Vertebral fractures.

摘要

to the editor: Ensrud and Schousboe (April 28 issue) recommend daily intake of 1000 to 1200 mg of calcium and 600 to 800IU of vitamin D for the prevention of vertebral fractures in postmeno-pausal women. Even though this recommendation is in keeping with recent guidelines, it does not take into consideration the association between calcium supplementation and increased risk of cardiovascular events, as reported by Bol-land et al. in a recent meta-analysis.
