Induced Labor Does Not Increase Autism Risk

Induced labor does not increase risk for autism spectrum disorders
Risk of autism should not interfere with the decision to induce labor

Autism is a developmental disorder that affects many children and is characterized by

Language acquisition
Behaviour repetitions
Impairment in social interaction

Studies conducted on autism reveal that

1 in 68 children in the U.S is found to be affected with autism.
1 in 38 children in India is affected with autism.
Boys are 4.5 times more likely to have autism than girls.

An autistic child requires patience and support through the growing years and there are many support groups and training programs that help a parent look after the autistic child. However, a new study has shown that inducing labor will not increase the risk for autism.

Inducing Labor

Autism Causes, Symptoms, Diagnosis, Treatment, Prognosis
Autism is a neurodevelopmental disorder typically characterized by impaired social and communication skills combined with repetitive movements.

‘Risk of autism should not affect medical decision to induce labor.’

Doctors resort to inducing labor when labor does not start on its own and when waiting for natural labor could affect the health of the unborn child. The various methods of inducing labor are

Cervical ripening
Administration of oxytocin
Rupturing the membrane

Previous Study Shows Induction Of Labor Increases Risk Of Autism

An earlier study by Simon G. Gregory and published in JAMA in 2013 carried out a population-based study on 625,042 births in North Carolina and their subsequent school records to ascertain if they had autism.

Quiz on Autism
Autism spectrum disorder is a complex genetic disorder that impairs social, behavioral, and communication functions in humans. Autistic people may act, communicate, interact, and learn differently than most other people. ASD usually begins in childhood and can last for the rest of a person's life, though symptoms may improve over time

The study found that

1.3% of male children had autism
0.4% of female children had autism

While the authors of the study concluded that the induction of labor drastically reduced stillbirth among women with high sugar levels or high blood pressure, there existed a risk factor that increased chances of autism.

The study gathered popularity as it hypothesized that eliminating induction of labor could remove 2 autism cases for every 1000 births.

Labor-Introduction
Childbirth is one of the most marvelous and memorable segment in a woman's life that calls for celebration. Knowledge about labor and delivery can ease unnecessary fear, ensuring a unique experience.

Current Study Shows No Increase In Risk Of Autism On Inducing Labor

The current study was carried out by Harvard Chan School researchers, Sweden's Karolinska Institute and Karolinska University Hospital, Indiana University and Harvard Medical University. They studied one million live births during the year 2013 and followed up the births by checking for the presence of neurological development disability.

Cervical Ripening - Methods, Benefits, Risks
Cervical ripening refers to the softening of the cervix which precedes the onset of labor and is necessary for cervical dilation and passage of fetus.

The study found that

2% of study population were diagnosed with autism
11% of the deliveries were induced, with pregnancy complications that included
- Gestational hypertension
- Gestational diabetes
- Pre-eclampsia
23% of the induced labor cases were post term

When the researchers studied induced labor and then followed up with assessing the development of the baby, they found an association between induced labor and risk of autism.

Sibling Study

Researchers studied the effect of induced labor on siblings, where one child was born after inducing labor while the other child wasn’t. There was no association identified.

Dr Anna Sara Oberg who is the lead author of the study and a research fellow in the Department of Epidemiology at Harvard Chan School cautions that "It is important to note that the findings pertain to the risks associated with labor induction per se, and not the specific method or medication used in the process, including oxytocin,"
