Association between air pollution in Lima and the high incidence of COVID-19: findings from a post hoc analysis

BMC Public Health

Table 4 Association between the COVID-19 case fatality rate and previous PM_2.5 concentrations in 24 districts of Lima

COVID-19 fatality rate	Crude coefficient	95%CI		Adjusted coefficient	95%CI
PM_2.5	− 0.014	− 0.056	0.029	0.01	−0.047	0.068
Sex ratio	−0.303	−2.569	1.963	−1.956	−5.207	1.293
Age	0.043	−0.049	0.135	0.035	−0.039	0.11
Food markets	1.082	−0.257	2.422	0.0054	−0.001	0.012
Population density	0.00001	−6.21e-⁰⁶	.000035	0.00003	−2.60e-⁰⁶	0.00006

The model was adjusted for PM_2.5 level, sex ratio (female cases: male cases), age [years], and food markets (number of food markets per district and population density at the COVID-19 diagnosis). Data for the PM_2.5 level (μg/m³) correspond to the average data per district obtained daily from 2012 to 2016
