Preprints are preliminary research reports that have not been certified by peer review. They should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
Preprints posted online allow authors to receive rapid feedback and the entire scientific community can appraise the work for themselves and respond appropriately. Those comments are posted alongside the preprints for anyone to read them and serve as a post publication assessment.

ABSTRACT
Objective:
To assess mortality during the COVID-19 pandemic according to social vulnerability by areas of Belo Horizonte (BH), aiming at strategies for vaccination.Methods:
Ecological study with mortality analysis, according to census tracts classified by the Health Vulnerability Index, a composite indicator that includes socioeconomic and sanitation variables. Deaths due to natural causes and COVID-19 were obtained from the "Mortality Information System", between the 10th and 43rd epidemiological weeks (EW) of 2020. Excess mortality was calculated by a time series model, considering observed deaths by EW, between 2015 and 2019, for census tracts. Mortality rates (MR) were calculated and age-standardized =using population estimates from 2010 census.Results:
Excess mortality in BH was 16.1% (n =1524) 11.0%, 18.8% and 17.3% in the low, intermediate and high vulnerability areas, respectively. The differences between observed and expected age-standardized MR by natural causes were equal to 59/100,000 inhabitants in BH, increasing from 31 to 77 and 95/100,000 inhabitants, in the areas of low, intermediate and high vulnerability, respectively. There was an aging gradient in COVID-19 MR, ranging from 4 to 611/100,000 inhabitants among individuals of 20-39 years and 75+ years. The COVID-19 MR per 100,000 elderly (60+ years) was 292 in BH, increasing from 179 to 354 and 476, in the low, intermediate and high vulnerability areas, respectively.Conclusion:
Inequalities in mortality, particularly among the elderly, combined with the limited supply of doses, demonstrate the importance of prioritizing socially vulnerable areas during vaccination against COVID-19.RESUMO
Objetivo:
Avaliar a mortalidade por áreas de Belo Horizonte (BH) durante a pandemia de COVID-19 conforme vulnerabilidade social, visando estratégia de vacinação.Métodos:
Estudo ecológico com análise de mortalidade, segundo setores censitários classificados pelo Índice de Vulnerabilidade da Saúde, composto por indicadores de saneamento e socioeconômicos. Óbitos por causas naturais e COVID-19 foram obtidos do Sistema de Informação sobre Mortalidade, entre a 10ª e 43ª semana epidemiológica (SE) de 2020. Calculou-se o excesso de mortalidade por modelo de série temporal, considerando as mortes observadas por SE, entre 2015 e 2019, por setor censitário. Taxas de mortalidade (TM) foram calculadas e padronizadas por idade a partir de estimativas populacionais do IBGE.Resultados:
Houve 16,1% (n=1524) de excesso de mortalidade em BH 11,0%, 18,8% e 17,3% nas áreas de baixa, média e elevada vulnerabilidade, respectivamente. As diferenças entre TM observadas e esperadas por causas naturais, padronizadas por idade, foi igual a 59/100.000 habitantes em BH, aumentando de 31 para 77 e 95/100.000, nas áreas de baixa, média e elevada vulnerabilidade, respectivamente. Houve gradiente de aumento com a idade nas TM por COVID-19, variando de 4 a 611/100.000 habitantes entre as idades de 20-39 anos e 75+ anos. A TM por COVID-19 por 100.000 idosos (60+ anos) foi igual a 292, aumentando de 179 para 354 e 476, nos setores de baixa, média e elevada vulnerabilidade, respectivamente.Conclusão:
Desigualdades na mortalidade, mesmo entre idosos, aliadas à baixa oferta de doses, demonstram importância de priorizar áreas socialmente vulneráveis durante a vacinação contra COVID-19.
