>> first of all, i want to make clear at the top, this is an observational study. no one is saying it's a cause and effect here. it's concerning to a lot of people. it's going to capture a lot of headlines. no one can say inducing labor leads to autism, this study was an observational study, looking at boys and they found that there was an association between inducing labor, augmenting labor and having a boy that's subsequently at higher risk of autism. let me show you some numbers really quick. first of all, inducing labor means a woman is around her due date she has not yet developed contractions, you give medicines to start those contractions. augments means the contractions have started, but you're going to make the contractions even stronger. take a look at the numbers there, if someone induces, it's about an 18% increase in the likelihood of having a boy with autism. slightly lower if just augmenting, 15%. if you do both, 35% increase overall, and likely to have a boy with autism. >> how common is augmenting or inducing? >> i looked this up as well.
