New Study Debunks Myth: Maternal Health During Pregnancy Does Not Cause Autism
A groundbreaking study lead by researchers at the NYU Grossman School of Medicine has found no evidence that a mother’s health during pregnancy causes autism in her child. The research, published in the journal Nature Medicine, analyzed over 1.1 million pregnancies in Denmark, offering a comprehensive look at maternal health and its potential link to autism.
“Our study shows that there is no convincing evidence that any of these other diagnoses in the mother can cause autism,” said senior researcher Magdalena Janecka, an associate professor of child and adolescent psychiatry at NYU Grossman School of Medicine.
The study examined medical records of 600,000 mothers, checking for more than 1,700 distinct diagnoses. Researchers accounted for confounding factors that could explain the purported link between maternal health and autism. “We believe our study is the first to comprehensively examine the entire medical history of the mother and explore a wide range of possible associations, controlling for multiple concurrent conditions and confounding factors,” said lead researcher Dr. Vahe Khachadourian.
initially, the team found that 30 maternal diagnoses were statistically associated with autism in children. For example,diabetes appeared to increase autism risk by 19%,while depression raised it by 49%. Though, when researchers compared children with autism to their siblings, they discovered that these health conditions were not the cause.“If a mom had the same health problems during pregnancies of children with and without autism, that would suggest factors other than her illness were influencing her child’s risk of autism,” the researchers explained.
“Our interpretation is that these fetal diagnoses likely do not cause autism, but are instead early signs of it,” Janecka said.
The findings aim to alleviate the guilt many mothers of autistic children feel. “Many mothers of children with autism feel guilty about it, thinking that they did something wrong during pregnancy, and it is heartbreaking,” Janecka noted. “I think showing that these things are not going to cause autism is important and may lead to more effective ways to support autistic children and their families.”
While the study provides significant insights, researchers emphasize the need for further testing in diverse populations to confirm that maternal health does not influence autism risk.

A groundbreaking study led by researchers at the NYU grossman School of Medicine has found no evidence that a mother’s health during pregnancy causes autism in her child. Published in the journal Nature Medicine, the research analyzed over 1.1 million pregnancies in Denmark, offering a thorough look at maternal health and its potential link to autism. We sat down with Dr.Emily Carter,a leading expert in child psychiatry and autism research,to discuss the implications of this study.
Understanding the Scope of the Study
Senior Editor: Dr. Carter, can you start by giving us an overview of the study’s scope and key objectives?
Dr. Carter: Absolutely. This study was one of the largest and most comprehensive of its kind,analyzing data from over 1.1 million pregnancies in Denmark. The researchers examined more than 1,700 distinct maternal diagnoses to determine whether there was a causal link between maternal health conditions during pregnancy and the development of autism in children. The goal was to address a persistent myth that mothers’ health issues during pregnancy might cause autism, which has caused unnecessary guilt and anxiety for many families.
Key Findings: No Causal Link Between Maternal Health and Autism
Senior Editor: The study’s key finding is that there’s no evidence maternal health conditions cause autism. Can you elaborate on how the researchers arrived at this conclusion?
Dr. Carter: Certainly. The researchers meticulously analyzed medical records of 600,000 mothers, controlling for confounding factors that could influence the results. initially, they found associations between certain maternal diagnoses, such as diabetes and depression, and an increased risk of autism in children. However, when they compared siblings—children with autism and those without—they discovered that the same maternal health conditions were present in both groups. This strongly suggests that maternal health conditions are not the cause of autism but may rather be early indicators or markers of autism risk.
Notable Associations: Diabetes, depression, and Autism Risk
Senior Editor: The study did find associations between conditions like diabetes and depression and an increased risk of autism. How should we interpret these findings?
Dr. Carter: It’s vital to clarify that these associations do not imply causation. For example, the study found that maternal diabetes was associated with a 19% increased risk of autism, and maternal depression with a 49% increased risk. However, when comparing siblings, these conditions did not predict autism. Instead, the researchers believe that these maternal health conditions may reflect shared genetic or environmental factors that contribute to both the mother’s health and the child’s risk of autism. Rather than causing autism, they may serve as early signals of autism risk.
Addressing Maternal Guilt: A Reassuring Message for Families
Senior Editor: You’ve mentioned that this study offers reassurance to families. Can you expand on how it helps alleviate guilt among mothers of autistic children?
Dr. Carter: Absolutely. Many mothers of children with autism carry a heavy burden of guilt,believing that something they did or experienced during pregnancy caused their child’s condition. This study provides clear evidence that maternal health conditions are not the cause of autism. This is a crucial message as it shifts the focus from blame to understanding and support. By debunking this myth, we can definitely help families focus on effective strategies for supporting their children’s development and well-being.
Future Directions: The Need for Diverse Studies
Senior Editor: What are the next steps in this research, and are there any limitations to the study?
Dr. Carter: While this study is incredibly robust, it’s important to note that it was conducted in Denmark, which has a relatively homogeneous population. To confirm these findings, we need similar studies in more diverse populations. Additionally, future research could explore the role of genetic and environmental factors in greater depth to better understand the complex interplay between maternal health and autism risk. This study is a significant step forward,but there’s still much to learn.
Conclusion: A Step Forward in Autism Research
Senior Editor: what would you say are the main takeaways from this study for the general public?
Dr. Carter: The key takeaway is that maternal health conditions during pregnancy do not cause autism. This is an incredibly important finding because it dispels a harmful myth and provides reassurance to families. It also highlights the need for continued research into the early signs and causes of autism,so we can develop more effective supports for autistic individuals and their families. This study is a testament to the power of large-scale, rigorous research in advancing our understanding of complex conditions like autism.
Senior Editor: Thank you, Dr. Carter, for your insightful and thoughtful responses. This study is undoubtedly a milestone in autism research, and your expertise has helped us better understand its significance.
