Key Environmental Factors Affecting Fetal Development andDiabetes Programming

Numerous studies have identified specific environmental agents that, when n meegetered in utero, are associated with a higher incidence of obesity, insulin resistance, and type 2 diabetets in childhood and d diulthood. These factors are pervasive in modern environments, making their ir identification and compation a public hearth priority.

Endokryno- Disprupting Chemicals (EDC)

Endocrinen- distorting chemicals are synthetic or natural compounds that interfere wigh contribute syntetis, secretion, transport, binding, or action. Because fetal development is exquisitely sensitivy to o contacal cues, EDCs can profoundly alter metabolung programming. Key EDCs linked to offspring diabetetes risk include:
