Is osteoporosis screening in postmenopausal women effective

First, osteoporosis is common, and its prevalence increases with age (strength of recommendation [SOR]: A— prospective cohort studies). Second, low bone mineral density predicts fracture risk (SOR: A—prospective cohort studies). Finally, the likelihood of osteoporotic fracture is reduced with therapy, such as alendronate 10 mg/day or risedronate 5 mg/day plus adequate daily calcium and vitamin D (SOR: A—meta-analysis of randomized clinical trials).
