We Really Don't Know the Effects Of Labour Interventions

 "Inducing labour may contribute to autism

Why babies were being induced in the first place still needs to be considered

The biggest study of its kind suggests autism might be linked with inducing and speeding up labour, preliminary findings that need investigating since labour is induced in increasing numbers of U.S. women, the authors and other autism experts say.
It's possible that labour-inducing drugs might increase the risk — or that the problems that lead doctors to start labour explain the results. These include mothers' diabetes and fetal complications, which have previously been linked with autism.
There is a growing consensus that risks for autism occur before birth or soon after.There is a growing consensus that risks for autism occur before birth or soon after.

Simon Gregory, lead author and an associate professor of medicine and medical genetics at Duke University, emphasized, "We haven't found a connection for cause and effect. One of the things we need to look at is why they were being induced in the first place."
Government data suggest 1 in 5 U.S. women have labour induced — twice as many as in 1990.
Smaller studies suggested a possible tie between induced labour and autism, but the new research is the largest to date, involving more than 600,000 births. The government-funded study was published online Monday in JAMA Pediatrics.
The researchers examined eight years of North Carolina birth records, and matched 625,042 births with public school data from the late 1990s through 2008. Information on autism diagnoses didn't specify whether cases were mild or severe. Labour was induced or hastened in more than 170,000 births.
Overall, 5,648 children developed autism — three times as many boys as girls. Among autistic boys, almost one-third of the mothers had labour started or hastened, versus almost 29 per cent of the boys without autism. The differences were less pronounced among girls.
Oxytocin and prostaglandins are used to start or speed up labour but the study doesn't identify specific medications.
The strongest risks were in boys whose mothers had labour started and hastened. They were 35 per cent more likely to have autism.
Among girls, autism was not tied to induced labour; it was only more common in those born after labour was accelerated; they were 18 per cent more likely to have the developmental disorder than girls whose mothers had neither treatment.
Autism affects about 1 in 88 U.S. children. Symptoms may involve communication problems including avoiding eye contact and unusual repetitive behaviour including arm-flapping. Causes are uncertain but experts believe it probably results from a combination of genetics and other factors. These may include mothers' illnesses and medication use while pregnant, fathers' age at conception, and problems affecting the fetus during childbirth — all suggested but not proven in previous research.
The study's biggest strength is bolstering the growing consensus that risks for autism occur before birth or soon after, said Dr. Byron King, director of Seattle Children's Hospital's autism centre. He was not involved in the study."

I am aware that nothing in this study is conclusive but it really makes you think about our lack of knowledge when it comes to the effects of any labour augmentation or assistance. There has simply not been enough research done or time elapsed to really see the full effect of the medical system's actions in pregnancy, labour and birth. It is terrifying to think about but the fact of the matter is we just don't know. I am NOT suggesting that there is no place for medical intervention when it comes to labour and birth because there most certainly is. In my short time as a doula I have witnessed labours that indeed would have ended in tragedy had medical advances not been available. Conversely, I have also attended births where medical interventions used were seemingly unnecessary and in some cases even harmful. I do believe there is a place in labour and birth for modern medicine but I know it is grossly overused in our society. Because long-term effects of these medical interventions are unknown I think we should not be so nonchalant with there uses and greater care and consideration should be used by those caring for women in labour.
