Association of maternal and cord vitamin B12 levels with anthropometry in term neonates born to malnourished mothers in coastal South India.

There was a positive correlation between birth weight, length, and maternal vitamin B12 levels in malnourished mothers. These findings emphasize the need to address maternal malnutrition and vitamin B12 deficiency to improve neonatal health.
