  • Osteoporosis affects more than 200 million people worldwide.1
  • 34 million Americans are at risk of osteopenia.1
  • Acute and long term medical expenses associated with osteopenic fractures are estimated to be $474 billion over the next two decades.1
  • Studies indicate that an extra one million women wcreened for osteoporosis would reduce the cost of fracture treatment and hospital stays by $77 million.2
  • In the United States, the cost of all osteoporosis related fractures is currently equivalent to the combined treatment costs of cardiovascular disease and asthma.3
