It turns out that smoking during pregnancy greatly affects the adolescent child’s obesity. This conclusion was made by Canadian scientists who published their research in the journal Archives of General Psychiatry.
"The effect of cigarette smoke on a child in the womb of a smoking mother is a known factor in the development of obesity, but the mechanism has not yet been known. Probably the reason for the child gaining excess weight is the preference for more fatty foods due to the improper reward system of the brain" - say the author and specialists of the Children's Hospital in Toronto.
In general, scientists investigated 378 adolescents aged 13 to 19 years. All children were divided into two groups: those whose moms smoked during pregnancy, and those whose moms did not smoke in an interesting position. Moreover, smokers were considered those mothers who smoked more than one cigarette per day during the second trimester of pregnancy. Non-smokers were considered those women who did not smoke, either before or after pregnancy.
The researchers found that children of smoking moms have significantly greater weight and body mass index, regardless of age, gender and height. It turns out that in adolescents whose mothers smoked during pregnancy reduced a certain proportion of the brain that controls and limits the consumption of fatty foods. This is what causes the obesity of children of smoking moms, according to Canadian scientists.
