C-section may double risk of childhood obesity

Babies who are delivered through Caesarean section are twice as likely to become obese as those born traditionally, US research suggests. Researchers from Boston Children’s Hospital in Massachusetts found a doubling in the odds of obesity by the time the child was three years old.

The team said birth by C-section might affect bacteria in the gut, which in turn affects the way food is digested. The study looked at 1,255 pairs of mothers and children from 1999 to 2002. The mothers joined the study before 22 weeks of pregnancy. Their babies were measured and weighed at birth and this was repeated at the age of three.

About one in four of the deliveries were C-section births and the remainder were vaginal deliveries. The team found a link between body mass, skin thickness and how a child was born. They also found that mothers who delivered by C-section tended to weigh more than those delivering traditionally, something which is known to influence obesity.

The researchers said another possible explanation was the difference in the composition of gut bacteria acquired at birth between the two delivery methods. They suggested expectant mothers who choose a C-section should be made aware of the obesity risk to their babies.
