Children of mothers who have taken snus during pregnancy show higher blood pressure.

A research team found that children between the ages of five and six whose mothers had used snus during pregnancy had higher systolic blood pressure. The new study was published in the Journal of the American Heart Association.

Snus is a moist powdered tobacco for oral use that was banned in the European Union as early as 1992 after World Health Organization studies found it to be carcinogenic. However, this tobacco is very popular in some countries, such as Sweden, and is still available in the United States (although it is currently processed by the FDA in that country).

The snus is placed between the gums and the upper lip and essentially provides nicotine. The advantage of using such tobacco would be that it does not include the by-products of burning classic cigarettes. Another advantage is that it is not necessary to spit, as is the case with most common chewing tobacco cards.

This study shows that the intake of nicotine during pregnancy, whether from cigarettes, chewing tobacco or snus, is not safe and can have negative effects on the unborn child, as Felicia Nordenstam, a paediatric cardiologist at the Karolinska Institute University Hospital in Stockholm and lead author of the study, explains.

The researcher analyzed data from children born to 21 women who used only snus during pregnancy and compared it with data from 19 children whose mothers did not consume tobacco products during pregnancy.

Researchers found that systolic blood pressure in children in the first group was 4.2 mmHg higher than in children in the second group.
