Developmental Programming in Animal Models: Critical Evidence of Current Environmental Negative Changes

Area of Science:

• Reproductive Health
• Developmental Biology
• Public Health

Background:

• The Developmental Origins of Health and Disease (DOHaD) framework links early-life exposures to adult health outcomes.
• High rates of obesity and metabolic diseases are prevalent in vulnerable populations, including children and women of reproductive age.
• Maternal conditions during pregnancy and lactation, alongside adult lifestyle factors, contribute to metabolic disease development.

Purpose of the Study:

• To review the significance of DOHaD research.
• To discuss established DOHaD programming studies.
• To explore emerging environmental and lifestyle factors influencing offspring development.

Main Methods:

• Literature review of DOHaD studies.
• Analysis of classical programming research.
• Examination of recent environmental and lifestyle influences on development.

Main Results:

• Early life events, including maternal health and environmental exposures, significantly influence developmental programming.
• Traditional factors like malnutrition and smoking, alongside new factors like pollution and stress, impact offspring health.
• Pregnancy and lactation are critical windows where offspring are vulnerable to programming mechanisms.

Conclusions:

• DOHaD research is vital for understanding the roots of adult diseases.
• Emerging environmental and lifestyle factors represent new critical areas for DOHaD research.
• Interventions targeting early life are essential for improving long-term public health outcomes.
