This review systematically examines the associations between prenatal trace elements and toxic metals exposure and childhood growth and development, with a particular focus on changes in longitudinal growth trajectories. A comprehensive search was conducted across four electronic databases, and 24 studies were included in the final analysis. Maternal exposure to elevated concentrations of trace elements such as vanadium, chromium and manganese has been linked to physical growth restriction in children. In contrast, prenatal exposure to other trace elements, including zinc, calcium and copper, appears to have positive effects on child growth and development. The effects of lithium exposure during pregnancy have not been fully determined. Moreover, children's growth parameters and trajectories are generally negatively affected by exposure to toxic metals, such as lead, cadmium and mercury.
