The study titled "In Utero Exposure to Extra Vitamin D from Food Fortification and the Risk of Subsequent Development of Gestational Diabetes: The D-TECT Study" by Amélie Keller et al. examines the relationship between prenatal exposure to extra vitamin D from food fortification and the risk of developing gestational diabetes mellitus (GDM). Utilizing data from Danish national health registers, the study finds that women exposed to vitamin D during fetal life exhibited a lower tendency to develop GDM compared to unexposed women (OR 0.87, 95% CI 0.74–1.02, P = 0.08). Notably, spring-born women showed a significant reduction in GDM risk when exposed to vitamin D (OR 0.68, 95% CI 0.50–0.94, P = 0.02). These findings suggest that prenatal vitamin D exposure may offer protective benefits against GDM, particularly for women born in spring.
