Developmental undernutrition, offspring obesity and type 2 diabetes

Area of Science:

• Endocrinology
• Public Health
• Developmental Biology

Background:

• The Developmental Origins of Health and Disease (DOHaD) paradigm suggests early-life exposures influence long-term health.
• Metabolic dysregulation, obesity, and diabetes are significant global health challenges.
• Understanding the interplay between early development and later disease is crucial for prevention.

Purpose of the Study:

• To review evidence supporting the DOHaD paradigm concerning metabolic diseases.
• To explore the relationship between early-life nutrition, growth patterns, and the risk of obesity and diabetes.
• To emphasize the importance of intergenerational prevention strategies for non-communicable diseases.

Main Methods:

• Review of prospective studies on growth patterns from birth to adulthood.
• Analysis of historical studies on gestational and early-life famine exposure.
• Examination of findings from nutrition intervention studies.

Main Results:

• Evidence suggests a link between early-life undernutrition and later obesity.
• This combination is associated with an increased risk of developing diabetes.
• While much remains unknown, the DOHaD hypothesis is increasingly supported by scientific data.

Conclusions:

• A mismatch in environmental conditions from conception through early life to adulthood can lead to metabolic dysregulation.
• Early-life undernutrition followed by later obesity significantly elevates diabetes risk.
• Public health initiatives for intergenerational (primordial) prevention of diabetes and other non-communicable diseases are essential.
