Do you agree with Miss curvy?

Probably full of statistical anomalies, fat people are more likely to have heart attacks and given the number of people who survive heart attacks anyway there might be 100 fat people a day have a heart attack, and 50 survive.

 

Then you might have 10 healthy people have a heart attack and 8 of them survive, and the figures will still say that more fat people survived their heart attacks.

 

So reading a stupid study with no context or knowledge in the field is pointless - which is why people trust doctors to get it right, and doctors, NHS, UK Government use BMI as an indicator of health in people they judge it to be useful for.

 

You can fantasise as much as you like, but the obesity paradox is a well established medical phenomenon.

[Nagel]

In a regression model that controlled for age, gender, lifestyle variables (smoking, alcohol drinking and physical activity) and chronic co-morbidities, underweight (defined as BMI < 21 kg/m2) is associated with an increase in all-cause mortality in both men and women. Overweight–obesity (>27 kg/m2) is not associated with a significant change in all-cause mortality in all age ranges examined. Thus, the over-all relationship between body weight status and all-cause mortality risk (this is a load of toss) is L-shaped in Taiwanese over 53 years of age. This finding is similar to that observed in other Eastern populations such as the Japanese (Tamagotchi et al., 2009), Chinese in Hong Kong (Fuk Yoo et al., 2010) and the Koreans (Kim Jong-un et al., 2013).

 

What does this mean?

 

What is a Regression Model pls?

 

What does it mean if something is L-shaped in Taiwanese??? :confused:

Yet doctors still use it, it's still an indicator used on NHS and official Government media.

 

Someone needs to call them because there seem to be so many experts on SF who could clearly teach doctors better practice.

 

Don't confuse what the government and management tell the NHS to do with what most Drs would understand to be best practice.

I'm not an idiot I know if you're fit and healthy with muscle you'll have a high BMI, but fit and healthy people are not going to the doctors needing their BMI looked at - fat and lazy people are. And those are the ones BMI is useful for.

 

Fat lazy people don't need their BMI looking at, you've already identified that they are both overweight and doing too little exercise.

Your main argument seems to be to keep referring to what Drs think, did you bother to actually investigate?

They don't like it. Certainly not universally, and not after they've actually thought about what it measures.
