Osteopenia is often a precursor to osteoporosis, a common condition of brittle bones that can result in fracture. The two medical terms are sometimes confused and it's important to know the difference and how each is related to arthritis. The biggest difference between osteopenia and osteoporosis is that osteopenia is not considered a disease while osteoporosis is. Instead, osteopenia is considered a marker for risk of fractures. Stigur Karlsson / E+ / Getty Images Osteopenia Explained Osteopenia results when the formation of new bone does not occur at a rate which can offset normal bone loss. Bone density scans have made this easier to measure. Prior to bone density testing, radiologists used the term osteopenia to describe bones that seemed more translucent than normal on x-ray, and the term osteoporosis described the occurrence of vertebral fracture. Bone mineral densitometry, or bone density scans, changed those definitions: Osteoporosis is defined by a T score of -2.5 or lower and osteopenia is defined by a T score higher than -2.5 but lower than -1.0. The T score is your bone density compared with what is normally expected in a healthy young adult of your sex. A T score above -1 is normal. Using this criteria, 33.6 million Americans have osteopenia. The significance of that statistic is similar to identifying who is pre-hypertensive or those who have borderline cholesterol. In other words, identifying a group that is at risk for developing a disease. Other Risk Factors for Fracture Osteopenia is only one risk factor for fracture. Other risk factors include: previous fractureage (risk of fracture increases with age)smoking (weakens bones)drinking more than two alcoholic drinks per day (increases risk of hip fracture)low body weight (increases risk of hip fracture)race and gender (white women have two or three times risk compared to men or black and Hispanic women)having a parent who had a hip fracturesedentary lifestyleinadequate calcium and vitamin D intakeconditions that increase the risk of falling such as poor vision, poor footwear, medical conditions that affect balance, use of sedative medications, or a history of fallstaking certain medications, including corticosteroids can result in glucocorticoid-induced osteoporosishaving certain medical conditions, such as rheumatoid arthritis or other rheumatic diseases can cause secondary osteoporosis Prevention Lifestyle changes can slow the progression of bone loss and decrease the risk of fractures. Lifestyle changes that can help prevent fractures include: maintaining a healthy weightparticipating in regular exercise, including weight-bearing exercise (walking, running, hiking, tennis are examples of weight-bearing exercise while swimming is non-weight-bearing)making sure you have enough vitamin D and calcium in your diet or by taking dietary supplementsno smoking 1:10 The Best Exercises to Prevent Osteoporosis Having regular bone density tests can help slow the progression of bone loss and decrease the risk of fractures by monitoring bone density measurements. The U.S. Preventive Services Task Force (USPSTF) found good evidence that bone density measurements accurately predict the risk for fractures in the short-term and formulated these recommendations for osteoporosis screening. Treatment Medications are used to treat osteoporosis but doctors (rheumatologists, gynecologists, internal medicine doctors, and geriatric specialists) who treat patients showing signs of early bone loss don't always agree on the best course. Should patients with osteopenia be treated with medications to prevent progression to osteoporosis? The National Osteoporosis Foundation, the American Association of Clinical Endocrinologists, and the North American Menopause Society recommend that patients with osteoporosis or fracture should be treated but there is inconsistency in what is recommended for people with osteopenia. Is treating osteopenia necessary or even cost-effective? Many experts believe that treating osteopenia with medications would not be cost-effective. But with additional risk factors, such as corticosteroid use or having rheumatoid arthritis, treating osteopenia becomes more of a consideration. It's important to remember that T scores alone cannot predict which patients with osteopenia will have fractures and which patients will not. Assessing all of the risk factors is the best way to decide whether treatment with osteoporosis medications is indicated. Patients with signs of early bone loss should focus on lifestyle modifications and discuss the benefits and risks of osteoporosis medications with their doctor. In patients with osteopenia but no history of fracture, doctors will use a calculator to come up with a metric called FRAX that helps decide who might benefit from prescription medication to decrease fracture risk. In patients with a 3% risk of a hip fracture over 10 years or 20% chance of fracture elsewhere, prescription medication may be recommended. Was this page helpful? Thanks for your feedback!
