摘要

Folate and vitamin B12 are involved in the carbon metabolism pathway supplying essential methyl groups for DNA and protein synthesis and play a vital role in individual health. They have also been shown to be associated with cardiovascular disease, especially stroke[1]. A recent study showed that stroke was the leading cause of death and disability-adjusted life years (DALYs) at the national level in China[2]. Therefore, the nutritional status of folate and vitamin B12 in the Chinese population is a concern. The elderly are more prone to develop folate and vitamin B12 deficiencies due to poor appetite, dental defects, and issues with digestion. Our previous study showed that insufficient dietary folate and vitamin B12 intake were particularly salient among rural elderly Chinese populations[3]. However, few studies have assessed folate and vitamin B12 status in vivo in this population.
