ABSTRACT
Abstract This study aimed to investigate the impact of school bullying and oral health-related verbal bullying on the occurrence of bruxism associated with poor sleep quality among adolescents. This cross-sectional study was nested in a cohort study performed with a sample of children from southern Brazil. Possible sleep bruxism was determined by the question: "Has anyone told you that you grind your teeth in your sleep?" Sleep quality was determined by answering the following question: "How would you classify the quality of your sleep?". The outcome was created by combining occurrence of sleep bruxism and poor sleep quality. The Sense of Coherence (SOC) was assessed using the SOC-13 scale. Bullying was investigated using the victim scale of the Olweus Bullying Questionnaire and oral health-related verbal bullying using an item from the Child Perceptions Questionnaire-11-14. Demographic, socioeconomic, psychosocial, and clinical data were also collected. Poisson regression models with robust variance were used. Results were expressed as prevalence ratio (PR) and 95% confidence intervals (95% CI). A total of 429 adolescents with a mean age of 12.6 (standard deviation 1.3) years were evaluated. The prevalence of bruxism associated with poor sleep quality was 23.7%. Victims of school bullying (PR 2.06; 95%CI: 1.01-4.22) and oral health-related verbal bullying (PR 1.87; 95%CI: 1.18-2.95) presented higher prevalence of bruxism associated with poor sleep quality. Factors such as skin color and SOC were also associated with the outcome. These findings suggest an association between episodes of bullying and bruxism related to poor sleep quality.
ABSTRACT
Avaliar a associação entre variáveis socioeconômicas e relacionadas a saúde bucal no suporte social percebido por gestantes. Esse estudo transversal incluiu uma amostra obtida em conglomerados de gestantes atendidas no serviço público de saúde no sul do Brasil. As gestantes responderam questionários acerca de características demográficas, socioeconômicas e relacionadas à saúde bucal. O suporte social foi avaliado através da escala Medical Outcomes Study. As variáveis clínicas incluíram cárie dentária não tratada e sangramento gengival. Análise de Regressão de Poisson em multinível foram utilizados para avaliar a influência dos preditores no suporte social. A amostra foi composta por254 gestantes. Gestantes com pior autopercepção de saúde bucal, níveis extensivos de sangramento gengival e com menor nível socioeconômico apresentaram um pior suporte social. Fatores socioeconômicos e relacionados à saúde bucal exerceram impacto no suporte social percebido por gestantes.
To evaluate the association between socioeconomic and oral health-related variables in the social support perceived by pregnant women. This cross-sectional study included a sample obtained from clusters of pregnant women who attended public health services in southern Brazil. The pregnant women answered questionnaires about demographic, socioeconomic, and oral health characteristics. Social support was assessed using the Medical Outcomes Study scale. Clinical variables included untreated dental caries and gingival bleeding. Multilevel Poisson regression analysis was used to assess the influence of predictors on social support. The sample consisted of 254 pregnant women. Those with poorer self-perceived oral health, extensive levels of gingival bleeding, and lower socioeconomic status, presented poor social support. Socioeconomic factors and factors related to oral health had an impact on the social support perceived by pregnant women.
