RESUMO
This study aimed to estimate the status of serum vitamin B12 level in patients attending Jordan University Hospital in Amman, and to examine the relationship with demographic data, chronic illness, dietary habits, haematological parameters and symptoms related to vitamin B12 levels. A total of 838 patients completed a questionnaire and gave blood samples; 44.6% were vitamin B12 deficient (< 180 pg/mL) and 34.2% had hypovitaminosis (180-300 pg/mL). Vitamin B12 deficiency was associated with memory impairment, low meat intake and strict vegetarian (vegan) diets. The high frequency of low vitamin B12 warrants the development of a strategy to correct this problem in Jordan.

This study aimed to estimate the status of serum vitamin B[12] level in patients attending Jordan University Hospital in Amman, and to examine the relationship with demographic data, chronic illness, dietary habits, haematological parameters and symptoms related to vitamin B[12] levels. A total of 838 patients completed a questionnaire and gave blood samples; 44.6% were vitamin B[12] deficient [< 180 pg/mL] and 34.2% had hypovitaminosis [180-300 pg/mL]. Vitamin B[12] deficiency was associated with memory impairment, low meat intake and strict vegetarian [vegan] diets. The high frequency of low vitamin B[12] warrants the development of a strategy to correct this problem in Jordan
