Non-biological determinants of paediatric bladder bowel dysfunction: A pilot study

Abstract

Objectives: Children with bladder and bowel dysfunction (BBD) constitute a significant proportion of referrals at paediatric urology clinics worldwide, presenting with a wide range of symptom severity that may significantly affect quality of life. Non-biological factors may play a key role in triggering BBD severity, but these underpinning causes of BBD during childhood are still unknown. The aim of this study was to identify the effects of personal, family related and environmental variables on the severity of BBD symptoms in school-aged children.

Study design: A pilot, prospective, observational study was conducted on 53 children diagnosed with BBD, and their legal guardian(s), on their first referred visit to a paediatric BBD clinic led by nurse practitioners. Upon receiving consent, patients and their legal guardian(s) completed three study questionnaires, with the guidance of research coordinators. The first questionnaire was the Dysfunctional Voiding Scoring System (DVSS); the second, a three-part questionnaire used to collect demographic information and data on the patient, their family and environmental characteristics; and the third gathered a detailed history of the child's lifestyle regimen, focusing on their bowel and bladder function.

Results: Most of the children were female (66%), with an average age of 8.35 years. Most children attended public schools (74%) and none reported failing a grade. The mean parental age was 41.4 years (SD = 4.9 years), 62% of the families had two children and 53% were Caucasian. The mean DVSS score for this sample was 9.9 (SD = 4.2, range 2-21). Daycare attendance, school problems and unplanned pregnancy showed statistically significant influences on the severity of BBD and were associated with higher DVSS scores according to the Table below.

Conclusions: Children with BBD attending urology outpatient clinics as new referrals had more severe symptoms when they were born from an unplanned pregnancy, attended daycare and/or had school problems. These findings suggest that interventions aimed at decreasing BBD severity, or preventing its onset in school-aged children, should focus on the environment surrounding them, specifically on the interaction between personal, familial and environmental factors. These factors seem to have an important effect on paediatric continence, as children grow and develop under numerous societal influences and social interactions.
