RESUMO Introdução: o tratamento ortodôntico visa à saúde bucal e ao reestabelecimento da função como objetivo final; no entanto, os efeitos psicológicos e sociais acabam sendo o principal motivo da procura pelo tratamento. Objetivo: determinar a associação entre a qualidade de vida relacionada à saúde bucal (QVRSB), a necessidade de tratamento ortodôntico e o bullying entre os adolescentes. Métodos: trata-se de um estudo epidemiológico transversal. Para avaliar a má oclusão, foi utilizado o Dental Aesthetic Index. O instrumento Oral Health Impact Profile-14 foi utilizado para analisar a QVRSB. O questionário Kidscape foi utilizado para verificar os casos de bullying. Também foram incluídas as variáveis: tratamento ortodôntico prévio e desejo de corrigir os dentes para melhorar a aparência. A análise multivariada foi realizada por meio de regressão logística, considerando-se a qualidade de vida ruim como variável resposta. Resultados: 815 adolescentes participaram da pesquisa. Houve associação, estatisticamente significativa, entre a qualidade de vida relacionada à saúde bucal e as variáveis: tratamento ortodôntico prévio (p= 0,0270), desejo de corrigir os dentes (p< 0,0001), sexo (p= 0,0309), bullying (p< 0,0001), frequência de episódios de bullying (p= 0,0170) e consequências do bullying (p< 0,0001). Foram considerados como fatores de risco para uma QVRSB ruim os adolescentes que não realizaram tratamento ortodôntico prévio a esse estudo (OR= 2,191) e aqueles que revelaram consequências negativas relacionadas aos episódios de bullying (OR= 3,042). Conclusão: a necessidade de tratamento ortodôntico não foi associada à qualidade de vida relacionada à saúde bucal, já o bullying e o tratamento ortodôntico prévio tiveram associação estatisticamente significativa com essa variável.

ABSTRACT Introduction: Orthodontic treatment aims at oral health and restoration of function as main objectives, however, psychological and social effects end up being the main reason for the demand for treatment. Objective: To determine the association between the oral health-related quality of life (OHRQoL), the need for orthodontic treatment and bullying among Brazilian teenagers. Methods: This was a cross-sectional epidemiological study. To assess the malocclusion, the Dental Aesthetic Index was used. And the Oral Health Impact Profile-14 was used to analyze the OHRQoL. The Kidscape questionnaire was used to investigate cases of bullying. The following variables were also included: previous orthodontic treatment and a desire to fix the teeth to improve one’s appearance. Multivariate analysis was performed using logistic regression considering the poor OHRQoL as a response variable. Results: 815 teenagers participated in the study. There was a statistically significant association between oral health-related quality of life and the variables: previous orthodontic treatment (p= 0.0270), desire to fix the teeth (p< 0.0001), sex (p= 0.0309), history of being a victim of bullying (p< 0.0001), frequency of bullying episodes (p= 0.0170), and consequences of bullying (p< 0.0001). The following were considered as risk factors for poor OHRQoL: lack of previous orthodontic treatment (OR = 2.191) and negative consequences of bullying (OR = 3.042). Conclusion: The need for orthodontic treatment was not associated with the OHRQoL; however, bullying and previous orthodontic treatment had a statistically significant association with this variable.

