Ethnic disparities in COVID-19 mortality in Mexico: a cross-sectional study based on national data

Abstract

AbstractObjectiveTo analyze the mortality associated with ethnicity, particularly of Indigenous peoples, in a large sample of patients with COVID-19 in Mexico.DesignNational, cross-sectional study.SettingMexico.Participants416546 adult patients; 4178 Indigenous peoples with COVID-19 were the primary population under study.Main outcome measuresThe primary outcome was mortality from COVID-19 up to August 3rd, 2020. Logistic regression was used to calculate odds ratios while adjusting for confounders.ResultsAmong all patients with COVID-19, whether hospitalized or not, a higher proportion of Indigenous peoples died compared to non-Indigenous people (16.5% vs 11.1%, respectively). Among hospitalized patients, a higher proportion of Indigenous peoples died (37.1%) compared to non-Indigenous peoples (36.3%). Deaths outside the hospital were also higher among Indigenous peoples (3.7% vs 1.7%). A higher proportion of Indigenous peoples died in both the private and public health care sectors. The adjusted odds ratio for COVID-19 mortality among Indigenous peoples with COVID-19 was 1.13 (95% confidence interval 1.03 to 1.24). The adjusted odds ratio for COVID-19 mortality among Indigenous peoples with COVID-19 was higher among those who received only ambulatory care (1.55, 95% confidence interval 1.24 to 1.92).ConclusionsIn the large sample of patients with COVID-19, the findings suggest that Indigenous peoples in Mexico have a higher risk of death from COVID-19, especially outside the hospital. These findings suggest Indigenous peoples lack access to care more so than non-Indigenous people during the COVID-19 pandemic in Mexico. More research is needed regarding the impact of the COVID-19 among racial and ethnic minorities in Mexico.
