| Sumario: | There is evidence of a greater COVID-19 mortality burden faced by socioeconomically vulnerable groups; however, some investigations found that poverty was associated with greater case fatality but not greater mortality. Our objective was to analyze the trends in the mortality rates adjusted by age (MRABA) and mortality and case fatality from COVID-19 (MRC and Case Fatality) based on socioeconomic indicators in the province of Cordoba between 2020 and 2022.
A multi-group study (n = 26 departments in Cordoba) was conducted using secondary data sources (provincial statistics, National System of Health Surveillance, 2010 Census). MRABA, MRC, and Case Fatality were developed for 2020 to 2022 and compared based on selected indicators (population with at least one unmet basic need – UBN –, access to sewers, natural gas network, population with no health care coverage or vaccination against COVID-19). The comparison of the rates in the periods was made using the Kruskall-Wallis test and the correlation between the rates every year and the indicators selected was carried out using the Spearman or Pearson method (95% CL), and using Stata v. 17.0 software.
Case fatality was greater in 2020 (2.82%; p < 0.01), while MRC was greater in 2021 (1,53‰; p < 0,01); MRABA in 2021 was greater than in 2020 (6,49‰; p = 0,02). Vaccination coverage for the primary scheme was 87.7% in 2021 and 91.4% in 2022, while for the booster shot, the figures were 14.9% and 58.3% respectively. In 2020, case fatality correlated positively with worse socioeconomic conditions; meanwhile, MRC in 2020 and 2021 correlated with better socioeconomic conditions, whereas in 2022 a positive correlation, though not significant, correlated with lower vaccination coverage and worse socioeconomic conditions.
Different COVID-19 mortality profiles were found according to the stage of the pandemic; at the beginning of the pandemic, socioeconomic vulnerability was associated with greater case fatality but not higher mortality. The decrease in case fatality and MRC may be the result of high vaccination coverage, active immunity, established treatment, and the prevention measures adopted by the population. |
