There are numerous factors that can influence the risk of autism in a child. By understanding these, families can make informed decisions during pregnancy to potentially reduce the risk of autism.
Research suggests that genetics play a significant role in determining whether a child is born with autism. In some rare cases, exposure to certain chemicals during pregnancy can lead to birth defects, potentially contributing to autism. Understanding family history and genetic predispositions can help in making proactive decisions during pregnancy. For more information, refer to our article on autism and prenatal development.
In addition to genetics, certain lifestyle changes during pregnancy can contribute to the health of the baby. These changes may include regular medical check-ups, a well-balanced diet, regular exercise, and diligent prenatal care.
Taking recommended vitamins and supplements is also essential, as is avoiding harmful substances like illicit drugs and alcohol. Pregnant women should also seek treatment for existing health conditions, such as celiac disease or PKU, and get vaccinated for German measles (rubella) before pregnancy to prevent rubella-associated autism.
While it's important to note that these strategies do not guarantee autism prevention, they can contribute to overall prenatal health and increase the odds of having a healthy baby. For more about what to expect during pregnancy, consider reading our article on autism symptoms during pregnancy.
The steps towards autism prevention during pregnancy are multifaceted, involving both understanding genetic influences and making healthy lifestyle decisions. By taking these factors into account, families can take proactive steps towards ensuring a healthy pregnancy and possibly reducing the risk of autism.

Understanding the impact of maternal health on the risk of autism is a key component of autism prevention during pregnancy. Various factors come into play, including the age of parents at the time of birth, birth order, and maternal birth place.
Research suggests that maternal age at birth plays a significant role in autism risk. According to a study cited by NCBI, women over 30 had a higher risk of having a child with autism. The risk increased by 27% for women between 30-34 years compared to those between 25-29 years. For women over 40, the risk was higher by 106% compared to women under 30. Therefore, as part of autism prevention during pregnancy, it's important to consider maternal age and associated risks.
Similarly, paternal age at birth has been found to be a risk factor for autism. According to the same NCBI study, a five-year increase in paternal age was associated with a 3.6% increase in autism risk. This suggests that both maternal and paternal ages are significant factors in autism prevention.
Birth order also appears to play a role in autism risk. The NCBI study found that first-born children had a 61% higher risk of autism compared to children born third or later. This suggests that subsequent pregnancies may have a protective effect, although the reasons for this are not yet fully understood.
Maternal birth abroad has been marginally associated with an increased risk of autism. The meta-analysis conducted by NCBI found a 28% increased risk of autism in children whose mothers were born abroad. This suggests that environmental factors in different countries, or the experience of migration and acculturation, may have an impact on autism risk.
These maternal health factors provide crucial insights into the complex picture of autism risk. However, it's important to note that many cases of autism cannot be attributed to these factors alone. Autism is a complex condition with a range of influences, including genetic, environmental, and potentially, other unknown factors.

Various health conditions during pregnancy have been linked to an increased risk of autism in offspring. This section will explore the potential impact of maternal diabetes, medication use, pesticide exposure, and hormone abnormalities on autism risk.
Several studies have demonstrated a strong correlation between maternal diabetes and an increased risk of autism. Maternal gestational diabetes, in particular, is associated with a two-fold increased risk of autism. Additionally, maternal pre-existing type 2 diabetes is also significantly associated with the risk of Autism Spectrum Disorder (ASD) in offspring, albeit slightly lower than gestational diabetes diagnosed by the 26th week post-gestation [2].
Moreover, maternal diabetes during pregnancy has been found to induce autism-like behavior in offspring. This is believed to occur due to hyperglycemia suppressing SOD2 expression through oxidative stress-mediated histone methylation, which contributes to autistic behavior in offspring [2].
Maternal medication use during pregnancy has been associated with a 46% increased risk of autism. It's important to consult with a healthcare provider to understand the potential risks and benefits of medication use during pregnancy, particularly in the context of autism treatment during pregnancy.
Maternal exposure to pesticides during pregnancy, such as glyphosate, has been linked to an increase in autistic-like behaviors in offspring. This includes social interaction deficits and cognitive deficits. These effects are believed to be due to increased expression of soluble epoxide hydrolase (sEH) in the brains of offspring after maternal glyphosate exposure, with sEH inhibitors able to restore the effects of maternal glyphosate exposure on inducing autism-like behaviors in offspring.
Hormone abnormalities in pregnant women, such as prenatal progestin exposure, have been linked to an increased risk of autism in offspring. Prenatal exposure to synthetic progesterone can induce autism-like behaviors by inhibiting estrogen receptor β (ERβ) in offspring. ERβ agonists and/or overexpression of ERβ may help improve autistic behavior induced by prenatal progestin exposure [2].
Understanding these health conditions and their potential impact on autism risk is crucial for promoting effective autism prevention during pregnancy. For more information on early detection, consult our article on autism screening during pregnancy.
Nutrition plays a pivotal role in fetal development, with several studies suggesting its potential influence on the risk of Autism Spectrum Disorder (ASD). In this section, we delve into the role of prenatal vitamins, maternal diet, fatty acids, and Vitamin D in autism prevention during pregnancy.
Prenatal vitamins are crucial for the healthy development of the fetus and may also play a role in lowering the risk of ASD. According to the National Institute of Environmental Health Sciences, NIEHS-funded studies have suggested that taking prenatal vitamins might provide protective effects, especially for those exposed to certain environmental contaminants during pregnancy. Moreover, higher or moderate intake of prenatal/multivitamins, folic acid, and Vitamin D was associated with reduced odds of ASD, as per a study published on NCBI.
The mother's diet during pregnancy plays a significant role in the child's neurodevelopment. Prenatal vitamin/multivitamin use and adequate intake of folic acid and Vitamin D are associated with a lower likelihood of having a child with ASD [4]. It's suggested that a balanced diet rich in essential nutrients can potentially minimize the risk of ASD. For comprehensive information on autism symptoms during pregnancy, please refer to our article on autism symptoms during pregnancy.
While the role of fatty acids in autism prevention requires further research, it's hypothesized that certain fatty acids might contribute to brain development and function. Some studies suggest that omega-3 fatty acids, found in foods like fish and flaxseeds, could help support healthy brain development. However, more research is needed to confirm these findings and determine the optimal intake of fatty acids during pregnancy.
Vitamin D has emerged as a nutrient with a growing body of evidence supporting its protective association with ASD. Studies focusing on both neonatal and maternal levels have yielded similar findings. These studies suggest the importance of adequate Vitamin D levels during pregnancy for reducing autism risk.
In conclusion, while the nutritional factors outlined might help in autism prevention during pregnancy, it's essential to remember that nutrition is just one aspect of prenatal health. A comprehensive approach encompassing genetic factors, lifestyle habits, and medical history is essential for minimizing autism risk.

