Is BMI a scam

Is BMI a scam?

BMI 是骗局吗?


There are few single measures in health care that seem to carry as much weight as body mass index, or BMI. Many feel judged by it, but after talking with an epidemiologist, two obesity medicine physicians, a health psychologist and a sociologist, none claimed that BMI was a very useful measure of a person's health. And, in fact, some said they would indeed call it a scam.

在医疗保健领域,几乎没有一项单一指标像身体质量指数(或者说 BMI)那样重要。很多人觉得这个指数对他们的身材妄加评论了,但是在和一名流行病学家、两名肥胖内科医生、一名健康心理学家以及一名社会学家交流后,他们中没有一个人说 BMI 是衡量人体健康的有效指标。而且事实上,有些人说他们的确会称其为骗局。

For all its utility as a research tool, body mass index is "fairly useless when looking at the individual," said an associate professor at the University of Ottawa.

渥太华大学的一名副教授说,尽管身体质量指数作为一种研究工具很有效,但“就个体而言,它相当无用。”

BMI can't tell, for instance, what percentage of a person's weight is from their fat, muscle or bone. Another problem with BMI is that it was developed and validated mostly in white men. But body composition and its relationship with health can vary depending on your gender, race and ethnicity.

例如,BMI 不能区分到底人体中有多少重量来自脂肪、肌肉或骨骼。另一个问题是,BMI 主要是从白人男性身上研究得出并验证的。但是,身体组成和它与健康的关系会因性别、种族和民族而有所不同。

It can be if it's used to set arbitrary goal posts for body size. An associate professor at the Weill Cornell Medical College said that some patients who have lost weight and reached what she sees as their "healthy, happy weight," but who still have a high BMI, may feel that they have to unnecessarily or unrealistically drop more pounds to be considered normal on the scale.***

如果用它来为体型设置任意的目标,它就会有害。威尔康奈尔医学院的一名副教授说,有些减肥后的患者已经达到了她认为“健康、快乐的体重”,但是他们的 BMI 仍然较高,就可能会觉得自己应该减掉更多才是正常的,但这其实是不必要也不切实际的。

It can also be harmful if a doctor assumes that a person with a normal body mass index is healthy, and doesn't probe them about potentially unhealthy habits they may have. And if the doctors of patients with higher BMIs focus on weight alone as the cause of any health issues they may have, the doctors may risk stigmatizing patients.

另外,如果医生想当然地认为身体质量指数正常的人就是健康的,却不调查他们潜在的不健康习惯,这也有可能有害。而且如果高 BMI 患者的医生只把体重作为他们可能存在健康问题的原因,就可能会有污名化患者的风险。
