60秒科学:Muscle-Mass-Beats-BMI-as-Longevity-Predictor

听力内容:

60秒科学节目(SSS)是科学美国人网站的一套广播栏目,英文名称:Scientific American – 60 Second Science,节目内容以科学报道为主,节目仅一分钟的时间,主要对当今的科学技术新发展作以简明、通俗的介绍,对于科学的发展如何影响人们的生活环境、健康状况及科学技术,提供了大量简明易懂的阐释。

Doctors routinely measure a patient’s body mass index, or BMI. And if that weight-to-height ratio points to obesity, the doc might prescribe exercise, to shed the extra pounds. But when it comes to longevity, a focus on weight loss may be misplaced. Because BMI isn’t actually a very reliable indicator of life span. A more useful measure, some physicians say, might be muscle mass.

Researchers analyzed BMI and muscle mass data from more than 3,600 seniors in a long-term study. And they tracked which seniors had died, a decade later. Turns out BMI wasn’t much good at predicting chance of death.

But muscle mass was: more muscle meant better odds of survival. The study appears in The American Journal of Medicine.

There’s no cause-and-effect here just correlation for now. But study author Preethi Srikanthan, of U.C.L.A., has this recommendation: “Get up and start moving. Focus on trying to maintain the maximum amount of resistance training that you can, and stop worrying so much about dropping calories.” Which could take a little weight off your mind, too.
