Question Answer
Define osteoporosis?chronic, progressive disease characterized by weak and fragile bones
Osteoporosis is caused by?abnormal bone production, accelerated bone destruction or buth
More than ____ million Americans are affected and it is assoc'd with an increased risk of _______, with its associated morbidity (pain, loss of independence, disability, nursing home placement) and mortality?10; fracture
List the risk factors for osteoporosis?1) advanced aged 2) hx of previous fracture 3) female gender 4) postemenopausal status 5) white or asian race 6) low body mass index 7) physical inactivity 8) tobacco use (both smoking and smokeless tobacco) 9) alcohol abuse 10) inadequate calcium or vitamin D intake 11) family hx of osteoporotic fracture 12) chronic use of certain medications (oral corticosteroids, antiepileptic drugs, depo-medroxyprogesterone, lithium, methotrexate, PPIs)
*** The USPSTF recommends screening all women > ____ years for osteoporosis (Grade B) as well as women aged ___ to ____ years w/ risk fxs that convey a 10 year risk of osteoporotic fracture > that of a 65 y.o. women?65; 50; 64
The USPSTF endorses the use of the _____ tool to calculate this risk? What is the website?FRAX,
Did the USPSTF find sufficient evidence to recommend for or against screening MEN for osteoporosis?no
The National Osteoporosis Foundation recommends screening all women ____ years, all men > ____ years, and men or women from 50-64 years with equivalent risk based on the ____ tool?65; 70; FRAX
If screening is normal and no risk factors are present, most experts recommend repeat testing no sooner than ___ to ___ years?10; 15
If treatment for osteoporosis is initiated, follow-up bone mineral density testing should be performed _____ years after the start of the treatment?2
Both the USPSTF and the NOF consider what screening test to be the preferred screening test for osteoporosis?dual-energy X-ray absorptiometry (DXA)
What scanning is the gold standard? What does it scan?1) central DXA scanning 2) lumbar spine and hip
Is peripheral DXA scans such as calcaneal assessments or US bone density testing recommended?no
The definition of osteoporosis is based upon the ____ score?T score
What is the T score?it is a comparison of the patient's bone density to that of a 30 year old reference
What is considered normal, in regards to the T score?T scores of 0 - 0.9 standard deviations below the reference mean are considered normal
How is osteopenia as defined by the T score?1.0 - 2.4
How is osteoporosis as defined by the T score?< 2.5
When does severe osteoporosis exist?when a fragility fracture (normal stress on an abnormal bone) occurs in patients with osteoporosis
Should patients w/ osteopenia and an elevated risk of fracture based upon the FRAX score be considered for treatment?yes
