    Link between obesity and Caesarian section?

    This one seems incredible on the face of it, but there have been other studies finding the same link.


    "ROUGHLY one human pregnancy in ten presents complications (for example, breech presentation) that might justify the baby being delivered by Caesarean section. In some places that is not possible, and mother and infant have to take their chances with a normal delivery. But the opposite is also true. Elective Caesarean is becoming more and more common. In Brazil, Italy and Iran more than 40% of children are born this way."

    Caesarean section stops infants picking up, from their mother’s vaginas and perineums, bacteria that would normally establish themselves in a newborn’s gut, and by doing so improve its future health. Accumulating evidence suggests three things, in particular. These are that Caesarean babies are more prone than others to allergies (in which the immune system responds to inappropriate stimuli, such as nut proteins), to autoimmune diseases (in which the immune system attacks body cells, as happens in type-1 diabetes), and that they are also more likely to become fat."

    this could come about in one of two ways. Either the procedure itself keeps baby and bacteria apart or the large amounts of antibiotics which usually accompany the surgery are responsible. Since testing the distinction on people, though easy, would be unethical, Dr Dominguez-Bello turned instead to mice. She permitted some pregnant rodents to give birth naturally, while performing antibiotic-free Caesareans on others. She then raised the pups in identical conditions."

    her results were conclusive. At 15 weeks of age, pups that had been delivered naturally weighed an average of 39 grams. Their Caesarean-delivered kin averaged 45 grams. The probability of this difference resulting from chance is less than one in 1,000. Moreover, when Dr Dominguez-Bello examined the gut bacteria of her mice she found that those born naturally had a normal mixture while those born via Caesarean lacked Bacteroides, Ruminococcaceae and Clostridiales. These are all groups associated with lean bodies.It seems, then, that in mice—and by extension presumably in women—it is the operation itself rather than the associated antibiotics that are promoting bacteria-mediated obesity. "

    They should do a large human study using medical records. If the link is proved, then I guess it's just another case of
    "natural" being better, as is the case for breast feeding vs. bottle feeding.

    Interesting study. Both of my sons were born caesarean one weighed 8.8 and the other weighed 7.11 at birth. At their 2-week check-up, they each weighed 11 lbs. It would be an interesting study to go back through medical records to see growth.
