Sidra Medicine, a part of Qatar Foundation, is advancing maternal and child healthcare through innovative research in precision nutrition. Recent studies indicate that a mother's dietary choices during pregnancy can significantly affect both pregnancy outcomes and the long-term health of her child.

Researchers at Sidra Medicine's Precision Nutrition Laboratory have released two new studies highlighting the impact of maternal nutrition on fetal development through epigenetic changes—mechanisms that modify gene expression without altering DNA. These findings support the view that nutrition during pregnancy is crucial in shaping a child's health before birth, potentially influencing disease risk later in life.
Dr. Annalisa Terranegra, head of the Precision Nutrition Laboratory, stated that nutrition serves as a powerful determinant of health that begins before birth. The research indicates that a mother's diet can create measurable biological signatures affecting fetal development and could guide personalized nutritional recommendations to prevent pregnancy complications, aiming for a healthier start for every child.
The first study, published in npj Science of Food, focused on the link between maternal nutrition and preterm birth. It found that women who delivered prematurely had significantly lower intakes of protein, vitamins, and essential minerals compared to those with full-term pregnancies. This study identified notable epigenetic changes in the placenta and umbilical cord blood, particularly in genes related to fetal development and immune function, suggesting that insufficient protein intake may increase the risk of preterm birth and aid in early identification of at-risk pregnancies.
The second study, appearing in Molecular Nutrition & Food Research, examined gestational diabetes mellitus, a prevalent pregnancy complication. It revealed that mothers with gestational diabetes consumed higher amounts of saturated fats while having lower levels of vitamin D and folate compared to those with healthy pregnancies. The research uncovered widespread epigenetic changes in genes responsible for insulin regulation and glucose metabolism, indicating that maternal dietary patterns may affect a child's future metabolic health and risk for chronic diseases, including type 2 diabetes.
These findings emphasize the importance of early nutritional evaluation and targeted dietary interventions for pregnant women at risk of gestational diabetes to improve maternal outcomes and support the long-term metabolic health of their children. Additionally, Sidra Medicine is investigating how the type and quality of dietary fats consumed during pregnancy may affect early brain development and the prevalence of neurodevelopmental conditions, such as autism spectrum disorder and attention deficit hyperactivity disorder.
Dr. Ibrahim Mamoun Ibrahim, senior attending physician in Endocrinology and lead for Diabetes in Pregnancy at Sidra Medicine, remarked that while gestational diabetes is common, it is also one of the most preventable complications when women receive the appropriate support. This research reinforces the notion that nutrition is not merely lifestyle advice, but a critical component of medical care during pregnancy.
