PRIYA Trial Highlights Impact of Vitamin B12 on Long-term Health and Epigenetics in Infants
The Pune Rural Intervention in Young Adolescents (PRIYA) trial has established a significant link between maternal Vitamin B12 levels and the long-term health of offspring. Research indicates that B12 acts as a 'regulator of regulators,' influencing gene expression through epigenetic modifications like DNA methylation. Deficiency during pregnancy is linked to neural tube defects and poor fetal growth. The study suggests that B12 supplementation in adolescents and pregnant women could prevent 'diabesity' (diabetes and obesity) in future generations. Experts recommend incorporating B12 into national health policies to improve nutritional status and human capital development.
Key Points
- Vitamin B12 deficiency is widespread in the Indian population, particularly among vegetarians.
- The PRIYA trial found that B12 supplementation in adolescents improved birth outcomes for their future children.
- B12 influences enzymes called methylases, which add methyl groups to DNA to regulate gene expression.
- Low B12 and high folate levels in pregnant women are associated with a higher risk of insulin resistance in children.
Exam Facts
- The PRIYA trial stands for Pune Rural Intervention in Young Adolescents.
- The recommended daily allowance (RDA) of Vitamin B12 mentioned is 2 micrograms.
- B12 is essential for the formation of blood cells and the functioning of nerve cells.
