Fetal malnutrition and long-term outcomes

Nestle Nutrition Institute Workshop Series
|July 27, 2013
Summary
Optimal fetal nutrition is crucial for long-term health, influencing human capital and disease risk. Interventions during pregnancy may offer benefits, but preconception nutrition might be key for developmental programming.
Area of Science:
- Developmental biology
- Epidemiology
- Nutritional science
Background:
- Birthweight is linked to numerous adverse health outcomes and diseases later in life.
- The developmental origins of health and disease (DOHaD) hypothesis suggests fetal nutrition permanently impacts adult health.
- Maternal nutrition during pregnancy influences offspring development and long-term health.
Purpose of the Study:
- To explore the impact of fetal nutrition on long-term health outcomes.
- To investigate the potential of nutritional interventions for disease prevention.
- To understand the mechanisms of developmental programming.
Main Methods:
- Review of epidemiological studies on birthweight and health outcomes.
- Examination of animal studies on maternal nutrition and offspring development.
- Analysis of randomized nutritional interventions during pregnancy.
Main Results:
- Lower birthweight is associated with poorer human capital and increased disease risk.
- Higher birthweight is linked to increased cancer and obesity risks.
- Nutritional interventions in pregnancy show weak evidence of benefit; preconception nutrition may be important.
Conclusions:
- Optimal fetal nutrition is vital for preventing chronic diseases and improving health outcomes.
- Epigenetic mechanisms may underlie developmental programming by nutrition.
- Nutritional strategies may need to commence before conception for maximum impact.

01:07Teratogenicity
The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
01:20Inborn Errors of Metabolism
Phenylketonuria (PKU) is a protein metabolism disorder characterized by high blood levels of the amino acid phenylalanine. This results from a mutation in the gene responsible for phenylalanine hydroxylase, an enzyme that converts phenylalanine into tyrosine. When this enzyme is deficient, phenylalanine builds up in the blood, leading to symptoms such as vomiting, rashes, seizures, growth deficiency, and severe mental retardation. An early diagnosis and a diet restricting phenylalanine intake...
01:14Fetal Circulation
Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...

01:20Pathophysiology of Diabetes
Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility, suggesting a...

01:21Overview of Protein Metabolism
Proteins are broken down into amino acids during digestion. Unlike fats and carbohydrates, which are stored for later use, proteins are not. Instead, amino acids are either used to produce ATP through oxidation or contribute to the creation of new proteins for the growth and repair of the body. Any surplus amino acids from the diet are converted into glucose or triglycerides rather than excreted.
Amino acids play various roles in the body once they are absorbed into cells. They are restructured...

01:27Parentral Nutrition: Centeral and Peripheral Parental Nutrition
Parenteral Nutrition (PN) delivers essential nutrients directly into the bloodstream, bypassing the digestive system. It is commonly used for individuals with severe digestive disorders or conditions that prevent normal nutrient absorption.
PN can be administered through two primary routes:
1. Central Parenteral Nutrition (CPN):
CPN involves delivering a high concentration of nutrients through a large vein. This is typically achieved using a Peripherally Inserted Central Catheter (PICC) or,...
