Abstract:
OBJECTIVE:To explore the relation between environmental factors and the occurrence of congenital heart disease (CHD).
METHODS:A hospital-based case-control study was conducted. Mothers of 123 patients with congenital heart disease and 246 normal newborns were interviewed with standardized questionnaires. Chi-square test and logistic regression models were performed to analyze the influencing factors.
RESULTS:As shown in multivariable logistic model, gravida with occupational exposure (OR=4.10), or gravida with chronic diseases during progestational pregnancy (OR=5.95), gravida with abnormal childbearing history (OR=6.27), and gravida catching a cold in the early stage of pregnancy (OR=2.07) would increase the risk of CHD. On the contrary, eating meat, egg (OR=0.18) and milk (OR=0.23), and taking multivitamin and microelement (OR=0.35) during the pregnancy reduced the risk of CHD.
CONCLUSION:The risk of the offspring developing CHD is associated with gravida's exposure to many environmental factors during pregnancy. It is time to strengthen the intervention measures to reduce the occurrence of CHD.
