Studies & Reports
One of our core strategies at RAMP is to keep the asthma field abreast of best practices, timely opportunities, and emerging research in order to build capacity for reducing the inequitable burden of asthma. We do this by cultivating an extensive hub of asthma-related information across a wide range of topics, including asthma management and healthcare, housing, air pollution, schools, the built environment, and more.
The majority of studies and reports that you’ll see below were published by partner organizations, agencies, and research institutions. To specifically see resources created by RAMP, check out RAMP Tools & Publications.

National Population-Based Cohort Study Evaluating the Connection Between New-Onset Asthma and COVID-19
Since the COVID-19 pandemic, concerns have arisen about potential long-term health effects. An article titled, “Increased Risk of New-Onset Asthma After COVID-19: A Nationwide Population-Based Cohort Study,” used the Korean National Health Insurance claim-based database to understand the connection between COVID-19 diagnosis, COVID-19 vaccination, and new-onset asthma or lack thereof. The results showed that individuals…
