How Often Should Bone Density Testing Be Done?

Not as often as you think, even though Medicare may be willing to pay for it every two years. Via Science Daily:

Now a new study led by Margaret L. Gourlay, MD, MPH of the University of North Carolina at Chapel Hill School of Medicine finds that women aged 67 years and older with normal bone mineral density scores may not need screening again for 10 years.

“If a woman’s bone density at age 67 is very good, then she doesn’t need to be re-screened in two years or three years, because we’re not likely to see much change,” Gourlay said. “Our study found it would take about 16 years for 10 percent of women in the highest bone density ranges to develop osteoporosis. That was longer than we expected, and it’s great news for this group of women,” Gourlay said.

The researchers suggest that for T scores > -1.5, repeat testing needn’t be done for 10 years. Women with T scores between -1.5 and -2.0 can be re-screened in 5 years, and those with T scores below -2.0 can have every other year testing as is done now.

To be honest, I’ve been spacing out bone density testing in woman with good baseline scores for some time, but not knowing how long I can go. This is great information for me and for my patients.

Eat To Save Your Life: Another Half-True Diet Book

I am hesitant to review diet books because they are so often a tangled mess of fact and fiction. Teasing out their truth from falsehood is about as exhausting as delousing a long-haired elementary school student. However after being approached by the authors’ PR agency with the promise of a…
