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.

Study Suggests Linkage Between the Weekly Use of Disinfectants and Cleaning Products and Asthma
In December 2024, a study analyzed long-term exposure to disinfectants and cleaning products (DCPs) and identified five usage profiles among 1,143 German adults aged 19–34. Researchers found that only persistent weekly use of multiple DCPs over time was linked to a higher risk of asthma and wheezing. However, due to wide confidence intervals, uncertainty remains.…

A Systematic Review and Meta-Analysis on Inhaled Reliever Therapies for Asthma
A systematic review and meta-analysis released in October 2024 by JAMA Network of 27 clinical trials (50,496 participants) compared inhaled asthma relievers. Findings show that combining inhaled corticosteroids (ICS) with short-acting β agonists (SABA) or formoterol significantly reduces severe asthma exacerbations and improves asthma control compared to SABA alone. ICS-formoterol showed the greatest benefit, reducing…
