Vitamin B-12 status in infancy is positively associated with development and cognitive functioning 5 y later in Nepalese children

Abstract

Poor vitamin B-12 (cobalamin) status is widespread in South Asia. Insufficient vitamin B-12 status has been linked to poor neurodevelopment in young children. The objective of this paper is to measure the associations between vitamin B-12 status in infancy (2-12 mo) and the development and cognitive functioning in Nepalese children 5 y later.
