【bio-news】预测一下你的寿命

Good genes may increase your odds of a long life. But if you really want to live to 90, you should cut down on the cheesy nachos and beer, turn off the remote and get out and exercise more often.
That's the clear implication of a study that followed 5,820 Japanese-American men for nearly 40 years to determine how well lifestyle factors in middle age can predict healthy aging. It found that middle-aged men who avoided risk factors such as obesity, heavy drinking and high blood sugar or hypertension were more than five times more likely to be alive and healthy at age 85 than those who didn’t.
Researchers at the Pacific Health Research Institute in Hawaii started following the men way back in the mid-1960s, when they were an average age of 54. All the men were healthy and free of major disease when they started the study.
Last year, the Hawaii researchers looked back to determine whether there were risk factors at age 54 that predicted how long any otherwise healthy person was likely to live. They found several including obesity, heavy drinking (three or more drinks a day), smoking, high blood sugar, high blood pressure and high levels of fatty particles in the blood called triglycerides.
Men with six or more risk factors at age 54 had only a paltry 22% shot of still being alive at age 85, and a downright pitiful 6% chance of making it to age 90 outside of a coffin. The few high-risk men who made it to 85 were generally in poor health.
But men without any risk factors at age 54 had a 69% shot at still being alive at age 85. The large majority of those men were free of any major diseases or disability at that age.
"I was blown away by the results," says Bradley Willcox, a geriatrician at the Pacific Health Research Institute in Honolulu who led the study. "It’s a huge difference." The study is published in The Journal of the American Medical Association.
Besides smoking, the biggest single risk factor for an early demise was high blood sugar in middle age.
Some other parameters that predicted long life were more surprising: grip strength in middle age correlated with long life, hinting at the importance of being physically robust in late middle age. (If you are not genetically endowed with big muscles, strength training during middle age could help on this front, Dr. Willcox suggests.) Married men also lived longer, although they were not healthier in old age. As other studies have found, men with more education were more likely to remain healthy in old age.
The next step for the Hawaii researchers is to examine how diet and genetics influences lifespan. The Japanese-American men in the study generally ate a diet with more vegetables and fish than the typical American fare.
The Honolulu study began before the advent of many modern drugs, including cholesterol lowering drugs as such Vytorin from Merck (nyse: MRK - news - people ) and Schering-Plough (nyse: SGP - news - people ), Lipitor from Pfizer (nyse: PFE - news - people ) or Crestor from AstraZeneca (nyse: AZN - news - people ). With better medical treatment, today's middle-aged men can expect to live even longer, Dr. Willcox said.

1. “大块朵颐”应为“大快朵颐”。朵颐：鼓动腮颊，即大吃大嚼。痛痛快快地大吃一顿。
〖出处〗《周易·颐》：“观我朵颐”。
2. ”已婚“非”以婚“。 谢谢了 [标签:content1][标签:content2]
