Vitamin D has been known since the twentieth Century for its benefits in bone health. Recent
observational studies have demonstrated its benefits in infectious diseases such as tuberculosis and non-communicable
diseases such as diabetes mellitus, cardiovascular diseases and cancer. This has led to a dramatic increase in testing
among adults.
The cut-offs for vitamin D deficiency have been debated for decades and the current cut off is derived from a Caucasian
population. Studies done among black African adults in Africa are few with vitamin D deficiency ranging from 5
to 91%. A few cut- offs have correlated vitamin D deficiency to physiological markers such as parathyroid hormone
(PTH), calcium and phosphate with varying results.
