Objective:To investigate the current situation and associated factors of interpregnancy interval(IPI)among multiparous women in Shanghai during the transition period of fertility policy,so as to provide reference for further promotion and improvement for reproductive policy and social services.Methods:A total of 657 multiparous women who had made registration and received routine antenatal care in a tertiary maternity hospital of Shanghai were surveyed by questionnaires.The generalized linear model was used to analyze associated factors of IPI.Results:The mean interpregnancy interval among multiparous women was 5.97 years,with a median of 5.13 years.Older age,history of abortion,and history of cesarean delivery were significantly associated with longer IPI.The education level of postgraduate or undergraduate,more than twice parities,unplanned pregnancy,previous childbirth comorbidity or complications,reporting moderate or poor health status,nanny or childcare institution taking on most childcare for current children,parents or parents-in-law taking on most household chores,and unemployment were significantly associated with shorter IPI(P<0.05).Conclusion:Interpregnancy interval of multiparous women in Shanghai during the transition period of fertility policy is at a relatively long level.The interpregnancy interval is associated with their personal,health,family and work factors.
