Question

What population group has the highest risk for vitamin K deficiency? ​

Quizplus · Accepted Answer

Newborns have the highest risk for vitamin K deficiency due to limited transfer of vitamin K from the mother during pregnancy, low levels of vitamin K in breast milk, and an immature gut microbiome that is unable to synthesize vitamin K. This puts them at risk for bleeding disorders, including vitamin K deficiency bleeding (VKDB). Infants are typically given a vitamin K injection shortly after birth to prevent this deficiency.
