Health: Smoking While Pregnant can Lead To Childhood Obesity

​Children born to mothers who smoked during pregnancy are more likely to be overweight or obese than if the mother did not according to research from the University of Aberdeen.

The data were gathered using the Aberdeen Maternity and Neonatal Databank (AMND) – a repository unique to Aberdeen, that holds data on all births at the maternity hospital since the mid 1950’s. 
The results, published in the journal Paediatric and Paediatric Epidemiology, found that if the mother started smoking in-between pregnancies, the younger child had increased BMI compared to their older unexposed brother or sister.

Dr Steve Turner who led the study said: “This study looked at the relationship between maternal smoking and

childhood obesity . Previous studies have identified a link between the two but saying that one causes the other is problematic because there are lots of other factors that might explain this relationship, for example people from a poor communities are known to smoke more than those in more affluent communities. Also, children in those communities tend to be more obese so it may be that the relationship between smoking and obesity is actually explained by socioeconomic status.

“However, by conducting a sibling comparison study, we can look at the relationship between pre-natal smoke exposure and child BMI within a family and this way we can make sure that things like socioeconomic status are the same. Therefore, any difference between siblings is likely to be explained by the change in smoking. We predicted that when a mum has two pregnancies and if she starts smoking between those two pregnancies, the younger child who is exposed to smoke is more likely to be obese according to BMI and that is what we found.

“This study adds to the huge body of evidence that maternal smoking in pregnancy is harmful and the harm isn’t just limited to the pregnancy itself – it lasts well-beyond the pregnancy .

“To sum, the relationship between

maternal smoking and offspring obesity is complex and is partly explained by other factors but this study provides good evidence that strengthens the association between the two.”
