[Programming nutritional and metabolic disorders: the diabetic environment during gestation]

Area of Science:

• Developmental biology
• Public health
• Epigenetics

Background:

• Rising rates of obesity, metabolic disorders, and cardiovascular diseases (CVD) are a global concern.
• Cardiovascular disease risk factors are increasingly identified in infancy, often programmed during fetal development.
• The concept of 'fetal programming' links early-life environment to long-term health outcomes.

Purpose of the Study:

• To explore the concept of fetal programming and its role in metabolic syndrome and CVD.
• To highlight the impact of both poor and excess fetal growth on adult disease risk.
• To emphasize the contribution of epigenetic mechanisms to intergenerational health effects.

Main Methods:

• Review of existing literature on fetal programming.
• Analysis of studies linking early-life environment to adult metabolic and cardiovascular health.
• Examination of epigenetic mechanisms involved in developmental programming.

Main Results:

• Both restricted and excessive fetal growth, such as in pregnancies with maternal diabetes, are associated with increased adult risks.
• Metabolic syndrome, a cluster of CVD risk factors, is increasingly prevalent in youth, particularly with obesity.
• Altered intrauterine environments can lead to adaptations that are transmitted across generations, contributing to adult disease burden.

Conclusions:

• Fetal programming, influenced by the intrauterine environment and epigenetic modifications, plays a critical role in lifelong and intergenerational health.
• Preventive public health programs targeting early life are essential to mitigate the long-term consequences of fetal programming.
• Understanding these mechanisms is crucial for addressing the increasing prevalence of metabolic disorders and cardiovascular diseases.
