Abstract：
The COVID-19 pandemic has resulted in substantial lifestyle changes with significant implications for nutritional health. Factors such as movement restrictions and disruptions in food supply chains led to the restricted availability of primary sources of essential micronutrients. To highlight this, we present the case of an elderly woman with an underlying subclinical cobalamin deficiency who developed symptomatic megaloblastic anemia, requiring hospital admission under lockdown conditions. This exemplifies how changes in diet during the COVID-19 lockdown have hastened the onset of B12 deficiency symptoms. Adverse outcomes can be avoided by identifying people at high risk of poor nutritional status and implementing policy initiatives that enhance their nutritional condition. This case report showed how important the B12 shortage was during the COVID-19 lockdown, especially for older people. They are more likely to be malnourished during COVID-19 for several reasons.
摘要：
COVID-19大流行导致生活方式发生重大变化，对营养健康产生重大影响。流动限制和食品供应链中断等因素导致基本微量营养素主要来源的供应受到限制。为了强调这一点，我们介绍了一名患有潜在亚临床钴胺缺乏症的老年妇女，该妇女出现了症状性巨幼细胞性贫血，要求在封锁条件下入院。这说明了COVID-19封锁期间饮食的变化如何加速了B12缺乏症症状的发作。通过确定营养状况不良的高风险人群并实施改善其营养状况的政策举措，可以避免不利结果。这份病例报告显示了在COVID-19封锁期间B12短缺的重要性，尤其是老年人。他们在COVID-19期间更有可能营养不良，原因有几个。
