Abstract:
Objective To explore the relationship between first trimester pregnancy infection and congenital malformation in the cardiovascular system.Methods A hospital-based study was conducted from June 2014 to June 2016.Totally 1618 mothers of infants with cardiovascular system malformation and normal infants were interviewed through a face-to-face questionnaire survey.A propensity score-matched study was conducted to investigate the association between first trimester pregnancy infection and congenital malformation in the cardiovascular system.Results All important covariates were balanced after matching.First trimester pregnancy infection increased the risk of congenital malformation in the cardiovascular system,single congenital malformation in the cardiovascular system and multi-congenital malformation in the cardiovascular system.After matched,the OR values were 1.65 (95％ CI:1.21-2.24;P=0.001),1.50 (95％ CI:1.02 2.20;P=0.037),and 1.90 (95％ CI:1.18-3.06;P=0.008),respectively.Conclusion First trimester pregnancy infection increases the risk of congenital malformation in the cardiovascular system.Avoiding infectious diseases during the first trimester in pregnancy is important in decreasing the incidence of congenital malformation in the cardiovascular system.
