At the lake of Zurich, every second child by caesarean

is not cut, The increase in the number of births by caesarean just a fad. Viennese researchers reveal in the journal "Proceedings of the Royal Society B" that the ever-growing babies are one reason for the rising cesarean section rate.

In China, Brazil, Egypt and Turkey, as known, also on the lake of Zurich - the cesarean section rates of around 50 percent, a clear indication that the intervention is often performed without direct medical reason. In Switzerland and in Austria the average is around 30 percent whereas in comparable countries, in Scandinavia, only about 15 percent.

In Italy, Portugal or Romania will, in turn, about 35 percent of the children via Cesarean section. The striking differences are mostly attributed to socio-economic, legal and cultural differences, it is said, in a press release of the University of Vienna.

Philip middle röcker from the Department of Theoretical biology research for some time to the causes and effects of this practice. In the present study, the evolutionary biologist and anthropologist, as well as his colleague Eva Zaffarini to the question, what is the role here of size changes of the mother and child over time.

babies grow faster as the birth canal

In the period between 1896 and 1996, the researchers calculated an average increase in the body size of the newborn of about a Millimeter per year. Until the 1960s, that was true of all the countries for which there were data. Responsible for this from an evolutionary point of view, rapid increase in significantly improved living conditions in many countries.

"but After the fetus is ahead compared to the mother of a Generation, is on average better environmental conditions than the mother," in mid-röcker. With their size, increase in the baby's outgrown in the cut but also the maternal birth canal. The better conditions, thus leading to a mismatch, more birth complications, and more C-sections.

Every tenth of a caesarean section due to Size

Between 1971 and 1996, however, the curve of the size of the increase levelled off in some industrialised countries and in many African countries, the development was reversed. "We have therefore set up the hypothesis that the environment influences changes in the body size-related during the last decades, the current caesarean section rate in a country," said the scientist.

Away from the respective socio-economic development, the state of the health system and medical risk factors in the different countries showed that in the period from 1971 to 1996, about one-third of the differences in the rates of caesarean section to the body size change and hence the average difficulty of the birth. The observed increase in the body of the baby's size to an average of one Millimeter per year, the caesarean Section Rate increases by about ten percent.

the WHO guidelines are questionable,

The study show once more how closely the reproduction and birth with the local socio-economic developments and changes in the immediate environment, it means in the outer extension. The throw is also the question of WHO-postulated to be aimed at the Emperor cut rate of ten to 15 percent.

in mid-röcker: "Human biology and health are not static but in flux, and can vary influenced by socio-economic and medical changes, locally." (nlu/oli/sda)
