## Abstract

Project Abstract
Asthma affects 25 million Americans, and chronic obstructive pulmonary disease (COPD) affects 16 million, 
together costing 130 billion USD annually to the US healthcare system. Asthma is more prevalent in African 
American population (10.6%) than white population (7.7%). Poverty level has an impact as well, with twice as 
much asthma incidence in people below 100% of the poverty threshold as compared to people above 450% of 
the threshold. Racial-ethnic and socioeconomic health disparities in the US due to air pollution exposure are well 
documented and have persisted despite overall decreases in ozone and particulate matter pollution. This 
disproportionate exposure reflects generations of discriminatory practices including racially-segregated 
residential policies that result in communities of color being more frequently located near major sources of air 
pollution, both industrial and transportation-related. The proposed research project seeks to address health 
disparities related to air pollution by enabling self-monitoring of environmental triggers of asthma and other 
respiratory diseases, so that the patients are empowered for self-management of their disease. This study will 
develop and test a wearable sensor array with a small form-factor for monitoring personal exposure to several 
important air pollutants, and then pilot this device in a small panel of African-American adults with physiciandiagnosed asthma. The device will be sensitive to a variety of primary and secondary pollutants from both motorvehicle traffic and industrial emissions. It will employ metal oxide semiconductor sensors to measure ozone, 
nitrogen dioxide, and volatile organic compounds as well as relative humidity and ambient temperature. The 
device will be able to connect to Bluetooth-enabled smartphones for data logging and display purposes, yet it 
will be small enough to be worn on the wrist. We will validate the utility of this device for improving health by
recruiting 20 African-American adults who live in the Atlanta area and have been diagnosed with asthma. These 
participants will use the device to monitor their air pollution exposure for one month. During this month, they will 
also measure their lung function twice per day using a small commercially-available spirometer that we will 
provide them. We will develop a smartphone application that will clearly display air quality data in an intuitive 
color-coded display. The app will also include lung function data from spirometry in a percent-predicted score 
relative to expected values based on age, height, sex and race. The overall goal of this project is to demonstrate 
the feasibility of a wearable device to assist in the identification of air pollution-related asthma triggers and to 
empower asthma patients to improve their health by reducing exposure.
