- Abstract: Objective: To compare the exposure of commonly used electrical appliances by mothers in early pregnancy so as to explore the association between electromagnetic exposure in daily life and congenital heart disease (CHD). Methods: We conducted a hospital-based case-control study. Totally 274 mothers in the case group and 548 mothers in the control group were interviewed through a face-to-face questionnaire. The multivariate logistic regression was applied to analyze the association between CHD and electromagnetic exposure. Results: After adjustment for the confounding factors, in early pregnancy, mothers' exposure to cell phones (OR=0.20, 95% CI: 0.07-0.58), induction cookers (OR=1.97, 95% CI: 1.31-2.96) and microwave ovens (OR=2.90, 95% CI: 1.41-5.97), and wearing radiation suits (OR=0.58, 95% CI: 0.39-0.86) were related to the occurrence of CHD. In the subgroup analysis, compared with the non-radiation suit, microwave oven exposure of the mothers in radiation suits did not significantly affect CHD in early pregnancy, but exposure to induction cookers could increase the risk of CHD in both subgroups. Conclusion: Mothers' exposure to microwave ovens and induction cookers in early pregnancy may increase the risk of CHD in the offspring. The exposure should be decreased and avoided as much as possible.
