Cesarean section is a progress of modern medicine, making many dystocia Of the pregnant women, mother and son were saved. In the past ten years, the proportion of caesarean section has become higher and higher worldwide. The caesarean section rate in China is 46%, ranking first in the world. The caesarean section rate in other countries is also higher than the actual required level. The caesarean section rate in British public hospitals is about 25%, while that in private clinics is as high as 60%.
Cesarean section is more and more convenient for doctors and mothers, but this convenience has a price. Natural delivery is a natural way of delivery. The babies born naturally have many advantages over those born by caesarean section. The baby day of caesarean section will have some health problems.
A Danish survey of 34000 children found that babies born by caesarean section were four times more likely to suffer from respiratory infections than those born naturally.
Another study found that babies born by caesarean section had obesity The risk is twice as high as that of a naturally born baby. Another study found that pregnant women with the first cesarean section were more likely to have placenta previa when giving birth to the second child.
In addition to health problems, are there any intellectual differences between the two delivery methods?
Some previous studies have found that babies born by caesarean section are more intelligent than those born naturally, and rarely endorse caesarean section, but recent studies have denied this conclusion.
A study conducted by Iranian scientists in 2010 compared children aged 6-7 years old and confirmed the previous research results, that is, the intelligence test score of caesarean babies is high, but it was found that it is related to the educational level of parents. Because the parents of caesarean babies are generally highly educated, children receive better education conditions, especially early education, during their growth, These children's intelligence test scores are high. After removing factors such as parents' education level and mother's age, it was found that there was no significant difference in intelligence test between infants born naturally and those born by caesarean section.
This study shows that people with high education level are more likely to have caesarean section, which is one kind of over treatment.
In 2012, a study by American scientists found that the level of a special protein called UCP2 was higher in mice that were delivered naturally than those that were delivered by caesarean section through the study of the hippocampus region on the mouse model. This protein can promote short-term and long-term memory and contribute to intellectual development in adulthood. This protein can also improve the chances of breast-feeding of newborns, which explains why the level is high in naturally born mice.
Although this research is only the result of animal experiments, it provides evidence for the mechanism that babies born naturally are smarter. But it is also because of the results of animal tests, whether the same situation will occur in the population has yet to be confirmed. In addition, the high level of UCP2 protein does not mean that you will be smart. Because human intelligence has a great influence on children's intellectual development. Family conditions, parents' words and deeds, education level, competitiveness of learning environment, etc. may affect children's intellectual development.
Are babies born naturally smarter? So far, we can't draw a conclusion and need further study. But at least it can be said that babies born naturally are not stupid and have no intellectual problems. According to limited research, they may have certain advantages in intellectual development over babies born by caesarean section. On this basis, in addition to some possible health problems of cesarean section, it is enough to remind doctors and pregnant women that if they can have a natural birth, they should strive for a natural birth, and cesarean section can only be carried out when it is really impossible.
