Insights
Children with Down syndrome (DS) experience a high prevalence of functional constipation (FC). Delayed toilet training was associated with increased risk of FC in these children.
Area of Science:
- Pediatrics
- Gastroenterology
- Genetics
Background:
- Gastrointestinal and eating disorders are common in children with Down syndrome (DS).
- Functional constipation (FC) significantly impacts daily life for children with DS.
- Investigating bowel habits in DS is crucial for developing diagnostic and treatment guidelines.
Purpose of the Study:
- To determine the prevalence of functional constipation (FC) in children with Down syndrome (DS).
- To identify factors associated with FC in this population.
- To inform practice guidelines for pediatricians managing DS patients.
Main Methods:
- Observational, analytical, cross-sectional study of 36 children with DS.
- Parental interviews utilizing Rome IV criteria and Bristol Stool Scale for bowel habit assessment.
- Nutritional assessment using DS-specific growth curves.
Main Results:
- A high prevalence of FC was observed (41.7% of participants).
- Children with FC reported fewer bowel movements, harder stools, and experienced pain during defecation.
- Delayed toilet training (after 30 months) was associated with achieving bowel control.
Conclusions:
- Children with Down syndrome exhibit a high prevalence of functional constipation.
- Delayed sphincter training is linked to an increased risk of FC in children with DS.
- A standardized care protocol and flowchart can aid pediatricians in diagnosing and managing FC in this population.
Abstract:
Background/Objectives: Gastrointestinal and eating disorders are highly prevalent problems in children with Down syndrome (DS) and have a significant impact on their daily lives. It is important to investigate the bowel habits of children with DS, specifically the prevalence of functional constipation (FC), in order to develop practice guidelines for pediatricians that support diagnosis and treatment. Materials and Methods: This observational, analytical, and cross-sectional study was approved by the Ethics Committee and included 36 children with DS under pediatric outpatient follow-up at a university hospital. To assess bowel habits, an interview was held with the parents using the Rome IV criteria and the Bristol Stool Scale. The children were divided into two groups: those with and those without FC. Specific curves for individuals with DS were used for nutritional assessment. Results: The median age of the children was 46.6 months (5 to 144 months); a total of 80.5% of those included were eutrophic. The median age at initiation of toilet training was 36 months. Most children achieved bowel control when training started after 30 months of age. A total of 15 (41.7%) of the 36 children included were assigned to the group with FC, and 21 (58.3%) were assigned to the group without FC. The FC group had a lower frequency of bowel movements, hardened stools, pain during bowel movement, and used laxatives. According to the Rome IV criteria, the three most prevalent criteria were hard stools, large-volume stools, and painful bowel movements. Conclusions: Children with DS had a high prevalence of FC, and it was possible to identify an association between delayed sphincter training and FC. A care and monitoring protocol and flowchart are useful tools for the general pediatrician.
