Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

In order to make bone health a reality for older adults, we need to consider the prevalence of Vitamin D deficiency in relation to environment latitude as well as vitamin D supplementation. Darker skin pigmentation and aging are known factors influencing the body's ability to synthesis adequate amounts of Vitamin D. The aim of this project is to document vitamin D deficiency in elderly African American women living in a southern latitude.
