Rheumatoid arthritis is a condition that affects roughly 1.5 million people in the US and approximately 1% of the global population. The highest incidence of rheumatoid arthritis occurs in women ages 44-65 though it can occur at almost any age and in both genders. While it may seem unusual that for almost no apparent reason, there are three times as many women affected than men, it is important to realize that rheumatoid arthritis is an autoimmune condition and women have a higher risk of developing autoimmune diseases in general compared to men.

Osteoporosis affects more than 28 million people in the US and is the major underlying cause of bone fractures in postmenopausal women and the elderly. Approximately 10 million have osteoporosis and the other 18 million have osteopenia, a low bone mass condition that, if left unchecked, can develop into full blown osteoporosis.
