Endocrine disrupting chemicals and growth of children

According to the “environmental obesogen hypothesis”, early-life (including in utero) exposure to endocrine disrupting chemicals (EDCs) may disturb the mechanisms involved in adipogenesis or energy storage, and thus may increase the susceptibility to overweight and obesity. Animal models have shown that exposure to several of these chemicals could induce adipogenesis and mechanisms have been described. Epidemiological studies are crucial to know whether this effect could also be observed in humans. The authors aimed at summarising the literature in epidemiology on the relationship between EDCs exposure and child’s growth. Overall, epidemiological studies suggest that pre- and/or early postnatal exposure to some EDCs may increase the risk of overweight or obesity during childhood. In that review, the author present some limitations of these studies, mainly in exposure assessment, that currently prevent to conclude about causality. Recent advances in epidemiology should bring further knowledge.
