Prevalence of dysphagia symptoms in Cretan children and adolescents with neurological disorders

Objectives: Dysphagia is defined as any feeding or swallowing dysfunction at one or more stages of digestion. This study aims to investigate the prevalence of dysphagia symptoms in children and adolescents with neurological disorders and its relationship with the specific characteristics of the subjects.

Methods: Using data from general hospital/paediatric department visits in Heraklion, Crete, Greece, a cross-sectional study design was implemented over a seven-month period (2017-18), and a total of 268 children and adolescents were recruited. Demographic data and medical profiles were recorded, focusing on the most obvious and frequent clinical features of feeding and swallowing disorders per stage (oral-OS, pharyngeal-PS, and oesophageal-ES).

Results: In the sample, 54.9% were boys and the mean age was 5.9 years; the most prevalent International Statistical Classification of Diseases and Related Health Problems (ICD-10) disorder was mental and behavioural disorders (37.3%). The prevalence of dysphagia symptoms was 24.3% during the OS (95% CI: 19.0-29.9), 18.3% in the PS (95% CI: 14.0-23.2), and 20.1% in the ES (95% CI: 15.7-25.4). At least one symptom of dysphagia was observed during the OS, PS, and ES in 42.5% (95% CI: 36.7-48.5) of the sample. The presence of dysphagia seems to be related to lower age (Odds Ratio [OR] = 0.45, p < 0.001), higher ICD-10 comorbidity (OR = 1.89, p < 0.05), or medication use (OR = 2.31, p < 0.05).

Conclusions: A high prevalence of dysphagia was found in children and adolescents with neurological disorders, while lower age, comorbidity, and medication use emerged as factors that required better management.
