Association between self-reported bruxism and academic performance in university students / Asociación entre bruxismo autorreportado y rendimiento académico de los estudiantes universitarios

Objective: To evaluate the association between self-reported bruxism and academic performance in students at a university in Lima, Peru. Material and Methods: A total of 203 students were evaluated in this study, between the ages of 19 and 35 years. Self-reported bruxism was measured using the Bruxism Assessment Questionnaire. Academic performance was evaluated using the Approval Index Scale. In addition, other variables were included such as employment status, socioeconomic level, stress, anxiety, among others. The association of variables were factored in using the chi-square test and the logistic regression presented the unadjusted and adjusted analisis. Results: The frequency of self-reported awake bruxism and sleep bruxism was 53.20% and 36.45%, respectively. Evidence revealed there was a statistically significant association between awake bruxism with stress and anxiety, and sleep bruxism with anxiety. Students with high academic performance (OR=2.36; IC del 95%:1.06-5.23) and low academic performance (OR=5.72; IC del 95%:1.28-25.57) were found to be more likely to have awake bruxism than those with medium academic performance. Conclusion: This study revealed a statistically significant association between self-reported awake bruxism and academic performance. However, in the future it is suggested to carry out a study with focus only on students with bruxism and with a larger sample of participants with low academic performance to confirm the association found between these variables.

Objetivo: Evaluar la asociación entre bruxismo autorreportado y rendimiento académico en estudiantes de una universidad privada de Lima, Perú. Material y Métodos: Un total de 203 estudiantes con edades comprendidas entre 18 a 35 años fueron encuestados en esta investigación. Para la evaluación del bruxismo autoreportado se aplicó el cuestionario 'Bruxism Assessment Questionnaire' en su versión en español. Asimismo, el rendimiento académico se evaluó mediante la escala de Índice de Aprobación (IA). Además, se incluyeron otras variables como situación laboral, estrés, ansiedad, entre otros. La asociación de variables se realizó mediante la prueba chi cuadrado y para el análisis crudo y ajustado se utilizó la regresión logística. Resultados: Se encontró una prevalencia de bruxismo de vigilia de 53.20% y de bruxismo de sueño de 36.45%. Se evidenció asociación estadísticamente significativa entre bruxismo de vigilia con estrés y ansiedad, y bruxismo de sueño con ansiedad. Se halló que los estudiantes con rendimiento académico alto (OR=2.36; IC del 95%:1.06-5.23) y rendimiento académico bajo (OR=5.72; IC del 95%:1.28-25.57) tienen más probabilidades de presentar bruxismo de vigilia que aquellos con rendimiento académico medio. Conclusiones: En el presente estudio se halló asociación estadísticamente significativa entre bruxismo de vigilia autorreportado y rendimiento académico. No obstante, a futuro se sugiere realizar un estudio a los estudiantes con presencia de bruxismo y con un mayor tamaño muestral de participantes con rendimiento académico bajo para afirmar la asociación encontrada entre dichas variables.

Análise da concordância entre as informações reportadas pelas mães e dos cartões de vacina das crianças no Brasil (2013 e 2015) / Analysis of the agreement between information on child vaccination reported by mothers and that on the children's vaccination cards in Brazil (2013-2015)

Resumo Introdução Este trabalho discute a possibilidade de utilização de informações sobre a vacinação infantil reportada pelas mães em inquéritos domiciliares para a construção de indicadores de cobertura vacinal no Brasil. Objetivo Avaliar o potencial das informações declaradas pelas mães sobre a imunização das crianças em inquéritos domiciliares como uma fonte para o cálculo do indicador de cobertura vacinal. Método Analisaram-se os indicadores de confiabilidade (precisão) e validade (concordância) entre as informações disponíveis nos cartões de vacina das crianças menores de 2 anos e as informações reportadas pelas mães em pesquisas domiciliares realizadas nos anos de 2013 e 2015 no município de Santo Antônio do Monte, Minas Gerais. Resultados O principal resultado mostra que, em um contexto de alta cobertura, as mães tendiam a informar sobre a vacinação de seus filhos de forma aleatória, ou seja, informações reportadas pelas mães apresentavam baixa validade. Conclusão Embora a coleta de informações dos cartões de vacina das crianças seja um procedimento mais custoso, essa é a forma mais adequada e confiável de se mensurar a cobertura vacinal no contexto brasileiro.

Abstract Background This study discusses the possibility of using information on child vaccination reported by mothers through household surveys to construct indicators of immunization coverage in Brazil. Objective Evaluate the potential of information reported by mothers on the immunization of children in household surveys as a source to calculate a vaccination coverage indicator. Method The indicators of reliability (accuracy) and validity (concordance) between the information available on the vaccination cards of children under two years of age and that reported by mothers in two household surveys conducted in 2013 and 2015 in the municipality of Santo Antônio do Monte, state of Minas Gerais, Brazil. Results The main result shows that, in a context of high coverage, the mothers tended to inform randomly about the vaccination of their children, that is, the information reported by mothers presented low validity. Conclusion Although collecting information from children's vaccination cards is a more costly procedure, it is the most adequate and reliable way to measure vaccination coverage in the Brazilian context.

Condicionantes de la satisfacción con la vida de los pueblos originarios en México / Conditioners of satisfaction with the life of native peoples in Mexico

Resumen: El objetivo fue estudiar las dimensiones de dominio de satisfacción, eudemonía, equilibrio de los afectos, plenitud del bienestar subjetivo y las de recursos materiales, relaciones sociales y salud como bienestar objetivo captadas por el módulo de bienestar autorreportado (BIARE 2014) para México, y aportar información sobre el perfil de satisfechos e insatisfechos en 2,759 hablantes de una lengua originaria de México. Se llevó a cabo un análisis discriminante para grupos de satisfechos e insatisfechos, con el objeto de reconocer las variables relacionadas con cada condición y una regresión logística que indicara las variables de riesgo y protectoras. Los resultados muestran que las interacciones sociales, redes, tipo y magnitud del apoyo social además de salud y convivencia son importantes para la diferenciación, mientras que la percepción retrospectiva de satisfacción y de logro son variables protectoras; el sentimiento de abatimiento es de riesgo para el grupo de satisfechos. Se discute en términos de la teoría de Cummins y Diener el concepto de bienestar local, personal, subjetivo y objetivo.

Abstract: The aim was to study the dimensions of the satisfaction domain, happiness, affective balance, fullness of subjective well-being and the material resources, social relations and health as an objetive welfare captured by the self-reported module of well-being (BIARE 2014) for Mexico and provide information on the profile of satisfied and dissatisfied in 2,759 speakers of a native languaje of Mexico. It conducted a discriminant analysis for groups of satisfaction, dissatisfaction, in order to recognize the variables related to each condition and logistic regression to indicate the risk and protective variables. The results show that social interactions, networks, type and extent of social support in addition to health and coexistence are important for differentiation while the hindsight of satisfaction and achievement are protective variables and the feeling of dejection is risk for the satisfied group. It is discussed in terms of the theory of Cummins and Diener the concept of local, personal, subjective and objetive well-being.
