dc.description.abstractStudy Objectives: Sleep bruxism (SB) is common in children and is associated with somatic symptoms and sleep disturbance. Etiological theories posit the role of anxiety, suggesting youth with anxiety disorders may be at high-risk for SB, but empirical data are lacking. Furthermore, parent report rather than polysomnography (PSG) has been used to examine SB-anxiety relationships in children. We examined rates of PSG detected compared to parent-reported SB in children with generalized anxiety disorder (GAD) and healthy controls. Associations among SB, somatic complaints, and sleep disturbance were also examined. Methods: Thirty-one children, aged 7-11 years, completed one night of PSG monitoring and 7 daily reports of somatic symptoms. Bruxism events were scored during rapid eye movement (REM) sleep and non-REM sleep stages 1 and 2. Results: Almost one-third of children showed evidence of SB based on PSG. No associations were identified between parent-reported and PSG-detected SB. Rates of SB did not differ between anxious and control groups, though children with GAD showed more tonic bruxisms during REM sleep. Presence of SB predicted more muscle aches and stomach aches, and children with SB had more awake time after sleep onset than non-bruxers. Conclusions: Results indicate poor concordance between PSG-detected and parent reported SB in children, suggesting that parent report alone is not a reliable method for detection. The lack of association between SB and anxiety status suggests that stress sensitivity rather than anxiety per se, may be predictive of SB. Associations between SB, somatic symptoms, and sleep disturbance are congruent with the broader literature.en
