Influences of maternal nutritional status on vascular function in the offspring

Area of Science:

• Cardiovascular Science
• Developmental Biology
• Nutritional Science

Background:

• Fetal growth restriction and low birthweight are linked to later-life ischemic heart disease and hypertension.
• Maternal nutritional excess during pregnancy is increasingly recognized as a factor initiating cardiovascular risk in offspring.
• Early life vascular disorders may play a role in the development of atherosclerosis and hypertension.

Purpose of the Study:

• To review studies in humans and animals investigating the role of vascular disorders in atherosclerosis and hypertension.
• To examine the impact of early life nutritional deprivation and excess on vascular health.
• To explore the mechanisms linking early nutrition to later cardiovascular disease.

Main Methods:

• Literature review of human and animal studies.
• Analysis of research on maternal nutrition and offspring cardiovascular outcomes.
• Synthesis of findings on endothelial cell function and arterial stiffness.

Main Results:

• Maternal undernutrition and overnutrition are associated with arterial endothelial cell malfunction in offspring.
• Increased stiffness of large arteries is frequently observed, potentially contributing to systolic hypertension.
• Evidence suggests early nutritional imbalance may impair vascular angiogenesis, leading to rarefaction and increased peripheral resistance.

Conclusions:

• Early life nutritional status significantly influences vascular development and function.
• Vascular endothelial dysfunction and arterial stiffness are key pathways linking early nutrition to adult cardiovascular disease.
• Further research is needed on the impact of nutritional imbalance on vascular angiogenesis and peripheral resistance.
