ObjectivesThe aims of this study were to investigate the prevalence of sleep bruxism in children in Japan, and its relationships with sleep-related factors and daytime problematic behavior.
Subjects and MethodsGuardians of 6023 children aged 2-12years completed the Japanese Sleep Questionnaire. Multiple regression analysis and structural equationmodeling were performed.
ResultsSleep bruxism was reported in 21.0% children (n=1263): the prevalence was highest in the age group of 5-7years (27.4%). Multiple regression analysis showed that sleep bruxism had significant correlations with age 5-7years (OR: 1.72; P<0.0001), Moves a lot during sleep' (OR: 1.47; P<0.0001), sleeps with mouth open' (OR: 1.56; P<0.0001), and snores loudly' (OR: 1.80; P<0.0001). In structural equationmodeling, sleep bruxism had a significant but weak direct effect on daytime problematic behavior, while sleep bruxism significantly correlated with obstructive sleep apnea, which had a higher direct effect on daytime problematic behavior.
ConclusionsSleep bruxism was reported in 21.0% of Japanese children and had independent relationships with age, movements during sleep, and snoring. A comorbidity of sleep-disordered breathing might be related to daytime problematic behavior in children with sleep bruxism.
