Prevalence of anterior open bite and associated factors in schoolchildren in a municipality of southern Brazil / Prevalência de mordida aberta anterior e fatores associados em escolares de um município do sul do Brasil

Introduction: Open bite can generate relevant psychosocial impact in the daily life of the patient, both from the aesthetic and functional point of view. Objective The aim of this study was to estimate the prevalence and factors associated with the anterior open bite in children in the first school year in a municipality in southern Brazil. Material and method A cross-sectional study was carried out with six-year-old schoolchildren in Palhoça/SC. Interviews were conducted with mothers to gather socioeconomic and non-nutritive sucking habits information. Children oral clinical examinations were carried out in schools. Multivariate analyses were performed using Poisson regression with a robust estimator. The study involved 655 children, 50.5% being female. Result The prevalence of anterior open bite was 14.1% (95% CI 11.5; 16.7). Girls exhibited a lower prevalence [PR= 0.96 (95% CI 0.94; 0.99) p= 0.024] and those children who used a pacifier exhibited a higher prevalence of anterior open bite [PR= 1.04 (95% CI 1.01; 1.07) p= 0.003]. Conclusion The prevalence was 14.1% and that it was associated with gender and the use of pacifier, in a statistically significant and independent way.

Objetivo Estimar a prevalência e os fatores associados à mordida aberta anterior em crianças do primeiro ano escolar de um município do sul do Brasil. Material e método Estudo transversal constituído por escolares de seis anos de idade de Palhoça/SC.

Análises multivariadas foram realizadas por meio de regressão de Poisson com estimador robusto. Resultado O estudo envolveu 655 crianças sendo 50,5% do sexo feminino. A prevalência de mordida aberta anterior foi de 14,1% (IC 95% 11,5; 16,7). Meninas apresentaram prevalência menor [RP= 0,96 (IC 95% 0,94; 0,99) p= 0,024] e aqueles que utilizaram chupeta apresentaram uma maior prevalência [RP= 1,04 (IC 95% 1,01; 1,07) p= 0,003]. Conclusão A prevalência foi de 14,1% associada de forma estatisticamente significativa e independente com sexo e utilização de chupeta.

Epidemiological Impact and Hospitalization costs applied to dengue in the Midwest region of Minas Gerais state, Brazil, from SUS perspective.

BACKGROUND & OBJECTIVES: Dengue is considered one of the greatest public health challenges in the world, especially, for tropical and subtropical countries. Brazil highlights with considerable number of registers associated with this arbovirus, with emphasis on the state of Minas Gerais and its municipalities in regions such as the midwest. We aimed to evaluate the economic and epidemiological impact of dengue in the midwest region of minas Gerais, from SUS perspective. METHODS: Our study evaluated the epidemiological impact of dengue fever in the midwest region of Minas Gerais using data applied to Divinópolis city from SUS perspective between 2000 to 2015 considering SIH/SUS database (hospitalization registers) and 2007 to 2017 using the SINAN database (notification cases). We analyzed the number of notification registers and hospital services, as well as their costs, from a SUS perspective associated with this infection. RESULTS: There were 26,516 notifications associated with dengue, with 21,953 cases being confirmed by SEMUSA, with a median incidence of 211 cases/100,000 inhabitants of dengue notifications between 2007 and 2017. The southeast and southwest regions in the municipality are highlighted with high number of cases. Additionally, 160 hospitalizations were recorded with 33.79% in individuals between 15 and 34 years old and expenses of USD 53,737.21 for SUS between 2000 and 2015. INTERPRETATION & CONCLUSION: Divinópolis is the reference (social and economic) municipality of the midwest region in Minas Gerais state. Our study is the first conducted involving a long period of follow up applied to dengue context in this locality, especially, including the costs associated with hospitalization services. We hope to contribute to the discussions regarding the coping strategies of the disease, considering the impact in its different regions, highlighting the need for continued efforts and initiatives aimed at combating the vector of this and other arboviruses such as Zika and chikungunya.
