The Effect of Body Mass Index on Pelvic Floor Support 1 Year Postpartum.
Elevated body mass index (BMI) is associated with the incidence, prevalence, and progression of pelvic organ prolapse (POP). This study investigated the effect of peripartum BMI on pelvic floor support 1 year postpartum (PP1y). One hundred eight nulliparous women had their BMI recorded and underwent POP assessments using the Pelvic Organ Prolapse Quantification System at baseline, third trimester (36th to 38th week of pregnancy [G36-38w]), and PP1y. Pelvic organ prolapse was defined as ≥stage II. Women gained on average 1.9 kg between baseline and PP1y. After adjustment, increasing BMI PP1y was associated with increasing anterior wall descent (P < .0001) and higher odds of having POP PP1y (odds ratio: 1.41, 95% confidence interval: 1.01-1.97, P = .045). Trial of labor compared to unlabored cesarean delivery, POP G36-38w, and decreased fetal weight were independently associated with anterior vaginal wall laxity PP1y. Our finding suggests that postpartum BMI influences pelvic floor laxity 1 year after delivery. Postpartum weight reduction may serve as a strategy for POP prevention in some women.