Abstract INTRODUCTION: In the 1990s, Brazil adopted a public policy that allowed for universal, free access to antiretroviral therapy (ART). Since then, treatment adherence has become a new challenge for administrators of sexually transmitted disease/acquired immunodeficiency syndrome (STD/AIDS) policies. This study quantified adherence to ART and verified whether there is an association between sociodemographic variables and clinical/laboratory data in human immunodeficiency virus (HIV)-infected patients. METHODS: This was a cross-sectional, exploratory study with a quantitative approach that was conducted over 8 months. The target population contained patients who were assisted at the ambulatory care facility specialized in STD/AIDS of a medium-size city located in Northwest São Paulo. In order to verify the level of adherence to ART, a validated CEAT-VIH (Assessment of Adherence to Antiretroviral Therapy Questionnaire) questionnaire was used. Sociodemographic aspects and clinical/laboratory data were obtained from the medical records. The results were analyzed using the Student's t-test and Pearson's coefficient. RESULTS Herein, 109 patients were interviewed, 56% of whom were male. The age of the population ranged 18-74 years (mean 45.67 years). Adherence to ART was classified as insufficient in 80.7% of cases. There was an association between ART adherence and presence of symptoms and/or opportunistic infection (p=0.008) and economic status (p<0.001). CONCLUSIONS: Adherence to ART among HIV carriers cared for by the public health system is low. Patients who reported a favorable economic status and those without symptoms and/or opportunistic infection demonstrated greater treatment adherence than those who needed to take more than 3 pills a day.

RESUMO Objetivo: Analisar o nível da autoestima de adolescentes brasileiros e verificar as possíveis associações de desfecho com a necessidade de tratamento ortodôntico e bullying. Métodos: Estudo epidemiológico transversal de base populacional. A população foi composta por adolescentes de 11 a 16 anos, matriculados na rede pública de ensino de um município de médio porte do noroeste paulista. Foi realizado um exame bucal utilizando o índice Dental Aesthetic Index (DAI), para verificar a necessidade de tratamento ortodôntico, e um questionário autoaplicável, contendo os índices Global Self-Evaluation (GES), para identificar o nível de autoestima, e o Kidscape, para detecção de bullying. A análise dos dados foi feita utilizando estatística descritiva, análises de associação e regressão logística multivariada. Resultados: No total, 815 adolescentes participaram da pesquisa. Houve associação estatisticamente significante entre autoestima e as variáveis: sexo (p<.0001), vontade de corrigir os dentes para melhorar a aparência (p=0.0006), vítima de bullying (p<.0001), frequência com que sofreu bullying (p=0.0111) e consequências do bullying (p<.0001). Apresentaram-se como fator de risco significante para uma autoestima muito negativa a cor da pele não branca (OR=1.914) e vítimas de bullying que tiveram consequências negativas após o episódio (OR= 3.343). Conclusão: Houve associação entre as variáveis autoestima e bullying. Aqueles que relataram consequências negativas sobre o bullying apresentaram chances três vezes maiores de ter autoestima muito negativa, já as chances dos adolescentes com cor da pele não branca foram quase duas vezes maiores. Não houve associação estatisticamente significante entre autoestima e necessidade de tratamento ortodôntico.

ABSTRACT Objective: The aim of this study was to analyze self-esteem among Brazilian adolescents and also verify possible associations between the variables: the need for orthodontic treatment and bullying. Methods: The cross-sectional, population-based epidemiological study consisted of a sample composed of adolescents from 11 to 16 years of age, enrolled in the public school system of a medium-sized municipality in the northwest of the State of São Paulo, Brazil. A dental examination was performed using the Dental Aesthetic Index (DAI) in order to verify the need for orthodontic treatment and a self-administered questionnaire containing the Global Self-Evaluation (GSE) indices to identify the level of self-esteem and Kidscape in order to detect bullying. Data analysis was performed using descriptive statistics, association analysis and multivariate logistic regression. Results: A total of 815 adolescents participated in the study. There was a statistically significant association between self-esteem and the variables: sex (p <.0001), willingness to straighten teeth to improve appearance (p = 0.0006), bullying victim (p <.0001), frequency of bullying = 0.0111) and consequences of bullying (p <.0001). A significant risk factor for non-white adolescents' very negative self-esteem (OR = 1.914) was present together with bullying victims who had had negative consequences after the episode (OR = 3.343). Conclusion: There was an association between the self-esteem and bullying variables. Those who reported negative consequences on bullying were three times more likely to present very negative self-esteem, and the chances of non-white adolescents to show negative self-esteem were almost twice as high. There was no statistically significant association between self-esteem and the need for orthodontic treatment.
