Objective: To explore the relationship between parenting styles and children's personality traits and parental-reported sleep bruxism (SB).
Methods: A total of 301 parents/caregivers of Brazilian children participated in this cross-sectional study and answered an online questionnaire addressing sociodemographic characteristics, sleep-related behaviors and parent-reported SB. The Brazilian versions of the Parenting Styles and Dimensions Questionnaire and the Eysenck Personality Questionnaire-Junior assessed children's parenting styles and personality traits. Descriptive analysis and multinomial logistic regression were used.
Results: Boys (OR=2.07; 95% CI=1.09-3.91) whose snoring (OR=2.98; 95% CI=1.55-5.73) were associated with mild parent-reported SB. Boys (OR=2.61; 95% CI=1.20-5.70) and high levels of neuroticism (OR=2.27; 95% CI=1.06-4.860) were associated with moderate/severe parent-reported SB. Authoritarian parenting attitudes decreased the likelihood of moderate/severe parent-reported SB (OR=0.37; 95% CI=0.16-0.86).
Conclusions: Parents/caregivers who exhibited more authoritarian attitudes reported a lower prevalence of moderate/severe children SB. Neuroticism trait and snoring influenced the severity of parent-reported SB.
