes," says Dr. Ming Wei, a Cooper Institute scientist and the study‘s lead author. "Regular" workouts usually mean 30 minutes a day at least three times a week.

Even modest exercise, like brisk walking, helps in a number of ways, says Wei. "It increases heart function, lowers blood glucose" and improves the body‘s balance of blood fats, he says.
Although his study was only conducted in men, Wei says women with diabetes should reap the same benefits from exercise.
Dr. Robert Sherwin, a Yale University diabetes specialist and president-elect of the American Diabetes Association, says the latest study "sends a much clearer message" about the importance of regular exercise in diabetes treatment.

"We as physicians tend to think of exercise as a way of maintaining weight and effecting weight reduction, and we don‘t think of it quite as clearly as having a benefit for life expectancy."
Sherwin also notes that exercise helps diabetics of all ages, not just older adults. Doctors have watched with alarm as the incidence of Type II diabetes among young children and teens has ballooned in recent years.
The condition among this group is also strongly linked to obesity and inactivity, says Sherwin, but the consequences and costs of getting diabetes at age 16 instead of 56 are much greater.

What To Do
If you have Type II diabetes, don‘t rush out to the gym for a sweat-soaked workout without first checking with your doctor, Sherwin warns. Many diabetics suffer from serious cardiovascular problems that could make sudden, intensive exercise a bad idea.
On the other hand, he says, moderate activity shouldn‘t be a problem for any patient, and, as the latest study shows, it can be lifesaving.
