Birth, Development, and Health

The conditions a fetus experiences in the womb — including nutritional adequacy, hormonal exposure, and oxygen supply — can permanently alter how organs develop and how the body regulates metabolism, blood pressure, and stress responses decades later. Researchers working on developmental origins of health and disease have found that low birth weight, followed by rapid catch-up growth in infancy, is linked to elevated risks of hypertension, insulin resistance, and metabolic syndrome in adulthood, with epigenetic modifications serving as a likely molecular bridge between early experience and later physiology. Much of the current work centers on understanding precisely how glucocorticoid signaling and in utero nutrient restriction reprogram gene expression in ways that persist across the lifespan. Open questions include whether these epigenetic marks can be reversed through early intervention, and how to identify at birth which individuals carry the greatest long-term disease risk.
