Epidemiological characteristics and related risk factors of pregnant women with placental abruption

Abstract

Objective To investigate the epidemiological characteristics and related risk factors of pregnant women with placental abruption (PA). Methods A total of 196 pregnant women with placental abruption in Luoyang First People’s Hospital from December 2014 to December 2018 were randomly selected as observation group, and 120 pregnant women with non-placental abruption were selected as control group. General information was collected from two groups of pregnant women, and epidemic characteristics and risk factors for placental abruption in pregnant women were analyzed. Results Among the 196 pregnant women with placental abruption, autumn and winter (28.6% in autumn and 29.59% in winter), residential cities (60.20%) and 20-29 years (52.55%) accounted for a relatively high proportion. The proportion of pregnant women with hypertension, premature rupture of membranes, polyhydramnios and mechanical injury in the observation group was higher than that in the control group, and the difference was significant (P<0.05). Pregnant women with high blood pressure during pregnancy, premature rupture of membranes, polyhydramnios, and mechanical damage are risk factors for PA(OR=1.879, 2.287, 1.954, 2.926, P=0.025, 0.016, 0.020, 0.012). Conclusions PA occurs frequently in urban pregnant women aged 20-29 years, which occurs more frequently in autumn and winter. The risk factors are hypertension during pregnancy, premature rupture of membranes, excessive amniotic fluid and mechanical damage.
