Short inter pregnancy interval after CS does not affect incidence of placenta previa disorder
Interpregnancy interval (IPI) is defined as the time lapse between two consecutive pregnancies. It has also been defined as the time between the end of one pregnancy and the beginning of the next pregnancy. Normal IPI is defined as IPI between 18 and 36 months. Short IPI is defined as IPI less than 18 months.
An IPI less than 6 months is most often associated with adverse outcomes. Women who have short IPIs of less than 18 months have been linked with an increased risk of adverse perinatal outcomes, including placenta previa. However, there is paucity of data on the relationship between IPI and the risk of placenta previa and placenta accreta spectrum disorder in low-income settings where there are high aversions for cesarean section. The aim of the study by Uchenna Anthony Umeh and team was to determine and compare the incidence of placenta previa and the placenta accreta spectrum disorder following a previous cesarean section between women with short IPI and those with normal IPI.
A prospective cohort three-center study involving parturients who had previous cesarean section was conducted. Participants were included if pregnancy has lasted up to 34 weeks. Parturients with co-existing uterine fibroids, multiple gestations, premature rupture of membranes, and those with prior postcesarean delivery wound infection were excluded. The eligible women recruited were distributed into two groups, namely, short (<18 months) and normal (18–36 months) IPI. e outcome measures were incidences of placenta previa and placenta accreta spectrum disorder and factors associated with the occurrence of placenta previa. A univariate analysis was performed using the chi-square test or Mann–Whitney U test, wherever appropriate, to examine the signicance of the dierences in clinical variables.><18 months) and normal (18–36 months) IPI. The outcome measures were incidences of placenta previa and placenta accreta spectrum disorder and factors associated with the occurrence of placenta previa.
