The researchers in Bergen and Exeter used data from the Norwegian Mother, Father and Child Cohort Study and a similar study in the UK, the Avon Longitudinal Study of Parents and Children , to investigate the relationship between smoking and placental weight. The aim was to determine to what extent expectant mothers who quit smoking could impact the weight of the placenta at the time of birth.
Heavier placenta and fetal vulnerability The researchers used genetic analyses to solve this enigma and found increased placental weight in women who continued to smoke throughout pregnancy compared to those who quit smoking. The study revealed that the placenta increased by 182 g for mothers smoking in the first trimester and 202 g for those smoking until the end of pregnancy.

Quitting helps restore the balance Cathrine Ebbing is Professor at the Department of Clinical Science, UiB, and fetal medicine specialist at Haukeland University Hospital. She did not directly participate in the study and provides her expert commentary. "A malfunctioning placenta leading to growth restriction of the fetus is dangerous and can cause long-term health consequences for the mother and child.
