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%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. 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.
