Conclusions
To our knowledge, this is the first study to determine the prevalence of
B12 deficiency in Aqaba province. Vitamin B12 levels were strongly and
significantly correlated with gender and Hb, RBCs, PCV and Platelet
count with non-significant relation to age and MCV. Additionally, the
study confirmed that Aqaba, like other southern regions in Jordan, is
characterized by a lower frequency of vitamin B12 deficiency compared to
the other regions in Jordan. Further studies are needed in other regions
of Jordan such as the eastern regions (Mafraq and Azraq) to complete the
national portrait of the vitamin B12 level in Jordan.
