| Summary: | Exposure to specific alkali and alkaline earth elements(AEs/AEEs) has been reported that are linked to an increased risk of spontaneous abortion. However, the direct evidence of exposure in the uterus are absent. Therefore, we collected chorionic villi after spontaneous abortion or induced abortion in Peking University Third Hospital. The concentrations of six alkali and alkaline earth elements in chorionic villi were measured using inductively coupled plasma mass spectrometry (ICP-MS). Through using logistic regression, Bayesian kernel machine regression (BKMR) and Weighted quantile sum regression (WQS) model, we assessed single and mixed exposure effects of alkali and alkaline earth elements on spontaneous abortion. In terms of the individual effect, high concentration group of barium (Ba) increased the risk of spontaneous abortion by 150 % (95 % CI: 1.38–4.51), whereas rubidium (Rb), cesium (Cs) and Magnesium (Mg) all clearly demonstrated dose dependency in reducing the incidence of spontaneous abortion. The BKMR model demonstrated that as the mixed exposure percentile increased, the likelihood of spontaneous abortion decreased almost linearly. For every quartile increasing in the WQS index, the risk of spontaneous abortion decreased (OR: 0.21, 95 % CI: 0.13–0.33), with Mg and Rb having the highest weights at 0.587 and 0.367, respectively. According to our findings, there were negative dose-response relationships between Mg and Rb levels and risk for spontaneous abortion, but exposure to higher concentration of Ba in the chorionic villi was positively associated with the risk of it. |
