Auckland researchers are launching a study aimed at demonstrating whether birth conditions are associated with asthma and obesity in children.
It is widely assumed that both relate to how it is best known for bacteria or bugs in our intestines and what it does for our health.
One third of all adults in New Zealand are obese and one-third of all children are overweight or obese in that country on the day they start school.
Researchers at the Liggins Institute of the University of Auckland suspect that there may be a link between bowel flora, also known as microbial and obesity.
Head researcher Wayne Cutfield wants to find out if the recommendations that cesarean birth can be associated with a higher risk of obesity is true.
"The guess is that babies born with caesarean section are not exposed to their maternal vaginal and perinatal germicide during this delivery process," Prof Cutfield said.
"Babies have relatively sterile bowels shortly before they are born and it is clear that the early colonization of this microbial bowel is very important."
He said that babies born from the evolutionary caesarean section "will not be exposed to their mother's germicide and their intestines will be inhabited by environmental bacteria, which are probably less healthy." So what has been suggested is the reason for the relationship between weather [birth] and a 30 percent increased risk of childhood obesity, and in fact a 30 percent increased risk of asthma as well. "
She is ready to check if there are differences in bowel bacteria among C category babies who have received a small amount of their mother's microbe just after birth and babies who have not received the treatment.
"What we are about to do is take the secretions of the mothers – vaginal and spinal secretions – to put them in a sterile aqueous solution and give them to babies orally, because when babies are born for several hours their stomach is not acidic" Professor Cutfield said.
He said adult stomachs were very acidic, which could kill such bacteria.
"But only for several hours after the birth of a baby his stomach is not acidic and the bacteria will swallow and descend into the intestine where we want to be."
Recent interim data from the Health Ministry show that there were 16,423 births in Section C in that country last year and that the proportion of these rooms increased from 10.3% in 2008 to 12.6% last year.
Professor Cutfield said that many twins were born from E selective incision, and the study offered twins for trial through obstetric groups who have registers of these conditions.
"If the study is positive and the treatments with the microbial breast really improve the health and well-being of children with regard to obesity and asthma, it's going to be simple to grow up and do."
Oakland Obstetrician Nicholas Walker said one of 20 of his patients in Section C is asking for a procedure known as "sowing," where the mother's microbe is transported to the baby shortly after birth, using a swab technique: After the baby is born, usually within half an hour, there is the possibility of taking the sword and gently coloring the nose and mouth, the lips, the ears and the eyes of the baby and the bottom of the baby where the bacteria are actually trying to enter the baby's body. "
Dr. Walker said that those who ask for it have thought about it and want it strongly.
He said bacteria such as e-coli and group B streptococcus may be associated with maternal germicidal secretions, but this could also be the case with vaginal birth.
"I do not think there is evidence of harm from it and there may be a benefit and so, without any harm, I think it makes sense to do it," he said about the "sowing" process.
An Auckland mother and healthcare professional, whom RNZ agreed to call "Susan," said she did her first baby two and a half years ago and had done from her obstetrician to the birth of her second child, the department, for medical reasons, 10 days ago.
"I can not really control what is happening about the birth of my children, but that was something I could contribute and I hope it has made a difference," Susan said.
He said both kids were good.
"I think it's wonderful, I think it's very hard to say if sowing has some effect on them until now but I guess it was one thing I could control in a fairly uncontrollable situation that I could not really choose how they were born."
Prof Cutfield said they would know within one to 15 months if bowel bacteria were different in children born from treated and untreated Cs.
However, if sections C increase the risk of obesity, they will not be known for up to five years.
