Relative and Maximal Intra-abdominal Pressure and Postpartum Pelvic Floor Outcomes in Primiparas Delivered Vaginally.

ABSTRACT:

Objectives

This study aimed to explore associations between relative and maximal intra-abdominal pressure (IAP) on pelvic floor outcomes in primiparas delivered vaginally.

Methods

At 5-10 weeks and 1 year postpartum, we measured absolute IAP by vaginal sensor while participants lifted a weighted car seat (IAPLIFT) and performed isometric trunk flexion endurance (IAPTFE) and seated maximal strain (IAPSTRAIN). Primary outcomes, completed 1 year postpartum, included worse pelvic floor support (descent to or beyond the hymen) and positive symptom burden (bothersome symptoms in ≥2 of 6 domains on the Epidemiology of Prolapse and Incontinence Questionnaire). We calculated relative IAP (as absolute IAP/IAPSTRAIN).

Results

Of 542 participants, 9.7% demonstrated worse support
