Vitamin A levels and infant birth weight research

Overview

A Norwegian study has identified a correlation between low vitamin A levels in pregnant women during the final stages of pregnancy and significantly higher birth weights in their infants.

Research involving 723 women with normal pregnancies found that 43 percent had low vitamin A levels. While the study notes a connection, researchers stated they cannot definitively conclude that low vitamin A causes high birth weight. Infants weighing over 4 kilograms are classified as having high birth weight, a condition that may increase the likelihood of obesity later in life.

Researcher Kamilla Stunes noted that while extreme vitamin A deficiency can lead to blindness and excessive intake can cause fetal malformations, such extremes are rare in Norway. She emphasized that following national dietary guidelines typically ensures sufficient intake.

    Vitamin D levels linked to reduced preterm birth risk

    A study of over 15,000 pregnancies indicates that sufficient vitamin D levels are associated with a lower risk of preterm birth, particularly reducing the likelihood of very preterm deliveries.
