Is there an association between verbal school bullying and possible sleep bruxism in adolescents?
The aim of this study was to determine the association between verbal school bullying and possible sleep bruxism (SB) in adolescents. A case-control study was carried out at the population level by recruiting 13- to 15-year-old participants among the attendants of schools of Itabira, Brazil. The case group was composed of 103 adolescents with possible SB (i.e. self- or parental-reported), while the control group included 206 adolescents without possible SB. All participants answered a questionnaire on the occurrence of their involvement in verbal school bullying episodes, based on the National School of Health Research (PeNSE) as well as an evaluation of their economic class according to the criteria of the Brazilian Association of Research Companies. Pearson's chi-square, McNemar test and conditional logistic regression were performed to assess the association between possible SB, verbal school bullying and economic class. There were 134 (43·3%) participants who reported involvement in verbal school bullying episodes as a victim, bully or both. The majority of them were males (90·3%). Adolescents with possible SB were more likely to have been involved in episodes of verbal school bullying (OR: 6·20; 95% CI: 3·67-10·48). Based on these findings, it can be suggested that possible SB in young teenagers is associated with a history of episodes of verbal school bullying.
