Prenatal Diabetes and Obesity: Implications for Autism Spectrum Disorders in Offspring - A Comprehensive Review

Area of Science:

• Neuroscience
• Endocrinology
• Developmental Pediatrics

Background:

• Fetal brain development is crucial for long-term neuropsychological outcomes.
• Intrauterine environmental disruptions, like maternal metabolic disorders, can cause chronic offspring conditions.
• Maternal diabetes, particularly gestational diabetes mellitus, is linked to adverse pregnancy outcomes and neurodevelopmental disorders.

Purpose of the Study:

• To review current research on the impact of prenatal and maternal risk factors on autism spectrum disorder (ASD) development.
• To evaluate the association between maternal pre-pregnancy diabetes, gestational diabetes, and obesity with ASD risk in offspring.

Main Methods:

• Systematic review of recent scientific literature.
• Analysis of studies investigating prenatal environmental factors and maternal health conditions.
• Examination of epidemiological data on hyperglycemia during pregnancy and ASD incidence.

Main Results:

• Hyperglycemia in the intrauterine environment adversely affects fetal brain development.
• Prenatal environmental factors, including maternal diabetes, are implicated in the etiology of autism spectrum disorders.
• Gestational diabetes affects approximately 16.7% of live births globally, with higher prevalence in low- and middle-income countries.

Conclusions:

• Maternal diabetes and obesity are significant risk factors for neurodevelopmental disorders, including ASD.
• Understanding these prenatal risks is critical for early intervention and prevention strategies.
• Further research is needed to elucidate the complex interplay between maternal health and fetal neurodevelopment.
