Hello, my name is Bo Abrahamsen. I'm a professor at the University of Southern Denmark and the Research Center for Aging and Osteoporosis in Glostrup Hospital, Copenhagen. My talk today is Osteoporosis Calcium and Vitamin D. And I will try to talk about some studies that I think may be familiar to you. So it may be you'll find you'll have to go back and perhaps read the paper in question to fully understand what I'm getting at, so maybe one or two places. I'm not giving a lot of introduction. But rather, assume that you may have already read the papers. Because they've been really widely discussed in the past years.

As you probably know, there's difference in fracture risk in different parts of the world. And there's a little bit of a tendency for fractures to be rarer the nearer you get to the Equator. So that would of course drive the hypothesis that perhaps the lack of vitamin D in the Northern and Southern Hemisphere as you get away from the Equator would be one of the reasons there are more fractures. So if you look at the right hand of the slide, you'll see rates from the International Osteoporosis Foundation. And as you can see, Argentina, Iceland, and Norway all have fairly high fracture rates, whereas Central Africa and the northern part of Latin America all have low rates. And these are the very sun-rich areas of the world. But you can also see fairly high rates of fractures in the Middle East and in the European and Asian part of Turkey.
