In the United States today, 10 million people have osteoporosis (bone density that's about 25% less than a healthy young adult). In addition, 34 million more people have low levels of bone mass, placing them at increased risk. Osteoporosis is responsible for more than 1.5 million fractures annually, including 300,000 hip fractures, approximately 700,000 vertebral fractures, 250,000 wrist fractures, and more than 300,000 other fractures. About 68% of those affected by osteoporosis are women.
