Relationship between enuresis and obstructive sleep apnea–hypopnea syndrome in children

Abstract

Objective We explored the relationship between enuresis and obstructive sleep apnea–hypopnea syndrome (OSAHS) in children and influencing factors of enuresis with OSAHS. Methods We recruited 196 children ≥5 years old from the otolaryngology outpatient department, who experienced snoring and underwent nasopharynx lateral radiography and in-laboratory polysomnography. We analyzed correlations between the apnea–hypopnea index (AHI) and lowest oxygen saturation (L-SaO2) with age, body mass index (BMI), tonsil size, and adenoidal–nasopharyngeal (A/N) ratio using the Pearson correlation test. Differences in severe OSAHS prevalence, age, AHI, L-SaO2, tonsil size, and A/N ratio between children with and without enuresis were assessed using the chi-square test and t-test. Risk factors of enuresis were analyzed using logistic regression. Follow-up was conducted to assess remission in children with enuresis after adenotonsillectomy. Results BMI, tonsil size, and A/N ratio were correlated with AHI and L-SaO2. Severe OSAHS prevalence, AHI, tonsil size, and A/N ratio were higher and L-SaO2 were lower in children with enuresis. Logistic regression showed that BMI, AHI, tonsil size, and sleep apnea were risk factors for enuresis. Conclusions Our study findings showed that enuresis was associated with OSAHS in children. Adenotonsillectomy may improve the symptoms of enuresis.
