The Relationship Between Predisposing Risk Factors and COVID-19: An Observational Study

Area of Science:

• Internal Medicine
• Epidemiology
• Public Health

Background:

• Numerous risk factors, including sociodemographic variables and comorbidities, are linked to severe COVID-19.
• Individuals with conditions like diabetes, hypertension, and heart disease face higher risks of severe illness and death.
• Understanding these associations is crucial for managing COVID-19 patient outcomes.

Purpose of the Study:

• To investigate the association between various risk factors and the severity of COVID-19.
• To analyze how the number of comorbidities impacts disease progression and outcomes.
• To identify patient groups requiring prioritized medical attention.

Main Methods:

• A prospective, observational, single-center study involving 1,454 hospitalized patients.
• Patients were categorized into groups based on the absence, single, or multiple comorbidities.
• Risk factors evaluated included age, obesity, diabetes, hypertension, chronic kidney disease (CKD), heart disease, chronic liver disease (CLD), and immunocompromised status.

Main Results:

• A significant association was observed between increasing age, male gender, and COVID-19 severity.
• Comorbidities such as diabetes, hypertension, obesity, CKD, CLD, and heart disease were strongly linked to severe disease.
• Disease severity and mortality increased significantly with the number of comorbidities present.

Conclusions:

• The severity of COVID-19 correlates directly with the number of coexisting risk factors.
• Patients with multiple comorbidities represent a high-risk group requiring proactive management strategies.
• Early identification and intervention in these vulnerable populations can mitigate severe disease and improve survival rates.
