Doha, July 21 (QNA) - Two studies published by researchers from Sidra Medicine's Precision Nutrition Laboratory show how maternal nutrition shapes fetal development through biological mechanisms that regulate how genes are expressed without altering DNA itself. The findings reinforce growing evidence that nutrition during pregnancy plays a fundamental role in determining a child's health before birth and may influence disease risk later in life.
Together, the studies form part of Sidra Medicine's broader Precision Nutrition initiative, the research-driven institutional strategy that combines research, clinical expertise, and personalized care to develop evidence-based nutritional strategies that improve pregnancy outcomes and support healthier future generations. 
The first study examined the relationship between maternal nutrition and preterm birth. Researchers found that women who delivered prematurely consumed significantly lower amounts of protein, vitamins, and essential minerals than mothers who delivered full-term pregnancies. The study further identified distinct epigenetic changes in both the placenta and umbilical cord blood, particularly in genes involved in fetal development and immune function. These findings suggest that inadequate protein intake during pregnancy may contribute to biological changes associated with an increased risk of preterm birth and could eventually support earlier identification of at-risk pregnancies.
The second study, meanwhile, focused on gestational diabetes mellitus (GDM), one of the most common pregnancy complications worldwide. Researchers found that mothers diagnosed with gestational diabetes consumed significantly higher amounts of saturated fat while having lower levels of vitamin D and folate compared with healthy pregnancies.
The research also revealed widespread epigenetic changes affecting genes involved in insulin regulation and glucose metabolism, including the gene ZFP57, suggesting that maternal dietary patterns may influence a child's future metabolic health and susceptibility to chronic diseases such as type 2 diabetes. 
Clinically, these findings underscore the potential value of early nutritional assessment and targeted dietary intervention in pregnant women at risk of gestational diabetes to help improve maternal outcomes and support long-term metabolic health in their children.           
Sidra Medicine said that it was also investigating how the type and quality of dietary fats consumed during pregnancy may influence early brain development and the future risk of neurodevelopmental conditions such as autism spectrum disorder and attention deficit hyperactivity disorder. (QNA)
