Development of bowel and bladder control in the mentally retarded

Area of Science:

• Developmental Pediatrics
• Neurodevelopmental Disorders
• Rehabilitation Medicine

Background:

• Bowel and bladder control are essential for independent living in individuals with intellectual disabilities.
• Previous research indicates challenges in achieving continence for this population.
• Understanding long-term continence outcomes is vital for support and intervention planning.

Purpose of the Study:

• To investigate the long-term development of bowel and bladder control in children with intellectual disabilities.
• To identify the prevalence of encopresis and incontinence at different developmental stages.
• To assess the impact of intellectual disability on continence acquisition.

Main Methods:

• A longitudinal cohort study of children with intellectual disabilities (IQ < 70) born in Northern Finland in 1966.
• Data collection on bowel and bladder control up to age 20 years for 105 participants.
• Retrospective analysis of continence milestones and persistent issues.

Main Results:

• 80% achieved bowel control by a mean age of 4.2 years.
• However, 30.5% remained encopretic at age 7, and 19% at age 20.
• Full bladder control was achieved by 62.9% at age 7 and 82.9% by age 20.

Conclusions:

• Continence development is significantly delayed and often incomplete in individuals with intellectual disabilities.
• Persistent encopresis and incontinence are common issues into adulthood.
• Systematic and appropriate toilet training interventions hold potential to significantly improve continence outcomes.
