Background And ObjectiveThis study aims to describe the characteristics of patients with COVID-19 in a state in northern Mexico and establish the comorbidities associated with mortality.MethodsPatients 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.ResultsA total of 17,479 patients were included and mortality rate of 6.3% was reported. Age over 60 years (HR = 8.04; 95% CI 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.ConclusionsDiabetes, 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.© 2021 Elsevier España, S.L.U. and Sociedad Española de Medicina Interna (SEMI). All rights reserved.
