Factors Predicting Atypical Development of Nighttime Bladder Control

Area of Science:

• Pediatrics
• Developmental Psychology
• Epidemiology

Background:

• Childhood bedwetting (nocturnal enuresis) affects a significant number of children.
• Understanding the longitudinal patterns and risk factors for bedwetting is crucial for effective intervention.

Purpose of the Study:

• To identify distinct longitudinal patterns (phenotypes) of bedwetting frequency from ages 4 to 9 years.
• To investigate associations between these bedwetting patterns and factors like developmental delay, parental history, birth weight, and gestational length.

Main Methods:

• Utilized data from 8,769 children in the UK Avon Longitudinal Study of Parents and Children cohort.
• Employed longitudinal latent class analysis to define bedwetting trajectories.
• Examined associations with sex, developmental level, parental history, birth weight, and gestational length.

Main Results:

• Identified five latent classes: normative, infrequent delayed, frequent delayed, infrequent persistent, and frequent persistent bedwetting.
• Male gender, developmental delay (e.g., social skills), and maternal history of bedwetting were significantly associated with increased odds of persistent bedwetting.
• Low birth weight and shorter gestation showed minimal association with bedwetting frequency.

Conclusions:

• Described developmental trajectories of nighttime bladder control in children.
• Identified key predictors for the persistence of bedwetting into school age.
• Highlighted the need for enhanced understanding of risk factors to identify and support children struggling with continence.
