Research has identified several pregnancy-related factors that may influence autism risk. Understanding these factors helps expectant parents make informed health decisions, though it is important to remember that most of these factors involve small increases in relative risk.

Identified Pregnancy-Related Risk Factors

• Advanced parental age: Both maternal and paternal age over 35 are associated with slightly increased risk
• Gestational diabetes: May be associated with modestly increased risk
• Prenatal medication use: Certain medications, particularly valproic acid, have established links
• Preterm birth: Babies born very early have higher rates of developmental conditions including autism
• Short interpregnancy intervals: Pregnancies spaced less than 12 months apart may carry slightly higher risk

Keeping Perspective

Most children exposed to these risk factors do not develop autism. The absolute risk remains low even when relative risk is elevated. Genetics account for the majority of autism risk, and most genetic factors are not modifiable.

What Expectant Parents Can Do

Maintain regular prenatal care, discuss any medications with your OB-GYN, manage health conditions proactively, and take recommended prenatal vitamins. These steps support healthy development overall.
