Clinical characteristics and comorbidities associated with mortality in patients with COVID-19 in Coahuila (Mexico)

Background and objective: This study aims to describe the characteristics of patients with COVID-19 in a state in northern Mexico and establish the comorbidities associated with mortality. Methods: Patients with COVID-19, divided into survivors and non-survivors, were analyzed. The data were analyzed using the chi-square test, Student's t-test, and Cox's regression model. Results: A total of 17,479 patients were included and mortality rate of 6.3% was reported. Age over 60 years (HR = 8.04; 95% cl 7.03-9.19), diabetes (HR = 1.63; 95% CI 1.40-1.89), high blood pressure (HR = 1.48; 95% CI 1.28-1.72), obesity (HR = 1.37; 95% CI 1.18-1.60) and chronic kidney disease (HR = 2.06; 95% CI 1.64-2.59) were significantly associated with mortality. Conclusions: Diabetes, high blood pressure, obesity, and chronic kidney disease increased mortality among patients with COVID-19 in the population of Coahuila, Mexico. The factor that most contributed to risk of death was age over 60 years. (C) 2021 Elsevier Espana, S.L.U. and Sociedad Espanola de Medicina Interna (SEMI). All rights reserved.
