More Parents Forgo Crucial Newborn Injection: "Worrying" Trend

A growing number of parents in Sweden are declining the K-vitamin injection for their newborns, a decision that researchers deem "worrying" due to the increased risk of serious bleeding. The routine injection, administered to prevent rare but severe internal hemorrhages, is being refused by a larger percentage of parents than in previous years.

It is worrying. Above all because we know that K-vitamin can protect children from bleeding related to K-vitamin deficiency.

A Swedish register study, encompassing over two million children born between 2003 and 2021, revealed a steady increase in newborns not receiving the K-vitamin shot. While the overall percentage remains low, it more than doubled from 0.66 percent in 2006 to 1.50 percent in 2021. This trend is particularly pronounced in home births.

The study highlighted a significant consequence: infants who did not receive the injection faced a higher risk of bleeding in their first six months, including a nearly threefold increased risk of bleeds in or around the brain. Even those who received K-vitamin drops instead of an injection showed an elevated risk compared to those who received the shot.

What we see in other studies is that parents are afraid it will hurt or for side effects. Sometimes they think an increased intake of K-vitamin in the mother's diet is enough. There are also parents who mistrust healthcare in general, and I think increased skepticism towards vaccines can play a role.

Researchers are exploring the reasons behind this parental hesitancy. Eleni Simatou, a doctoral student and pediatric neurologist involved in the study, suggests potential factors include fear of pain or side effects, a belief that maternal diet is sufficient, or a general mistrust of healthcare providers. She also noted a correlation with vaccine hesitancy, as parents who refuse K-vitamin are often also hesitant about vaccinations.

You have to take K-vitamin once a week for twelve weeks, and there is a risk that you miss a dose or stop. If the child has a liver problem, it also becomes more difficult to absorb K-vitamin.

Simatou emphasizes the need for continued education for both parents and healthcare professionals about the benefits of K-vitamin and the risks associated with opting out. She believes that clear communication from pediatricians during discussions with parents is crucial to ensure they understand the implications of their decision.

We don't know if they know what they are saying no to. It is also important that we pediatricians explain and have the discussion with the parents.
