[Complications and related determinants in 13669 pregnant women]

To investigate pregnancy complications and related determinants, and provide scientific evidence for maternal health care.

A total of 13669 pregnant women who planned to deliver in the hospital were randomly identified and surveyed by questionnaire. Chi-square test and logistic regression models were used to screen the influencing factors for pregnancy complications.

The incidence of pregnancy complication was 13.94%. The following diseases had higher incidence than others: anemia (2.95%), premature rupture of membranes (2.51%), diabetes (1.92%), severe preeclampsia (1.43%), mild preeclampsia (1.27%), and hypertensive disorder complicating pregnancy (1.27%). Data from logistic regression models showed that pregnancy complications were related to maternal age, education level, number of caesarean sections, ways to terminate pregnancy, gestation weeks and number of fetuses.

The rate of pregnant complication is high, which should be treated in time to ensure the safety of pregnant women.
