简要总结
Gestational diabetes mellitus (GDM) refers to the abnormal glucose metabolism index of pregnant women during pregnancy. At present, about 15% of pregnant women will develop GDM in the second and third trimester, which seriously affects the health of the pregnant woman and the fetus. However, the etiology of GDM remains unclear. Various pollutants in the environment may have a potential impact on pregnant women and fetuses. For example, previous studies have shown that exposure to atmospheric pollutants nitric oxide and organochlorine pesticides are associated with GDM. At present, we plan to further investigate the correlation between environmental pollutants and GDM.

结局指标
主要结局
Environmental contaminants 2
时间窗: Third trimester (after 28 gestational weeks)
The concentrations of environmental pollutants, such as organochlorine pesticides, polychlorinated biphenyls, polycyclic aromatic hydrocarbons, polybrominated diphenyl ethers and metallic elements, in serum and urine were analyzed by gas chromatochromatograms and mass spectrometry (GC-MS/MS). Specimens were collected during the third trimester.
Environmental contaminants 1
时间窗: First trimester (9-14 gestational weeks)
The concentrations of environmental pollutants, such as organochlorine pesticides, polychlorinated biphenyls, polycyclic aromatic hydrocarbons, polybrominated diphenyl ethers and metallic elements, in serum and urine were analyzed by gas chromatochromatograms and mass spectrometry (GC-MS/MS). Specimens were collected during the first trimester and tested when classified in the GDM or control group
