ABSTRACT

Objective To explore the relationship of four kinds of lifestyle factors,namely,prenatal passive smoking,hair dyeing or perming,exposure to noise,living in a house renovated in the past one year,with congenital heart disease.Methods A hospital-based case-control study was conducted.Totally 270 mothers in the case group and 1633 mothers in the control group were interviewed through a face-to-face questionnaire survey.A generalized linear model was employed to investigate the association between congenital heart disease and prenatal lifestyle factors.Results Both in Model 1 and Model 2,prenatal hair dyeing or perming had no association with congenital heart disease.On the other hand,prenatal passive smoking,exposure to noise and living in a house renovated in the past one year all increased the risk of congenital heart disease.After adjustment for all confounders,the OR values were 1.771 (95％ CI1.079-2.909),2.079 (95％ CI1.310-3.298),and 2.494 (95％ CI1.511-4.116),respectively.Conclusion Prenatal passive smoking,exposure to noise and living in a house renovated in the past one year are the risk factors for congenital heart disease.It is very important to avoid such factors during pre-pregnancy and pregnancy.
