Insights
Incontinence in children is not linked to weight. This study found no association between a child's weight category and the type or frequency of urinary incontinence (UI).
Area of Science:
- Pediatric Urology
- Clinical Pediatrics
- Obesity Research
Background:
- Urinary incontinence (UI) is a common condition in children presenting to specialist clinics.
- The role of weight and obesity in pediatric UI requires further investigation.
- Understanding associations can inform clinical management and public health strategies.
Purpose of the Study:
- To investigate the relationship between body weight and the characteristics of urinary incontinence in children.
- To determine if weight status influences the type or frequency of daytime urinary incontinence (DUI) and nocturnal enuresis (NE).
Main Methods:
- Retrospective review of 862 children's medical records from a tertiary hospital incontinence clinic (2004-2014).
- Data collected included weight, height, age, gender, UI type/frequency, and bowel habits.
- Statistical analyses (chi-squared tests, logistic regression) examined associations between weight categories and UI outcomes.
Main Results:
- 28% of the study cohort were overweight or obese.
- No significant differences in the prevalence or frequency of nocturnal enuresis (NE) or daytime urinary incontinence (DUI) were observed between underweight/normal weight and overweight/obese children.
- Specific findings: NE (34% vs. 39%), DUI (7% vs. 9%), combined NE/DUI (58% vs. 52.1%), NE frequency (83% vs. 82%), DUI frequency (52% vs. 58%).
Conclusions:
- In a large cohort of children attending a specialist incontinence clinic, body weight was not found to be associated with the type or frequency of urinary incontinence.
- These findings suggest that weight status is not a primary determinant of UI presentation in this clinical population.
Aim:
To explore associations between weight and type/frequency of urinary incontinence (UI) in children presenting to a tertiary hospital incontinence clinic.
Methods:
We retrospectively reviewed medical records of children who first attended the incontinence clinic at The Children's Hospital at Westmead between January 2004 and December 2014. A random sample of 1000 children was selected from 2022 patient records, and data were collected on weight, height, age, gender, UI parameters, bowel habits and medical history. Associations between predictors (weight categories, gender, snoring, constipation, faecal incontinence) and outcomes (daytime urinary incontinence (DUI) and nocturnal enuresis (NE)) were examined using χ2 tests and logistic regression analysis.
Results:
A total of 862 children were included in the study; 54% were male, and 28% were overweight/obese. No evidence of difference was found between the underweight/normal and overweight/obese weight children with NE (34 vs. 39%), DUI (7 vs. 9%) or combined NE and DUI (58 vs. 52.1%), P = 0.23. The frequency of NE (83 vs. 82%, P = 0.56) and DUI (52 vs. 58%, P = 0.20) was similar between the weight groups.
Conclusion:
In a large cohort of children presenting to a tertiary incontinence clinic, weight was not associated with the type or frequency of UI.
