BLADDER AND BOWEL DYSFUNCTION IN MOTHERS AND CHILDREN: A POPULATION-BASED CROSS-SECTIONAL STUDY.

Abstract

Recently it was shown an association between lower urinary tract symptoms in mothers and their children. However, the role of functional constipation in this binomial is unclear. To evaluate bladder and bowel dysfunction between mothers and children. A population-based cross-sectional study. Mothers and their children responded a self-administrated questionnaire composed by Rome IV criteria, International Consultation on Incontinence Questionnaire - Overactive Bladder, Dysfunctional Voiding Scoring System and demographic questions. A total of 441 mother-child pairs was obtained. Children's mean age was 9.1±2.7 years, with 249 (56.5%) female. Mothers' mean age was 35.7±6.1 years. Isolated constipation was present at 35 (7.9%) children and 74 (16.8%) mothers. Isolated lower urinary tract symptoms were present in 139 (31.5%) children and 92 (20.9%) mothers and bladder bowel dysfunction occurred in 51 (11.6%) children and 78 (17.7%) mothers. There wasn't any association between isolated lower urinary tract symptoms in children and isolated lower urinary tract symptoms in mothers (P=0.31). In univariate analysis there were an association between bladder bowel dysfunction in children and bladder bowel dysfunction in mothers (OR=4.8 IC 95% 2.6-9.6, P<0.001) and isolated constipation in children and isolated constipation in mothers (OR=3.0 IC 95% 1.4-6.4, P=0.003). In multivariate analysis mothers with bladder bowel dysfunction was the only independent factor associated with bladder bowel dysfunction in children (OR=5.4 IC 95% 2.5-11.6, P<0.001). Mothers with bladder bowel dysfunction are more likely to have a child with bladder bowel dysfunction. Association between these two dysfunctions plays an important role in this familiar presentation.
