unfortunate racial disparities

I agree that improvement is needed when it comes to preventive testing and screening for osteoporosis, for all races, women and men. More knowledge of the state of our bone health is needed indeed. 

However, here's an interesting take on osteoporosis and racial disparity:

For many years milk has been pitched as a wonder food, whose calcium is the only protection we need against weak bones. Yet Americans have one of the worlds highest calcium intakes, but still suffer from one of the world's highest rates of osteoporosis.

For example: 

African women in the United States eat at least four times more calcium than African women in Africa, and have nine times more osteoporosis.

Asian women in the United States eat at least 60% more calcium than Asian women in Asia, and have three times more osteoporosis.

Calcium consumption in Hong Kong and Greece has doubled in the last 30 years, and the rate of osteoporosis tripled in Hong Kong, and more than doubled in Greece.

Question: Is our "racial disparity" really the issue, our is it more about our diet (or lack there of?)
