Preconception Risk Factors for Autism Spectrum Disorder - A Pilot Study

Area of Science:

• Neurodevelopmental Disorders
• Genetics and Epidemiology
• Reproductive Health

Background:

• Autism spectrum disorder (ASD) is a complex neurodevelopmental condition with multifactorial causes.
• Preconception risk factors for ASD remain inadequately understood, necessitating further investigation.

Purpose of the Study:

• To identify significant preconception risk factors associated with the development of autism spectrum disorder (ASD).

Main Methods:

• A survey was conducted among parents of children diagnosed with ASD and healthy controls.
• Thirteen potential risk factors were analyzed, including maternal health history, conception methods, and family medical history.
• Statistical analysis was performed to determine significant associations between factors and ASD development.

Main Results:

• Maternal history of mental illness (35.54% vs. 16.0%, p = 0.0002) was significantly associated with increased ASD risk.
• Maternal thyroid disease (16.67% vs. 5.0%, p = 0.009) showed a statistically significant link to higher ASD incidence.
• Maternal oral contraceptive use (46.28% vs. 29.0%, p = 0.01) was also found to be a significant risk factor for ASD.

Conclusions:

• Maternal mental illness, thyroid disease, and oral contraceptive use are identified as significant preconception risk factors for autism spectrum disorder.
• Children born to mothers with these risk factors warrant close monitoring for early signs of ASD.
• Further research is recommended to elucidate the causal relationship between oral contraceptive use and offspring neurodevelopment.
