Prenatal food supplements linked to better birth outcomes in global study

By AI, Created 3:45 PM UTC, May 19, 2026, /AGP/ – George Mason-led research across Africa and South Asia found that balanced energy and protein supplements during pregnancy were tied to higher birth weights and fewer high-risk newborns. The study suggests food-based nutrition support may be a scalable way to improve fetal growth in low- and middle-income countries.

Why it matters: - Maternal malnutrition raises the risk of infant death, illness and developmental delays. - Food-based prenatal supplements may offer a practical way to improve fetal growth where daily nutrition is unstable. - The findings could help existing maternal health programs reach more pregnant people in low- and middle-income countries.

What happened: - A George Mason University-led study found that balanced energy and protein, or BEP, supplements were associated with healthier birth outcomes. - The research was led by epidemiologist Dongqing Wang of the George Mason University College of Public Health. - The findings were published in PLOS Medicine. - The analysis drew on eight clinical trials in Africa and South Asia. - The trials included randomized controlled studies in Nepal, The Gambia, Pakistan and other low- and middle-income settings.

The details: - BEP supplements are food-based products, including beverages and nutrient-dense pastes, designed to increase calorie and protein intake during pregnancy. - The study combined individual-level data from the trials and compared pregnant people who received BEP supplements with those who did not. - BEP supplementation was linked to higher birth weights. - BEP supplementation was also linked to a lower risk of low birth weight and babies small for gestational age. - The effect was especially notable for babies small for gestational age, a group with elevated risk of neonatal mortality. - Benefits were stronger when supplementation started earlier in pregnancy, especially before 20 weeks. - Wang said early action matters in settings where pregnant women cannot access enough calories and protein. - Wang is also conducting follow-up research in Ethiopia on the cost-effectiveness of different BEP approaches. - The research involved collaborators from Harvard T.H. Chan School of Public Health, the Food and Agriculture Organization of the United Nations, Aga Khan University and partners across Europe, South Asia and Africa.

Between the lines: - The study adds to evidence that calorie and protein support during pregnancy may matter more for birth outcomes than micronutrient-only interventions in some settings. - If BEP programs can be delivered through existing maternal health systems, the intervention may be easier to scale than more specialized nutrition programs. - The stronger results from earlier supplementation suggest timing could be as important as the supplement itself.

What’s next: - Wang’s Ethiopia research will examine which BEP delivery approaches are most cost-effective. - The new findings may influence how maternal nutrition programs are designed in low-resource settings. - More work is likely needed to determine where BEP supplementation produces the biggest health gains and how best to expand access.
