BMI index


solbjerg

Recommended Posts

The so called BMI (Body Mass Index) rests on a work done by a Frenchman in the 1800. He used data from the records of conscripted soldiers in the army. Most French at the time (average height) were about the height of Napoleon (163 cm), and those that were much higher were usually gangly. I.e pycnics and leptosomes.

This led to that the use of weight divided by the square power of the height in meters showed an acceptable correlation in the collected data.

Even though that it is self evident that when a person is twice the height, the width and the depth is correspondingly greater too, which suggest that the third power of the height in meters would have been better to use.

In 1972 an article appeared in America about this study. The insurance companies were looking for a scientific explanation on weight and health and longevity, and therefore readily adopted this study and the method of arriving at the numbers relating the weight ratio.

But due to the fundamental flaw created by the use of power to the second degree it will show tall people as fat even though they are quite normal.

In Denmark the BMI index is called the Fy&Bi index (Fy and Bi stands for Fyrtårnet and Bivognen - Lighthouse and Tender), it was a Danish comic-pair that made a number of

movies many years ago.

Long & Short (England), Ole & Axel (USA), Pat und Patachon (Germany), (Lighthouse & Tender - Fy&Bi (Denmark))

Most people can't square their height without the use of a calculator, so the reason for using the second power only is strange, as the third power is more correct scientifically. and just as easy to calculate with a pocket calculator. In the seventies these calculators became very common and rather inexpensive.

The BMI became official in the US in 1998, and most of the rest of the world followed suit after that [TABLE=border: 0, cellpadding: 0, cellspacing: 0]

hi

Actually it is more a comment on the validity of the current Body Mass Index.

The old one where you took your height in cm above 100 cm, and the subtracted 5 kg if you had a sleight stature or added 5 kg if you had a more massive stature, was more true for many people.

Always supposing that the height in general was between 150 cm and 200 cm or so

It feels as if the power of the height elevates it into a more "scientific" way, - which is rubbish.

Longevity-wise it seems to be a fact that sleight overweight is better, - provided that you are in a fair physical shape.

Today the height of the French population is around the medium height of people. When the study was made they were smaller by a couple of inches.

p.s. we are now over 7 billion (American notation) people in the world.

p.s. Twiggy had a BMI under 15, she was 42 kg and 1,68 m - for awhile she was the idol of the age -sorry to say

I wonder if doctors' software have something for calculating BMI. I think I'm a little overweight but my doctor doesn't saying anything about it during check ups. Should I be asking for my BMI or is it information that a doctor should voluntarily offer?
