Serum levels of trace elements in children born after assisted reproductive technology

This study was designed to investigate whether ART children have differences in the levels of trace elements compared with naturally conceived children.MethodsThis study included those ART children and controls aged 1 to 12 years assessed with a follow-up protocol. Serum levels of the trace elements zinc, copper, iron, calcium, magnesium and lead were determined and analyzed.ResultsThere were no significant differences in age, gender or body weight between the ART and control groups. There were no significant differences in the rates of deficiency or excess of trace elements between the two groups. Serum lead levels in children born via ART were significantly higher than those in the controls, whereas the levels of zinc and iron were significantly decreased in the ART group, although these levels were still within the normal ranges.DiscussionThese results indicate the need to monitor the blood levels of zinc, iron and lead in ART children aged 1–6 years old. These findings contribute to our understanding on the long-term safety of ART and may facilitate screening for potential diseases related to trace elements.
