Background: Sleep behavior and movement disturbance (SBMD) is of a relatively high prevalence in children and has a significant impact on their performance in daily activities and quality of life. Snoring, on the other hand, is considered one of the main causes of sleep disturbance in children. This study aims to assess the relationship between snoring and SBMD in 2 to 12 years old children in Qom city.

Materials and Methods: In this case-control study, 100 children with snoring and 100 healthy children were studied over 3 months. The parents took Berlin questionnaire on snoring and childhood sleep questionnaire. Data analysis was done using SPSS software version 18.

Results: There was a significant correlation in mean SBMD between case (13.78) and control (11.45) groups (p<0.001). Independent t-test indicated a significant difference between the case and control groups in the mean of SBMD (p<0.001). Also, significant relationships were seen between snoring and adenotonsilar hypertrophy (p<0.001) and apnea and SBMD (p=0.036), but there was not any relationships between SBMD and age, children less than 7 and more than 7 years old (p=0.231), and severity of snoring and SBMD (p=0.202).

Conclusion: This study demonstrates the importance of sleep disorders, especially snoring and SBMD and their relationship, in children. Sufficient attention to this issue can raise parents and physicians awareness and pave the way for early diagnosis and treatment of these disorders.
