Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.

Actually, small difference: 3%-7%, apparently. Which is a big cumulative difference when it's constant.

That's an interesting POV that I've not heard before.

A good portion of the food we eat is to keep us at operating temperature. When it's cold we need to burn a bit more. The 3%-7% claim is from military doctor talking about the affect of cold weather on outdoor activities: I wonder if that takes into account the affect on the metabolism of constantly having to burn faster to keep warm?

I heard recently that in cold climates poor children spend so much of their food intake keeping warm that they grow less, so there is a correlation between income and body size.

Then people in Sweden shouldn't be so tall...but they are.
I wonder if they are getting fat too? Cause they never had that problem before and having a high standard for decades the food was not something they missed...All tho they it much of the sea food which is much better...

Larger bodies retain more heat - heat production is proportional to body mass and heat loss proportional to skin surface. Volume to surface ratio favours large bodies in cold climates.

But you misunderstand my claim anyway. The claim is that among a ethnically homogeneous group of Swedes living in Sweden, those in relative poverty would grow to be shorter, on average, than wealthier ones.

I understand what you mean...in scientific sense...
But I am not so sure the theory is relevant in this sense.
Here where I live - tropical QLD, people are also getting fat...even Asians that are not genetically predisposed...so I am sure it's about food.

We are tall now, but used to be short when food was scarce. There was a class difference in height back then, but I think that was the case in most nations since poverty meant not always enough food during the three periods of growth spurt - in the womb, the first 2 years of living and puberty.

Weight is going up here too, but not dramatically so. There is a worrying fixation on weight though. Personally I suspect that obesity (not just a couple of extra kilos) is often linked with an unhealthy relation with food, where food becomes a substitute for something else. And if that something else is to look skinny you have got yourself a feedback loop.

A swedish kind of death: We are tall now, but used to be short when food was scarce.

According to Barbra Demick, 18-year old escapees from North Korea average five inches (13 cm) shorter than 18-year old South Koreans.

Demick also says that this adds insult to the injury of finding themselves at the bottom of society when North Korean refugees manage to make it to South Korea.  She says South Korea is a "heightist" society.  But which society isn't?

The march of civilizations is a series of defenses that man has put up against the dread of pure existence.

I can't find it right now, but there was a German study (also discussed on ET), that showed that, while people are generally becoming taller in developed countries, people in the U.S. have started becoming shorter (the study seemed to rule out genetic reasons).

Yes - as I've said before, anorexia is a recursive mental problem to do with wanting to be thinner (relative), rather than thin (absolute). It's the same problem with 'richer' and 'rich' = anglo nervosa