Understanding the link between certain medications and the risk of autism can play a critical role in autism prevention during pregnancy. This section discusses the impact of antiepileptic drugs, antidepressants, and neurotransmitter medications on autism risk.
Research has established a connection between the use of certain antiepileptic drugs during pregnancy and an increased risk of autism. For example, the use of valproate may raise the risk of autism by as much as 10% according to multiple large, well-researched studies. Given this, it is crucial for women who are pregnant or planning a pregnancy to discuss potential alternatives with their healthcare provider. For more information about autism symptoms during pregnancy, you can visit our section on autism symptoms during pregnancy.
Antidepressants, particularly selective serotonin reuptake inhibitors (SSRIs), used during pregnancy have also been linked to an increased risk of autism in children. This link was supported by a 2015 systematic review and meta-analysis [5]. This does not mean women should discontinue their antidepressants if they are planning a pregnancy, but rather they should discuss their options with their healthcare provider. It's important to balance the potential risks to the fetus with the risks of untreated depression to the mother. Look into our autism screening during pregnancy page for more details.
In contrast to antiepileptic drugs and antidepressants, most medications that target neurotransmitter systems do not appear to increase the risk of autism when used during pregnancy. Research conducted at The Seaver Autism Center for Research and Treatment at the Icahn School of Medicine at Mount Sinai found that babies exposed in the womb to the majority of these medications were not more likely to develop autism than non-exposed babies [6]. However, it's still important to discuss any medication use during pregnancy with a healthcare provider. For more insights on autism and prenatal development, check out our page on autism and prenatal development.
It's important to note that while certain medications may increase the risk of autism, they are just one piece of a complex puzzle. Autism is believed to be caused by a combination of genetic and environmental factors, and further research is needed to fully understand these influences. Always consult with healthcare providers before making any changes to medication use during pregnancy. For more on this topic, you can explore our resource on autism treatment during pregnancy.
While genetic and lifestyle factors play significant roles in autism risk, there are other influential factors that are worth considering in the context of autism prevention during pregnancy. These include preterm birth, immune system health, heavy metal exposure, and the impact of parenting.
Preterm birth, defined as birth before 37 weeks of gestation, has been linked to autism and other developmental disorders. Research shows that about 7% of preterm babies have autism compared to 1-2% in the general population [5]. Therefore, it's crucial to take all possible steps to reduce the likelihood of preterm birth as part of the strategy for autism prevention during pregnancy. For more information on this, refer to our article on autism symptoms during pregnancy.
A mother's immune system health is another important factor to consider. Problems with a mother’s immune system, certain metabolic conditions, or inflammation during pregnancy may be linked to a higher autism risk for her children [7]. This underscores the importance of maintaining a healthy immune system throughout pregnancy. For an in-depth understanding of this subject, check out our article on autism and prenatal development.
Prenatal and early childhood exposure to heavy metals, like mercury, lead, or arsenic; altered levels of essential metals like zinc or manganese; pesticides; and other contaminants cause concern in relation to autism risk [7]. This highlights the importance of avoiding exposure to such elements during pregnancy. To learn more about this, refer to our article on autism screening during pregnancy.
Certain parenting factors and perinatal conditions have also been linked to a higher risk of Autism Spectrum Disorder (ASD) in offspring. For instance, birth asphyxia was associated with a more than thirteen-fold higher risk of ASD. Breastfeeding difficulties, low responding, harsh or neglectful parenting, and maternal fever during pregnancy were also linked to a higher risk of ASD. This suggests that proper prenatal care and parenting techniques can contribute to autism prevention during pregnancy.
