Objective: To assess the impact and correlation of socioeconomic vulnerability on COVID-19 outcomes and social distancing in Brazil. Methods: The Gini Coefficient (GC), the Social Vulnerability Index (SVI), epidemiological data on COVID-19 epidemic in Brazil, and the Social Distancing Index (SDI) were retrieved from online databases and assessed for each Brazilian state. Data was statistically analyzed through non-parametric tests and multiple linear regressions. Results: The mean values for the GC and SVI were 0.495 and 0.261, respectively. A positive statistically significant correlation between the socioeconomic indicators and the three variables related to the COVID-19 outbreak was found. States with very low social vulnerability presented fewer deaths per 100 thousand inhabitants due to COVID-19 than states with moderate social vulnerability. SVI was a predictor of accumulated cases, confirmed deaths, and social distancing in Brazilian states during COVID-19. Conclusions: The COVID-19 outcomes and SDI in Brazilian states are correlated to the socioeconomic condition. The pandemic impacts are more severe in less favored communities.
Introdução: o presente estudo teve como objetivo avaliar o fluxo salivar, sintomas bucais e a qualidade de vida relacionada à saúde bucal em um grupo de pacientes com doenças neuromusculares. Materiais e Métodos: estudo transversal realizado com 30 indivíduos com doenças neuromusculares atendidos no ambulatório de neuroreabilitação de um hospital universitário brasileiro entre outubro e dezembro de 2017. Foram realizados anamnese e determinação do Fluxo Salivar em Repouso e do pH salivar. Para avaliação da qualidade de vida relacionada à saúde bucal foi empregado o questionário Oral Health Impact Profile-14. Aplicou-se análise descritiva dos dados e teste qui-quadrado, adotando-se o nível de significância de 5 % (p <0.05). Resultados: a Esclerose Lateral Amiotrófica foi a doença de base mais preva- lente (50 %). A média de Fluxo Salivar em Repouso foi de 0.44 ± 0.34 ml/min, sendo verificado hiperfluxo em 43.3 % dos pacientes e hipossalivação em 3.3 %. A média do pH salivar foi 6.47 ± 0.57. Os sintomas orais mais frequentes foram disfagia (56.7 %) e xerostomia (43.3 %). A média do Oral Health Impact Profile-14 foi de 5.54 ± 4.93 e 90 % dos pacientes apresentaram algum impacto das condições bucais na qualidade de vida. Os sintomas de disfagia, xerostomia, ardência bucal e sialorreia apresentaram associação estatisti- camente significante (p <0.05) com a qualidade de vida relacionada à saúde bucal. As dimensões do Oral Health Impact Profile-14 que apresentaram maiores percentuais foram a inabilidade psicológica (14.5 %) e a limitação funcional (13.5 %). Conclusão: a maioria dos pacientes apresentaram disfunção de glândulas salivares e a presença de sintomas bucais influenciaram negativamente a percepção de qualidade de vida dos indivíduos com doenças neuromusculares.
Online-available information has been considered an accessory tool to estimate epidemiology and collect data on diseases and population behavior patterns. This study aimed to explore the potential use of Google and YouTube relative search volume to predict social distancing index in Brazil during COVID-19 outbreak and verify the correlation between social distancing measures with the course of the epidemic. Data concerning the social distancing index, epidemiological data on COVID-19 in Brazil and the search engines trends for Coronavirus were retrieved from online databases. Multiple linear regression was performed and resulted in a statistically significant model evidencing that Google and YouTube relative search volumes are predictors of the social distancing index. The Spearman correlation test revealed a weak correlation between social distancing measures and the course of the COVID-19 epidemic. Health authorities can apply these data to define the proper timing and location for practicing appropriate risk communication strategies.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
