Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Purpose: The purpose of this protocol is to understand how social factors such as psychosocial stress may modify how people respond to air pollution. Ultimately this will help us understand health disparities from poor air quality. Participants: Up to 40 healthy adults,18-33 years old with different perception of stress will participate and complete this study. Procedures (methods): Subjects will be exposed to clean air and to ozone ( 300ppb) for 2 hours in a controlled environment chamber. Cardiac, vascular, pulmonary and cognitive function will be evaluated pre, immediately post and 18 hr post exposure. The primary endpoint will be Heart Rate Variability . Secondary endpoints will include pulmonary function, analysis of blood clotting/coagulation factors, biomarkers of stress, cognitive function, radial artery pulse wave measurements and analysis of soluble factors present in plasma.
