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.
本研究旨在评估在安曼的约旦大学医院就诊的患者的血清维生素 B12 水平状况，并研究其与人口统计学数据、慢性疾病、饮食习惯、血液学参数以及与维生素 B12 水平相关的症状之间的关系。共有 838 名患者完成了问卷调查并提供了血样；其中 44.6%的患者维生素 B12 缺乏（<180pg/mL），34.2%的患者为维生素 B12 不足（180-300pg/mL）。维生素 B12 缺乏与记忆力减退、低肉类摄入和严格素食（纯素）饮食有关。低维生素 B12 的高频率表明有必要在约旦制定一项策略来纠正这一问题。
