RESUMO
OBJECTIVE@#To investigate pregnancy complications and related determinants, and provide scientific evidence for maternal health care.@*METHODS@#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.@*RESULTS@#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.@*CONCLUSION@#The rate of pregnant complication is high, which should be treated in time to ensure the safety of pregnant women.
