Maternal Obesity in Pregnancy: Risk Factor for Neurodevelopmental Outcomes in Offspring

Area of Science:

• Neuroscience
• Developmental Biology
• Public Health

Background:

• Obesity is a global epidemic characterized by excessive fat accumulation and energy imbalance.
• Maternal obesity rates are rising, posing significant risks to both mother and child.
• Maternal obesity during pregnancy can lead to acute and chronic health issues in offspring, including metabolic, hormonal, neurodevelopmental, and psychiatric disorders.

Purpose of the Study:

• To review the impact of maternal obesity on offspring neurodevelopment.
• To explore the mechanisms by which maternal obesity affects fetal brain development.
• To understand the link between maternal obesity and offspring behavioral disorders.

Main Methods:

• Literature review focusing on studies examining maternal obesity and offspring neurodevelopment.
• Analysis of research on the Developmental Origins of Health and Disease (DOHaD) theory in the context of maternal obesity.
• Synthesis of findings on the effects of maternal obesity on fetal brain structure, function, and neuroinflammation.

Main Results:

• Maternal obesity can reprogram fetal immune, metabolic, endocrine, and neurological systems.
• Prenatal exposure to maternal obesity influences offspring metabolism and mental health.
• Specific effects include alterations in brain neurodevelopment, neural circuits, synapses, glial cells, and neuroinflammation, contributing to behavioral disorders.

Conclusions:

• Maternal obesity is a critical factor influencing offspring neurodevelopment and long-term health.
• The DOHaD theory provides a framework for understanding these effects.
• Further research is needed to mitigate the adverse neurodevelopmental consequences of maternal obesity.
