much more common than i found. overall, inducing labor is about 23%, about a quarter of women have their labor induced. and those numbers are from 2008, the last time it was really recorded, my guess is, it's a little higher now. it's a little lower than most people expected, it's not all women. >> as you mentioned, the findings were much more pronounced among boys, do you know why there's a gender gap? >> i don't know why there is, this could be one of those things where we don't know which came first. we know boys are more likely to have autism than girls. they say one in 88 children, but if you look more specifically at the numbers, among boys, it's one in 54, among girls, it's one in 252, it could mean that more boys are having autism or this is playing some role. we don't know. >> what does that actually -- i'm practically speaking, what should families do, should people stop inducing or augmenting pregnancies?
