Main Findings
In our cohort, a shorter IPI of <24 months was associated with
a higher risk of anemia in late pregnancy. Shorter or longer IPIs are
associated with incomplete uterine rupture. These effects became
nonsignificant after controlling for possible confounders. The
relationship between incomplete uterine rupture and IPI after previous
CS was affected by the type of repeated CS. The incidence of GHP and GDM
was significantly increased among women with an IPI of ≥120 months, and
the correlation became nonsignificant after adjustment.
