PURPOSE
Children with Down syndrome (DS) have delayed psychomotor development, which determines
the level of difficulty in toilet training. The current study aims to estimate at what age they start and
complete toilet training compared to children with normal psychomotor development, as well as
to evaluate the toilet training method used and any association with lower urinary tract symptoms
(LUTS) and functional constipation.
MATERIAL AND METHODS
A case-control study was conducted between 2013 and 2015. All parents completed a question-
naire designed to assess the toilet training process. LUTS was assessed through the application of
the Dysfunctional Voiding Symptom Score. The presence of functional constipation was evaluated
according to the Rome III criteria.
RESULTS
The study included 93 children with DS and 204 children with normal psychomotor development
(Control Group- CG).The average age children started toilet training was 22.75 months in those with
DS and 17.49 months in the CG (p=0.001). In children with DS, the average age when completing
toilet training was 56.15 months and 27.06 months in the CG (p=0.001). Among children with DS,
females completed toilet training earlier (p=0.02). The toilet training method used most often was
child-oriented approach in both groups. There was no association with the presence of LUTS or
functional constipation and the age of beginning and completing toilet training in both groups.
CONCLUSIONS
Children with DS experienced prolonged toilet training time compared to normal ones. Females with
DS complete toilet training earlier. Age of finisshing toilet training was not associated with LUTS
or constipation. Other cohort studies are essential to gain insight into the toilet training process in
children with DS.
