Newsie – Scientists suspect that there is a link between C-shaped births and obesity and asthma


Researchers in Auckland are beginning research to determine whether Caesarean delivery is associated with childhood asthma and obesity.

It is speculated that these two are related to each other when more is known about bacteria or worms in our intestines and what they do with our health.

One third of all adults in New Zealand are obese and one third of all children are overweight or obese in this country on the day they start school.

Researchers at the Liggins Institute in Auckland University now suspect that there may be a connection between intestinal flora, also known as microbiome, and obesity.

The research scientist, Wayne Cutfield, wants to find out if the caesarean delivery suggestions may be associated with a higher risk of obesity is true.

"Speculation is that children born via caesarean section are not exposed to the vaginal microbiome and mother's crotch during this delivery process," says prof. Cutfield.

"Children have relatively sterile intestines just before birth, and clearly early colonization of this intestinal microbiome is really important."

He said that children born by the electoral imperial section "will not be exposed to their mother's microbiome, and their intestines will be populated by environmental bacteria that are probably less healthy." So what has been proposed is the cause of the relationship between the imperial mushroom. [birth] and a 30% increased risk of childhood obesity, and an increased risk of developing asthma by 30%. "

He intends to check if there are differences in intestinal bacteria between children in section C, who were given a small amount of their mother's microbiome shortly after birth, and children in section C who did not receive treatment.

"What we are going to do is take maternal secretions – vaginal and crotch secretions – put them in sterile water solution and give the child orally, because when children are born for a few hours, the stomach is not sour." Professor Cutfield said.

He said that adults' stomachs were very acidic, which would kill such bacteria.

"But for a few hours after the birth of a child, his stomach is not sour, and the bacteria will be swallowed and go down to the intestines, where we want them to be."

Recent temporary data from the Ministry of Health show that last year there were 16,423 births in section C in this country, and the percentage of these imperial selections increased from 10.3 percent in 2008 to 12.6 percent last year.

Professor Cutfield said that many twins were born using scheduled C, and the study recruited twins to be examined by obstetric groups that have records of these situations.

"If the test is positive and the mother's microbiome treatment really improves the health and well-being of children in terms of obesity and asthma, it will be easy to scale and do."

An observer from Auckland, Nicholas Walker, said one of the 20 patients in his C-section is asking for a procedure called "sowing" in which the mother's microbiome is transferred to the baby soon after birth, using the swab technique: "After birth a baby, usually within half to one hour, there is a chance to take a swab and gently paint the nose and mouth of the child, mouth, ears and eyes and the lower part of the child, where the bacteria would basically try to enter the child's body. "

Dr. Walker said those who asked for it thought about it and wanted it.

He said that bacteria such as e-coli and group B Streptococcus may be associated with secretions of the mother's microbiome, but this may also be the case with vaginal birth.

"I do not think there is evidence of damage and can bring benefits, so in the absence of damage, I think it is reasonable," he said of the "sowing" procedure.

A mother from Auckland and a health care worker who RNZ agreed to call "Susan" said she did it herself for her first child two and a half years ago, and her midwife gave birth to a second child, through the C-section, for medical reasons, 10 days ago.

"I can not really control what happens to the birth of my children, but it was something I could contribute to and I hope it made a difference," said Susan.

She said that both children are doing well.

"I think they are wonderful, I think it's hard to say whether sowing had any effect on them, but I think that was one thing I could control in a rather uncontrollable situation, not being able to choose how they were born."

Professor Cutfield said that within a year to 15 months he would find out if the intestinal bacteria differ in C-born children who have been treated and not treated.

However, whether the C-sections increase the risk of obesity, will not be known for up to five years.
