RESUMO
Introdução: O presente estudo avaliou a correlação entre cobertura vacinal e mortalidade por covid-19 em Santa Catarina, a fim de evidenciar o comportamento da imunização coletiva para o controle da pandemia da covid-19. Métodos: Foi realizado um estudo ecológico que incluiu os casos confirmados e óbitos por covid-19 em Santa Catarina entre 12/03/2020 e 03/01/2022, além da cobertura vacinal de covid-19 de 18/01/2021 a 31/12/2021. A análise de dados foi realizada em dois períodos para posterior avaliação comparativa, sendo obtidas taxas mensais. Resultados: O maior número de casos de covid-19 relacionou-se ao sexo feminino (52,2%) e à população de 20 a 49 anos (62,1%). O maior número de óbitos foi atrelado ao sexo masculino (57,8%) e à população acima de 60 anos (68,5%). As macrorregiões Foz do Rio Itajaí e Sul apresentaram as maiores taxas de incidência e mortalidade. Ao comparar os dois períodos, houve redução da taxa de incidência (58,3%) e mortalidade (55,6%), concomitante ao aumento de 50% no número de vacinados com o esquema completo. Conclusão: Observou-se uma correlação negativa (r = - 0,05) entre cobertura vacinal e taxa de mortalidade, evidenciando que a mortalidade pela covid-19 diminuiu à medida que a vacinação foi aumentando (p = 0,08).
Introduction: The present study evaluated the correlation between vaccination coverage and mortality from covid-19 in Santa Catarina, in order to demonstrate the behavior of collective immunization for the control of the covid-19 pandemic. Methods: An ecological study was carried out that included confirmed cases and deaths by covid-19 in Santa Catarina between 03/12/2020 and 01/03/2022, in addition to the covid-19 vaccine coverage from 01/18/2021 to 31 /12/2021. Data analysis was performed in two periods for later comparative evaluation, with monthly rates being obtained. Results: The highest number of cases of covid-19 was related to the female sex (52.2%) and the population aged 20 to 49 years (62.1%). The largest number of deaths was linked to males (57.8%) and the population over 60 years (68.5%). The macro-regions Foz do Rio Itajaí and Sul had the highest incidence and mortality rates. When comparing the two periods, there was a reduction in the incidence rate (58.3%) and mortality (55.6%), concomitant with a 50% increase in the number of vaccinated with the complete regimen. Conclusion: There was a negative correlation (r = - 0.05) between vaccination coverage and mortality rate, showing that mortality from covid-19 decreased as vaccination increased (p = 0.08).
RESUMO
INTRODUCTION: Occupational accidents occur as a result of work, and can lead to bodily harm or functional impairments that lead to death, or to the reduction or loss of working capacity. Occupational accidents are associated with two possible outcomes: morbidity or mortality. Morbidity refers to the subset of a population that develops an illness over a given period of time, while mortality refers to the number of individuals who die over a specified time period. OBJECTIVES: To assess occupational morbidity and mortality in Brazil in the period of 2009 to 2016. METHODS: An ecological study was conducted based on secondary data collected from incident records in the Social Security database. RESULTS: The outcomes of all occupational accidents reported in Brazil from 2009 to 2016 were extracted from the database. These data were then classified by geographical region and category in the National Classification of Economic Activities (Classificação Nacional de Atividades Econômicas), so as to calculate the prevalence of each outcome and the accident mortality rates, and compare these values across regions and occupational categories. CONCLUSIONS: The data show that the outcomes of occupational accidents are directly associated with socioeconomic sectors and the sociocultural characteristics of different regions in the country. These results make an important contribution to the characterization of occupational morbidity and mortality in Brazil.
