Here's the thing. As I discovered after my second c-section, they call everything not an emergency section an elective section. So this is a case where the statistics are, IMO, hugely
misleading. My second c-section was for a footling breech. I was not offered the option of a vaginal birth and in all honesty was not comfortable with the thought of attempting it with that type of breech, but nontheless my section was marked down as "elective." (There were 3 choices: primary, emergent, and elective.) I'll tell you, I flipped out when I saw that. I was so upset over it!
I'm sorry; I know this isn't really what you're asking about. I wish you luck in writing your paper, but I doubt the type of woman to have a medically unneccessary c-section is the type to hang out at a place like Mothering.
We do have a handful of women who have had elective c-sections, as in they chose to have a c-section and were not pressured into them, but if you ask they will tell you they believe them to be medically necessary. For some women, any
risk of rupture is too much. And I respect that, because risk tolerance is a very personal thing, and far be it for any of us (IMNSHO) to tell her she should have been willing to take the risk.
