Factors related to the age of attainment of nocturnal bladder control: an 8-year longitudinal study
Insights
Most children achieve nocturnal bladder control by age 8. However, 7.4% experience nocturnal enuresis due to failure to attain control or secondary onset, with biological factors playing a key role.
Area of Science:
- Pediatrics
- Developmental Psychology
- Urology
Background:
- Nocturnal enuresis, or bed-wetting, affects a significant percentage of children.
- Understanding the factors influencing the attainment of nocturnal bladder control is crucial for effective management.
Purpose of the Study:
- To investigate the age of achieving nocturnal bladder control in a New Zealand birth cohort.
- To identify predictors for the age of attaining nocturnal bladder control.
- To explore the relationship between psychosocial factors and nocturnal bladder control.
Main Methods:
- Longitudinal study of a birth cohort of New Zealand children.
- Data collection on nocturnal bladder control, enuresis, and associated factors.
- Statistical analysis to identify predictive factors.
Main Results:
- By 8 years of age, 96.7% of children had attained nocturnal bladder control, while 7.4% experienced nocturnal enuresis.
- Predictive factors for delayed control included family history of enuresis, developmental level at 1 and 3 years, and early sleep patterns.
- No significant association was found between psychosocial factors (socioeconomic background, life events, family changes) and the age of bladder control attainment.
Conclusions:
- The etiology of primary nocturnal enuresis appears to be predominantly biological.
- Psychosocial factors play a minimal role in the development of primary nocturnal enuresis.
- Early identification of biological risk factors may aid in managing nocturnal enuresis.
Abstract:
The age of attainment of nocturnal bladder control was studied in a birth cohort of New Zealand children. By 8 years of age, but all 3.3% of children had attained such control, but because some children had relapsed subsequent to the attainment of control, 7.4% of children had nocturnal enuresis. It was estimated that from 5 years of age onward between one half to two thirds of children experiencing nocturnal enuresis did so as a result of failure to attain nocturnal control and the remaining children had secondary or onset enuresis. Factors predictive of the age of attainment of nocturnal bladder control were a family history of enuresis, the child's developmental level at 1 and 3 years of age, and the child's early sleeping patterns. The age of attainment of bladder control was unrelated to a broad range of psychosocial factors including family social and economic background, family life-event measures, changes in parents in the family, and residential changes. These results favor the view that the etiology of primary enuresis is mainly biologic and that psychosocial factors play little role in this aspect of bed-wetting.
