Abstract:
Objective:To systematically evaluate the correlation between maternal arsenic exposure during pregnancy and congenital heart disease (CHD) in offspring.Methods:Literature search was performed through databases such as PubMed, Web of Science, Embase, China National Knowledge Infrastructure, Wanfang Data Knowledge Service Platform, and VIP.com to include epidemiological literature on association between maternal arsenic exposure during pregnancy and offspring CHD published domestically and internationally. The search was conducted from database establishment until November 2, 2022. Stata MP15 software was used for meta-analysis of binary variables, and I 2 statistics and Q test were used for heterogeneity test, fixed effect model or random effect model was selected based on the test results. Using OR value (95% CI) as the effect evaluation indicator, subgroup analysis was conducted based on CHD subtypes [conotruncal defects (CTD), atrioventricular septal defect (AVSD), total anomalous pulmonary venous return (TAPVR), left ventricular outflow tract obstruction (LVOTO), right ventricular outflow tract obstruction (RVOTO), atrial septal defect (ASD)/ventricular septal defect (VSD), and patent ductus arteriosus (PDA)]. Results:Nine articles were finally included, including two Chinese and seven English articles. Among them, 8 articles had CHD as the outcome, 5 articles had ASD/VSD as the outcome, 4 articles had CTD as the outcome, 3 articles had LVOTO as the outcome, 2 articles had PDA as the outcome, and 1 article had RVOTO as the outcome. An analysis was conducted on 8 articles with CHD as the outcome. After heterogeneity testing, I 2 = 88.5% and P < 0.001, indicating significant heterogeneity. A random effect model was used for meta-analysis, and the combined OR value (95% CI) was 1.51 (1.40 - 1.62). The results of CHD subgroup analysis showed that the combined OR values (95% CI) for ASD/VSD, CTD, LVOTO, PDA, and RVOTO were 1.68 (1.53 - 1.84), 1.64 (1.29 - 2.09), 2.89 (1.82 - 4.61), 1.78 (1.53 - 2.08), and 0.81 (0.64 - 1.03), respectively. Conclusion:Maternal arsenic exposure during pregnancy is associated with development of offspring CHD, including ASD/VSD, CTD, LVOTO, and PDA as the common lesions in offspring CHD.
