Could a greener city mean a healthier you?

The University of Louisville has invited people ages 25 to 70 in six South Louisville neighborhoods to participate in the HEAL Study. This study is part of the Green Heart Project and will investigate how neighborhood greenness impacts the health of the people in these communities.

What’s involved in participation?

Participation in the HEAL Study involves two to three health screening appointments.*

If you sign up to be a part of the HEAL Study, we will assess your baseline health in 2021. We will ask you to fill out surveys about your health, stress level, lifestyle and relationships, and disease risk. We will collect samples from you that allow us to assess your exposure to pollution and other health metrics.

In 2022, we will repeat the same measures to reassess your health. Appointments are scheduled in advance and take 60 to 90 minutes. Compensation for your time will be provided.

*If you enrolled in the HEAL Study in 2018 or 2019, you will have three appointments in total. Your first appointment was in 2018 or 2019, your second will be in 2021, and your third in 2022. Because of the COVID-19 pandemic, we must reassess participants’ health after this event. If you enroll in the HEAL Study in the summer of 2021, you will have two appointments, the first in 2021 and the second in 2022.

Why Louisville?

Right now, the greenness of our city is definitely not what it could be.

  • Louisville has received an F from the American Lung Association for annual ozone days since 2012
  • Our air quality ranks among the worst in Kentucky
  • Our tree canopy loses about 54,000 trees per year

But we view this as an opportunity. Your participation in this study could provide new information on the links between nature and health. This information could identify new ways to help prevent heart disease, diabetes, and obesity without the use of medications. The HEAL Study is also an opportunity to improve your neighborhood and potentially develop a scientifically backed “greenprint” for creating healthy cities. We hope you’ll decide to join us.
