Developmental origins of obesity: programmed adipogenesis

Area of Science:

• Reproductive Medicine
• Pediatrics
• Public Health

Background:

• The rising prevalence of metabolic syndrome, including obesity and gestational diabetes mellitus (GDM), poses a significant public health challenge.
• Prenatal and infant environmental factors, especially nutrition, are increasingly recognized as key influences on adult obesity risk, forming the basis of developmental programming.
• Both low birth weight with catch-up growth and exposure to maternal obesity (with or without GDM) or high birth weight are linked to increased risks of childhood and adult obesity.

Purpose of the Study:

• To review the influence of prenatal and early life exposures on the risk of adult obesity.
• To highlight the role of developmental programming in the context of metabolic syndrome.
• To identify opportunities for prenatal care interventions to prevent or mitigate childhood and adult obesity.

Main Methods:

• Review of epidemiological findings in humans.
• Analysis of animal models elucidating programming mechanisms.
• Examination of the impact of maternal obesity, GDM, and birth weight on long-term obesity risk.

Main Results:

• Animal studies have successfully replicated human epidemiological data on developmental programming.
• Identified programming mechanisms include alterations in organ development, cellular signaling, and epigenetic modifications.
• Maternal obesity, GDM, and birth weight are significant risk factors for offspring obesity.

Conclusions:

• Prenatal care is evolving to address long-term health outcomes beyond neonatal health.
• Interventions during pregnancy and infancy hold promise for preventing adult obesity.
• Further guidelines are needed to integrate optimal pregnancy nutrition, weight management, GDM care, and infant feeding strategies to combat the obesity epidemic.
