Thanks, Sillysmile! Those numbers did look odd, and I agree - the low group size seems like the culprit here. And as the author of the website said, it's just one study. Even so, it's nice to see numbers. My years both in hard science and in non-profit work make me go "proof! show me proof! And methodology, and, and, and..." My husband has a tendency to sigh at me when I question the 30 second blurb on a study...
Yeah - based on the research I've been reading, I'm going to try and avoid insulin. It seems fairly controllable by diet & exercise, and insulin doesn't seem to add much benefit, while it does seem to add risk (to the mother, at least). Obviously whatever happens will be in some level dependent on the hospital I'm currently going with (the midwife group at said hospital), and I'm very much keeping my fingers crossed that if I *do* fail the 3 hour it won't change my birth plan. I don't know at what point they decide you're too high-risk to handle, or what changes they start making to your care. That will be a long talk.
Still, I've more or less been following a diabetic diet at this point anyways (not really consciously, it's just when I stopped to really think about it I realized there weren't many changes I'd make other than my breakfast bowl of cereal, and cutting back a bit on the sweets - but dark chocolate doesn't spike your blood sugar much at all, so I just need to grab some of that to munch on when I have a craving).
My mom was diagnosed with diabetes about two years back, so I'm pretty familiar with the dos and don'ts - even so, I'll be sitting down with her and going "advice! Give me!"
