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

We measured the associations between vitamin B-12 status in infancy (2-12 mo) and the development and cognitive functioning in Nepalese children 5 y later. Vitamin B-12 status was assessed in infancy with the use of plasma cobalamin, total homocysteine (tHcy), and methylmalonic acid (MMA). At 5 y of age, we measured development with the use of the Ages and Stages Questionnaire, 3rd edition (ASQ- 3), and cognitive functioning by using the Developmental Neuropsychological Assessment, 2nd edition (NEPSY II), in 320 children.
