Abstract:
Objective Intrahepatic cholestasis during pregnancy (ICP) and its relation to incidence of preterm birth (PTB) were under study.Methods A prospective cohort study was carried out that including all the hospitalized pregnant women with live singleton births,from January 2014 to March 2015 in Anqing Municipal Hospitals.Informed consent was followed in every pregnant woman with related demographic information collected through questionnaire and hospital electronic medical record system.Both univariate and multi-variate statistical methods were used to analyze the relations between ICP and incidence of PTB.Results A total of 2 758 pregnant women were included in this study.The incidence proportions of ICP and PTB appeared as 7.25％ and 16.28％ respectively.Results from the logistic regression analysis showed that ICP increased the risk of both overall PTB (RR=2.33,95％CI:1.67-3.25) and medically indicated PTB (RR=8.46,95％CI:5.45-13.12),but not the spontaneous PTB (RR=0.94,95％CI:0.57-1.54).Conclusion ICP seemed to have increased the risk on medically indicated PTB but not the spontaneous PTB.
