A pendularidade é uma importante medida para avaliar os processos de integração das cidades e a dinâmica populacional regional. Em 2015, o IBGE identificou a intensificação dos movimentos pendulares entre os municípios do leste fluminense, de Arraial do Cabo a São João da Barra, considerando-os aspectos relevantes da urbanização brasileira. Contudo, pouco se sabe sobre o peso da pendularidade entre esses municípios e o nível de interação que eles estabelecem com Macaé, principal destino dos pendulares na região. Esse trabalho analisa o grau de integração regional do vetor leste fluminense, a partir dos dados censitários de 2000 e 2010. A pendularidade por trabalho e/ou estudo observada em Macaé o coloca em posição de destaque entre os municípios selecionados. Afirmamos, portanto, que Macaé não é apenas uma cidade em movimento, mas também um município potencialmente integrador do mercado de trabalho das demais municipalidades da região. É em torno desse município que o tecido urbano regional tem se reorganizado. Esse estudo pode iluminar novas discussões sobre os processos recentes de urbanização no estado do Rio de Janeiro, sobretudo por se tratar de uma região demograficamente integrada, mas politicamente fragmentada.
Vaccination campaigns played a crucial role in reducing the incidence of COVID-19. However, a scant number of studies evaluated the impact of vaccination on case fatality rates (CFRs), including in Brazil. Our study aimed to compare CFRs according to vaccination status among subjects living in Arapongas (Paraná State, Brazil), considering the age composition of the population. Several strategies adopted by the Arapongas City Hall to minimize the spread of the virus were also elaborated upon. We accessed the 2021 database of the Arapongas Municipal Health Department, in which a total of 16,437 confirmed cases and 425 deaths were reported. The CFR was calculated as the ratio between COVID-19 deaths and the number of confirmed cases. Differences in age composition between unvaccinated and fully vaccinated individuals were observed in our study. Considering that CFR is a crude indicator and is highly sensitive to the age composition of the population, we adopted the average age distribution of confirmed cases among the three vaccination statuses (unvaccinated, partially, and fully) as a standard age distribution. The age-standardized CFR for unvaccinated and fully vaccinated groups were 4.55% and 2.42%, respectively. Fully vaccinated individuals showed lower age-specific CFRs in all age groups above 60 years than unvaccinated populations. Our findings strengthen the role of vaccination as a critical measure for preventing deaths among infected people and is particularly important to the ongoing reassessment of public health interventions and policies.
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.
