Abstract
The coronavirus disease (COVID-19) has revealed existing health inequalities in racial and ethnic minority groups in the US. This work investigates and quantifies the non-uniform effects of geographical location and other known risk factors on various ethnic groups during the COVID-19 pandemic at a national level. To quantify the geographical impact on various ethnic groups, we grouped all the states of the US. into four different regions (Northeast, Midwest, South, and West) and considered Non-Hispanic White (NHW), Non-Hispanic Black (NHB), Hispanic, Non-Hispanic Asian (NHA) as ethnic groups of our interest. Our analysis showed that infection and mortality among NHB and Hispanics are considerably higher than NHW. In particular, the COVID-19 infection rate in the Hispanic community was significantly higher than their population share, a phenomenon we observed across all regions in the US but is most prominent in the West. To gauge the differential impact of comorbidities on different ethnicities, we performed cross-sectional regression analyses of statewide data for COVID-19 infection and mortality for each ethnic group using advanced age, poverty, obesity, hypertension, cardiovascular disease, and diabetes as risk factors. After removing the risk factors causing multicollinearity, poverty emerged as one of the independent risk factors in explaining mortality rates in NHW, NHB, and Hispanic communities. Moreover, for NHW and NHB groups, we found that obesity encapsulated the effect of several other comorbidities such as advanced age, hypertension, and cardiovascular disease. At the same time, advanced age was the most robust predictor of mortality in the Hispanic group. Our study quantifies the unique impact of various risk factors on different ethnic groups, explaining the ethnicity-specific differences observed in the COVID-19 pandemic. The findings could provide insight into focused public health strategies and interventions.
Highlights
Numerous researchers have found various comorbidities and other risk factors affecting the spread and prognosis of coronavirus disease (COVID-19)
We aim to investigate the following in this study: 1. Does a geographical location have different impact on COVID-19 infection and mortality rates for different ethnicities?
Results of the Linear Models With Infection and Mortality Rates as Response Variables for Each Ethnic Group In Table 6 we depict the linear models with infection rate and mortality rate as response variables for Non-Hispanic White (NHW)
Summary
Numerous researchers have found various comorbidities and other risk factors affecting the spread and prognosis of coronavirus disease (COVID-19). Recent work by many researchers has demonstrated that the COVID-19 pandemic has affected marginalized ethnicities more severely. We hypothesize that the risk factors for COVID-19 must have affected different ethnic groups in a distinctive manner. We aim to quantify the differential effect of risk factors on different ethnicities.
