Table 3.
Comparison of crude and adjusted odds ratio of African American COVID-19 death and incidence between counties with higher than 40% AA population (high risk group) and others (lower risk group) in Louisiana between March 1, 2020 and March 1, 2021
| Model summary | OR | 95% CI | p value |
|---|---|---|---|
| A. African American death rate | |||
| Model A1 (crude) | 1.7 | (1.2, 2.4) | 0.002 |
| Model A2 (diabetes, hypertension)* | 1.5 | (1.1, 2.3) | 0.016 |
| Model A3 (75th percentile of diabetes, hypertension)* | 1.8 | (1.1, 3.0) | 0.02 |
| B. African American cumulative incidence rate | |||
| Model B1 (crude) | 1.9 | (1.6, 2.4) | < 0.0001 |
| Model B2 (diabetes, obesity)** | 1.6 | (1.3, 2.0) | < 0.0001 |
| Model B3 (75th percentile of diabetes, obesity)** | 2.3 | (1.6, 3.2) | < 0.0001 |
| Model B4 (asthma, COPD)** | 1.6 | (1.3, 2.1) | < 0.0001 |
| Model B5 (75th percentile of asthma, COPD)** | 1.8 | (1.2, 2.7) | 0.003 |
| Model B6 (heart disease and hypertension)** | 1.6 | (1.3, 2.1) | < 0.0001 |
| Model B7 (75th percentile of heart disease and hypertension)** | 1.8 | (1.2, 2.7) | 0.008 |
| Model B8 (kidney disease)** | 1.7 | (1.3, 2.1) | < 0.0001 |
| Model B9 (75th percentile of kidney disease)** | 2.1 | (1.5, 2.9) | < 0.0001 |
*Role of diabetes, hypertension adjusting for BMI, and household size
**Role of diabetes and obesity (models B2–B3); asthma and COPD (models B4–B5); heart disease and hypertension (models B6–B7); kidney disease (models B8–B9), adjusting for BMI, income, poverty, and household size
