Objective: Knowledge on the relationship between sleep bruxism (SB) and sleep behaviors in children is still fragmental, especially when socioeconomic factors are concerned. To assess sleep behaviors in children with different frequencies of proxy-reported SB.

Methods: Parents of 1475 Colombian children, aged 9.8 ± 1.6 years, belonging to 3 different social layers, filled out a questionnaire on their childreńs sleep (Childreńs Sleep Habits Questionnaire [CSHQ]). Differences in sleep behaviors were assessed for the total sample and the three socioeconomic layers, using one-way ANOVA and Bonferroni post-hoc tests or Kruskal-Wallis and Dunn’s post-hoc tests, based on the normality of outcome variables.

Results: Most sleep patterns and daytime sleepiness were similar for children with different frequencies of proxy-reported SB, without differences among socioeconomic layers, whilst sleep disorders and parasomnias increased with the frequency of proxy-reported SB, independently on the socioeconomic layer (Bonferroni post-hoc<0.001). The association between sleep-related habits and the frequency of proxy-reported SB was different for each socioeconomic layer.

Conclusion: Among the various sleep behaviors under investigation, some sleep disorders and parasomnias seem to be associated with parental-reported SB in children. The influence of socioeconomic conditions on sleep behaviors seems not relevant. Based on these results, more specific studies on the association between different sleep behaviors are needed.
