Maternal and child obesity: the causal link

Area of Science:

• Reproductive Health
• Pediatric Health
• Metabolic Disorders

Background:

• Maternal pre-pregnancy weight and gestational weight gain are linked to offspring obesity and cardiometabolic risks.
• Intrauterine exposure to an obese environment influences offspring's appetite, metabolism, and activity levels.
• Shared genetics and behaviors partially mediate these associations.

Purpose of the Study:

• To summarize evidence on maternal weight and intrauterine programming of offspring obesity.
• To highlight the public health importance of interrupting the cycle of obesity transmission.
• To underscore the economic benefits of successful interventions.

Main Methods:

• Review of epidemiologic studies in humans.
• Analysis of experimental data from animal models.
• Synthesis of evidence on intrauterine programming mechanisms.

Main Results:

• Higher maternal weight and gestational weight gain are associated with increased offspring obesity risk.
• Intrauterine environment significantly influences offspring's long-term metabolic health.
• Evidence supports programming effects on appetite, metabolism, and activity.

Conclusions:

• Interventions to mitigate maternal obesity are crucial for preventing intergenerational obesity.
• Addressing maternal weight can improve child, maternal, and future pregnancy outcomes.
• Preventing offspring obesity has significant public health and economic implications.
