To the Editor: Widespread screening for vitamin D deficiency among healthy individuals in the general population is currently not recommended due to lack of supporting evidence. However, these considerations do not apply to patients at high risk for fracture, in whom testing and/or repletion of vitamin D is an integral part of pharmacologic osteoporosis management. Several factors may affect adequate repletion of vitamin D levels, including nonwhite race/ethnicity and obesity, which are both risk factors for low vitamin D level. The optimal repletion doses in these at-risk subgroups have not been determined. In the current era, studies examining vitamin D status among ethnically diverse populations identified for osteoporosis treatment remain limited. To better inform fracture prevention care for patients at high risk, this study examines the yield of vitamin D testing in women identified by their providers for initiation of osteoporosis therapy.
