The relationship between geographical location and vitamin B12
levels.
The results of this study support the previous findings for the four
regions in Jordan; Irbid, Karak, Tafila, and Ma’an, where the
percentages of B12 deficiency in these regions were 41%, 35%, 27% and
26% respectively 57.
The current study evaluated B12 deficiency in Aqaba, which was found to
be 24.6%. Figures 2 and 3 illustrate a comparison between the
frequencies of vitamin B12 deficiencies in five regions that cover
Jordan from north to south.
