Comorbidities associated with adult asthma according to severity: analysis of data from the National Health Insurance Sharing Service

Highlight box

Key findings

• This study found that patients with asthma have a higher risk of developing chronic diseases.

• Severe asthma (SA) was associated with a greater incidence of comorbidities, including cardiovascular and cerebrovascular diseases.

What is known and what is new?

• Asthma is associated with various comorbidities, including rhinitis, gastroesophageal reflux disease, and psychiatric disorders, which can impact the clinical outcome of the disease.

• This manuscript adds new insights by analyzing large-scale national health insurance data, demonstrating that the severity of asthma significantly influences the prevalence and risk of these comorbidities. SA patients have a notably higher risk compared to those with non-SA.

What is the implication, and what should change now?

• Clinicians should consider the impact of comorbid diseases when managing asthma patients, particularly those with SA. There is a need for a more comprehensive approach in treating asthma that includes screening and managing these associated comorbidities to improve patient outcomes.
