Fetal birthweight and maternal urinary incontinence in Chinese primiparas: a population-based study.

ABSTRACT:

Background

Urinary incontinence (UI) is commonly linked to pregnancy and obstetric factors, but the association between fetal birthweight and maternal UI remains contentious. This study investigates the association between fetal birthweight and maternal UI and its subtypes in Chinese primiparas.

Methods

Cross-sectional data from 54,346 women aged 20 years and above were obtained from the 2019-2021 National Urinary Incontinence Survey. Restricted cubic spline (RCS) regression analysis and threshold effect analysis were used to explore the association between fetal birthweight and urinary incontinence and its subtypes.

Results
