ObjectiveWe aimed to explore maternal and paternal risk factors with risk of congenital heart disease in infants.MethodsA total of 125 congenital heart disease (CHD) infants and 125 controls were included in Heping Hospital Affiliated to Changzhi Medical College, Shanxi, China. Subjects were diagnosed between Jan 1, 2016 and Dec 31, 2021 in the present study. All the characteristics were collected with questionnaire by face-to-face interview, including maternal and paternal risk factors. Conditional logistic regression was conducted to explore the risk factors with risk of congenital heart disease in infants.ResultsFor maternal risk factors, we found that age, number of pregnancies, systolic blood pressure (SBP), diastolic blood pressure (DBP), and body mass index (BMI) were risk factors for CHD infants, and the ORs (95%CIs) were 1.15 (1.06-1.23) for age, 1.13 (1.02-1.29) for SBP, 1.06 (1.02-1.18) for DBP, 1.22 (1.16-1.31) for BMI. Compared with one pregnancy, the ORs (95%CIs) were 1.17 (1.05-1.29) for two pregnancies and 1.25 (1.16-1.47) for more pregnancies. For paternal risk factors, we found that age (OR = 1.07, 95%CI = 1.01-1.19), smoking (OR = 1.11, 95%CI = 1.03-1.27), drinking (OR = 1.04, 95%CI = 1.02-1.19), and BMI (OR = 1.15, 95%CI = 1.03-1.28) were risk factors for CHD infants.ConclusionWe found that age, number of pregnancies, SBP, DBP, and BMI are maternal risk factors for CHD infants. And age, smoking, drinking, and BMI are paternal risk factors for CHD infants.© 2023. The Author(s), under exclusive licence to Royal Academy of Medicine in Ireland.
