Explain?
Real causal explanations are difficult to filter out I think. My opinion is more based on correlations.
However, I digged in a bit to see whether there are already some analysises available that could explain in plausible terms.
And found only many factors mentioned.
Also the WHO has nothing clear cut, and much is simple "explained" by country culture and tradition.
However.... I do see that the amount of home births has decreased strongly everywhere in the last decades... and that article I used in my post is as incorrect as my gutfeeling about the percentage home childbirth.
It reflects better the childbirths where a midwife was involved.
There is in many countries since WW2 a clear struggle between hospitals (doctors) and midwifes, where national insurances play a role as well.
I get back to it in a later post... because it is interesting
Medicalisation goes hand in hand with the commercial interests of the hospitals, but also the increased age of women getting a child, where complications come in.
Also on that medicalisation. The amount of Caesarian section births (C-section) has increased well beyond the 10-15% that the WHO considers as needed and advisable.
