ClinConnect Summary
This clinical trial, called HEPA, PM2.5, and Cardiometabolic Health, is looking at whether using special air filters (HEPA filters) in homes can help improve health, especially heart and metabolic conditions, by reducing harmful tiny particles (PM2.5) in the air we breathe indoors. The study is currently recruiting participants who are between 65 and 84 years old, do not smoke, and have had a higher body weight in the past. Participants should also live in Los Angeles County and be comfortable speaking either English or Spanish.
If you join the trial, you'll be part of a study where some homes will use these air filters for a longer period. The researchers want to see if this makes a difference in your health. However, you won't be eligible if you have certain health issues like diabetes, active cancer treatment, or if your home has already had HEPA filters installed. This study is important because it could help us understand how to better protect our health from air pollution, especially for older adults.
